Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable national, state and local laws,
safety regulations, standards and
ordinances.
WARNING
Do not lend or rent your power tool
without the instruction manual. Be sure
that anyone using it understands the
information contained in this manual.
WARNING
The use of this machine may be
hazardous. The pole pruner chain has
many sharp cutters. If the cutters contact
your flesh, they will cut you, even if the
chain is not moving.
WARNING
Do not cut any material other than wood
or wooden objects. Use your pole pruner
for limbing only.
Do not use it for other purposes, since
misuse may result in personal injury or
property damage, including damage to
the machine.
WARNING
Minors should never be allowed to use
this power tool. Bystanders, especially
children, and animals should not be
allowed in the area where it is in use.
WARNING
To reduce the risk of injury to bystanders
and damage to property, never let your
power tool run unattended. When it is
not in use (e. g. during a work break),
shut it off and make sure that
unauthorized persons do not use it.
Most of these safety precautions and
warnings apply to the use of all STIHL
pole pruners. Different models may have
different parts and controls. See the
appropriate section of your instruction
manual for a description of the controls
and the function of the parts of your
model.
Safe use of a pole pruner involves
1. the operator
2. the power tool
3. the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol, etc.) which might impair vision,
dexterity or judgment. Do not operate
this machine when you are fatigued.
WARNING
Be alert – if you get tired, take a break.
Tiredness may result in loss of control.
Working with any power tool can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
this machine.
WARNING
Prolonged use of a power tool (or other
machines) exposing the operator to
vibrations may produce whitefinger
disease (Raynaud's phenomenon) or
carpal tunnel syndrome.
These conditions reduce the hand's
ability to feel and regulate temperature,
produce numbness and burning
sensations and may cause nerve and
circulation damage and tissue necrosis.
All factors which contribute to
whitefinger disease are not known, but
cold weather, smoking and diseases or
physical conditions that affect blood
vessels and blood transport, as well as
high vibration levels and long periods of
Safety Precautions and
Working Techniques
Because a pole pruner is
a high-speed, fast-cut-
ting power tool with an
extended reach, special
safety precautions must
be observed to reduce
the risk of personal injury.
It is important that you
read, fully understand
and observe the following
safety precautions and
warnings. Read the
instruction manual and
the safety precautions
periodically. Careless or
improper use may cause
serious or fatal injury.

HT 102, HT 103, HT 132, HT 133

exposure to vibration are mentioned as
factors in the development of whitefinger
disease. In order to reduce the risk of
whitefinger disease and carpal tunnel
syndrome, please note the following:
–Most STIHL power tools are
available with an anti-vibration
("AV") system designed to reduce
the transmission of vibrations
created by the machine to the
operator's hands. An AV system is
recommended for those persons
using power tools on a regular or
sustained basis.
–Wear gloves and keep your hands
warm.
–Keep the AV system well
maintained. A power tool with loose
components or with damaged or
worn AV elements will tend to have
higher vibration levels.
–Maintain a firm grip at all times, but
do not squeeze the handles with
constant, excessive pressure. Take
frequent breaks.
All the above-mentioned precautions do
not guarantee that you will not sustain
whitefinger disease or carpal tunnel
syndrome. Therefore, continual and
regular users should closely monitor the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.
WARNING
The ignition system of the STIHL unit
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce the risk of serious or fatal injury,
persons with a pacemaker should
consult their physician and the
pacemaker manufacturer before
operating this tool.
Proper Clothing
WARNING
To reduce the risk of injury, the operator
should wear proper protective apparel.
WARNING
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Avoid loose-fitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become caught on branches,
brush or the moving parts of the unit.
Secure hair so it is above shoulder level.
THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts".
To reduce the risk of
injury to your eyes never
operate your power tool
unless wearing goggles
or properly fitted protec-
tive glasses with
adequate top and side
protection complying with
ANSI Z 87.1 "+" (or your
applicable national stand-
ard). To reduce the risk of
injury to your face STIHL
recommends that you
also wear a face shield or
face screen over your
goggles or protective
glasses.
Wear an approved safety
hard hat to reduce the
risk of injury to your head.
Power tool noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
protect your hearing.
Continual and regular
users should have their
hearing checked
regularly.
Always wear heavy-duty
work gloves (e.g. made of
leather or other wear
resistant material) when
handling the machine
and the cutting tool.
Heavy-duty, nonslip
gloves improve your grip
and help to protect your
hands.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs. Do not wear
shorts, sandals or go
barefoot.
Good footing is very
important. Wear sturdy
boots with nonslip soles.
Steel-toed safety boots
with cut retardant inserts
are recommended.

WARNING
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
If this tool is subjected to unusually high
loads for which it was not designed (e. g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
THE USE OF THE POWER TOOL
Transporting the Power Tool
This power tool should be carried only in
a horizontal position. Grip the shaft in a
manner that the machine is balanced
horizontally. Keep the hot muffler away
from your body and the cutting
attachment behind you.
WARNING
Accidental acceleration of the engine
can cause the chain to rotate and cause
serious injuries.
Always switch off the engine and fit the
scabbard over the cutting attachment
before transporting the power tool over
long distances. When transporting it in a
vehicle, properly secure it to prevent
turnover, fuel spillage and damage to
the unit.
Fuel
Your STIHL power tool uses an oil-
gasoline mixture for fuel (see the "Fuel"
chapter in this instruction manual).
WARNING
Fueling Instructions
WARNING
To reduce the risk of fire and serious
personal injury, always place the power
tool on the ground before attempting to
fuel the machine.
WARNING
Pick a Safe Location
To reduce the risk of fire and explosion,
fuel your power tool in a well-ventillated
area, outdoors away from flames, pilot
lights, heaters, electric motors, and
other sources of ignition. Vapors can be
ignited by a spark or flame many feet
away. Select bare ground for fueling and
move at least 10 feet (3 m) from the
fueling spot before starting the engine.
Wipe off any spilled fuel before starting
your power tool. Take care not to get fuel
on your clothing. If this happens, change
your clothing immediately.
Allow the Power Tool to Cool Before
Removing the Fuel Cap
WARNING
Gasoline vapor pressure may build up
inside the fuel tank. The amount of
pressure depends on a number of
factors such as the fuel used, altitude
and temperature. To reduce the risk of
burns and other personal injury from
390BA000 KN
Gasoline is an extremely
flammable fuel. If spilled
and ignited by a spark or
other ignition source, it
can cause fire and seri-
ous burn injury or
property damage. Use
extreme caution when
handling gasoline or fuel
mix. Do not smoke or
bring any fire or flame
near the fuel or the power
tool. Note that combus-
tible fuel vapor may
escape from the fuel
system.

HT 102, HT 103, HT 132, HT 133
English

escaping gas, vapor and fumes, always
shut off the engine and allow it to cool
before removing the fuel cap.
The engine is air cooled. When it is shut
off, cooling air is no longer drawn across
the cylinder and engine temperatures
will rise for several minutes before
starting to cool. In hot environments,
cooling will take longer. To reduce the
risk of burns and other personal injury
from escaping gas, vapor and fumes,
allow the power tool to cool. If you need
to refuel before completing a job, turn off
the machine and allow the engine to cool
before opening the fuel tank.
Fuel Spraying or “Geysering”
WARNING
Removing the cap on a pressurized fuel
tank can result in gasoline, vapors and
fumes being forcefully sprayed out from
the fuel tank in all directions. The
escaping gasoline, vapors or fumes can
cause serious personal injury, including
fire and burn injury, or property damage.
Sometimes also referred to as "fuel
geysering," fuel spraying is an expulsion
of fuel, vapors and fumes which can
occur in hot conditions, or when the
engine is hot, and the tank is opened
without allowing the power tool to cool
adequately. It is more likely to occur
when the fuel tank is half full or more.
Pressure is caused by fuel and heat and
can occur even if the engine has not
been running. When gasoline in the fuel
tank is heated (by ambient
temperatures, heat from the engine, or
other sources), vapor pressure will
increase inside the fuel tank.
Some blends of gasoline, particularly
those designed for use in winter, are
more volatile and may cause tanks to
pressurize more quickly or create
greater pressure. At higher altitudes,
fuel tank pressurization is more likely.
How to Avoid Fuel Spraying
Removing the fuel cap on a pressurized
tank can result in gasoline, vapors and
fumes being forcefully sprayed out from
the fuel tank in all directions. To reduce
the risk of burns, serious injuries or
property damage from fuel spraying:
–Follow the fueling instructions in this
chapter.
–Always assume your fuel tank is
pressurized.
–Allow the power tool to cool before
removing the fuel cap.
–In hot environments, cooling will
take longer.
–The engine is air cooled. When it is
shut off, cooling air is no longer
drawn across the cylinder and the
engine temperature will rise for
several minutes before starting to
cool.
After the power tool has cooled
appropriately, follow the safety
instructions in this chapter for removing
the cap.
Never remove the fuel filler cap by
turning it directly to the open position.
First check for residual pressure in the
tank by slowly turning the cap
approximately 1/2 turn counter-
clockwise. The cap should be held in
place by the threads while allowing
residual vapor/pressure to be relieved.
Once the fumes or vapor have been
relieved, turn the cap further until it can
be removed from the tank opening.
Use only good quality fuel that is
appropriate for the season (summer v.
winter blends). Some blends of
gasoline, particularly winter blends, are
more volatile and can contribute to fuel
spraying.
Removing the Threaded Fuel Filler Cap
WARNING
After allowing the power tool to cool,
remove the fuel filler cap slowly and
carefully to allow any remaining
pressure build-up in the tank to release:
–While maintaining steady,
downward pressure, slowly turn the
cap approximately 1/2 turn counter-
clockwise.
–If any significant venting occurs,
immediately re-seal the tank by
turning the cap clockwise to the
closed position. Allow the power
tool to cool further before
attempting to open the tank.
–Turn the cap to the open position
only after the contents of the tank
are no longer under pressure.
–Never remove the cap by turning it
directly to the open position. First
allow the power tool to cool
adequately and then release any
residual pressure by slowly turning it
approximately 1/2 turn counter-
clockwise.
–Never attempt to remove the cap
while the engine is still hot or
running.

Installing the Threaded Fuel Filler Cap
WARNING
Damaged or Broken Cap
If your fuel cap does not tighten properly,
it may be damaged or broken. Stop
using the power tool and take it to your
authorized STIHL dealer for repair.
Vapor Lock
WARNING
Vapor lock occurs when fuel in the fuel
line or carburetor vaporizes, causing
bubbles to block the free flow of liquid
fuel into the carburetor. Vapor lock
cannot be relieved or affected by
opening the fuel tank. Removing the fuel
filler cap without first allowing the power
tool to cool adequately can result in fuel
spraying. Always follow the instructions
in this section when removing the fuel
cap.
To relieve vapor lock:
–Place the Choke Lever in the cold
start position g and pull the starter
cord approximately 20 times to clear
the vapor and send liquid fuel into
the carburetor.
–To start the power tool, move the
Choke Lever to the starting throttle
position < and pull the starter cord
approximately 10 times.
–If your power tool will not restart, or
if vapor lock occurs again, the
power tool is being used in
conditions too extreme for the fuel
being used. Discontinue use and let
the engine cool completely before
attempting to start the power tool.
Before Operation
Take off the chain guard (scabbard) and
inspect the pole pruner for proper
condition and operation. (See the
maintenance chart near the end of the
instruction manual.)
WARNING
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger lockout, stop switch and cutting
attachment. The throttle trigger must
move freely and always spring back to
the idle position. Never attempt to
modify the controls or safety devices.
WARNING
Check fuel system for leaks, especially
the visible parts, e.g., filler cap, hose
connections, manual fuel pump (only for
power tools equipped with a manual fuel
pump). Do not start the engine if there
are leaks or damage – risk of fire. Have
the power tool repaired by a STIHL
servicing dealer before using it.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely and
securely assembled.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
For proper assembly of the bar and
chain follow the procedure described in
the chapter "Mounting the Bar and
Chain" of this instruction manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch.
WARNING
Proper chain tension is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your
manual. Always make sure the hex
nut(s) for the sprocket cover is (are)
tightened securely after tensioning the
chain. Check chain tension once more
Unit vibrations can cause
an improperly tightened
fuel filler cap to loosen or
come off and spill quanti-
ties of fuel. To reduce the
risk of fuel spillage and
fire, tighten the fuel filler
cap by hand with as
much force as possible.

HT 102, HT 103, HT 132, HT 133
English

after having tightened the nut(s). Never
start the pole pruner with the sprocket
cover loose.
Adjust carrying harness and hand grip to
suit your size before starting work.
For specific starting instructions, see the
appropriate section of your instruction
manual.
Starting
To reduce the risk of serious personal
injury from fire, start the engine at least
10 feet (3 m) from the fueling spot,
outdoors only.
Start and operate your pole pruner
without assistance.
Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
For specific starting instructions, see the
appropriate section of your manual.
Place the pole pruner on firm ground or
other solid surface in an open area or, in
the alternative, as shown in the above
picture. Maintain good balance and
secure footing.
WARNING
To reduce the risk of injury from loss of
control, do not attempt to "drop start"
your power tool. Drop starting means
pushing the machine away from the
operator, or allowing it to drop toward
the ground, while pulling on the starter
grip. This method is very dangerous
because you may lose control of the
machine.
WARNING
To reduce the risk of injury from loss of
control be absolutely sure that the guide
bar and chain are clear of you and all
other obstructions and objects, including
the ground, because when the engine
starts at starting-throttle, engine speed
will be fast enough for the clutch to
engage the sprocket and turn the chain.
Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to
idle.
With the engine running only at idle,
attach the power tool to the spring hook
of your harness (see appropriate
chapter of this manual).
WARNING
When you pull the starter grip, do not
wrap the starter rope around your hand.
Do not let the grip snap back, but guide
the starter rope to permit the rope to
rewind properly. Failure to follow this
procedure may result in injury to your
hand or fingers and may damage the
starter mechanism.
Important Adjustments
WARNING
To reduce the risk of personal injury
from loss of control or contact with the
running cutting tool, do not use your unit
with incorrect idle adjustment. At correct
idle speed, the saw chain should not
move. For directions on how to adjust
idle speed, see the appropriate section
of your instruction manual.
If you cannot set the correct idle speed,
have your STIHL dealer check your
power tool and make proper
adjustments and repairs.
Proper chain tension is very important at
all times. Check it at regular intervals
(during work breaks and only when the
pole pruner is shut off). If the chain
becomes loose while cutting, switch off
the engine and then tighten. Never try to
tighten the chain while the engine is
running.
During Operation
Holding and Controlling the Power Tool
Always hold the unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
around the handles.

Place your left hand on the shaft and
your right hand on rear grip and throttle
trigger. Left-handers must follow these
instructions, too. Keep your hands in this
position to help maintain control of your
pole pruner while working at all times.
WARNING
Never attempt to operate your power
tool with one hand. Loss of control of the
power tool resulting in serious or fatal
injury may result.
WARNING
In order to properly control your pole
pruner, always maintain good balance
and a firm foothold. Never work on a
ladder, in a tree or on any other insecure
support. Never hold the machine above
shoulder height. Do not overreach.
When working at a height above 15 feet
(4.5 m) use a lift bucket. For pole pruner
with adjustable shaft, expand the shaft
only as far as necessary for the intended
application.
WARNING
Special care must be taken in slippery
conditions (wet ground, snow) and in
difficult, overgrown terrain. Watch for
hidden obstacles such as tree stumps,
roots, rocks, holes and ditches to avoid
stumbling. For better footing, clear away
fallen branches, scrub and cuttings. Be
extremely cautious when working on
slopes or uneven ground.
WARNING
Take extreme care in wet and freezing
weather (rain, snow, ice). Put off the
work when the weather is windy, stormy
or rainfall is heavy.
Working Conditions
Operate and start your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
WARNING
WARNING
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
390BA026 KN
As soon as the engine is
running, this machine
generates toxic exhaust
fumes containing chemi-
cals, such as unburned
hydrocarbons (including
benzene) and carbon
monoxide, that are
known to cause respira-
tory problems, cancer,
birth defects, or other
reproductive harm and
other injuries. Some of
the gases (e. g. carbon
monoxide) may be color-
less and odorless and
can cause asphyxiation
or death very quickly. To
reduce the risk of serious
or fatal injury/illness from
inhaling toxic fumes,
never run the machine
indoors or in poorly venti-
lated locations. If exhaust
fumes become concen-
trated due to insufficient
ventilation, clear obstruc-
tions from work area to
permit proper ventilation
before proceeding and /
or take frequent breaks to
allow fumes to dissipate
before they become
concentrated.

Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work
practices, such as always cutting with a
properly sharpened chain (which
produces wood chips rather than fine
dust) and operating the unit so that the
wind or operating process directs any
dust raised by the power tool away from
the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust
("particulate matter"). When the
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH /
MSHA for the type of dust encountered.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. If you have any reason to
believe that you might be cutting
asbestos, immediately contact your
employer or a local OSHA
representative.
WARNING
In order to reduce the risk of personal or
even fatal injury to bystanders from
falling objects or inadvertent contact with
the moving chain of your power tool
always keep bystanders at least 50 feet
(15 m) away when the power tool is
running.
WARNING
Even though bystanders should be kept
away from the running saw, never work
alone. Keep within calling distance of
others in case help is needed.
Stop the engine immediately if you are
approached.
DANGER
Electricity can jump from one point to
another by means of arcing. Higher
voltage increases the distance electricity
can arc. Electricity can also move
through branches, especially if they are
wet. Maintain a clearance of at least
50 feet (15 m) between the pole pruner
(including any branches it is contacting)
and any electrical line carrying live
current. Before working with less
clearance, contact your electric utility
and make sure the current is turned off.
Operating Instructions
WARNING
Do not operate your power tool using the
starting throttle position, as you do not
have control of the engine speed.
In the event of an emergency, switch off
the engine immediately by pressing the
stop switch.
WARNING
To reduce the risk of cut injuries, keep
hands and feet away from the saw
chain. Never touch a moving chain with
your hand or any other part of your body.

The saw chain continues to move for a
short period after the throttle trigger is
released (inertia effect).
Accelerating the engine while the chain
is blocked increases the load and will
cause the clutch to slip continuously.
This may result in overheating and
damage to important components (e. g.
clutch, polymer housing components) –
which can then increase the risk of injury
from the chain moving while the engine
is idling.
WARNING
If the chain becomes clogged, always
turn off the engine and make sure the
chain has stopped before cleaning.
Make sure that the saw chain does not
touch any foreign materials such as
rocks, fences, nails and the like. Such
objects may be flung off and injure the
operator or bystanders, or damage the
saw chain.
WARNING
Prior to limbing, clear the working area
from interfering limbs and brush. Then,
establish an escape area away from
where the cut limbs can fall, and remove
all obstacles.
Keep work area clear – move away
fallen limbs. Place all tools and
equipment at a safe distance from the
branches being limbed, but not in the
escape area.
WARNING
Always observe the general condition of
the tree. Look for decay and rot in the
trunk and branches. If it is rotted inside,
it could snap and fall toward the operator
while being cut. Also look for broken or
dead branches which could vibrate
loose and fall on the operator. If branch
is thick or heavy, make a shallow relief
cut on the bottom of the branch before
cutting down from the top to help prevent
splitting of the branch. See chapter on
"Using the Unit".
WARNING
To reduce the risk of severe or even fatal
injury from falling objects do not cut
vertically above your body. Hold the pole
pruner at an angle of not more than 60°
from the horizontal level (see picture).
Objects may fall in unexpected
directions. Do not stand directly
underneath the limb being cut!
Watch for falling wood! As soon as the
limbed branch starts to fall, step aside
and keep a sufficient distance away from
the falling wood.
WARNING
Always pull the unit out of the cut with
the chain running to reduce the
possibility of pinching the cutting
attachment. Don't put pressure on the
pole pruner when reaching the end of a
cut. The pressure may cause the bar
and rotating chain to pop out of the cut or
kerf, go out of control and strike some
other object.
If the bar becomes pinched and caught
in the branch so that the chain can no
longer move, shut off the pole pruner
and carefully move the branch to open
the pinch and release the bar.
WARNING
If a rotating saw chain strikes a rock or
other hard object, sparks may be
created, which can ignite flammable
materials under certain circumstances.
Flammable materials can include dry
vegetation and brush, particularly when
weather conditions are hot and dry.
When there is a risk of fire or wildfire, do
not use a power tool around flammable
materials or around dry vegetation or
brush. Contact your local fire authorities
or the U.S. Forest Service if you have
any question about whether vegetation
and weather conditions are suitable for
the use of a pole pruner.
WARNING
Never modify your muffler. Any
modification could cause an increase in
heat radiation, sparks or sound level,
thereby increasing the risk of fire, burn
injury or hearing loss. You may also
permanently damage the engine. STIHL
246BA030 KN

HT 102, HT 103, HT 132, HT 133

recommends having your muffler
serviced and repaired by a STIHL
servicing dealer.
WARNING
The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
hot for a while after stopping the engine.
To reduce risk of burns, do not touch the
muffler and other parts while they are
hot. Keep the area around the muffler
clean. Remove excess lubricant and all
debris such as pine needles, branches
or leaves. Let the engine cool down
sitting on concrete, metal, bare ground
or solid wood (e.g. the trunk of a felled
tree) away from any combustible
substances.
WARNING
An improperly mounted or damaged
cylinder housing or a
damaged/deformed muffler shell may
interfere with the cooling process of the
muffler. To reduce the risk of fire or burn
injury, do not continue work with a
damaged or improperly mounted
cylinder housing or a
damaged/deformed muffler shell.
Your muffler is furnished with a spark
arresting screen designed to reduce the
risk of fire from the emission of hot
particles. Never operate your unit with a
missing or damaged spark arresting
screen. If your gas/oil mix ratio is correct
(i.e., not too rich), this screen will
normally stay clean as a result of the
heat from the muffler and need no
service or maintenance. If you
experience loss of performance and you
suspect a clogged screen, have your
muffler maintained by a STIHL servicing
dealer. Some state or federal laws or
regulations may require a properly
maintained spark arrestor for certain
uses. See the "Maintenance, Repair and
Storing" section of these Safety
Precautions. Remember that the risk of
a brush or forest fire is greater in hot or
dry conditions.
Reactive Forces
WARNING
Reactive forces may occur any time the
chain is rotating.The force used to cut
wood can be reversed and work against
the operator. If the rotating chain is
suddenly stopped by contact with any
solid object such as a branch or is
pinched, the reactive forces may occur
instantly. These reactive forces may
result in loss of control, which, in turn,
may cause personal injury. An
understanding of the causes of these
reactive forces may help you avoid the
element of surprise and loss of control.
Because of the design of the pole
pruner, the reactive forces experienced
when working with it are generally not as
severe as those encountered with a
chainsaw. Nevertheless, you should
always maintain a proper grip and good
footing to control the power tool when
you experience such forces.
The most common reactive forces are:
–kickback,
–pushback,
–pull-in.
Kickback
Kickback may occur when the moving
saw chain near the upper quadrant of
the bar nose contacts a solid object or is
pinched.
The reaction of the cutting force of the
chain causes a rotational force on the
pole pruner in the direction opposite to
the chain movement. This may cause
the bar to move upward.
To Avoid Kickback
The best protection from kickback is to
avoid kickback situations:
1. Be aware of the location of the guide
bar nose at all times.
2. Never let the nose of the guide bar
contact any object. Do not cut limbs
with the nose of the guide bar. Be
especially careful near wire fences
and when cutting small, tough
limbs, which may easily catch the
chain.
3. Cut only one limb at a time.
A = Pull-in
002BA230 KN

HT 102, HT 103, HT 132, HT 133
English
13
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the chain pulls the pole
pruner forward.
Pull-in frequently occurs when the chain
is not rotating at full speed before it
contacts the wood.
To Avoid Pull-in
1. Be alert to forces or situations that
may cause material to pinch the
chain at the bottom of the bar.
2. Always start a cut with the chain
rotating at full speed.
B = Pushback
Pushback occurs when the chain on the
top of the bar is suddenly stopped when
it is pinched, caught or encounters a
foreign object in the wood. The reaction
of the chain may drive the pole pruner
rapidly straight back toward the
operator. Pushback frequently occurs
when the top of the bar is used for
cutting.
To Avoid Pushback
1. Be alert to forces or situations that
may cause material to pinch the
chain at the top of the bar.
2. Do not cut more than one limb at a
time.
3. Do not twist the bar when
withdrawing it from an underbuck
cut because the chain can pinch.
MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair of
the emission control devices and
systems may be performed by any
nonroad engine repair establishment or
individual. However, if you make a
warranty claim for a component which
has not been serviced or maintained
properly, STIHL may deny coverage.
WARNING
STIHL recommends the use of STIHL
replacement parts for maintenance and
repair. Use of parts manufactured by
others may be extremely dangerous and
could result in serious or fatal injury.
Strictly follow the maintenance and
repair instructions in the appropriate
sections of this instruction manual.
Please refer to the maintenance chart in
this manual.
WARNING
Always stop the engine and make sure
that the chain is stopped before doing
any maintenance or repair work or
cleaning the power tool. Do not attempt
any maintenance or repair work not
described in this instruction manual.
STIHL recommends that you have such
work performed by your STIHL servicing
dealer.
Wear gloves when handling or
performing maintenance on the cutting
attachment.
WARNING
To reduce the risk of fire and burn injury
or property damage, use only spark
plugs authorized by STIHL. Always
press spark plug boot snugly onto spark
plug terminal of the proper size. (Note: If
terminal has detachable SAE adapter
nut, it must be securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire. Keep the spark plug clean and
make sure the ignition lead is in good
condition.
WARNING
Never test the ignition system with the
ignition wire boot removed from the
spark plug or with a removed spark plug,
since uncontained sparking may cause
a fire.

WARNING
Do not operate your power tool if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Your muffler is equipped with a spark-
arresting screen to reduce the risk of
fire; never operate your power tool if the
screen is missing, damaged or clogged.
Remember that the risk of a brush or
forest fire is greater in hot or dry
weather.
In California, it is a violation of § 4442 or
§ 4443 of the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine’s
exhaust system is equipped with a
complying spark arrester that is
maintained in effective working order.
The owner/operator of this product is
responsible for properly maintaining the
spark arrester. Other states or
governmental entities/agencies, such as
the U.S. Forest Service, may have
similar requirements. Contact your local
fire agency or forest service for the laws
or regulations relating to fire protection
requirements.
WARNING
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut or burn marks appear on the
wood. Keep chain at proper tension.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
For maintenance items please also refer
to the maintenance chart in this manual.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
Store the power tool in a dry and high or
locked location out of reach of children.
Before storing for longer than a few
days, always empty the fuel tank. See
chapter "Storing the machine" in this
manual.
Store fuel and chain oil in approved and
properly labeled safety-type canisters
only. Take care when handling gasoline!
Avoid direct contact with the skin and
avoid inhaling fuel vapor!
Preparations
NWear suitable protective clothing,
observe safety precautions.
NAdjust telescoping shaft to the
required length (HT 103, HT 133
only).
NStart the engine.
NPut on the shoulder strap.
Cutting Sequence
To allow branches to free fall, always cut
the lower branches first. Prune heavy
branches (large diameter) in several
controllable pieces.
WARNING
Never stand directly underneath the
branch you are cutting – be wary of
falling branches. Note that a branch may
spring back at you after it hits the ground
– risk of injury.
Disposal
Do not throw cuttings into the garbage
can – they can be composted.
Working Techniques
Hold the control handle with your right
hand, and the shaft with your left hand.
Your left arm should be extended to the
most comfortable position.
Using the Unit

HT 102, HT 103, HT 132, HT 133
English
15
HT 102, HT 132
Always hold the shaft with your left hand
in the area of the handle hose.
The shaft should always be held at an
angle of 60° or less.
The least tiring working position is a tool
angle of 60°.
Any lesser angle may be used to suit the
situation.
Cross-cut
To avoid pinching the bar in the cut,
position the cutting attachment with the
housing against the branch and then
perform the cross-cut from the top
downwards.
Relieving cut
To avoid tearing the bark on thick
branches, always start by performing a
relieving cut (1) on the underside of the
branch.
NTo do this, apply the cutting
attachment and pull it across the
bottom of the branch in an arc as far
as the bar nose.
NPerform the cross cut (2) – position
the bar with the housing against the
branch.
Flush-cutting thick branches
If branch diameter is more than
10 cm (4 in), first
Nperform undercut (3) and then
cross-cut at a distance of about
20 cm/8 in (A) from the final cut.
Then carry out the flush-cut (4),
starting with a relieving cut and
finishing with a cross-cut.

Cutting above obstacles
The machine's long reach makes it
possible to prune branches that are
overhanging obstacles, such as rivers or
lakes. The tool angle in this case
depends on the position of the branch.
Cutting from a lift bucket
The machine's long reach enables
cutting to be performed next to the trunk
without the risk of the lift bucket
damaging other branches. The tool
angle in this case depends on the
position of the branch.
A cutting attachment consists of the saw
chain, guide bar and chain sprocket.
The cutting attachment that comes
standard is designed to exactly match
the pole pruner.
–The pitch (t) of the saw chain (1),
chain sprocket and the nose
sprocket of the Rollomatic guide bar
must match.
–The drive link gauge (2) of the saw
chain (1) must match the groove
width of the guide bar (3).
If non-matching components are used,
the cutting attachment may be damaged
beyond repair after a short period of
operation.
Chain scabbard
Your pole pruner comes standard with a
chain scabbard that matches the cutting
attachment.
If you use guide bars of different lenghts
on the pole pruner, the length of the
chain scabbard must be matched to the
guide bar to reduce the risk of injury. It
should cover the full length of the guide
bar.
The length of the matching guide bars is
marked on the side of the chain
scabbard.
