STIHL recommends the use of STIHL
original tools, guide bars, saw chains,
sprockets and accessories. The
characteristics of these components are
specifically designed to match your
machine and meet your performance
requirements.
Use only extension cords of the
approved type. Unsuitable extension
cords may be dangerous.
Make sure that conductor cross section
(wire gauge) of the extension cord
meets the minimum requirements (see
chapter on “Starting”).
Clothing and Equipment
Wear proper protective clothing and
equipment.
Clothing must be sturdy
but allow complete
freedom of movement.
Wear snug-fitting clothing
with cut retardant
inserts – an overall and
jacket combination, do not
wear a work coat.
Avoid loose-fitting jackets, scarves,
neckties, jewellery or anything that could
get caught on wood or brush. Tie up and
confine long hair (e.g. with a hair net,
cap, hard hat, etc.).
Wear steel-toed safety
boots with cut-retardant
inserts and non-slip soles.
Wear a safety hard hat
where there is a danger of
head injuries from falling
objects. Wear safety
glasses.
Wear and hearing protection, e.g.

Before Starting
– Check that your power tool is
properly assembled and in good
condition – refer to appropriate
chapters in the instruction
mCorrectly mounted guide bar.
– Correctly tensioned chain.
– Never attempt to modify the controls
or safety devices.
– Keep the handles dry and clean,
free from oil and pitch, for safe
control.
The voltage and frequency of your oiwer
supply and the voltage and frequency
specified on the machine (see rating
plate) must be the same.
The wall outlet must be equipped with a
ground fault circuit interrupter or such a
device must be installed in the circuit
when operating the electric pole pruner.
Contact your local electrician for more
information.
It is important to inspect the power
supply cord, plug, switch and extension
cord. Never use damaged cords,
couplings or plugs. Use only approved
extension cords.
If the power cord is
damaged or cut,
immediately disconnect
the plug from the power
supply to reduce the risk
of electrocution.
The couplings of extension cords must
be splash-proof.
To avoid the risk of accidents and
personal injury, do not operate your unit
if it is not in a safe operating condition.
Holding and Controlling the Unit
Always hold the unit firmly with both
hands. Put your right hand on the
handle housing, left hand on the drive
tube. Left handers should follow these
instructions too.

During Operation
In the event of imminent danger or in an
emergency, switch off the motor
immediately and disconnect the plug
from the power supply.
Your machine is designed to be
operated by one person only. Do not
allow other persons in the work area –
even when switching on.
To reduce the risk of damage, be sure
that the guide bar and chain are clear of
all obstructions and objects, including
the ground, before switching on.
Warning!
This power tool is not
insulated. To avoid the
risk of electrocution,
maintain a minimum
clearance of 15 m (50ft)
from electric power lines.
To reduce the risk of injuries from falling
objects and thrown pieces of wood,
always keep bystanders at least 15 m
(50 ft) away from your own position.
To reduce the risk of damage to
property, also maintain this distance
from other objects (vehicles, windows).
Maintain a minimum clearance of 15 m
(50 ft) between the bar nose and electric
power lines. Electricity can jump
considerable distances by means of
arcing. Higher voltage increases the
distance electricity can arc. Before
working with less clearance, contact
your electric utility and make sure
current is turned off.
Use your electric pole pruner only for the
purposes described in the instruction
manual.
The drive motor is not
waterproof. To reduce
the risk of electrocution
and short circuit, never
use the electric pole
pruner in the rain or in wet
or very damp conditions.
Do not leave the pole pruner outdoors in
the rain.
Never jerk the power cord to disconnect
the plug from the wall outlet. To unplug,
grasp the plug, not the cord.
Always unwind the extension cord
completely from the cable drum to
reduce the risk of fire from overheating.
Take special care in slippery conditions
– damp, snow, ice, on slopes, uneven
ground, etc.
Watch out for obstacles: Roots, tree
stumps or holes which could cause you
to trip or stumble.
Make sure you always have firm and
secure footing.

When working at a height that exceeds
the unit’s reach use a lift bucket.
Never work on a ladder, in a tree or on
any other insecure support. Never
attempt to operate your pole pruner with
one hand.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
To reduce the risk of accidents, take a
break in good time to avoid tiredness or
exhaustion.
Work calmly and carefully – in daylight
conditions and only when visibility is
good – ensure you do not endanger
others – stay alert at all times.
The dust that occurs during operation of
this machine (wood dust) may be
harmful to health. If dust levels are very
high, wear a suitable respirator.
If your power 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 – see also
“Before Starting”.
Check in particular that the safety
devices are working properly. Do not
continue operating your power tool if it is
damaged. In case of doubt, have the
machine checked by your servicing
dealer.
Limbing
Hold the pole pruner at an angle of not
more than 60° from the horizontal. Do
not stand directly underneath the limb
being cut. Watch for falling wood.
Keep the work area clear – remove
interfering limbs and brush.
Before limbing, establish a path of
escape and remove all obstacles.

Position the cutting attachment with the
hook against the branch and then
perform the cross-cut. This reduces the
risk of the pruner being jerked forward
as you start the cross-cut.
Always start the cut with the chain
running.
Work only with a properly sharpened
and tensioned chain – the depth gauge
setting should not be too wide.
Perform cross-cut from the top
downward to avoid the chain pinching in
the cut.
If branch is thick or heavy, make a
relieving cut (see chapter on ”Using the
Pole Pruner”).
To reduce the risk of injury, take special
care when cutting branches under
tension.
Always make a relieving cut on the
compression side first and then perform
the bucking cut at the tension side. This
helps avoid the saw chain pinching in
the cut.
Take special care when cutting
shattered wood – sharp slivers of wood
may be caught and flung in your
direction.
If on a slope, stand on the uphill side or
to one side of the branch to be cut.
Watch out for rolling branches.
When you come to the end of a cut, note
that the unit is no longer supported by
the guide bar in the cut. Hold the unit
firmly to take its weight at the end of the
cut and avoid loss of control.
Always pull the unit out of the cut with
the chain running.
To avoid the risk of accidents, use your
pole pruner for limbing and pruning only.
It is not designed for felling.
Make sure your saw chain does not
touch any foreign materials:
Stones, nails, etc. may be flung off and
damage the saw chain.
Position the power cord so that it cannot
be damaged and does not endanger
anyone. If the power cord is twisted:
Disconnect the plug from the power
supply and straighten out the cord.
Position the power cord so that it cannot
come into contact with the rotating
chain.
Make sure the power cord does not
chafe on edges, pointed or sharp
objects. Do not squeeze the power cord
through narrow gaps in doors or
windows.
Before carrying the unit a short distance,
e.g. to next cutting site: Switch off the
motor (release the switch).
Before leaving the electric pole pruner
unattended: switch off the motor and
disconnect the plug from the power
supply.

Vibrations
Prolonged use of the unit may result in
vibration-induced circulation problems in
the hands (whitefinger disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
– Hand protection (wearing warm
gloves)
– Operation with frequent breaks
The period of usage is shortened by:
– Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, tingling
sensation)
– Low outside temperatures
– Gripping force (a tight grip hinders
circulation)
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and Repairs
To reduce the risk of injury from
unintentional chain rotation, always
disconnect the plug from the power
supply before carrying out any
maintenance work on the machine.
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and receive technical
information bulletins on engineering
changes.
Use only high quality replacement parts
since there is otherwise a risk of
accidents or damage to the machine. If
you have any questions in this respect,
consult a servicing dealer.
STIHL recommends you use only
original STlHL replacement parts. The
characteristics of these parts are
specifically designed to match your
machine model and meet your
performance requirements.
Electrical components, e.g. power cord,
may only be repaired or replaced by a
qualified electrician.
Observe sharpening instructions
for safe and correct handling of saw
chain and guide bar.
Keep the chain in good condition at all
times. It must be properly sharpened,
tensioned and well lubricated.

Preparations
:Wear suitable protective clothing
and equipment – see "Safety
Precautions".
:Put on the shoulder strap.
Never throw cuttings into the
household garbage can – cuttings
can be composted.
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.
Cutting sequence
To allow branches a free fall, always cut
the lower branches first. Prune heavy
branches (large diameter) in several
controllable pieces.
Working position
Hold the handle housing with your right
hand, and the drive tube with your left
hand. Your left arm should be extended
to the most comfortable position.
The drive tube should always be held at
an angle of 60° or less.
The most convenient working position is
a tool angle of 60°, but any lesser angle
may be used to suit the situation
concerned.
Cross-cut
To avoid pinching the bar in the cut,
position the cutting attachment with the
hook 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.
:To do this, apply the cutting
attachment and pull it across the
bottom of the branch as far as the
bar nose.
:Locate the hook against the branch
and then perform the cross-cut (2)
from the top downwards.
Flush-cutting thick branches
:If branch diameter is more than
10 cm, first perform undercut (3)
and then cross-cut at a distance of
about 20 cm (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 unit'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 unit'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 depends on
the position of the branch.
30° angle drive
(special accessory)
The angle drive keeps the cutting
attachment at an angle of 30° to the
drive tube.
The angle drive may be adjusted on the

For automatic and reliable
lubrication of the chain and guide
bar: Use only a quality,
environmentally compatible
chain and bar lubricant. STIHL
chain lubricant with non-fling
additive or the rapidly
biodegradable STIHL BioPlus is
recommended.
Biological chain oil must be resistant
to aging (e.g. STIHL BioPlus) since
it will otherwise quickly turn to resin.
This results in hard deposits that are
difficult to remove, especially in the
area of the chain drive and chain. It
may even cause the oil pump to
seize.
The service life of the chain and guide
bar depends on the quality of the
lubricant. It is therefore essential to use
only a specially formulated chain
lubricant!
If special chain lubricant is not available,
you may – in an emergency – use an HD
single grade or multigrade engine oil
with a viscosity that suits the prevailing
outside temperature.
Do not use waste oil!
Medical studies have shown that
renewed contact with waste oil can
cause skin cancer. It also harms the
environment!
Waste oil does not have the
required lubricating properties and
is unsuitable for chain lubrication.
Check the oil level regularly during
cutting work. Never allow the oil tank
to run dry.
The gearbox becomes hot during
operation. To avoid the risk of burn
injuries, do not touch the gear
housing.
:Thoroughly clean the filler cap and
area around it so that no dirt can fall
into the tank.
:Position the unit so that the filler cap
faces up.
If the oil level in the tank does not go
down, the reason may be a problem in
the oil supply system: Check chain
lubrication, clean the oilways, contact
your servicing dealer for assistance if
necessary. STIHL recommends that you
have maintenance and repair work
performed only by a STIHL servicing
dealer.

The bayonet-type oil tank filler cap with
its hinged clip can be opened and closed
without tools.
:To open the tank, swing the clip (1)
to the vertical position.
:Turn the filler cap counterclockwise
as far as stop and remove.
:Fill up with chain oil.
:To close the oil tank, place the filler
cap in position with the clip vertical,
making sure the recesses (2) are in
alignment.
:Turn the filler cap clockwise as far
as stop.
:Fold the clip down so that it is flush
with the top of the cap.
The saw chain must always throw off a
small amount of oil.
:Always check chain lubrication and
the oil level in the tank before
starting work.
Never operate your pruner without
chain lubrication. If the chain is run
dry, the whole cutting attachment
will be irretrievably damaged within
a very short time.
Inadequate lubrication can be caused by
a dirty oil strainer: Have the oil strainer
cleaned or replaced by your servicing
dealer.
Every new chain has to be broken in
for about 2 to 3 minutes.
After breaking in the chain, check
chain tension and adjust if
necessary – see chapter
"Checking Chain Tension".

The unit is equipped with an overload
circuit breaker which cuts off the power
supply in the event of mechanical
overload due to, e.g.
– excessive infeed force
– “lugging down” the motor
– pinching the saw chain in the cut.
If the overload circuit breaker has cut off
the power supply:
:Pull the guide bar out of the cut.
:Wait about 3 minutes for the
overload circuit breaker to cool
down.
Do not switch on the unit during this
period because you will otherwise
prolong the required cooling time.
Once the motor starts:
:Run the unit for about 15 seconds
off load. This helps cool the motor
windings and considerably delays
renewed tripping of the overload
circuit breaker.
During operation
Check chain tension frequently.
A new chain has to be tensioned more
often than one that has been in use for
some time.
Cold chain:
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand.
Retension if necessary – see chapter on
“Tensioning the Saw Chain”.
Chain at operating temperature:
The chain stretches and begins to sag.
The drive links on the underside of the
bar must not come out of the bar groove
– the chain may otherwise jump off the
bar.
Retension the chain – see chapter on
“Tensioning the Saw Chain”.
Always slacken off the chain again
after finishing work. The chain
contracts as it cools down. If it is not
slackened off, it may damage the
gear shaft and bearings.
After finishing work
:Slacken off the chain if you have
retensioned it at operating
temperature during cutting work.
The chain contracts as it cools
down. If it is not slackened off, it may
damage the gear shaft and
bearings.
Storing machine for a short period:
Store the machine in a dry place until
you need it again.
Storing for longer period:
See chapter "Storing the Machine".

:Remove the chain sprocket cover,
chain and guide bar.
Replace the chain sprocket:
– after using two Oilomatic chains or
sooner
– if the wear marks (dimension a) on
the sprocket are deeper than
0.5 mm – the life of the chain would
otherwise be reduced. Use
reference gauge (special
accessory) to check the depth of the
wear marks.
The service life of the chain
sprocket is prolonged if it is used
with two chains in rotation.
Use only original STIHL replacement
sprockets.
:Use a screwdriver to remove the
E-clip (1).
:Pull the washer (2)and sprocket (3)
off the gear shaft.
:Clean the stub of the gear shaft and
lubricate it with STIHL lubricating
grease (special accessory).
:Fit the new chain sprocket on the
gear shaft.
:Fit the washer and E-clip on the
gear shaft.
Correctly sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
Do not work with a dull or damaged saw
chain as it will increase the physical
effort required, cause higher vibrations,
produce unsatisfactory results and a
higher rate of wear.
:Clean the chain.
:Check the chain for cracks in the
links and damaged rivets.
:Replace any damaged or worn parts
of the chain and match the new
parts to the shape and size of the
original parts by filing back as
necessary.
It is necessary to comply with the
angles and dimensions specified
below. If the saw chain is
incorrectly sharpened – especially
if the depth gauges are too low –
there is an increased risk of
kickback and resulting injury!
