GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instruc-
tions. Failure to follow the warnings and
instructions may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future
reference.The term “power tool” in the warnings
refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
Do not operate power tools in explosive at-
mospheres, such as in the presence of flam-
mable liquids, gases or dust. Power tools cre-
ate sparks which may ignite the dust or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
If operating a power tool in a damp location
is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a
GFCI reduces the risk of electric shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use a power tool while you are
tired or under the influence of drugs, alcohol
or medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before connect-
ing to power source and/or battery pack,
picking up or carrying the tool. Carrying power
tools with your finger on the switch or energis-
ing power tools that have the switch on invites
accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
If devices are provided for the connection of
dust extraction and collection facilities, en-
sure these are connected and properly used.
Use of dust collection can reduce dust-related
hazards.

GENERAL POWER TOOL SAFETY WARNINGS
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that can-
not be controlled with the switch is dangerous
and must be repaired.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are dan-
gerous in the hands of untrained users.
Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage of
parts and any other condition that may affect
the power tool’s operation. If damaged, have
the power tool repaired before use. Many ac-
cidents are caused by poorly maintained power
tools.
Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
BATTERY TOOL USE AND CARE
Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of
fire when used with another battery pack.
Use power tools only with specifically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fire.
When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small
metal objects, that can make a connection
from one terminal to another. Shorting the
battery terminals together may cause burns or
a fire.
Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with wa-
ter. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery
may cause irritation or burns.
SERVICE
Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts. This will ensure that the safety of
the power tool is maintained.
When servicing a power tool, use only iden-
tical replacement parts. Follow instructions
in the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
shock or injury.

PRUNING SAW SAFETY WARNINGS
Keep all parts of the body away from the
pruner when the pruner is operating. Before
you start the pruner, make sure the saw
chain is not contacting anything. A moment
of inattention while operating pruners can cause
entanglement of your clothing or body with the
saw chain.
Always hold the pruner with your right hand
on the rear handle and your left hand on the
front handle. Holding the pruner with a reversed
hand configuration increases the risk of personal
injury and should never be done.
Hold the power tool by insulated gripping
surfaces only, because the saw chain may
contact hidden wiring. Saw chains contacting
a “live” wire may make exposed metal parts of
the power tool “live” and could give the operator
an electric shock.
NOTE: For pruners designed with the GUIDE
BAR on the left side, the reference to “right
hand”and “″left hand”″ positioning is reversed.
Wear safety glasses and hearing protec-
tion. Further protective equipment for head,
hands, legs and feet is recommended.
Adequate protective clothing will reduce per-
sonal injury by flying debris or accidental contact
with the saw chain.
Do not operate a pruner in a tree. Operation of
a pruner while up in a tree can result in personal
injury.
Always keep proper footing and operate the
pruner only when standing on fixed, secure
and level surface. Slippery or unstable surfaces
such as ladders may cause a loss of balance or
control of the pruner.
When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood fibres is released the spring loaded limb
may strike the operator and/or throw the pruner
out of control.
Use extreme caution when cutting brush and
saplings. The slender material may catch the
pruner chain and be whipped toward you or pull
you off balance.
Carry the pruner by the front handle with
the pruner switched off and away from
your body. When transporting or storing the
pruner always fit the guide bar cover. Proper
handling of the chain saw will reduce the likeli-
hood of accidental contact with the moving saw
chain.
Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensioned or lubricated chain could break the
pruner chain.
Keep handles dry, clean, and free from oil
and grease. Greasy, oily handles are slippery
causing loss of control.
Cut wood only. Do not use pruner for pur-
poses not intended. For example: do not use
pruner for cutting plastic, masonry or non-
wood building materials. Use of the pruner for
operations different than intended could result
in a hazardous situation.
Maintain a firm grip, with thumbs and fingers
encircling the pruner handles, with both
hands on the pruner. Maintaining control of
the pruner will reduce the risk of losing control.
Do not let go of the pruner.
Do not overreach and do not cut above chest
height. This helps prevent unintended tip con-
tact and enables better control of the chain saw
in unexpected situations.
Only use replacement bars and chains speci-
fied by the manufacturer. Incorrect replace-
ment bars and chains can cause chain breakage
and increase the risk of injury.
Follow the manufacturer’s sharpening and
maintenance instructions for the pruner
chain. Decreasing the depth gauge height can
lead to increased risk of injury.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.

5 – English
PRUNING SAW SAFETY WARNINGS
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and back
towards the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards
the operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw. As a chain saw
user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
Do not start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree. Cluttered areas invite ac-
cidents.
Keep ALL children, bystanders, visitors, and
animals out of the work area while starting or
cutting with the chain saw. Do not let visitors
contact chain saw or extension cord.
Do not operate chain saw in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Chain saws create
sparks which may ignite the dust or fumes.
Dress Properly – Wear snug fitting clothing.
Always wear heavy, long pants, long sleeves,
overalls, jeans or chaps made of cut resistant
material or ones that contain cut resistant
inserts. Wear non-slip safety footwear. Wear
non-slip heavy duty gloves to improve your
grip and to protect your hands. Do not wear
jewellery, short pants, sandals, or go barefoot.
Do not wear loose fitting clothing, which could
be drawn into the motor or catch the chain or
underbrush. Secure hair so it is above shoulder
level. Wear hearing and head protection.
Heavy protective clothing may increase operator
fatigue, which could lead to heat stroke. Dur-
ing weather that is hot and humid, heavy work
should be scheduled for early morning or late
afternoon hours when temperatures are cooler.
Always wear eye protection with side shields
marked to comply with ANSI Z87.1 as well as
hearing and head protection when operating
this equipment.
Always be aware of what you are doing when
using the chain saw. Use common sense. Do
not operate the chain saw when you are tired, ill,
upset, or under the influence of alcohol, drugs,
or medication.
Do not expose the chain saw to rain.
Do not use the chain saw in damp or wet
locations.
Stay alert and pay attention to what you are do-
ing. Use common sense when using this unit.
Keep all parts of your body away from the saw
chain when the unit is running.
Never let anyone use your chain saw who has
not received adequate instructions in its proper
use. This applies to rentals as well as privately
owned saws.
Before you start the unit, make sure the saw
chain is not contacting any object.
Stop the chain saw before setting it down.
To avoid accidental starting, never carry the unit
with your finger on the switch trigger.
Maintain the unit with care. Keep the cutting
edge sharp and clean for best performance and
to reduce the risk of injury. Follow instructions
for lubricating and changing accessories.
Do not operate a chain saw with one hand! Use
a firm grip with thumbs and fingers encircling the
chain saw handles. Serious injury to the opera-
tor, helpers, bystanders, or any combination of
these persons may result from one-handed op-
eration. A chain saw is intended for two-handed
use.
Guard against electric shock – Avoid body con-
tact with grounded surfaces such as metal pipes
and wire fences. There is an increased risk of
electric shock if your body is grounded.
Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and

6 – English
PRUNING SAW SAFETY WARNINGS
securely assembled. Chain should slow to a
stop when the switch trigger is released. If the
chain continues to turn after the switch trigger
has been released, have the unit serviced by an
authorized service center.
Check for damaged parts. Check for alignment
of moving parts, binding of moving parts, break-
age of parts, mounting, and any other condi-
tions that may affect its operation. A guard or
other part that is damaged should be properly
repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in
this manual.
All chain saw service, other than the items listed
in the operation and maintenance sections,
should be performed by an authorized service
center.
Always maintain a proper stance.
Do not use chain saw if switch does not turn it on
and off. Have switch replaced by an authorized
service center.
Do not adapt your power head to a bow guide
or use it to power any attachments or devices
not listed for the saw.
Disconnect chain saw from power supply when
not in use, before servicing, and when making
adjustments and changing attachments, such
as saw chain and guard.
Do not cut vines and/or small underbrush.
Do not operate a chain saw in a tree, on a ladder,
rooftop, scaffold, or other unstable support; this
is extremely dangerous.
NOTE: The size of the work area depends on the
job being performed as well as the size tree or
work piece involved. For example, felling a tree
requires a larger work area than making bucking
cuts.
Do not force the chain saw. The job can be per-
formed better and safer at the rate for which it
was intended.
Always use the right product for your applica-
tion. The chain saw should be used for cutting
wood only. Never use the chain saw to cut plas-
tic, masonry or non-wood building materials.
Store chain saw when not charging or when not
in use. Chain saw should be stored in a dry and
high or locked area out of the reach of children.
When storing chain saw place the scabbard on
the bar and chain.
Use this product only with batteries and char-
gers listed in tool/appliance/battery pack/char-
ger correlation supplement 995000850.
Battery operated units do not have to be
plugged into an electrical outlet; therefore, they
are always in operating condition. Be aware
of possible hazards even when unit is not
operating.
Remove the battery pack from the chain saw
when not charging and before cleaning, servic-
ing, storing, removing material from the unit,
changing accessories such as the bar and
chain, or when not in use.
Never use water or any liquids to clean or rinse
off your product and do not expose the product
to rain or wet conditions. Store indoors in a dry
area. Corrosive liquids, water, and chemicals
can enter the product’s electronic components
and/or battery compartment and damage elec-
tronic components and/or the battery pack,
which can result in a short circuit, increased risk
of fire, and serious personal injury. Remove any
buildup of dirt and debris by wiping the product
clean with a dry cloth occasionally.
Keep safety tip anti-kickback nose guard
properly mounted on the guide bar to prevent
rotational kickback.

PRUNING SAW SAFETY WARNINGS
KICKBACK
See Figures 1 - 3.
WARNING
Kickback may occur when the moving chain
contacts an object at the upper portion of the
tip of the guide bar or when the wood closes in
and pinches the saw chain in the cut. Contact
at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and
stop the chain for an instant. The result is a
lightning fast, reverse reaction which kicks
the guide bar up and back toward the opera-
tor. If the saw chain is pinched along the top
of the guide bar, the guide bar can be driven
rapidly back toward the operator. Either of
these reactions can cause loss of saw control
which can result in serious injury. Do not rely
exclusively upon the safety devices built into
the saw. As a chain saw user, you should take
several steps to keep your cutting jobs free
from accident or injury.
The following precautions should be followed
to minimize kickback:
• Always grip the saw firmly with both hands.
Hold the saw firmly with both hands when
the unit is running. Place your right hand on
the rear handle and your left hand on the
front handle with your thumbs and fingers
encircling the chain saw handles. A firm grip
together with a stiff left arm will help you main-
tain control of the saw if kickback occurs.
• Make sure that the area in which you are cut-
ting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch,
fence, or any other obstruction that could be
hit while you are operating the saw.
• Always cut with the unit running at full speed.
Fully squeeze the throttle trigger and maintain
a steady cutting speed.
• Use replacement parts such as low kickback
chain and special guide bars that reduce the
risks associated with rotational kickback. Use
only the replacement guide bars and low kick-
back chains specified by the manufacturer for
the saw.
With a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
Do not overreach. Keep proper footing and bal-
ance at all times.
Do not cut above chest height or overreach
when cutting. Do not let the nose of the guide
bar contact a log, branch, ground, or any other
obstruction while you are operating the unit.

PRUNING SAW SAFETY WARNINGS
Follow the sharpening and maintenance instruc-
tions for the saw chain.
Push and Pull – This reaction force is always
opposite to the direction the chain is moving
where wood contact is made. Thus, the operator
must be ready to control the PULL when cutting
on the bottom edge of the bar, and PUSH when
cutting along the top edge. See Figure 3.
UNDERSTANDING YOUR CHAIN SAW SAFETY
DEVICES
LOW KICKBACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter
can minimize the force of a kickback reaction by
preventing the cutters from digging in too deeply
at the kickback zone. Only use replacement chain
that is equivalent to original chain or has been
certified as low kickback chain per ANSI B175.1.
Low kickback saw chain is chain that has met
the kickback performance requirements of ANSI
B175.1 (American National Standard for Power
Tools – Gasoline-Powered Chain Saws-Safety
Requirements) when tested on the representative
sample of chain saws below 3.8 c.i.d. specified in
ANSI B175.1.
As saw chains are sharpened during their useful
life, they lose some of the low kickback qualities
and extra caution should be used.
GUIDE BARS
Generally, guide bars with small radius tips have
somewhat lower kickback potentials.
When making a replacement, be sure to order
one of the bars listed for the saw in this operator’s
manual.
Save these instructions. Refer to them frequent-
ly and use them to instruct others who may use
this product. If you loan someone this product,

PREPARATION FOR CUTTING
PROPER GRIP ON HANDLES
See Figures 9 - 11.
Refer to Important Safety Instructions earlier in this
manual for appropriate safety equipment.
Wear non-slip gloves for maximum grip and
protection.
Hold the saw firmly with both hands. Always
keep your left hand on the front handle and your
right hand on the rear handle so that your body
is to the left of the chain line.
WARNING:
Never use a left-handed (cross-handed) grip,
or any stance which would place your body
or arm across the chain line. Improper opera-
tion of the chain saw could result in serious
personal injury.
Maintain a proper grip on the saw whenever
the unit is running. The fingers should encircle
the handle and the thumb is wrapped under the
handlebar. This grip is least likely to be broken
(by a kickback or other sudden reaction of the
saw). Any grip in which the thumb and fingers
are on the same side of the handle, is danger-
ous because a slight kick of the saw can cause
loss of control.
WARNING:
Do not operate the switch trigger with your
left hand and hold the front handle with your
right hand. Never allow any part of your body
to be in the chain line while operating a saw.
Improper operation of the chain saw could
result in serious personal injury.

PROPER CUTTING STANCE
See Figure 12.
WARNING:
Always use the proper cutting stance de-
scribed in this section. Never kneel when us-
ing the chain saw. Kneeling could result in loss
of stability and control of the saw resulting in
serious personal injury.
Weight should be balanced with both feet on
solid ground.
Keep left arm with elbow locked in a “straight
arm” position to withstand any kickback force.
Your body should always be to the left of the
chain line.
Thumb should be on underside of handlebar.
BASIC CUTTING PROCEDURE
Practice cutting a few small logs using the follow-
ing technique to get the “feel” of using the saw
before you begin a major sawing operation.
Support log on a saw horse or cradle.
Take the proper stance in front of the wood with
the saw off.
Squeeze the switch trigger and let the chain
accelerate to full speed before entering the cut.
Begin cutting with the saw against the log.
Keep the unit running the entire time you are
cutting, maintain a steady speed.
Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, dam-
age to the bar, chain, or unit can result.
Release the switch trigger as soon as the cut
is completed, allowing the chain to stop. If you
run the saw without a cutting load, unnecessary
wear can occur to the chain, bar, and unit.
Do not put pressure on the saw at the end of
cut.
WORK AREA PRECAUTIONS
Cut only wood or materials made from wood,
no sheet metal, no plastics, no masonry, no
non-wood building materials.
Never allow children to operate the saw. Allow
no person to use this chain saw who has not
read this Operator’s Manual or received ad-
equate instructions for the safe and proper use
of this chain saw.
Keep everyone - helpers, bystanders, children,
and animals - a safe distance from the cutting
area. During felling operations, the safe dis-
tance should be a least twice the height of the
largest trees in the felling area. During bucking
operations, keep a minimum distance of 15 feet
between workers.
Always cut with both feet on solid ground to
prevent being pulled off balance.
Do not cut above chest height, as a saw held
higher is difficult to control against kickback
forces.
Do not fell trees near electrical wires or build-
ings. Leave this operation for professionals.
Cut only when visibility and light are adequate
for you to see clearly.
LIMBING
See Figure 13.
WARNING:
Never climb into a tree to limb or prune. Do
not stand on ladders, platforms, a log, or in
any position which can cause you to lose your
balance or control of the saw, which could
result in death or other serious personal injury.
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the chain
saw with a firm grip. Always make sure your
footing is secure and your weight is distributed
evenly on both feet.
Leave the larger support limbs under the tree to
keep the tree off the ground while cutting.

18 – English
Limbs should be cut one at a time. Remove the
cut limbs from the work area often to help keep
the work area clean and safe.
Branches under tension should be cut from the
bottom up to avoid binding the chain saw.
Keep the tree between you and the chain saw
while limbing. Cut from the side of the tree op-
posite the branch you are cutting.
PRUNING
See Figure 14.
Pruning is trimming limbs from a live tree.
Work slowly, keeping both hands on the chain
saw with a firm grip. Always make sure your
footing is secure and your weight is distributed
evenly on both feet.
Do not cut from a ladder, this is extremely dan-
gerous. Leave this operation for professionals.
Do not cut above chest height as a saw held
higher is difficult to control against kickback.
When pruning trees it is important not to make
the finishing cut next to the main limb or trunk
until you have cut off the limb further out to
reduce the weight. This prevents stripping the
bark from the main member.
Underbuck the branch 1/3 through for your first
cut.
Your second cut should overbuck to drop the
branch off.
Now make your finishing cut smoothly and
neatly against the main member so the bark will
grow back to seal the wound.
WARNING:
If the limbs to be pruned are above chest
height, hire a professional to perform the prun-
ing. Failure to do so could result in death or
serious personal injury.
SPRINGPOLES
See Figure 15.
A springpole is any log, branch, rooted stump, or
sapling which is bent under tension by other wood
so that it springs back if the wood holding it is cut
OPERATION
SPRINGPOLE
or removed. On a fallen tree, a rooted stump has
a high potential of springing back to the upright
position during the bucking cut to separate the log
from the stump. Watch out for springpoles, they
are dangerous.
WARNING:
Springpoles are dangerous and could strike
the operator, causing the operator to lose
control of the chain saw. This could result in
severe or fatal injury to the operator.
