ated (cordless) power tool.
tions, illustrations and specica-
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create 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. Unmodied 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 electric
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 exten-
sion cord suitable for outdoor use. Use of a cord suit-
able 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 an 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 inuence 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 a 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 o-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your nger on the
switch or energizing 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 ro-
tating 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
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry or long hair can
be caught in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 o. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/
or remove the battery pack, if detachable, 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. Pow-
er tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may aect
the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly
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
dierent from those intended could result in a hazardous
situation.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used
with another battery pack.
• Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
• 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 re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact accidentally occurs, ush with water. If liquid contacts

eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or
modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or
risk of injury.
• Do not expose a battery pack or tool to re or exces-
sive temperature. Exposure to re or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging im-
properly or at temperatures outside the specied range
may damage the battery and increase the risk of re.
SERVICE
• Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
HATCHET PRUNING SAW
General pruning saw safety warnings:
• Keep all parts of the body away from the saw chain
when the pruning saw is operating. Before you
start the pruning saw, make sure the saw chain
is not contacting anything. A moment of inattention
while operating pruning saws may cause entangle-
ment of your clothing or body with the saw chain.
• Hold the pruning saw with your right hand on the
trigger handle and your left hand on the body
grip. Holding the pruning saw with a reversed hand
conguration increases the risk of personal injury.
• Hold the pruning saw 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 pruning saw
"live" and could give the operator an electric shock.
• Wear eye protection. Further protective equipment
for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce
personal injury from ying debris or accidental contact
with the saw chain.
• Always keep proper footing and operate the prun-
ing saw only when standing on xed, secure and
level surface. Slippery or unstable surfaces may
cause a loss of balance or control of the pruning saw.
• Do not operate a pruning saw in a tree, on a lad-
der, rooftop, or scaold unless properly trained.
To avoid death or serious injury, operator must be
trained in safe climbing techniques and in the use of
all appropriate safety equipment.
• When cutting a limb that is under tension be alert
for spring back. When the tension in the wood bres
is released the spring loaded limb may strike the
operator and/or throw the pruning saw out of control.
• Use extreme caution when cutting brush and sap-
lings. The slender material may catch the saw chain
and be whipped toward you or pull you o balance.
• Carry the pruning saw away from your body and
with your nger o of the trigger. When transporting or storing the pruning saw always t the
scabbard. Proper handling of the pruning saw will
reduce the likelihood of accidental contact with the
moving saw chain.
• Follow instructions for lubricating, chain tensioning and changing the bar and chain. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
• Cut wood only. Do not use pruning saw for purposes not intended. For example: do not use
pruning saw for cutting metal, plastic, masonry
or non-wood building materials. Use of the pruning
saw for operations dierent than intended could result
in a hazardous situation.
• Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid
them. Serious injury could occur to the operator or
bystanders while felling a tree.
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.
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 pruning saw user, you should
take several steps to keep your cutting jobs free from
accident or injury.
Kickback is the result of pruning saw misuse and/or in-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• Maintain a rm grip on the pruning saw and position your body and arm(s) to allow you to resist
kickback forces. Kickback forces can be controlled
by the operator, if proper precautions are taken. Do
not let go of the pruning saw.
• Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact
and enables better control of the pruning saw in
unexpected situations.
• Make sure that the area in which you are cutting
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.
• Only use replacement guide bars and saw chains
specied by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain
breakage and/or kickback.
• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreas-
ing the depth gauge height can lead to increased
kickback.
• Follow all instructions when clearing jammed
material, storing or servicing the pruning saw.
Make sure the switch is o and the battery pack
is removed. Unexpected actuation of the pruning
saw while clearing jammed material or servicing may
result in serious personal injury.
Other Pruning Saw Safety Rules
• Do not start cutting until you have a clear work area,
secure footing, and a planned retreat path from the
falling workpiece. Cluttered areas invite accidents.
• Keep ALL children, bystanders, visitors, and ani-
mals out of the work area while starting or cutting
with the pruning saw.

under the inuence of alcohol, drugs, or medication.
• Keep all parts of your body away from the saw
chain when the unit is running.
• Never let anyone use your pruning 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 pruning saw before setting it down.
• 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.
• Maintain a rm grip on the recommended grasp-
ing surfaces. If an operation cannot be performed
safely with two hands on the saw, USE EXTREME
CAUTION.
• During operations where it is necessary to use
one hand, such as to steady or control the work-
piece/branch, guide workpiece away from you, or
provide better visibility to the work area:
• Keep free hand clear of the chain and out of the
cutting path.
• Maintain a rm grip on the branch being cut to avoid
"skating" or "bouncing" of the saw.
• Never cut above shoulder height.
• Do not cross arms or overreach.
• Always cut away from yourself.
• Avoid excess exing or tension on the branch be-
ing cut.
• Do not operate a pruning saw that is damaged, improperly adjusted, or not completely and 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.
• Do not force the pruning saw. The job can be
performed better and safer at the rate for which it
was intended.
• Always use the right product for your application.
The pruning saw should be used for cutting wood only.
Never use the pruning saw to cut plastic, masonry or
non-wood building materials.
• Use extreme caution when cutting thin branches,
vines or small underbrush. The slender material
may catch the saw chain and be whipped toward you
or pull you o balance. We recommend using hedge
trimmers or brush cutters for these operations.
• Store pruning saw when not in use. Pruning saw
should be stored in a dry and high or locked area out
of the reach of children. When storing pruning saw
place the cover on the bar and chain.
• Battery operated units do not have to be plugged
into an electrical outlet; therefore, they are always
in operating condition. Be aware of possible haz-
ards even when unit is not operating.
• Save these instructions. Refer to them frequently
and use them to instruct others who may use this
product. If you loan someone this product, loan them

• 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.

Position
Practice cutting a few small logs using the following
technique to get the “feel” of using the saw before
you begin a major sawing operation.
• Take the proper stance in front of the wood with
the saw o.
• Squeeze the switch trigger and let the chain acceler-
ate 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 down-
ward pressure. If you force the cut, damage 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.
• 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 pruning saw who has not read this
Operator’s Manual or received adequate instructions
for the safe and proper use of this pruning saw.
• Do not attempt to fell a tree or sapling greater than
3" (76 mm) in diameter. To avoid death or serious
injury, operator must be trained in safe tree felling
techniques, in the use of all appropriate safety
equipment and use of a pruing saw suitable for the
application.
• Always cut with both feet on solid surface to prevent
being pulled o balance.
• Do not cut above shoulder height, as a saw held
higher is dicult to control against kickback forces.
• Do not fell trees near electrical wires or buildings.
Leave this operation for professionals.
• Cut only when visibility and light are adequate for
you to see clearly.
• Check work area for hazards such as bees, rodents,

snakes, etc., that may live in trees or brush.
Bucking is the term used for cutting a fallen tree to
the desired log length.
• Always make sure your footing is secure and your
weight is distributed evenly on both feet.
• Cut only one log at a time.
• Support small logs on a saw horse or another log
while bucking.
• Keep a clear cutting area. Make sure that no objects
can contact the guide bar nose and chain during
cutting, this can cause kickback.
• Never allow someone to hold the log during cutting.
• Never stabilize log with leg or feet.
Bucking
Kickback
• When bucking on a slope, always stand on the uphill
side of the log. To maintain complete control of the
pruning saw when cutting through the log, release
the cutting pressure near the end of the cut without
relaxing your grip on the grasping surfaces. Do not
let the chain contact the ground. After completing
the cut, wait for the saw chain to stop before you
move the pruning saw. Always stop the motor before
moving from tree to tree.

Turning the Tool On / O
Hold the pruning saw
on the trigger handle and your left
hand on the body grip. Position
your body and arm(s) to allow you
to resist kickback forces. A rm grip
together with a sti left arm will help you maintain
control of the saw if kickback occurs. Keep body to
the left of the chain line. Never straddle the saw
or chain, or lean over past the chain line.
Wear non-slip gloves for maximum grip and
protection.
1. Insert the battery pack.
2. Grip both handles securely, keeping body out of
line with the chain.
with your right hand
Reaction
• Sometimes it is impossible to avoid pinching (with
just standard cutting techniques) or dicult to predict
which way a log will settle when cut. To avoid pinch-
ing while cutting, rotate or move the log so that the
pinch is eliminated.

WARNING
Overbucking (crosscutting)
Overbucking
Begin on the top side of the log with the bottom of the
saw against the log; exert light pressure downward.
Note that the saw will tend to pull away from you.
Underbucking (crosscutting)
Underbucking
Begin on the under side of the log with the top of the
saw against the log; exert light pressure upward. During underbucking, the saw will tend to push back at
you. Be prepared for this reaction and hold the saw
rmly to maintain control.
Limbing
Never climb into a tree to limb or
platforms, a log, or in any position which can
cause you to lose your balance or control of the
saw.
Cut limbs one at a time and leave support limbs
prune. Do not stand on ladders,
under tree until log is cut.
Limbing is removing branches from a fallen tree.
• Work slowly, keeping both hands on the pruning
saw with a rm 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 o the ground while cutting.
• 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 bot-
tom up to avoid binding the pruning saw.
• Keep the tree between you and the pruning saw
while limbing. Cut from the side of the tree opposite
the branch you are cutting.
Pruning
If the limbs to be pruned are above
sional to perform the pruning. Failure to do so
could result in serious personal injury.
First Cut

Finishing Cut
Pruning is trimming limbs from a live tree.
• Work slowly, keeping both hands on the pruning
saw with a rm 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 danger-
ous. Leave this operation for professionals.
• Do not cut above shoulder height as a saw held
higher is dicult to control against kickback.
• When pruning trees it is important not to make the
nishing cut next to the main limb or trunk until
you have cut o 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 rst cut.
• Your second cut should overbuck to drop the
branch o.
• Now make your nishing cut smoothly and neatly
against the main member so the bark will grow back
to seal the wound.

Springpoles
Springpoles are dangerous and
the operator to lose control of the pruning saw.
This could result in severe or fatal injury to the
operator.
Springpole
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
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.

jointer. After lowering each
depth gauge, restore original
shape by rounding the front.
Be careful not to damage
adjoining drive links with the
edge of the le.
Depth gauges must be ad-
justed with the at le in the
same direction the adjoining cutter was led with the
round le. Use care not to contact cutter face with
at le when adjusting depth gauges.
When the guide bar shows signs of wear, ip the
guide bar from bottom to top on the saw to distrib-
ute the wear for maximum bar life. The bar should
be cleaned every day of use and checked for wear
and damage.
Feathering or burring of the bar
rails is a normal process of
bar wear. Such faults should
be smoothed with a le as
soon as they occur.
A bar with any of the following
faults should be replaced.
• Wear inside the bar rails which permits the chain to
lay over sideways.
• Bent guide bar.
• Cracked or broken rails.
• Spread rails.
Lubricate guide bars with a sprocket at their tip
weekly. Using a grease syringe, lubricate weekly in
the lubricating hole. Turn the guide bar and check
that the lubrication holes and bar rails are free from
impurities.
NOTE: Do not replace the screw with an ordinary
screw. Use only identical replacement parts from the
manufacturer when replacing parts.

To reduce the risk of personal injury and damage, never immerse
your tool, battery pack or charger in liquid or
allow a liquid to ow inside them.
Clean dust and debris from vents. Keep handles
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain cleaning agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use ammable or
combustible solvents around tools.
