WARNING: Read all instructions.
GENERAL POWER TOOL SAFETY
WARNINGS
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.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in
explosive atmospheres, such as in the
presence of ammable liquids, gases
or dust.
Power tools create sparks which
may ignite the dust or fumes.
c) Keep children and bystanders at least
33’ (10M) away while operating a
power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) Power tool plugs must match the
outlet. Never modify the plug in any
way. Do not use any adaptor plugs
with earthed (grounded) power tools.
Unmodied plugs and matching outlets
will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric shock.
d) 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.
e) 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.
f) If operating a power tool in a damp
location is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric
shock.
3) Personal safety
a) 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 inuence of drugs, alcohol
or medication.
A moment of inattention
while operating power tools may result in
serious personal injury.
b) 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.
c) Prevent unintentional starting. Ensure
the switch is in the off 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 energising power
tools that have the switch on invites
accidents.
d) 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.

Safety Instructions
e) Do not overreach. Keep proper
footing and balance at all times. This
enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose
clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
g) 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.
4) Power tool use and care
a) 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.
b) Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with
the switch is dangerous and must be
repaired.
c) 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.
d) 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 dangerous in the hands
of untrained users.
e) Maintain power tools. Check for
misalignment 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 accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
g) Use the power tool, accessories, 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.
5) Battery tool use and care
a) Recharge only with the charger
specied 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.
b) Use power tools only with specically
designated battery packs. Use of any
other battery packs may create a risk of
injury and re.
c) 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.
d) Under abusive conditions, liquid may
be ejected from the battery; avoid
contact. If contact accidentally occurs,
WARNING: Read all safety warnings and instructions. Failure to
follow the warnings and instructions may result in electric shock,
re and/or serious injury.

SAVE THESE INSTRUCTIONS!
ush with water. If liquid contacts
eyes, seek additional medical help.
Liquid ejected from the battery may cause
irritation or burns.
6) Service
a) Have your power tool serviced by a
qualied repair person using only
identical replacement parts.
This will
ensure that the safety of the power tool is
maintained.
Chainsaw safety warnings
1. Keep all parts of the body away from
the saw chain when the chainsaw
is operating. Before you start the
chainsaw, make sure the saw chain
is not contacting anything.
A moment
of inattention while operating chainsaws
may cause entanglement of your clothing
or body with the saw chain.
2. Always hold the chainsaw with your
right hand on the rear handle and
your left hand on the front handle.
Holding the chainsaw with a reversed
hand conguration increases the risk
of personal injury and should never be
done.
3. 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.
4. Wear safety glasses and hearing
protection. Further protective
equipment for head, hands, legs
and feet is recommended. Adequate
protective clothing will reduce personal
injury by ying debris or accidental
contact with the saw chain.
5. Do not operate a chainsaw in a tree.
Operation of a chainsaw while up in a tree
may result in personal injury.
6. Always keep proper footing and
operate the chainsaw only when
standing on xed, secure and level
surface. Slippery or unstable surfaces
such as ladders may cause a loss of
balance or control of the chainsaw.
7. 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 chainsaw out of
control.
8. Use extreme caution when cutting
brush and saplings. The slender
material may catch the saw chain and
be whipped toward you or pull you off
balance.
9. Carry the chainsaw by the front
handle with the chainsaw switched
off and away from your body. When
transporting or storing the chainsaw
always t the guide bar cover. Proper
handling of the chainsaw will reduce the
likelihood of accidental contact with the
moving sawchain.
10. Follow instructions for lubricating,
chain tensioning and changing
accessories. Improperly tensioned or
lubricated chain may either break or
increase the chance for kickback.
11. Keep handles dry, clean, and free from
oil and grease. Greasy, oily handles are
slippery causing loss of control.
12. Cut wood only. Do not use chainsaw
for purposes not intended. For
example: do not use chainsaw for
cutting plastic, masonry or non-wood

building materials. Use of the chainsaw
for operations different than intended
could result in a hazardous situation.
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 chainsaw 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
incorrect operating procedures or conditions
and can be avoided by taking proper
precautions as given below:
• Maintain a rm grip: thumbs and
ngers encircling the chainsaw
handles with both hands on the saw,
and position your body and arm 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 chainsaw.
•Do not overreach and do not cut above
shoulder height. This helps prevent
unintended tip contact and enables better
control of the chainsaw in unexpected
situations.
•Only use replacement bars and chains
specied by the manufacturer. Incorrect
replacement bars and chains may cause
chain breakage and/or kickback.
•Follow the manufacturer’s sharpening
and maintenance instructions for the
saw chain.
Decreasing the depth gauge
height can lead to increased kickback.
SAFETY WARNINGS FOR BATTERY PACK
a) Do not dismantle, open or shred cells
of battery pack.
b) Do not expose battery pack to heat or
re. Avoid storage in direct sunlight.
c) Do not short-circuit a battery pack. Do
not store battery packs haphazardly in
a box or drawer where they may short-
circuit each other or be short-circuited by
conductive materials. 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.
d) Do not remove battery pack from its
original packaging until required for use.
e) Do not subject battery pack to
mechanical shock.
f) In the event of battery leaking, do not
allow the liquid to come into contact
with the skin or eyes. If contact has
been made, wash the affected area
with copious amounts of water and
seek medical advice.
g) Observe the plus (+) and minus
(–) marks on the battery back and
equipment and ensure correct use.
h) Do not use any battery pack which
is not designed for use with the
equipment.
i) Keep battery pack out of the reach of

SAVE THESE INSTRUCTIONS
Instructions concerning the proper
techniques for basic felling, limbing, and
cross-cutting:
1. Felling a tree
When bucking and felling operations are
being performed by two or more persons at
the same time, the felling operations should
be separated from the bucking operation by
a distance of at least twice the height of the
tree being felled. Trees should not be felled
in a manner that would endanger any person,
strike any utility line or cause any property
damage. If the tree does make contact
with any utility line, the company should be
notied immediately.
The chainsaw operator should keep on the
uphill side of the terrain as the tree is likely to
roll or slide downhill after it is felled.
An escape path should be planned and
cleared as necessary before cuts are started.
The escape path should extend back and
diagonally to the rear of the expected line of
fall as illustrated in Figure 1.
Before felling is started, consider the natural
lean of the tree, the location of larger
branches and the wind direction to judge
which way the tree will fall.
Remove dirt, stones, loose bark, nails,
staples and wire from the tree.
2. Notching undercut
Make the notch 1/3 the diameter of the
tree, perpendicular to the direction of fall as
illustrated in Figure 1. Make the lower horizontal
notching cut (W) rst. This will help to avoid
pinching either the saw chain or the guide bar
when the second notch (X) is being made.
3. Felling back cut
Make the felling back cut (Y) at least
2” (5 cm) higher than the horizontal notching
cut as illustrated in Figure 1. Keep the felling
back cut parallel to the horizontal notching
cut. Make the felling back cut so enough
wood is left to act as a hinge. The hinge wood
keeps the tree from twisting and falling in the
wrong direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree
Safety Instructions

10
should begin to fall. If there is any chance
that the tree may not fall in desired direction
or it may rock back and bind the saw chain,
stop cutting before the felling back cut is
complete and use wedges of wood, plastic
or aluminum (Z) to open the cut and drop the
tree along the desired line of fall (
3
).
When the tree begins to fall remove the
chainsaw from the cut, stop the motor, put
the chainsaw down, then use the retreat path
planned (
2
). Be alert for overhead limbs
falling and watch your footing. (See Figure 1.)

4. Limbing a tree
Limbing is removing the branches from
a fallen tree. When limbing, leave larger
lower limbs to support the log off the
ground. Remove the small limbs in one cut
as illustrated in Figure 2. Branches under
tension should be cut from the bottom up to
avoid binding the chainsaw.
Fig. 2
5. Bucking a log
Bucking is cutting a log into lengths. It is
important to make sure your footing is rm and
your weight is evenly distributed on both feet.
When possible, the log should be raised and
supported by the use of limbs, logs or chocks.
Follow the simple directions for easy cutting.
When the log is supported along its entire
length as illustrated in Figure 3, it is cut from
the top (overbuck), avoid contacting ground as
this will greatly reduce the chain sharpness.
Fig. 3
When the log is supported on one end, as
illustrated in Figure 4, cut 1/3 the diameter
from the underside (underbuck) (1). Then
make the nished cut by overbucking (2) to
meet the rst cut.

When bucking on a slope always stand on
the uphill side of the log, as illustrated in
Figure 6. When “cutting through”, to maintain
complete control, release the cutting pressure
near the end of the cut without relaxing your
grip on the chainsaw handles. Don’t let the
chain contact the ground. After completing
the cut, wait for the saw chain to stop before
you move the chainsaw. Always stop the
motor before moving from tree to tree.

Important: The chainsaw is not lled with oil. It is essential to ll
with oil before use. Never operate the chainsaw without chain
oil or at an empty oil tank level, as this will result in extensive
damage to the product.
Important: To allow proper ventilation of the oil tank, small
breather channels are provided between the oil ller cap and the
strainer to prevent leakage. Ensure machine is left in a horizontal
position when not in use.
Caution: Do not touch the ground with the chain. Ensure safety
clearance of 12” (30 cm).
Filling oil tank:
WARNING: Remove the battery pack before lling the oil tank.

LUBRICATION
NOTE: Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain
is automatically oiled during operation.
1. Set chainsaw on any suitable surface with oil ller cap facing upward.
2. Clean area around the oil ller cap with a cloth, and unscrew the cap by turning it
counter-clockwise.
3. Add chain oil until tank is full.
4. Avoid dirt or debris entering oil tank. Ret oil ller cap and tighten by turning clockwise
until hand tight.
It is important to use only the recommended bar and chain oil to avoid damage to the
chainsaw. Never use recycled/old oil. Use of non-approved oil will void the warranty.
Do not swallow. If swallowed, call a physician immediately. Keep out of reach of
children. Store away from heat or open ame.
Checking the Automatic Oiler
Proper functioning of the automatic oiler can be checked by running the chainsaw and
pointing the tip of the chain guide bar towards a piece of cardboard or paper on the ground.
If an increasing oil pattern develops on the cardboard, the automatic oiler is operating ne. If
there is no oil pattern, despite a full oil reservoir, contact a CTC customer service agent or a
CTC-approved service agent.
