SAFETY WARNINGS
General power tool safety warnings
WARNING: Read all safety warnings and
all instructions. Failure to follow the warnings and
instructions may result in electric shock, re 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
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
1. 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.
2. 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.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. 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.
5.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
6. 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
1. 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.
2. 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.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. 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.
7. 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.
Power tool use and care
1. 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.
2. 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.
3. 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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.
4. Store idle power tools out of the reach of chil-
dren 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. 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
1. 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.
2. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
4 ENGLISH
3. 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 termi-
nals together may cause burns or a re.
4. Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
Service
1. 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.
2. Follow instruction for lubricating and chang-
ing accessories.
3. Keep handles dry, clean and free from oil and
grease.
Cordless Chain saw safety warnings
1.
Keep all parts of the body away from the saw
chain when the chain saw is operating. Before
you start the chain saw, make sure the saw chain
is not contacting anything. A moment of inattention
while operating chain saws may cause entanglement
of your clothing or body with the saw chain.
2. Always hold the chain saw with your right
hand on the rear handle and your left hand on
the front handle. Holding the chain saw with a
reversed hand conguration 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 chain saw in a tree. Operation of a
chain saw while up in a tree may result in personal injury.
6. Always keep proper footing and operate the
chain saw 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 chain saw.
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 chain saw 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 chain saw by the front handle with
the chain saw switched off and away from your
body. When transporting or storing the chain
saw always t the guide bar cover. Proper
handling of the chain saw will reduce the likelihood
of accidental contact with the moving saw chain.
10. Follow instructions for lubricating, chain ten-
sioning 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 chain saw for pur-
poses not intended. For example: do not use
chain saw for cutting plastic, masonry or nonwood building materials. Use of the chain saw for
operations different than intended could result in a
hazardous situation.
13. 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 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 incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
• Maintain a rm grip, with thumbs and ngers
encircling the chain saw 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 chain saw.
• Do not overreach and do not cut above
shoulder height. This helps prevent unintended tip contact and enables better control
of the chain saw in unexpected situations.
• Only use replacement bars and chains spec-
ied by the manufacturer. Incorrect replace-
ment 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.
5 ENGLISH
14. Before starting work, check that the chain
saw is in proper working order and that its
condition complies with the safety regulations.
Check in particular that:
• The chain brake is working properly;
• The run-down brake is working properly;
• The bar and the sprocket cover are tted
correctly;
• The chain has been sharpened and ten-
sioned in accordance with the regulations.
15. Do not start the chain saw with the chain cover
being installed on it. Starting the chain saw with
the chain cover being installed on it may cause
the chain cover to thrown out forward resulting in
personal injury and damage to objects around the
operator.
SAVE THESE INSTRUCTIONS.

After relling, hold the chain saw away from the
tree. Start it and wait until lubrication on saw chain is
adequate.
NOTICE: When lling the chain oil for the rst
time, or relling the tank after it has been com-
pletely emptied, add oil up to the bottom edge of
the ller neck. The oil delivery may otherwise be
impaired.
NOTICE: Use the saw chain oil exclusively for
Makita chain saws or equivalent oil available in
the market.
NOTICE: Never use oil including dust and parti-
cles or volatile oil.
NOTICE: When pruning trees, use botanical oil.
Mineral oil may harm trees.
NOTICE: Before the cutting operation, make sure
that the provided oil tank cap is screwed in place.
WORKING WITH THE CHAIN SAW
CAUTION: The rst time user should, as a
minimum practice, do cutting logs on a saw-horse
or cradle.
CAUTION: When sawing precut timber, use a
safe support (saw horse or cradle). Do not steady
the workpiece with your foot, and do not allow
anyone else to hold or steady it.
CAUTION: Secure round pieces against
rotation.
CAUTION: Keep all parts of the body away
from the saw chain when the motor is operating.
CAUTION: Hold the chain saw rmly with
both hands when the motor is running.
CAUTION: Do not overreach. Keep proper
footing and balance at all times.
NOTICE: Never toss or drop the tool.
NOTICE: Do not cover the vents of the tool.
Bring the bottom edge of the chain saw body into
contact with the branch to be cut before switching on.
Otherwise it may cause the guide bar to wobble, result-
ing in injury to operator. Saw the wood to be cut by just
moving it down by using the weight of the chain saw.
If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue sawing
and draw the chain saw back a little; then apply the
spike bumper a little lower and nish the cut by raising
the handle.
