GENERAL 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 atmospheres,
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. Unmodied 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 electric
shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
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
suitable for outdoor use reduces the risk of electric
shock.
6. 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.
NOTE: The term “residual current device(RCD)” may
be replaced by the term “ground fault circuit interrupter
(GFCI)” or “earth leakage circuit breaker(ELCB)”
GENERAL SAFETY WARNINGS

8 9
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 inuence 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 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, jewellery 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
GENERAL SAFETY WARNINGS GENERAL SAFETY WARNINGS
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 preventive safety measures reduce the
risk of starting the power tool accidentally.
4. 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.
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.

PRODUCT SAFETY WARNINGS
Use of the power tool for operations different from
those intended could result in a hazardous situation.
Service
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.
SPECIAL SAFETY INSTRUCTIONS FOR CORDLESS
POLE SAW
- Keep all parts of the body away when the saw is
operating. Before you start the pole saw, make sure
the saw chain is not touching anything. A moment
of inattention while operating pole saws may cause
entanglement of your clothing or body with the
chainsaw.
- Carry the chain saw by the front handle with the saw
chain stopped and the guide bar pointing to the rear.
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.
- 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.
- Do not operate a chain saw in a tree unless specically
trained to do so. Improper operation of a chain saw in
a tree, may result in personal injury.
PRODUCT SAFETY WARNINGS
- Always keep proper footing and operate the pole
saw only when standing on a xed, secure and level
surface. Slippery or unstable surfaces such as ladders
may cause a loss of balance or control of the pole
saw.
- When cutting a limb that is under tension be alert
for spring back. When the tension in the wood bers
is released the spring loaded limb may strike the
operator and/or throw the pole saw out of control.
- 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.
- 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.Follow instructions for lubricating,
chain tensioning and changing accessories.
- Improperly tensioned or lubricated chain may either
break or increase the chance for kickback.
- 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 pole saw for purposes
not intended. For example: Do not use pole saw
for cutting plastic, masonry or non-wood building
materials. Use of the pole saw for operations different
than intended could result in a hazardous situation.
- This chain saw is not intended for tree felling. Use of
the chain saw for operations different than intended
could result in serious injury to the operator or

12 13
PRODUCT SAFETY WARNINGS
bystanders.
- Hold the chain saw by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring or its own cord. Saw chains contacting a “live”
wire may make exposed metal parts of the chain saw
“live” and could give the operator an electric shock.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK
1. 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.
2. Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and back
towards the operator.
3. Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards the
operator.
4. 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.
5. 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.
PRODUCT SAFETY WARNINGS
- 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 over reach 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 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.
PRECAUTIONS FOR POLE SAW
1. Never stand directly under the limb you are cutting.
Always position yourself out of the path of falling
debris.
2. Never stand on a ladder or other type of unstable
support while using the pole saw.
3. Always use both hands to operate pole saw. Keep a
rm, steady pressure on the pole saw while cutting but
do not try to force the saw through the wood.
4. Do not use the pole saw to cut limbs larger in diameter
than the length of the guide bar.
5. Keep other people away from cutting end of pole saw
and at a safe distance from work area.
6. Do not use pole saw near cable, electric power or
telephone lines. Maintain a minimum clearance of 10
feet from all power lines.
