SAFETY INFORMATION
Work Area Safety
■ Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
■ Do not operate power tools in explosive atmospheres, such
as in the presence of ammable Iiquids, 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. Unmodied 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.
Read all safety directions and instructions. Omissions in
the compliance with safety directions and instructions can
cause electrical shock, re and/or severe injuries.
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.
WARNING

9
SAFETY INFORMATION
■ 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. Use a surge
protector with a release current of 30 mA or less.
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 inuence of drugs,
alcohol or medication. A moment of inattention white
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 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.
■ 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, jewellery or long hair can be caught in
moving parts.

10
SAFETY INFORMATION
■ 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.
■ WARNING! During operation, this electric tool generates an
electromagnetic eld which, under certain circumstances,
may impair the functionality of active or passive medical
implants. To reduce the risk of serious or lethal injuries, we
recommend that persons with medical implants consult
their doctor and the manufacturer of their medical implant
before operating the machine.
■ Change your working position regularly. Long use of
the equipment can result in vibration-related circulatory
disorders in the hands. However, the length of use can be
extended by using suitable gloves or taking regular breaks.
Note that a personal tendency for poor circulation, low
outdoor temperatures, or high gripping forces during work
will reduce the length of use.
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 cannot 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.

11
SAFETY INFORMATION
■ 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 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.
■ Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less Iikely 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.
■ 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.
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.

SAFETY INFORMATION
Chain Saw Safety Warnings
■ Keep all parts of the body away from the sawing chain
when the chain saw is operating. Before you start the
chain saw, make sure the sawing chain is not contacting
anything. A moment of inattention white operating chain
saws may cause entanglement of your clothing or body
with the sawing chain.
■ 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 conguration increases the
risk of personal injury and should never be done.
■ Hold the chain saw by insulated gripping surfaces only,
because the sawing chain may contact hidden wiring or its
own cord. Sawing chains contacting a “live” wire may make
exposed metal parts of the chain 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 clothing will reduce personal injury
from ying debris or accidentaI contact with the sawing
chain.
■ Do not operate a chain saw in a tree. Operation of a chain
saw while up in a tree may result in personal injury.
■ 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.
■ When cutting a Iimb that is under tension, be alert for spring
back. When the tension in the wood bres is released the
spring loaded Iimb may strike the operator and/or throw the
chain saw out of control.

13
SAFETY INFORMATION
■ Use extreme caution when cutting brush and saplings.
The slender material may catch the sawing 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 Iikelihood
of accidentaI contact with the moving sawing chain.
■ Follow instructions for lubricating, chain tensioning and
changing accessories. Improperly tensioned or lubricated
chain may either break or increase the chance for kickback.
■ Cut wood only. Do not use chain saw for purposes not
intended. For example: do not use the chain saw for cutting
plastic, masonry or non-wood building materials. Use of
the chain saw for operations different 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.
■ 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 bystanders.
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 sawing 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.

14
SAFETY INFORMATION
■ Pinching the sawing 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:
a) 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.
b) 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.
c) Only use replacement bars and chains specied by the
manufacturer. Incorrect replacement bars and chains
may cause chain breakage and/or kickback.
d) Follow the manufacturer´s sharpening and maintenance
instructions for the sawing chain. Decreasing the depth
gauge height can lead to increased kickback.
e) Do not saw with the tip of the blade. This can lead to a
kickback.
f) Ensure that there aren’t any objects on the ground that
you can trip over.
