saws may cause entanglement of your clothing or body
with the saw 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 configuration
increases the risk of personal injury and should never be
done.
 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.
 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 flying debris or accidental contact with
the saw 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 fixed, 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 limb that is under tension be alert for
spring back. When the tension in the wood fibres is
released the spring loaded limb may strike the operator
and/or throw the chain 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 fit 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 oiling, 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. Don't use chain saw for purposes not
intended. For example: do not use 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.
 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 firm grip, with thumbs and fingers
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 specified 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.

Additional safety warnings

 It is recommended that the first time user should have
practical instruction in the use of the chainsaw and the
protective equipment from an experienced operator. The
initial practice should be cutting logs on a saw horse or
cradle.
 This tool is not intended for use by persons (including
children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction
concerning use of the appliance by a person responsible
for their safety.
Children should be supervised to ensure that they do not
play with the appliance.
 Children and juveniles, with the exception of
apprentices older than 16 years and under
supervision, may not operate the chain saw. The same
applies for persons who do not or do not sufficiently
know how to handle the chain saw. The operating
instructions should always be ready to hand. Persons unfit
or tired must not operate the chain saw.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more securely with both hands.
 Always ensure all handles and guards are properly
fitted when using the machine. Never attempt to use an
incomplete machine or one fitted with an unauthorized
modification.
 Wait until the machine has come to a standstill before
placing it down.
 Do not remove or modify the tip protector! Tool is fitted
with a tip protector to help protect against effect of kick
back by accidentally touching the tip of the tool against the
wood.
