3. SAFETY REQUIREMENTS
Wear safety glasses and hearing pro-
tection. Further protective equipment for
head, hands, legs and feet is recommen-
ded. Adequate protective clothing will reduce
personal injury caused by flying debris or ac-
cidental contact with the saw chain.
Do not operate a chain saw in a tree. Ope-
ration 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 fi-
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 limb that is under tension
be alert for spring back. When the tension
in the wood fibres is released the spring loa-
ded 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 sto-
ring 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 lubricating, chain
tensioning and changing accessories. Im-
properly tensioned or lubricated chains may
either break or increase the chance of kick-
back.
Keep handles dry, clean, and free from oil
and grease. Greasy, oily handles are slip-
pery, causing loss of control.
Cut wood only. Do not use the chain saw
for purposes not intended. For example:
do not use the chain saw for cutting plas-
tic, masonry or non-wood building mate-
rials. Use of the chain saw for operations dif-
ferent than intended could result in a hazar-
dous situation.
G) 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 fin-
gers encirding the chain saw handles,
with both hands on the saw and position
your body and arm to allow you to re-
sist kickback forces. Kickback forces can
be controlled by the operator if proper pre-
cautions are taken. Do not let go of the chain
saw.
Do not overreach and do not cut above
shoulder height. This helps prevent uninten-
ded 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.
H) CHAIN SAW OPERATING TECHNIQUES
Always observe the safety regulations and use the
most suitable sawing techniques (see chapter
USING THE MACHINE
ples).
J) RECOMMENDATION FOR FIRST-TIME
USERS
Before felling or delimbing for the first time, make
sure:
–
you have been specifically trained to use this
type of equipment;
–
you have carefully read the safety regulations
and user instructions contained in this ma-
nual;
–
you practise first on logs on the ground or
attached to trestles, in order to get familiar
with the machine and the most suitable cut-
ting techniques.
