support. Operation of a chain saw in this
manner could result in serious personal injury.
f) Always keep proper footing and operate
the chain saw only when standing on
fixed, secure and level surface. Slippery
or unstable surfaces may cause a loss of
balance or control of the chain saw..
g) When cutting a limb that is under tension,
be alert for spring back. When the tension
of the wood fibres is released, the spring
loaded limb may strike the operator and/or
throw the chain saw out of control..
h) Use extreme caution when cutting brush
and saplings. The slender material may
catch the saw chain and be whipped toward
you and/or pull you off balance.
i) Carry the chainsaw by the front handle with
the chain saw switched off and away from
your body. When storing or transporting a
chainsaw always use the guide bar cover.
Proper handling of the chain saw will reduce
the likelihood of accidental contact with the
moving saw chain.
j) Follow the
lubrication, chain tension and changing
the bar and chain. Chains with incorrect
tension and lubrication can break and
increase the risk of kickback.
k) Cut wood only. Do not use the chainsaw
for purposes for which it is not intended.
For example: do not use an chainsaw for
cutting metal, plastic, masonry or other
non-wood materials. Using the chainsaw for
operations other than those intended could
result in a hazardous situation.
l) 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.
m) Follow all instructions when clearing
jammed material, storing or servicing the
chain saw. Make sure the switch is off and
the battery pack is removed. Unexpected
actuation of the chain saw while clearing
jammed material or servicing may result in
serious personal injury.
n) Recommendation that the first-time user
should, as a minimum, practise cutting
logs on a saw-horse or cradle.
o) Recommendation to have sharpening and
maintenance of the saw chain performed
by authorised service centres.
p) Keep handles dry, clean and free from oil
and grease. Greasy and oily handles are
slippery and can cause loss of control.

2.3 CAUSES OF KICKBACK AND
OPERATOR PROTECTION
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 chain saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
a) 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.
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
specified by the manufacturer. Incorrect
replacement guide bars and saw chains may
cause chain breakage and/or kickback.
d) Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
