Chain Saw Safety Warnings

General safety warnings for chain saws
a) Keep all parts of your body away from the
saw chain when the chain saw is operating.
Before you start the chain saw, make sure
the saw chain does not touch anything. A
moment of inattention while operating chain
saws may cause entanglement of your cloth‐
ing or body with the saw chain.
b) 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.
c) Hold the chain saw by insulated gripping sur‐
faces only, because the saw chain may con‐
tact 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.
d) Wear eye protection. Further protective
equipment for hearing, head, hands, legs
and feet is recommended. Adequate protec‐
tive equipment will reduce personal injury
from flying debris or accidental contact with
the saw chain.
e) Do not operate a chain saw in a tree, on a
ladder, from a rooftop, or any unstable sup‐
port. 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 a fixed,
secure and level surface. Slippery or unsta‐
ble 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 in the
wood fibers 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 or pull
you off balance.
Carry the chain saw by the front handle with
i)
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.
j) Follow the instructions for lubricating, chain
tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kick‐
back.
k) Cut wood only. Do not use chain saw for pur‐
poses not intended. For example: do not use
chain saw for cutting metal, plastic, masonry
or non-wood building materials. Use of the
chain saw for operations different than inten‐
ded 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 oper‐
ator or bystanders while felling a tree.
m) Follow all the instructions for removing accu‐
mulated material from the chainsaw and for
storing or servicing the chainsaw. Make sure
that the switch is set to "Off" and the battery
block has been removed.Unexpected startup
of the chainsaw during removal of accumula‐
ted material or during maintenance work may
cause severe injuries.
27.9 Causes and operator preven‐
tion 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.
