„ 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.
„ Follow all instructions when clearing jammed mate-
rial, storing or servicing the chain saw. Make sure the
switch is off and the battery pack is removed. Unex-
pected actuation of the chain saw while clearing jammed
material or servicing may result in serious personal injury.
„ 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 mov-
ing saw chain.
„ Follow instructions for lubricating, chain tensioning
and changing the bar and chain. 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 chain saw for
cutting plastic, masonry or non-wood building mate-
rials. 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 under-
standing of the risks and how to avoid them. Serious
injury could occur to the operator or bystanders while
felling a tree.
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 reac-
tion, 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 operat-
ing procedures or conditions and can be avoided by taking
proper precautions as given below:
„ Maintain a firm grip, with thumbs and fingers encir-
cling 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 con-
CHAIN SAW SAFETY WARNINGS
trolled by the operator, if proper precautions are taken.
Do not let go of the chain saw.
„ Do not overreach and do not cut above chest 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 mainte-
nance instructions for the saw chain. Decreasing the
depth gauge height can lead to increased kickback.
„ Do not start cutting until you have a clear work area, se-
cure footing, and a planned retreat path from the falling
tree. Cluttered areas invite accidents.
„ Keep ALL children, bystanders, visitors, and animals out
of the work area while starting or cutting with the chain
saw. Do not let visitors contact chain saw or extension
cord.
„ Do not operate chain saw in explosive atmospheres,
such as in the presence of flammable liquids, gases, or
dust. Chain saws create sparks which may ignite the
dust or fumes.
„ Dress Properly – Wear snug fitting clothing. Always wear
heavy, long pants, long sleeves, overalls, jeans or chaps
made of cut resistant material or ones that contain cut
resistant inserts. Wear non-slip safety footwear. Wear
non-slip heavy duty gloves to improve your grip and to
protect your hands. Do not wear jewelry, short pants,
sandals, or go barefoot. Do not wear loose fitting clothing,
which could be drawn into the motor or catch the chain
or underbrush. Secure hair so it is above shoulder level.
Wear hearing and head protection.
„ Heavy protective clothing may increase operator fatigue,
which could lead to heat stroke. During weather that is
hot and humid, heavy work should be scheduled for early
morning or late afternoon hours when temperatures are
cooler.
„ Always wear eye protection with side shields marked
to comply with ANSI Z87.1 as well as hearing and head
protection when operating this equipment.
„ Always be aware of what you are doing when using the
chain saw. Use common sense. Do not operate the chain
saw when you are tired, ill, upset, or under the influence
of alcohol, drugs, or medication.
„ Do not expose the chain saw to rain.
„ Do not use the chain saw in damp or wet locations.
„ Stay alert and pay attention to what you are doing. Use
common sense when using this unit.
„ Keep all parts of your body away from the saw chain
when the unit is running.
