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 your body and arm positioned 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 WARNINGS

It has been reported that vibrations from hand-
held tools may contribute to a condition called
English (original instructions)
Raynaud's Syndrome in certain individuals.
Symptoms may include tingling, numbness
and blanching of the figures ,ususlly apparent
upon exposure to cold and dampness, diet,
smoking and work practices are all thought
to contribute to the development of these
symptoms. It is presently unknown what,
if any, vibrations or extent of exposure
may contribute to the condition. There are
measures that can be taken by the operator
to possibly reduce the effects of vibration:
„ Keep your body warm in cold weather,
when operating the unit wear gloves to
keep the hands and wrists warm. It is
reported that cold weather is a major factor
contributing to Raynaud's Syndrome.
„ After each period of operation, exercise to
increase blood circulation.
„ Take frequent work breaks. limit the
amount of exposure per day.
If you experience any of the symptoms of this
condition, immediately discontinue use and
see your physician about these symptoms.
The recommended
„
of this chain saw is 153mm (6 in.) and
smaller to prolong the life of the tool and
allow for safest operation.
Cutting logs with a diameter larger than
„
this will cause excess wear on your
tool. Logs with a maximum diameter of
229mm (9in.) can be cut, but should only
be done so rarely and with caution.
The integral spiked bumper is designed
„
to assist cutting. When forced against the
log while cutting it provides a more stable
pivot point.
Any chainsaw is potentially lethal if used
„
inappropriately. It is strongly suggested
that you seek professional training in the
safety and use of this tool.
