Other Safety Precautions

Vibration and Cold
It is believed that a condition called Raynaud's
Phenomenon, which affects the ngers of
certain individuals, may be brought about by
exposure to cold and vibration.
Accordingly, your chain saw has shock mounts
designed to reduce the intensity of vibration
received through the handles.
Repetitive Stress Injuries
It is believed that overusing the muscles and
tendons of the ngers, hands, arms and
shoulders may cause soreness, swelling,
numbness, weakness and extreme pain to the
areas just mentioned.
To reduce the risk of repetitive stress injury,
do the following:
Machine Conditions
■ Do not operate a chain saw that is
damaged, improperly adjusted, or not
completely and securely assembled.
■ Do not operate the chain saw with a loose
or defective silencer.
Cutting
CAUTION
Do not touch hot surfaces of cylinder
cover and silencer after you used the
chain saw.
■ Do not operate a chain saw in a tree unless
you have been speci cally trained to do so.
■ Keep all parts of your body away from the
saw chain when the engine is running.

Exposure to cold and vibration may cause
tingling and burning followed by loss of color
and numbness in the ngers. We strongly
recommend your taking the following
precautions because the minimum exposure
which might trigger the ailment is unknown.
■ Keep your body warm, especially the head
and neck, feet and ankles, and hands and
wrists.
■ Maintain good blood circulation by
performing vigorous arm exercises
during frequent work breaks and also by
not smoking.
■ Avoid using your wrist in a bent, extended
or twisted position. Instead, try to
maintain a straight wrist position. Also,
when grasping, use your whole hand, not
just the thumb and index nger.
■ Take periodic breaks to minimize repetition
and rest your hands.
■ Be sure that the saw chain stops moving
when the throttle control trigger is released.
■ Use extreme caution when cutting small-
size brush and saplings because slender
material may catch the saw chain and be
whipped toward you or pull you off
balance.
■ Stay on the uphill side when bucking or
limbing logs which might roll when cut.
■ When cutting a limb that is under tension,
be alert for spring back so that you will not
be struck by the limb or chain saw when
the tension in the wood bers is released.
■ Limit the number of hours of chain saw
operation. Try to ll a part of each work
day with jobs other than chain sawing.
■ If you experience discomfort, redness
and swelling of the ngers, followed by
whitening and loss of feeling, consult your
physician before further exposing yourself
to cold and vibration.
■ Reduce the speed and force in which you
do the repetitive movement.
■ Do exercises to strengthen the hand and
arm muscles.
■ See a doctor if you feel tingling, numbness
or pain in the ngers, hands, wrists or arms.
WARNING
Do not modify a chain saw in any way.
Use only shindaiwa recommended
parts and accessories when repairing
and servicing.
■ Cutting while on a ladder is extremely
dangerous because the ladder can slip and
your control of the chain saw is limited.
Working aloft should be left to
professionals.
■ Keep both feet on the ground. Do not work
from off-the-ground positions.
■ Stop the engine before setting the chain
saw down.
