OTHER SAFETY PRECAUTIONS
VIBRATION AND COLD
It is believed that a condition called
Raynaud’s Phenomenon, which
affects the fingers of certain
individuals, may be brought about
by exposure to cold and vibration.
Accordingly, your chain saw has shock mount
designed to reduce the intensity of vibration
received through the handles. Exposure to cold
and vibration may cause tingling and burning
followed by loss of colour and numbness in the
fingers. We strongly recommend you 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.
• Limit the number of hours of chain saw
operation. Try to fill a part of each work day
with jobs other than chain sawing.
• If you experience discomfort, redness and
swelling of the fingers, followed by whitening
and loss of feeling, consult your physician
before further exposing yourself to cold and
vibration.
MACHINE CONDITIONS
WARNING DANGER
Do not modify a chain saw in any way.
• 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. Be sure that the saw chain
stops moving when the throttle control trigger
is released.
REPETITIVE STRESS INJURIES
It is believed that overusing the muscles
and tendons of the fingers, 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:
• 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 finger.
• Take periodic breaks to minimize repetition
and rest your hands.
• 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 fingers, hands, wrists or arms.
