1. Fatigue causes carelessness. Be more
cautious before rest periods and before
the end of your shift.
2. Personal protective clothing required by
your safety organizations, government
regulations, or your employer should be
used; otherwise, sung fitting clothing, pro-
tective eyewear, safety footwear and hand,
leg and hearing protection should be worn.
Note: Personal protective clothing
should meet the requirements
of applicable Standards.
3. Before fuelling, servicing or transporting
your chain saw switch off the engine. To
help prevent fire, restart your chain saw
at least 3 m (10 ft) from the fuelling area.
4. When using a chain saw a fire extinguisher
should be available.
5. When felling, keep at least 2 tree lengths
between yourself and your fellow workers.
6. Plan your work; assure yourself of an ob-
stacle-free work area and, in the case of
felling, of an escape path from the falling
tree.
7. Follow instructions in your operator’s
manual for starting the chain saw and con-
trol the chain saw with a film grip on both
handles when it is in operation. A keep
handles dry, clean and free of oil. A chain
saw should never be carried with the en-
gine running.
8. When transporting your chain saw, use the
appropriate transportation covers that
should be available for the guide bar and
saw chain.
9. Never operate a chain saw that is dam-
aged, improperly adjusted, or is not com-
pletely and securely assembled. Be sure
that the saw chain stops moving when the
throttle control trigger is released. Never
adjust the guide bar or saw chain when
the engine operating.
10. Beware of carton monoxide poisoning. Op-
erate the chain saw in well-ventilated ar-
eas only.
RULES FOR SAFE OPERATION
11. Do not attempt a pruning or liming opera-
tion in a standing tree unless specifically
trained to do so.
12. Guard against kickback. Kickback is the
upward motion of the guide bar, which oc-
curs when the saw chain, at the nose of
the guide bar, contact an object. Kickback
can lead to dangerous loss of the chain
saw.
TO AVOID KICKBACK:
(a) Contact of the guide bar tip with any
object should be avoided.
(b) Tip contact may cause the guide bar
to move suddenly upward and back-
ward which may cause serious injury.
(c) Always use two hands when operat-
ing the chain saw.
(d) Use a firm grip, thumbs and fingers
encircling the handles.
(e) Don’t overreach.
(f) Avoid cutting above shoulder height.
(g) Follow the manufacture’s instructions
for sharpening and maintenance of the
saw chain.
13. When boring with the chain saw, the ini-
tial cut should be introduced with the lower
part of the nose (tip) until the hole is suffi-
ciently large so as to introduce the entire
nose (tip) of the guide bar. This manoeuve
should reduce the danger of kickback.
14. A chain saw is intended for two-handed
use. Serious injury to the operator, help-
ers and/or bystanders may result from
one-handed operation.
CAUTION
A. Allow your chain saw to cool before refu-
eling, and do not smoke.
B. Do not allow other persons or animals
close to running chain saw or close to
where a tree is being felled.
C. Use extreme caution when cutting small
size brush and saplings because slender
material may catch the saw chain and be
whipped toward you.
D. When cutting a limb that is under tension
is alert for spring-back.
