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 em-
ployer should be used; otherwise, sung tting clothing,
protective 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 fueling, servicing or transporting your chain saw
switch off the engine. To help prevent re, restart your
chain saw at least 3 m from the fueling area.
4. When using a chain saw a re extinguisher should be
available.
5. When felling, keep at least 2 tree lengths between your-
self and your fellow workers.
6. Plan your work; assure yourself of an obstacle-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 start-
ing the chain saw and control the chain saw with a rm
grip on both handles when it is in operation. Keep han-
dles dry, clean and free of oil. A chain saw should never
be carried with the engine 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 damaged, improperly
adjusted, or is not completely and securely assem-
bled. 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 carbon monoxide poisoning. Operate the
chain saw in well-ventilated areas only.
11. Do not attempt a pruning or liming operation in a stand-
ing tree unless specically trained to do so.
12. Guard against kickback. Kickback is the upward
motion of the guide bar, which occurs 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 backward which may cause
serious injury.
(c) Always use two hands when operating the chain
saw.
(d) Use a rm grip, thumbs and ngers encircling the
handles.
(e) Don’t overreach.
(f) Avoid cutting above shoulder height.
(g) Follow the manufacture’s instructions for sharpen-
ing and maintenance of the saw chain.
13. When boring with the chain saw, the initial cut should
be introduced with the lower part of the nose (tip) until
the hole is sufciently large so as to introduce the entire
nose (tip) of the guide bar. This technique should re-
duce the danger of kickback.
RULES FOR SAFE OPERATION
14. A chain saw is intended for two-handed use.
Serious injury to the operator, helpers and/or by-
standers may result from one-handed operation.
CAUTION
A. Allow your chain saw to cool before refueling,
and do not smoke while refueling.
B. Do not allow other persons or animals close to
running chain saw or close to where a tree is be-
ing 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 be alert
for spring-back.
