Safety Precautions for Chain Saw Users
D1. Kickback Safety Precautions for Chain Saw Users
WARNING!: 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 light¬
ning fast 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.
(1) With a basic understanding of kickback, you can
reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
(2) Keep a good firm grip on the saw with both
hands, the right hand on the rear handle, and the
left hand on the front handle, when the engine is
running. Use a firm grip with thumbs and fingers
encircling the chain saw handles. A firm grip will
help you reduce kickback and maintain control
of the saw. Don't let go.
(3) Make sure that the area in which you are cutting
is free from obstacles. Do not let the nose of
the guide bar contact a log, branch, or any other
obstacle which could be hit while you are
operating the saw.
(4) Cut at high engine speeds.
(5) Do not overreach or cut above shoulder height.
(6) Follow manufacturer's sharpening and
maintenance instructions for the saw chain.
(7) Only use replacement bars and chains specified
by the manufacturer or the equivalent.
D 2. Other Safety Precautions
(1) Do not operate a chain saw when you are
fatigued.
(2) Use safety footwear; snug-fitting clothing;
protective gloves; and eye, hearing, and head
protection devices.
(3) Use caution when handling fuel. Move the chain
saw at least 10 feet (3 m) from the fueling point
before starting the engine.
(4) Do not allow other persons to be near the chain
saw when starting or cutting with the chain saw.
Keep bystanders and animals out of the work
area.
(5) Do not start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree.
(6) Keep all parts of your body away from the saw
chain when the engine is running.
(7) Before you start the engine, make sure that the
saw chain is not contacting anything.
(8) Carry the chain saw with the engine stopped, the
guide bar and saw chain to the rear, and the
muffler away from your body.
(9) Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled. Be sure that the saw chain
stops moving when the throttle control trigger is
released.
(10) Shut off the engine before setting the chain saw
down.
(11) 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.
(12) When cuttting a limb that is under tension be
alert for springback so that you will not be struck
when the tension in the wood fibers is released.
(13) Keep the handles dry, clean, and free of oil or
fuel mixture.
(14) Operate the chain saw only in well-ventilated
areas.
(15) Do not operate a chain saw in a tree unless you
have been specifically trained to do so.
(16) Do not operate a chain saw above shoulder
height.
(17) All chain saw service, other than the items listed
in the operator's/owner's safety and
maintenance instructions, should be performed
by competent chain saw service personnel. (For
example, if improper tools are used to remove
the flywheel or if an improper tool is used to hold
the flywheel in order to remove the clutch,
structural damage to the flywheel could occur
and subsequently cause the flywheel to burst.)
(18) When transporting your chain saw, use the
appropriate guide bar scabbard.
Note:
This Appendix is intended primarily for the
consumer or occasional user. When using a chain
saw for logging purposes, refer to the Code of Federal
Regulations, Section 1910.266(5); 2.5.1. of American
National Standard Safety Requirements for Pulpwood
Logging, ANSI 03.1-1978: and relevant state safety
codes.
