SAFETY FEATURES

Numbers preceding the descriptions correspond with
the numbers on preceding page to help you locate the
safety feature.
1.LOW-KICKBACK CHAIN helps significantly reduce

kickback, or the intensity of kickback, due to spe-
cially designed depth gauges and Guard links.

9.LOCK / OFF BUTTON prevents accidental acceler-

ation of the saw motor. The trigger cannot be
squeezed unless lock/off button is depressed.

10.TRIGGER START / STOP SWITCH stops saw

motor when released.

12.HAND GUARD protects the operator’s left hand in

the event it slips off the front handle while saw is
running.

14.ELECTRIC MOTOR is double insulated for added

safety.

18.CHAIN CATCHER reduces the danger of injury in

the event saw chain breaks or derails during opera-
tion. The catcher is designed to intercept a whipping
chain.

RULES FOR SAFE OPERATION

KICKBACK SPECIFICS

Beware of:

Rotational Kickback

Kickback can lead to
dangerous loss of

control of the chain saw and result in serious
or fatal injury to the saw operator or to any-
one standing close by. Always be alert.
Rotational kickback and pinch-kickback are
major chain saw operational dangers and the
leading cause of most accidents.

WARNING:

A = Kickback path
B = Kickback reaction zone

KICKBACK SPECIFICS

Beware of:

Pinch Kickback (The push and pull reactions)

Fig.2

A = Pull
B = Solid objects
C = Push

KICKBACK may occur when the NOSE or TIP of the guide
bar touches an object, or when wood closes in and pinch-
es the saw chain in the cut.

Tip contact in some cases may cause a lightning-fast
reverse reaction, kicking the guide bar up and back
toward the operator.

PINCHING the saw chain along the BOTTOM of the guide
bar may PULL the saw forward away from the operator.
PINCHING the saw chain along the TOP of the guide bar
may PUSH the guide bar rapidly back toward the opera-
tor.

Any of these reactions may cause you to lose control of
the saw, which could result in serious personal injury.
