2 - SAFETY PRECAUTIONS
THE PUSH (PINCH-KICKBACK) AND PULL
REACTIONS (Figure 2-5B)
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 lightening-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.
(See Fig. 2-5B “A”)
PINCHING the saw chain along the TOP of the guide bar
may PUSH the guide bar rapidly back toward the operator
(See Fig. 2-5B “C”).
Any of these reactions may cause you to lose control of the
saw, which could result in serious personal injury.
