THE PUSH (PINCH KICKBACK) AND PULL REACTIONS
(Fig. 2B)
A = Pull
B = Solid objects
C = Push
Maintain a firm grip, with thumbs and fingers encircling
the chain saw handles, with both hands on the saw and
position your body and arm to allow you to resist
kickback forces. Kickback forces can be controlled by the
operator, if proper precautions are taken. Do not let go of
the chain saw.
Do not overreach and do not cut above shoulder height.
This helps prevent unintended tip contact and enables
better control of the chain saw in unexpected situations.
Only use replacement bars and chains specified by the
manufacturer. Incorrect replacement bars and chains may
cause chain breakage and/or kickback.
Follow the manufacturer's sharpening and
maintenance instructions for the saw chain. Decreasing
the depth gauge height can lead to increased kickback.
