4.8.1 Kickback
Kickback can be caused for the following reasons:
– The rotating saw chain in the upper quadrant of the bar
nose makes contact with a hard object and is suddenly
braked.
– The rotating saw chain is pinched at the bar nose.
The chain brake cannot prevent kickback.

direction of the operator. The operator can lose control of
the saw and be seriously or fatally injured.
► Hold the saw firmly with both hands.
► Always keep your body out of the plane of the cutting
attachment.
► Operate the saw as described in this instruction manual.
► Do not cut with the upper quadrant of the bar nose.

saw chain.
► Use a reduced kickback saw chain.
► Use a guide bar with a narrow radius nose.
► Always cut with the chain running at full speed.
4.8.2 Pull-in
The saw is pulled away from the operator when the bottom
of the bar is used for cutting.
WARNING
￭ If the rotating chain makes contact with a hard object and
is suddenly pinched, the saw is abruptly jerked away from
the operator. The operator can lose control of the saw and
be seriously or fatally injured.
► Hold the saw firmly with both hands.
