Kickback
Kickback can be caused for the following reasons:

nose makes contact with a hard object and is suddenly
braked.

The chain brake cannot prevent kickback.

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.
