Black Max BM5020 Operator's Manual page 17

WARNING:
KICKBACK occurs when the moving chain
contacts an object at the upper portion of the
tip of the guide bar or when the wood closes in
and pinches the saw chain in the cut. Contact
at the upper portion of the tip of the guide bar
can cause the chain to dig into the object and
stop the chain for an instant. The result is a
lightning-fast reverse reaction which kicks the
guide bar up and back toward the operator. If
the saw chain is pinched along the top of the
guide bar, the guide bar can be driven rapidly
back toward the operator. Either of these reac-
tions can cause loss of saw control, which can
result in serious injury.
Do not rely exclusively upon the safety devices
built into the saw. As a chain saw user, you
should take steps to keep your cutting jobs
free from accident or injury. See General Safety
Rules for more details.
KICKBACK PRECAUTIONS
See Figures 15 - 16.
Rotational kickback occurs when the moving chain
contacts an object at the Kickback Danger Zone of
the guide bar. The result is a lightning-fast reverse
reaction, which kicks the guide bar up and back
towards the operator. This reaction can cause loss
of control, which can result in serious injury.
PREPARING FOR CUTTING
PROPER GRIP ON HANDLES
See Figure 17.
See General Safety Rules for appropriate safety
equipment.
 Wear non-slip gloves for maximum grip and
protection.
 Hold the saw firmly with both hands. Always
keep your left hand on the front handle and your
right hand on the rear handle so that your body
is to the left of the chain line.
