SPECIFIC SAFETY RULES
Kickback is a dangerous reaction that can lead to serious
injury. Kickback may occur when the moving chain con-
tacts an object at the upper portion of the tip of the guide
bar or when the wood closes in and pinches the 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 chain is pinched along the top
of the guide bar, the guide bar can be driven rapidly back
toward the operator. Either of these reactions can cause
loss of tool control which can result in serious injury. Do
not rely exclusively upon the safety devices built into the
tool. As a pruner user, you should take several steps to
keep your cutting jobs free from accident or injury.
