TYPES OF CUTTING

A. BASIC CUTTING TECHNIQUE

1. IMPORTANT POINTS.

Cut wood only. D6 not cut metal, plastics,

masonry, non-wood, building materials; etc.

Stop the saw if the chain strikes a foreign
object. Inspect the unit and repair or replace
parts as necessary.

c. Keep the chain out of dirt and sarid. Even a

thus, increase the possibility of kickback.

2. UNDERSTAND REACTIVE FORCES

Pinch-Kickbackand Pull-In occur when the chain
is suddenly stopped by being pinched, caught, or
by contacting a foreign object in the wood. This
results in a reversal of the chain force u^d to cut wood

and causes the saw to move in the opposite direction of
chain rotation. Either reaction can result in loss of con­

trol and possible serious personal injury.

A KICKBACK WARNING

Kickback can occur when the moving chain contacts an

object at the upper portion of the tip of the g ulde bar or
when the wood closes in and pinchesthe saw chain in
the cut. Contact at the upper portion of the tip of the

stop the chain for an instant. The result ts a iightning
fast, reverse reaction which kicks the guide bar up and

back towaid the operator. If the saw chain is pinched
along the top of the guide bar, the guide har can be
