KEY CHAIN SAW TERMS
Pinch Specically the closing-in of the wood which pinches and
stops the chain along the top rails of the guide bar during
a cut. This can result in the chain saw being propelled
straight back toward the operator (called a Linear
Kickback). Pinch can also occur on the lower rails of the
bar, resulting in the chain saw being pulled away from the
operator.
Push And Pull When cutting is done along the bottom rails of the guide
bar, the reaction on the saw is to pull away from the
operator. When the top of the guide bar is used, the
reaction pushes the saw towards the operator. Both
are normal reactions which must be controlled by the
operator.
Reduced-
Kickback Guide
Bar
Guide bars which are recognized by the ANSI Standard
B175.1 as having as small or reduced radius nose to
reduce the potential kickback area.
Low Or
Reduced-
Kickback Saw
Chain
Saw chain which has been demonstrated to reduce
kickback on a selected group of chain saw models during
ANSI testing. Before using “reduced kickback” chain,
ask your dealer to determine if your chain saw can
accommodate “reduced-kickback” chain and still meet
the 45-degree CKA requirement explained on page 17.
Skating When the chain saw fails to dig in during a cut, the guide
bar can begin hopping or dangerously skidding along the
surface of the log or branch, possibly resulting in the loss
of control of the chain saw. To prevent or reduce skating,
hold the chain saw with two hands and make sure the
saw chain establishes a groove for cutting.
Throttle Trigger Located in the rear handle, it is used to control the speed
of the engine.
Throttle Trigger
Latch Button
The control used on some chain saws to set the throttle
for a fast idle speed, which may be required to start a
cold engine. The throttle can be unlatched by squeezing
and releasing the throttle trigger.
Throttle Trigger
Lockout Lever
A safety lever on the top of the top/rear handle which
must be depressed before the throttle trigger can be
activated. When the operator lets go of the top/rear
handle, the throttle will be locked in idle position.
