• POLE SAW ATTACHMENT - A cutting head attached to a rigid tube, comprised of a guide bar, saw
chain, drive sprocket, and other components.
• COUPLER - A device that securely connects two sections of the unit together, such as the extension
boom and pole saw attachment.
• DRIVE SPROCKET - A toothed wheel that drives the saw chain.
• FRONT HANDLE (HANDLE) - A support handle located on the upper shaft housing on the powerhead.
• REAR HANDLE (SHAFT GRIP) - A support handle located near the engine on the powerhead.
• GUIDE BAR - A solid railed structure that supports and guides the saw chain.
• GUIDE BAR TIP - The tip or end of the guide bar.
• REDUCED-KICKBACK GUIDE BAR - A guide bar that has been demonstrated to reduce kickback
significantly.
• SAW CHAIN - A loop of chain with teeth designed to cut wood, which is driven by the engine and is
supported by the guide bar. The saw chain is composed of drive links, cutters and side links, held
together by rivets.
• LOW-KICKBACK SAW CHAIN - A saw chain that complies with the kickback performance
requirements of ANSI/OPEI B175.1-2012 when tested on a representative sample of pole saws.
Low-kickback saw chain significantly reduces the chance of kickback and the intensity of kickback,
due to specially designed depth gauges and guard links.
• REPLACEMENT SAW CHAIN - A saw chain that complies with the kickback performance
requirements of ANSI/OPEI B175.1-2012 when tested with specific pole saws. It may not meet the
ANSI/OPEI performance standards when used with other pole saws.
• SPIKED BUMPER - The pointed tooth (or teeth), at the front of the pole saw, used during pruning to
help pivot the saw and maintain a stable position while cutting.
• OILER CONTROL - A system for oiling the saw chain and guide bar.
• ON / OFF SWITCH - A device that immediately stops the engine when moved to the Off position.
• THROTTLE CONTROL - A device that, when operated in conjunction with the throttle lockout, is
used to start the engine and control the engine speed.
• THROTTLE LOCKOUT - A device that prevents the unit from accelerating accidentally. The throttle
control cannot be squeezed unless the throttle lockout is manually engaged.
• SPARK ARRESTER SCREEN - A device that retains carbon and other flammable particles over 0.023
inches (0.6mm) in size from the engine exhaust flow. Compliance with local, state and federal laws
and/or regulations governing the use of a spark arrester screen is the user's responsibility. Refer to
Spark Arrestor Note in the Safety section for additional information.
• KICKBACK - A sudden backward and/or upward motion of the guide bar and saw chain. Kickback
can occur if the upper portion of the guide bar tip touches an object while the saw chain is
spinning (rotational kickback). Kickback can also occur if the wood closes in and pinches the saw
chain inside the cut (linear kickback).
• ROTATIONAL KICKBACK - A sudden backward and upward motion of the guide bar and saw chain.
Rotational kickback can occur if the upper portion of the guide bar tip touches an object while the
saw chain is spinning. The guide bar and saw chain are then kicked up and back toward the
operator in a lightning-fast reverse reaction.
• LINEAR KICKBACK (PINCH KICKBACK) - A sudden backward motion of the guide bar and saw chain.
Linear (pinch) kickback can occur if the wood closes in and pinches the saw chain inside a cut. The
saw is then sent straight back toward the operator.
• NORMAL CUTTING POSITION - The positions assumed while making pruning cuts.
• PRUNING - The process of cutting limbs from a living tree.
