Essential Terms And Definitions - Remington RM4050 Manual Del Operador

• POLE SAW - A tool designed to prune branches with a saw chain. A pole saw is an integrated unit comprised of a motor, saw chain,
guide bar, pole, and grips (handles) that are designed to be held by two hands during operation.
• POLE SAW POWERHEAD - A pole saw without the saw chain, guide bar, pole, and grips (handles).
• DRIVE SPROCKET - A toothed wheel that drives the saw chain.
• FRONT HANDLE (POLE GRIP) - A support handle located at the upper end of the lower pole shaft.
• REAR HANDLE (SHAFT GRIP) - A support handle located at the lower end of the lower pole shaft.
• 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 motor 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.
• SWITCH - A device that, when operated, will complete or interrupt an electrical power circuit to the motor.
• SWITCH LINKAGE - A mechanism that transfers motion from the trigger to the switch.
• TRIGGER - A device that, when operated in conjunction with the switch lockout (trigger lockout), turns the motor on. Releasing the trigger
immediately turns the motor off. The saw chain will then coast to a stop.
• SWITCH LOCKOUT (TRIGGER LOCKOUT) - A device that prevents the unit from starting accidentally. The trigger cannot be squeezed
unless the switch lockout (trigger lockout) is manually engaged.
• BATTERY RELEASE BUTTON - A device used to disconnect the battery from the battery charger and the unit.
• UPPER POLE SHAFT - A moveable rigid tube. Moving the upper pole shaft adjusts the overall length of the pole. The pole saw
powerhead is attached to the end of the upper pole shaft.
• LOWER POLE SHAFT - A rigid tube that houses and retains the upper pole shaft. The shaft grip, trigger, trigger lockout, and battery port
are connected to the end of the lower pole shaft.
• COUPLER - A device that securely connects the upper pole shaft and lower pole shaft.
• COLLAR - A device that allows the upper pole shaft to move freely when unlocked and holds the upper pole shaft in place when locked.
• 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.
