DEFINITION OF TERMS

UNIT - Power head, handles, cutting assembly and pole.

GASOLINEANDELECTRICPOWEREDTERMS CHOKE LEVER - The engine control attached to the carburetor that is used to enrich the fuel mixture for cold starting. Refer to Operator’s Manual for more details about correct position and use of the choke lever.

CLUTCH - The mechanism that transmits the rotation of the engine’s crankshaft to the cutting assembly.

DIELECTRIC MATERIAL - A material that reduces the likelihood of shock or electrocution from non-intentional contact during operation by providing protection against current flow through the unit to the operator.

GAUGE - A term that is used to describe the size of wire required when using extension cords with electric units over specific distances.

GFCI - Ground Fault Circuit Interrupter. An electrical circuit breaking device which provides protection against electrical shock hazards.

IGNITION/STOP SWITCH - An electrical switch which allows the engine to start and run, and turns the engine off. Refer to Operator’s Manual to learn and understand the stop and start procedure.

THROTTLE TRIGGER - The device that controls the fuel and air flow to the gasoline engine, either increasing or decreasing the engine’s RPM. Refer to the Operator’s Manual for an illustrated description.

THROTTLE TRIGGER LOCKOUT LEVER - A lever on the top of the throttle handle which must be depressed before the throttle can be activated. When

the operator releases the throttle trigger lockout lever, the throttle trigger will lock in the idle position.

THROTTLE TRIGGER/STOP SWITCH - An electrical switch which allows the electric motor to start and run, and turns the motor off when released. Refer to Operator’s Manual to learn and understand the stop and start procedure.

THROTTLING BACK - Releasing the throttle trigger to allow a decrease in engine speed (RPM).

THROTTLING UP - To increase the engine’s RPM by depressing the throttle trigger to desired level.

GENERALTERMS

ANSI Z87.1 - The established standard for eye protection devices set forth by the American National Standards Institute.

BALLISTIC - A special material used in protection devices designed to reduce the risk of penetration from saw chain contact.

BINDING - Closing the cut or shifting the wood, possibly trapping the saw blade in the cut. Binding includes pinching. (Also, see PINCH on page 6.)

BRANCH - A secondary shoot or stem arising from one of the main axes of a tree or woody plant.

BRANCH COLLAR - Trunk tissue that forms around the base of a branch between the main stem and the branch.

BRUSHING OUT - Cutting or otherwise removing undergrowth and brush in the cutting area and along the planned path of retreat.

BUCKING - Generally the standard cross cuts made to section a log or felled tree. Variations include overbucking (cutting from top down) and underbucking (from under- side).

CHAIN TENSIONER - The device which permits precise adjustment of the saw chain tension.

CHAPS - Specially designed leg protection which can reduce the risk of injury due to contact with a moving saw chain.

CHOKE - The engine control used to enrich the fuel mixture for cold starting.

CLEARING - Removing undergrowth and saplings from an area.

CLOSURE - The process of woundwood covering a cut or other tree injury.

CROTCH - The angle formed at the attachment between a branch and another branch, leader, or trunk.

CROWN - The upper portion of a tree from the lowest branch on the trunk to the top.
