OPERATING INSTRUCTIONS FOR USE WITH TRIMMER HEAD
WARNING: Always wear eye protec- tion. Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or other serious injury.
Before trimming, bring engine to a speed suffi- cient to cut material to be trimmed.
Do not run the engine at a higher speed than necessary. The cutting line will cut efficiently when the engine is run at less than full throttle. At lower speeds, there is less engine noise and vibration. The cutting line will last longer and will be less likely to “weld” onto the spool.
Always release the throttle trigger and allow the engine to return to idle speed when not cutting.
To stop engine:
SRelease the throttle trigger.
SMove the ON/OFF switch to the OFF posi- tion.
CUTTING METHODS
WARNING: Use minimum speed and do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), which can damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard.
SThe tip of the line does the cutting. You will achieve the best performance and mini- mum line wear by not crowding the line into the cutting area. The right and wrong ways are shown below.

RightWrong
S The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fences.
SFor trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially:
S During light duty cutting.
S Near objects around which the line can wrap such as small posts, trees or fence
wire.
SFor mowing or sweeping, use full throttle for a good clean job.
