OPERATING INSTRUCTIONS
It is recommended that the engine not be operated for longer than 1 minute at full throttle.
OPERATING POSITION
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.
When operating unit, stand as shown and check for the following:
SWear eye protection and heavy clothing. S Hold trigger handle with your right hand and
assit handle with left hand. S Keep unit below waist level.
S Cut only from your left to your right to ensure debris is thrown away from you. Without bending over, keep line near and parallel to the ground and not crowded into material being cut.
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 en- gine to return to idle speed when not cutting.
To stop engine:
SRelease the throttle trigger.
S Push and release the engine ON/STOP switch.
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.
Cut only from your left to your right.
SFor mowing or sweeping, use full throttle for a good clean job.
