When operating unit, clip shoulder strap onto clamp, stand as shown and check for the fol- lowing:

SWear eye protection and heavy clothing. S Extend your left arm and hold handlebar

grip with your left hand.

S Hold throttle grip with your right hand with finger on throttle trigger.

S Keep unit below waist level.

S Keep shoulder strap pad centered on your left shoulder and danger sign centered on your back.

S Maintain full weight of tool on your left shoulder.

S Without bending over, keep the blade or trimmer head near and parallel to the ground and not crowded into material being cut.


TRIMMER LINE ADVANCE 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 ON posi- tion.


The trimmer line will advance approximately 2 in. (5 cm) each time the bottom of the trimmer head is tapped on the ground with the engine running at full throttle.

The most efficient line length is the maximum length allowed by the line limiter.Always keep the shield in place when the tool is being oper- ated.

To advance line:

SOperate the engine at full throttle.

SHold the trimmer head parallel to and above

the grassy area.

STap the bottom of the trimmer head lightly on the ground one time. Approximately 2 in. (5 cm) of line will be advanced with each tap.

Always tap the trimmer head on a grassy area. Tapping on surfaces such as concrete or asphalt can cause excessive wear to the trimmer head.If the line is worn down to 2 inches (5 cm) or less, more than one tap will be required to obtain the most efficient line length.

CUTTING METHODS WARNING: Use only 0.080(2 mm) diameter line. Other sizes of line will not ad- vance properly and can cause serious injury. Do not use other materials such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury.


Trimming 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.

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.

TRIMMING -- Hold the bottom of the trimmer head about 3 in. (8 cm) above the ground and at an angle. Allow only the tip of the line to make contact. Do not force trimmer line into work area.


SCALPING -- The scalping technique removes unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 3 in. (8 cm) above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique in- creases line wear.
