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 minimum line wear by not crowding the line into the cutting area. The right and wrong ways are shown below.

Scalping

MOWING -- Your trimmer is ideal for mowing in places conventional lawn mowers cannot reach. In the mowing position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool.

Mowing

SThe 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 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.

8 cm above ground

SCALPING -- The scalping technique re- moves unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 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 increases line wear.

SWEEPING -- The fanning action of the rotat- ing line can be used to blow away loose debris from an area. Keep the line parallel to and above the area surface and swing the tool from side to side.

OPERATING INSTRUCTIONS FOR USE WITH WEED BLADE

SBlade Thrust is a reaction that only occurs when using a bladed unit. This reaction can cause serious injury such as amputation. Carefully study this section. It is important that you understand what causes blade thrust, how you can reduce the chance of its

occurring, and how you can remain in control of unit if blade thrust occurs.

SWHAT CAUSES BLADE THRUST --Blade Thrust can occur when the spinning blade contacts an object that it does not cut. This contact causes the blade to stop for an instant and then suddenly move or “thrust” away from the object that was hit. The “thrusting” reaction can be violent enough to cause the operator to be propelled in any direction and lose control of the unit. The uncontrolled unit can cause serious injury if the blade contacts the operator or others.
