S For 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.

S For 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.

Trimming

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 .

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.

SWEEPING -- Thefanning action of the rotat-

ing linecan 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

S Blad e Thru s t 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.

S WHAT CAUSE S BLADE TH RUS T -- 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.

S WHEN BLADE THRUST OCCURS --

Blade Thrust can occur without warning if

the blade snags, stalls, or binds. This is

more likely to occur in areas where it is

difficult to see the material being cut. By

using the unit properly, the occurrence of

blade thrust will be reduced and the

operator will be less likely to lose control.

S Cut only grass, weeds, and woody brush up

to 1 cm in diameter with the weed blade. Do

not let the blade contact material it cannot cut

such as stumps, rocks, fences, metal, etc., or

clusters of hard, woody brush having a

diameter greater than 1 cm.

S Keep the blade sharp. A dull blade is more

likely to snag and thrust.

S Cut only at full throttle. The blade will have

maximum cutting power and is less likely to

bind or stall.

S “Feed” the blade deliberately and not too

rapidly. The blade can thrust away if it is fed

too rapidly.
