Tips for best trimming
results (Fig. 16)
 The correct angle for the cutting
attachment is parallel to the ground.
 This string trimmer allows you to
rest the bump knob on the ground
for operating more comfortably.
 Do not force the trimmer. Allow the
very tip of the line to do the cutting
(especially along walls). Cutting with
more than the tip will reduce cutting efciency and may overload the motor.
 The cutting height is determined by the distance of the cutting line from the lawn
surface.
 Grass over 200mm should be cut by working from top to the bottom in small
increments to avoid premature line wear or motor drag.
 Slowly move the trimmer into and out of the area being cut, maintaining the
trimmer at the desired cutting height. This can be either a forward backward or
side-to-side motion. Cutting shorter lengths produces best results.
 Trim only when grass and weeds are dry.
 Wire and picket fences can cause extra line wear or breakage. Stone and brick
walls, curbs, and wood may wear lines rapidly.
 Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can
easily be damaged by the lines.

ADJUSTING CUTTING LINE
LENGTH
The bump head allows the operator to
release more cutting line without stopping
the motor. As line becomes frayed or worn,
additional line can be released by lightly
tapping the bump knob on the ground
while operating the trimmer (Fig. 17).
NOTICE: Always keep the cutting line fully
extended. Line release becomes more
difcult as the cutting line becomes shorter.
WARNING: Do not remove or alter the line cutting blade assembly. Excessive
line length will cause the motor to overheat and may result in serious personal injury.
For best results, tap the bump knob on bare ground or hard soil. If line release is
attempted in tall grass, the motor may overheat. Always keep the cutting line fully
extended. Line release becomes more difcult as the cutting line becomes shorter.
WORKING WITH BUMP
PROTECTOR
The bump protector can limit the cutting
range of the cutting line and reduce the
risk of the rotating cutting line causing
damage (Fig. 18)
To use the bump protector, ip it down
from its stored position (Fig. 19).
WARNING: The bump head may
continue to rotate briey after you switch
off the string trimmer. Wait for the bump
head to come to a complete stop before
adjusting the bump protector. Do not
adjust it with your foot.
