HOLDING THE STRING TRIMMER
WARNING:
Dress properly to reduce the risk of injury when
operating this unit. Do not wear loose clothing or
jewellery. Wear eye protection. Wear heavy, long
pants, boots and well fitting gloves. Do not wear short
pants, sandals or go barefoot.
n Hold the string trimmer as shown. See Figure 9a. Right
arm is slightly bent, the right hand holding the rear handle.
Left arm is straight, the left hand holding the front handle.
The unit should be slightly below waist level.
n The string head on your string trimmer should be parallel
to the ground and should easily contact the material being
cut without the operator having to bend over. A simple shaft
adjustment accommodates most user's heights.
USING THE STRING TRIMMER ADVANCING LINE
n Your string trimmer is equipped with a string head, which
allows the operator to release more cutting line without
stopping the motor. As the line becomes worn or frayed,
additional line can be released by lightly tapping the string
head on the ground while operating the string trimmer at
full throttle. See Figure 10. For best results, tap the head
on bare ground or hard soil. If line release is attempted
in tall grass, the motor may overheat.
n Approximately 25.4 mm (1 inch) of cutting line is released
each time the head is tapped on the ground.
n Always keep the cutting line fully extended. If the string is
worn too short you may not be able to advance the string
by tapping the head on the ground. If this occurs, stop
the motor, remove the spool as described in the following
section, feed the cutting line through the opening in spool
housing and reassemble the spool to the string head.
CUTTING LINE
n This string trimmer is equipped with a string cut off blade on
the grass shield. See Figure 11. For best cutting, advance
line until it is trimmed to length by the string cut-off blade.
Advance line whenever you hear the motor running faster
than normal. This will maintain best performance and keep
the cutting line long enough to advance properly.
OPERATING TIPS
n Clear the area to be cut before each use. Remove all
objects such as rocks, broken glass, nails, wire, or string
which can be thrown or become entangled in the string
head.
n Keep the string trimmer tilted toward the area being cut.
Avoid digging into grass.
n Slowly move the string trimmer in and out of the area
being cut.
n Use the tip of line to do the cutting - do not force string
head into uncut grass.
ENGLISH (Original Instructions)
n Cut tall grass from the top down. This will prevent grass
from wrapping around the string head that may cause
damage from overheating. If grass or other debris
becomes wrapped around the string head, STOP THE
MOTOR by releasing the trigger and allow the string
head to stop spinning. Remove the battery pack and then
remove the grass or debris.
n Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly. Walk around trees and shrubs. Tree
bark, wood mouldings, siding, and fence posts can easily
be damaged by the line.
USING THE STRING TRIMMER FOR EDGING/VERTICAL
CUTTING
n For vertical cutting/edging pull the edging coupler (Fig. 1
– L) and rotate the motor housing (Fig.1 - E) 180 degree.
Release the edging coupler (Fig. 1 – L) which snaps into
the edging position easily.
n Flip the edging wire (Fig. 1 –M) down for the edging.
n Lift the trimmer by both handles and turn it into cutting/
edging position.(Fig.9.b)
WARNING:
When servicing use only identical replacement parts.
Use of any other parts can create a hazard or cause

cleaning plastic parts. Most plastics are susceptible
to damage from various types of commercial solvents
and may be damaged by their use. Use a clean cloth
to remove dirt, oil, grease, etcv.
CAUTION:
After switching off, the nylon line will continue to rotate
for a few more seconds.

the existing spool or installing a convenient prewound
spool.
