ENGLISH (Original instructions)
u
Remove the tape holding the cutting line to the spool
housing.
Operation
Warning! Always use proper eye protection.
Warning! Before you begin trimming, only use the appropriate
type of cutting line.
Note: inspect area to be trimmed and remove any wire, cord,
or string-like objects which could become entangled in the
rotating line or spool. Be particularly careful to avoid any wire
which might be bent outwardly into the path of the appliance,
such as barbs at the base of a chain link fence.
Switching on and off
u
To switch the appliance on, push the lock-off button (2),
and squeeze the trigger (1).
u
To switch the appliance off, release the trigger.
Operating the trimmer
u
With the unit on, angle unit and slowly swing the trimmer
side to side as shown in Figure J.
u
Maintain a cutting angle of 5° to 10° as shown in Figure
J1. Do not exceed 10° (Figure J2). Cut with the tip of the
line. To keep distance from hard surfaces use edge wheel
(9).
u
Maintain a minimum distance of 60 cm between the guard
and your feet as shown in Figure J3. To acheive this
distance adjust the overall height of the trimmer as shown
in Figure I.
Convert to edging mode
Warning! The wheeled edge guide should only be used when
in the edging mode.The trimmer can be used in trimming
mode or edging mode to trim overhanging grass along lawn
edges and flower beds. For edging, the trimmer head should
be in the position shown in Figure l. If it is not:
u
Remove the battery from the trimmer.
u
Grasp the flip-to-edge collar (7) and push down as
shown in part 1 of Figure K.
u
Rotate the flip-to-edge collar 180° counterclockwise as
shown in part 2, until the handle snaps back into the
upper half of the trimmer.
u
To return to trimming position, pull the flip-to-edge collar
down and rotate the head clockwise back to its original
position.
Note: You will experience faster than normal cutting line wear
if the trimmer line is positioned directly over the sidewalk or
abrasive surface.
Edging
Warning! When being used as an Edger, stones, pieces of
metal and other objects can be thrown out at high speed by
the line. The trimmer and guard are designed to reduce the
danger. However, MAKE SURE that other persons and pets
are at least 30m away. Optimum cutting results are achieved
on edges deeper than 50 mm.
u
Do not use this trimmer to create trenches.
u
Using the edging wheel (9), guide the trimmer as shown in
Figure l.
u
Position the edging wheel on the edge of the sidewalk or
abrasive surface so the cutting line is over the grass or dirt
area to be edged.
u
To make a closer cut, slightly tilt the trimmer.
Speed control & runtime extension mode
This string trimmer gives you the choice to operate at a
more efficient speed to extend the runtime for larger jobs, or
accelerate the trimmer speed for high-performance cutting
(Figure M).
u
To extend runtime, pull the speed-control switch (4) back
toward the battery (12) into position #1. This mode is best
for larger projects that require more time to complete.
u
To accelerate the trimmer, push the speed-control switch
forward toward the trimmer head (8) into position #2.
This mode is best to cut through heavier growth and for
applications that need higher RPM.
Note: When in acceleration mode (#2), runtime will be de-
creased as compared to when trimmer is in extended runtime
mode (#1).
Helpful cutting tips
u
Use the tip of the string to do the cutting; do not force
string head into uncut grass. Use edge guide along such
things as fences, houses and flower beds for best prac-
tices.
u
Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
u
Do not allow spool cap to drag on ground or other sur-
faces.
u
In long growth cut from the top down and do not exceed
300 mm high.
u
Keep trimmer tilted toward the area being cut; this is the
best cutting area.
u
The trimmer cuts when passing the unit from the right to
left. This will avoid throwing debris at the operator.
u
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the string.
Cutting line / line feeding
Your trimmer uses 1.65 mm diameter, Round nylon line.
During use, the tips of the nylon lines will become frayed and
worn and the special self feeding spool will automatically feed
and trim a fresh length of line. Cutting line will wear faster and
require more feeding if the cutting or edging is done along
sidewalks or other abrasive surfaces or heavier weeds are
being cut. The advanced automatic line feeding mechanism
senses when more cutting line is needed and feeds and
trims the correct length of line whenever it’s required. Do not
bump unit on ground in attempt to feed line or for any other
purposes.
Clearing jams and tangled line (Figures N, O, P)
Warning! Remove the battery from the trimmer before making
any assembly, adjustments or changing accessories. Such
preventive safety measures reduce the risk of starting the
appliance accidentally. From time to time, especially when cut-
ting thick or stalky weeds, the line feeding hub may become
clogged with sap or other material and the line will become
jammed as a result. To clear the jam, follow the steps listed
below.
