Adjusting the shaft length
WARNING:
• Before adjusting the shaft length, release the switch
trigger and remove the battery cartridge from the string
trimmer. Failure to release the trigger and removing the
battery cartridge may cause a personal injury.
To adjust the length of the shaft, turn the grip
counterclockwise until the shaft is unlocked and pull out or
push in to the desired length. (Fig. 8)
Nylon cutting head
NOTICE:
• The bump feed will not operate properly if the nylon
cutting head is not rotating.
The nylon cutting head is a single string trimmer head
provided with a bump & feed mechanism.
To cause the nylon cord to feed out, the cutting head
should be bumped against the ground while the tool is
running. As the nylon cord is feeding out it will
automatically be cut to the proper length by the cutter on
the guard. (Fig. 9)
NOTE:
• If the nylon cord does not feed out while bumping the
head, rewind/replace the nylon cord by following the
procedures described under "Installing or removing the
nylon cutting head" and "Winding a new nylon cord on
the spool."
• Do not bump the tool to the concrete or asphalt
surface. Bumping to this kind of objects may cause the
tool damage.
ASSEMBLY
WARNING:
• Always be sure that the tool is switched off and
battery cartridge is removed before carrying out
any work on the tool. Failure to switch off and remove
the battery cartridge may result in serious personal
injury from accidental start-up.
• Never start the tool unless it is completely
assembled. Operation of the tool in a partially
assembled state may result in serious personal injury
from accidental start-up.
Installing the front grip (Fig. 10)
Put the front grip on the front grip holder and secure it with
a hex bolt and the clamping nut provided with the string
trimmer as shown in the figure. At this time, the hex bolt
needs to be installed from the side in which the hex bolt
lock port is located and the clamping nut needs to be
installed from the opposite side.
NOTE:
• The front grip has a edge-to-edge cut slit in its
mounting area. Using this slit allows you to easily install
the front grip on the front grip holder.
The front grip angle is adjustable. To adjust the front grip
angle, loosen the claming nut, set the front grip at an
proper angle according to your work and then tighten the
nut clockwise firmly.
Installing the guard
CAUTION:
• While installing the guard, be careful not to contact
the nylon cord cutter provided on the guard.
Contact with the cutter could result in personal injury.
Mount the guard by fitting it on to the motor housing so
that the nylon cord is not pinched between the guard and
the motor housing, and then secure it with two screws.
Before starting the trimmer, take away the cutter cover
from the cord cutter. (Fig. 11)
Installing or removing the nylon cutting
head
WARNING:
• Before installing or removing the nylon cutting
head (both spool cover and spool, and hereafter
called this way), make sure that the tool is switched
off and the battery cartridge is removed from the
tool. Failure to switch off the tool and remove the
battery cartridge may cause a personal injury.
CAUTION:
• While installing or removing the nylon cutting
head, be careful not to contact the nylon cord
cutter provided on the guard. Contact with the cutter
could result in personal injury.
To remove the nylon cutting head (spool and spool cover)
from the string trimmer, press in the latches forcefully on
both sides of the spool cover and raise it. (Fig. 12 & 13)
NOTICE:
• Make sure that the spring is installed inside the spool
holder.
To install a cord-newly-wound nylon cutting head (spool
and spool cover) on the string trimmer, align the nylon
cord eyehole with the notch of the nylon cutting head
installation port on the trimmer and then press in it until a
click is heard. (Fig. 14)
Winding a new nylon cord on the spool
Remove the spool from the spool cover and take off the
remaining used nylon cord from the spool. (Fig. 15)
Insert a nylon cord to the retainer shown in the figure.
(Fig. 16)
Wind it tightly flat around the spool in the direction of
arrow on the spool so that the wound nylon cord surface
appears uniform over the winding area. (Fig. 17)
Temporarily fix a nylon cord at the notch shown in the
figure. (Fig. 18)
Bring the nylon cord through the nylon cord eyehole in the
spool cover. (Fig. 19)
After installing the nylon cutting head, make sure that the
nylon cord comes out by pressing the spool and pulling
the nylon cord. (Fig. 20)
