OPERATION

CAUTION:
If the nylon cutting head acciden-
tally impacts a rock or hard object during oper-
ation, stop the tool and inspect for any damage.
If the nylon cutting head is damaged, replace it
immediately. Use of a damaged cutting tool could
result in serious personal injury.
Adjusting the handle position
CAUTION:
Before adjusting the shaft length,
be sure to switch off the tool and remove the
battery cartridge from the tool. Failure to do so may
cause a personal injury.
Adjust the length of the shaft and the cutting angle so
that the nylon cutting head is flat to the ground when
you hold the handle with your right hand.

Cutting the grass
Hold the grass trimmer with both hands, and move the
grass trimmer from right to left slowly. Cut the grass a
few times from the top of the grass at the tip of the nylon
cord.
NOTICE:
Do not cut high grass at a time. Cutting
the high grass at a time near the root may cause the
nylon cutting head to be entangled by grass. This
may cause the motor overload, resulting in damage to
the grass trimmer.
NOTICE:
Use the grass trimmer without get-
ting the nylon cutting head into a contact with
the ground surface. Using the nylon cutting head
contacting the ground surface may cause the motor
under overload resulting in damage to the grass
trimmer.

NOTICE:
Do not force the trimmer in densely
growing grass.

NOTICE:
Do not use the trimmer as if you dig out
the ground.

Cutting the grass near tree, block,
brick, or stone
Hold and tilt the grass trimmer at a height where the
nylon cutting head does not touch the ground. Cut the
grass using the nylon cord tip like knocking the ground.
► Fig.23
NOTICE:
When cutting the grass, move the
grass trimmer around the tree or blocks so that
the nylon cord does not touch the tree or blocks.
It is recommended to keep the tool more than 5 cm
away from the tree or block. If the nylon cord touch
the tree or block, the nylon cord may be torn. If the
nylon cord is torn in the nylon cutting head, set the
nylon cord again referring to the replacement proce-
dure in this manual.
Using the grass trimmer as an edger
Using the grass trimmer as an edger is suitable for
cutting the grass growing along the bricks or blocks.
Open the lock lever, then extend the shaft to the max-
imum length, then rotate the motor housing 180°, and
then close the lock lever.
► Fig.24: 1. Lock lever 2. Motor housing
NOTE: You can also rotate the motor housing 180°
when you shorten the shaft to the minimum length.
Lift up the wire guard, and move the grass trimmer as
shown in the figure to cut the grass. You can cut the grass
efficiently by walking in parallel along the bricks or blocks.
