(50 ft), also pay attention to any animals in the
working vicinity. Otherwise stop using the tool.
2.
Before use always check that the tool is safe for
operation. Check the security of the cutting tool
and the guard and the switch trigger/lever for
easy and proper action. Check for clean and dry
handles and test the on/off function of the switch.
3. Check damaged parts before further use of
the tool. A guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting, and any other condition that may
affect its operation. A guard or other part that
is damaged should be properly repaired or
replaced by our authorized service center
unless indicated elsewhere in this manual.
4. Switch on the motor only when hands and feet
are away from the cutting tool.
5.
Before starting make sure that the cutting tool has no
contact with hard objects such as branches, stones
etc. as the cutting tool will revolve when starting.
6. Make sure there are no electrical cables, water
pipes, gas pipes etc. that could cause a hazard
if damaged by use of the tool.
Method of operation
1. Never operate the machine with damaged
guards or without the guards in place.
2. Only use the tool in good light and visibility.
During the winter season beware of slippery
or wet areas, ice and snow (risk of slipping).
Always ensure a safe footing.
3. Take care against injury to feet and hands from
the cutting tool.

CAUTION: Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
Battery protection system
The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
Overloaded:
The tool is operated in a manner that causes it to draw
an abnormally high current.
In this situation, turn the tool off and stop the application
that caused the tool to become overloaded. Then turn
the tool on to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before turning the tool
on again.
Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you turn the tool on, the motor runs
again but stops soon. In this situation, remove and
recharge the battery.
Indicating the remaining battery
capacity
Only for battery cartridges with the indicator

OPERATION
Cutting the grass
Hold the grass trimmer at the angle of about 50° to the
ground. 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 or with the blade.
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 or plastic blade to be entangled by
grass. This may cause the motor overload, resulting
in damage to the grass trimmer.
NOTICE: Use the grass trimmer without getting
the spool or plastic blade into a contact with the
ground surface. Using the spool or plastic blade
contacting the ground surface may cause the motor
under overload resulting in damage to the grass
trimmer.

13 ENGLISH
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
spool or blade does not touch the ground. Cut the grass
using the nylon cord tip or plastic blade like knocking
the ground.
NOTICE: When cutting the grass, move the
grass trimmer around the tree or blocks so that
the nylon cord or blade 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 or
blade touch the tree or block, the nylon cord may be
torn or the blade may wear out rapidly. If the nylon
cord is torn in the spool, set the nylon cord again
referring to the replacement procedure 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.
Pull down the wire guard and rotate the grass trimmer
180°.
