Installing or removing battery cartridge
CAUTION:
• Hold the tool and the battery cartridge firmly when
installing or removing battery cartridge. Failure to
hold the tool and the battery cartridge firmly may cause
them to slip off your hands and result in damage to the
tool and battery cartridge and a personal injury. (Fig. 1)
• Always switch off the tool before installing or removing
of the battery cartridge.
• To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
• To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red indicator
on the upper side of the button, it is not locked
completely. Install it fully until the red indicator cannot
be seen. If not, it may accidentally fall out of the tool,
causing injury to you or someone around you.
Do not use force when installing the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Battery protection system (Lithium-ion
battery with star marking) (Fig. 2)
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool 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.
Indication lamp
The lamp blinks in red
The lamp lights up in red.
(Note 1)
The lamp lights up in red.
(Note 1)
Note 1: The time at which the indication lamp lights up varies by the temperature around the work area and the battery
cartridge conditions.

OPERATION
CAUTION:
• Be careful not to accidentally contact a metal fence or
other hard objects while trimming. The blade will break
and may cause serious injury.
• Overreaching with a hedge trimmer, particularly from a
ladder, is extremely dangerous. Do not work from
anything wobbly or infirm. (Fig. 5)
Do not attempt to cut branches thicker than 10 mm
diameter with this trimmer. These should first be cut with
shears down to the hedge trimming level.

Status
This indicates the appropriate time to
replace the battery cartridge when the
battery power becomes low.
This function works when the battery power
is almost used up. At this time, tool stops
immediately.
Autostop due to overload
In this situation, release the trigger switch on the tool
and stop the application that caused the tool to
become overloaded. Then pull the trigger switch
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
trigger switch again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and
recharge the battery.
Switch action
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released. (Fig. 3)
For your safety, this tool is equipped with a dual switching
system. To turn on the tool, press the lock-off button and
triggers A and B. Release either one of the two pressed
triggers to turn off. The sequence of switching is
unimportant as the tool only starts when both switches are
activated.
Indication lamp (Fig. 4)
Running the tool allows the indication lamp to show the
battery cartridge capacity status.
When the tool is also overloaded and has stopped during
operation, the lamp lights up in red.
Refer to the following table for the status and action to be
taken for the indication lamp.
Recharge the battery cartridge as soon
as possible.
Recharge the battery cartridge.
Turn off the tool.
CAUTION:
• Do not cut off dead trees or similar hard objects.
Failure to do so may damage the tool. (Fig. 6)
Hold the trimmer with both hands and pull the switch
trigger A or B and then move it in front of your body.
(Fig. 7)
As a basic operation, tilt the blades towards the trimming
direction and move it calmly and slowly at the speed rate
of 3 - 4 seconds per meter. (Fig. 8)
To cut a hedge top evenly, it helps to tie a string at the
desired hedge height and to trim along it, using it as a
reference line. (Fig. 9)
