Overheat protection for tool/battery
When the tool/battery is overheated, the tool stops
automatically without any indication. The tool does not
start even if pulling the switch trigger. In this situation, let
the tool/battery cool before turning the tool on again.
NOTE:
The battery overheat protection works only with a battery
cartridge with a star marking. (Fig. 2)
Overdischarge protection (Fig. 3)
When the remaining battery capacity gets low, the battery
indicator blinks on the applicable battery side. By further
use, the tool stops and the battery indicator lights up
about 10 seconds. In this situation, charge the battery
cartridge.
Handle mounting positions
CAUTION:
• Always make sure that the handle is locked in the
desired position before operation. (Fig. 4)
Depending on the operations, you can set the angle of the
handle either 45° or 90° position on left or right. To turn
the handle, pull the knob and turn the handle as shown in
the figure. The handle is locked in 45° position. To turn the
handle to 90° position, pull the knob again and turn the
handle more.
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. 5)
For your safety, this tool has a dual switching system. To
turn on the tool, press the lock-off button and press the
switch trigger A and B. To turn off the switch, release
either one of the switch triggers. The tool only starts when
pulling the both switch triggers.
Speed change (Fig. 6)
The strokes per minute can be adjusted just by turning the
adjusting dial. This can be done even while the tool is
running. The dial is marked 1 (lowest speed) to 6 (full
speed).
Refer to the table below for the relationship between the
number settings on the adjusting dial and the strokes per
minute.

• The strokes per minute vary by the conditions of
battery cartridge and shear blades.
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. 7)
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.
CAUTION:
• Do not cut off dead trees or similar hard objects.
Failure to do so may damage the tool. (Fig. 8)
Hold the trimmer with both hands and pull the switch
trigger A or B and then move it in front of your body.
(Fig. 9)
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. 10)
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. 11)
Attaching the chip receiver (optional accessory) on the
tool when trimming the hedge straight can avoid cut off
leaves' being thrown away. (Fig. 12)
Rotate the handle for your easy handling before
operation. Refer to the section titled "Handle mounting
positions".
To cut a hedge side evenly, it helps to cut from the bottom
upwards. (Fig. 13)
Trim boxwood or rhododendron from the base toward the
top for a nice appearance and good job.
Installing or removing chip receiver
(optional accessory)
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before installing or
removing chip receiver.
NOTE:
• When replacing the chip receiver, always wear gloves
so that hands and face does not directly contact the
blade. Failure to do so may cause personal injury.
• Always be sure to remove the blade cover before

installing the chip receiver.
• The chip receiver receives cut-off leaves and alleviates
collecting thrown-away leaves. This can be installed on
either side of the tool. (Fig. 14)
Press the chip receiver on the shear blades so that its slits
overlap with the nuts on the shear blades. At this time,
make sure that the chip receiver does not contact branch
catcher at the top of the shear blades. (Fig. 15)
At this time, the chip receiver needs to be installed so that
its hooks fit into grooves in the shear blade unit. (Fig. 16)
To remove the chip receiver, press its lever on both sides
so that the hooks are unlocked. (Fig. 17)
