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.

011264

CAUTION:

• The speed adjusting dial can be turned only as far as 6

and back to 1. Do not force it past 6 or 1, or the speed

adjusting function may no longer work.

• 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)
