Installing the hedge shear blades (Fig. 27)
Prepare the crank, the undercover and new shear blades.
(Fig. 28)
Adjust the three pin position so that these three pins are
aligned with the basic alignment line on the tool housing.
(Fig. 29)
Fit the crank with its recessed part facing downward onto
the pins. At this time, apply a small amount of grease to
the periphery of the crank using grease that the shear
blades as optional accessory are provided with or that
remains inside gear housing. (Fig. 30)
Overlap the oval hole in the upper blade with that in the
lower one. Move the shear blades so that the hole in the
base plate of shear blades are positioned in the center of
these overlapped oval holes. (Fig. 31)
Take out the blade cover from the old shear blades and fit
it onto the new ones for easy handling during the
replacement of blades. (Fig. 32)
Turn the shear blades upside down and install it so that
pin on the tool fit in the hole in the shear blades. Fit the
bent part of the base plate of the shear blades to the
groove in the tool housing. Then make sure that the base
plate of the shear blades is set in place. (Fig. 33)

At this time, make sure that the locking lever fits in the
groove in the undercover.

OPERATION
Refer to the Important Safety Instructions before
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.
• Also, be careful for the shear blade not to contact the
ground.
• Overreaching with a hedge trimmer, particularly from a
ladder, is extremely dangerous. Do not work from
anything wobbly or infirm. (Fig. 43)
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.
• Do not trim the grass or weeds while using hedge
shear blade. The shear blade may entangle the grass
or weeds. (Fig. 44)
Hold the trimmer with one hand, depress the lock-off
on the
button and pull the switch trigger and then move it in front
of your body. (Fig. 45)
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. 46)
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. 47)
Attaching the chip receiver (accessory) on the tool when
trimming the hedge straight can avoid cut off leaves' being
thrown away. (Fig. 48)
To cut a hedge side evenly, it helps to cut from the bottom
upwards. (Fig. 49)
Trim boxwood or rhododendron from the base toward the
top for a nice appearance and good job.
Installing or removing chip receiver
(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.
• When replacing the chip receiver, always be careful not
to contact the shear blades.
