NOTE:
• Some items in the list may be included in the tool
package as standard accessories. They may differ
from country to country.
Installing or removing hedge shear
blades
CAUTION:
• Before installing or removing shear blades, always be
sure that the tool is switched off and the battery
cartridge is removed.
• When replacing the shear blades, always wear gloves
without removing blade cover so that hands and face
do not directly contact the blade. Failure to do so may
cause personal injury.
NOTE:
• Do not wipe off grease from the gear and crank. Failure
to do so may cause damage to the tool.
• For specific way of removing and installing shear
blades refer to the reverse of a package for accessory
shear blades.
Installing the hedge shear blades (Fig. 28)
Prepare the crank, the undercover and new shear blades.
(Fig. 15)
Adjust the three pin position so that these three pins are
aligned with the basic alignment line on the tool housing.
(Fig. 16)
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. 29)
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. 30)
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. 31)
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. 32)
Tighten two screws with a coin firmly. (Fig. 33)
Place the undercover so that the symbol
undercover is aligned with the symbol Δ on the locking
lever. (Fig. 34)
Press the undercover down and with the undercover
pressed down turn the undercover clockwise until the
on the label is aligned with the symbol Δ on the
symbol
locking lever (the undercover is completely locked.).
(Fig. 21)
At this time, make sure that the locking lever fits in the
groove in the undercover.
CAUTION:
• Never use the tool without installing the undercover on
it.
Remove the blade cover and then turn on the tool to
check it for proper movement.
NOTE:
• When the shear blades do not operate properly, there
is a poor fit between the blades and crank. Redo from
the beginning.
Removing the hedge shear blades
(Fig. 35)
CAUTION:
• Install the blade cover before removing or installing the
shear blades.
Reverse the tool. (Fig. 36)
To remove the shear blades, press the locking lever and
with the locking lever pressed turn the undercover
counterclockwise until the symbol
aligned with the symbol Δ on the locking lever. (Fig. 37)
Take out the undercover from the tool. (Fig. 38)
Loosen two screws with a coin and remove the shear
blades.
NOTE:
• Do not remove the screws. Without removing the
screws loosened, shear blades can be removed.
(Fig. 39)
Remove the crank from the shear blades.
NOTE:
• The crank may remain in the tool. (Fig. 40)
NOTE:
• In the 2-way usage, the removed grass shear blades
need to be sheared in the blade storage case and
stored for future use.
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. 41)
Do not attempt to cut branches thicker than 10 mm
diameter with this trimmer. These should first be cut with
on the
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. 42)
Hold the trimmer with one hand, depress the lock-off
button and pull the switch trigger and then move it in front
of your body. (Fig. 43)
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. 44)
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. 45)
