Reverse the tool. (Fig. 37)
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  on the locking lever. (Fig. 38)
Take out the undercover from the tool. (Fig. 39)
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. 40)
Remove the crank from the shear blades.
NOTE:
• The crank may remain in the tool. (Fig. 41)
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. 42)
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. 43)
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. 44)
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. 45)
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. 46)
Attaching the chip receiver (optional accessory) on the
tool when trimming the hedge straight can avoid cut off
leaves' being thrown away. (Fig. 47)
To cut a hedge side evenly, it helps to cut from the bottom
upwards. (Fig. 48)
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.
• When replacing the chip receiver, always be careful not
to contact the shear blades.
• The chip receiver receives cut-off leaves and alleviates
collecting thrown-away leaves. This can be installed on
either side of the tool. (Fig. 49)
Place the chip receiver on the shear blades so that its slits
overlap with the screws on the shear blades and secure it
using two clamping nuts.
To remove the chip receiver, loosen and remove the two
clamping nuts and then take it out.
Storage (Fig. 50)
The hook hole in the tool bottom is convenient for hanging
the tool from a nail or screw on the wall.
Put the blade cover on the shear blades so that the blades
are not exposed. Store the tool out of the reach of children
carefully.
Store the tool in the place not exposed to water and rain.
Noise
The typical A-weighted noise level determined according
to IEC60335:
Model DUM166
Sound pressure level (L
Uncertainty (K): 2.5 dB (A)
The noise level under working may exceed 80 dB (A).
Model DUM168
Sound pressure level (L
Uncertainty (K): 2.5 dB (A)
The noise level under working may exceed 80 dB (A).
Wear ear protection.
Vibration
The vibration total value (tri-axial vector sum) determined
according to IEC60335:
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration emission value has been
measured in accordance with the standard test method
and may be used for comparing one tool with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the power
tool can differ from the declared emission value
depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of exposure in
the actual conditions of use (taking account of all parts
of the operating cycle such as the times when the tool
is switched off and when it is running idle in addition to
the trigger time).
