Operation; Maintenance - Makita UH4570 Instruction Manual

CAUTION:
• Do not force the opening of the holder. Failure to do so
may cause deflection and damage to it.
Arm cord hook (Accessory)
CAUTION:
• Do not attach the holder of arm cord hook to other than
the extension cord. Do not attach it in a position closer
to the tool beyond the hook complete hooks. Failure to
do so may cause an accident or personal injury.
• Attach firmly one hook of the hook complete to the
tool's cord and the other hook of hook complete to the
extension cord. Working with the tool with a sole hook
only attached may cause an accident and injury.
Using the arm cord hook helps to minimize a risk of
cutting off the extension cord unexpectedly caused by the
loose extension cord. (Fig. 8)
Attach firmly the arm cord hook placing around your arm
and pass the extension cord through the holder. The
length of the arm cord hook band is adjustable.
NOTE:
• Do not pass the extension cord through the band.
• Do not force the opening of the holder. Failure to do so
may cause deflection and damage to it.
• Using the arm cord hook together with the waist cord
hook is more helpful.

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.
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. (Fig. 9)
CAUTION:
• Do not cut off dead trees or similar hard objects.
Failure to do so may damage the tool.
Hold the trimmer with both hands pull the switch trigger A
or B and move it in front of your body. (Fig. 10)
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. 11 & 12)
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. 13)
Attaching the chip receiver (accessory) on the tool when
trimming the hedge straight can avoid cut off leaves' being
thrown away. (Fig. 14)
To cut a hedge side evenly, it helps to cut from the bottom
upwards. (Fig. 15)
Trim boxwood or rhododendron from the base toward the
top for a nice appearance and good job. (Fig. 16)
Installing or removing chip receiver
(accessory)
CAUTION:
• Always be sure that the tool is switched off and
unplugged 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. 17)
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. 18)
At this time, the chip receiver needs to be installed so that
its hooks fit into grooves in the shear blade unit. (Fig. 19)
To remove the chip receiver, press its lever on both sides
so that the hooks are unlocked. (Fig. 20)
CAUTION:
• The blade cover (standard equipment) cannot be
installed on the tool with the chip receiver being
installed. Before carrying or storing, uninstall the chip
receiver and then install the blade cover to avoid blade
exposure.
NOTE:
• Check the chip receiver for secure installment before
use.
• Never try to uninstall the chip receiver by an excessive
force with its hooks locked in the blade unit grooves.
Using the excessive force may damage it.
