Operation - Makita DUH551 Instruction Manual

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.

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.

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.
NOTICE:
Do not attempt to cut branches thicker
than 10 mm in diameter with the tool. Cut branches
to 10 cm lower than the cutting height using branch
cutters before using the tool.
► Fig.7: (1) Cutting height (2) 10 cm
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: 1. Trimming direction 2. Hedge surface to be
trimmed 3. Tilt the blades.
As a basic operation, tilt the blades towards the trim-
ming 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.
