OPERATION

WARNING:
Keep hands away from shear
blades.
CAUTION:
Avoid operating the tool in very
hot weather as much as practicable. When operat-
ing the tool, be careful of your physical condition.
CAUTION:
Be careful not to accidentally
contact a metal fence or other hard objects while
trimming. The shear blades may break and cause
an injury.
CAUTION:
Be careful not to allow the shear
blades to contact the ground. The tool may recoil
and cause an injury.
CAUTION:
Overreaching with a hedge trim-
mer, particularly from a ladder, is extremely
dangerous. Do not work while standing on 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.25: (1) Cutting height (2) 10 cm
NOTICE:
Do not cut down dead trees or similar
hard objects. Doing so may damage the tool.
NOTICE:
Do not trim the grass or weeds while
using the shear blades. The shear blades may
become tangled in the grass or weeds.
Hold the tool with both hands, press the switch lever
and pull the switch trigger while pressing the lock-off
lever, and then move it forward.
► Fig.26
For basic operation, tilt the shear blades toward the
trimming direction and move it calmly and slowly at the
speed rate of 3 to 4 seconds per meter.
► Fig.27
To cut a hedge top evenly, tie a string at the desired
height and trim along it.
► Fig.28
If the chip receiver is attached to the shear blades, it
gathers discarded leaves and makes clean-up after-
ward much easier.
► Fig.29
To cut a hedge side evenly, cut from the bottom to top.
► Fig.30
When trimming to make a round shape (trimming box-
wood or rhododendron, etc.), trim from the root to the
top for a beautiful finish.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed before
attempting to perform inspection or maintenance.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
Cleaning the tool
Clean the tool by wiping off dust with a dry cloth or one
dipped in soapy water and wrung out.
NOTICE:
Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks may result.
Shear blade maintenance
Before the operation or once per hour during operation,
apply low-viscosity oil (machine oil, or spray-type lubri-
cating oil) to the shear blades.
► Fig.32
After operation, remove dust from both sides of the
shear blades with a wired brush, wipe it off with a cloth
and then apply low-viscosity oil (machine oil, or spray-
type lubricating oil) to the shear blades.
► Fig.33
NOTICE:
Do not wash the shear blades in water.
Doing so may cause rust or damage to the tool.
NOTICE:
Dirt and corrosion cause excessive blade
friction and shorten the operating time per battery charge.
Storage
The hook hole in the tool bottom is convenient for hang-
ing the tool from a nail or screw on the wall.
Attach the blade cover to the shear blades so that the blades
are not exposed. Store the tool out of the reach of children.
Store the tool in a place not exposed to moisture or rain.

Grinding the shear blades
NOTICE:
If the shear blades have considerably
deformed by grinding, replace the shear blades
with new ones.
1. Install the battery cartridge to the tool.
2.
Turn on and start the tool so that the upper blade
and lower blade are positioned alternately.
► Fig.35
3. Turn off the tool and remove the battery cartridge from the tool.
4. Remove the screw, and then remove the branch catcher.

5. Set the angle of a file to 45° (for UH004G/UH005G/
UH008G/UH009G) or 50° (for UH006G/UH007G), and
grind the upper blade from 3 directions with the file.
