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.

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.

When trimming to make a round shape (trimming box-

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.
