MAINTENANCE

WARNING:
Before inspecting or maintaining
the equipment, switch off the motor and remove
the battery cartridge. Otherwise, the machine may
start unintentionally and result in serious injury.
WARNING:
When inspecting or maintaining
the equipment, always put it down. Assembling or
adjusting the equipment in an upright position may
result in serious injury.
WARNING:
Follow the warnings and precau-
tions in the chapter "SAFETY WARNINGS" and
the instruction manual of the power unit.
CAUTION:
Wear gloves when performing the
inspection or maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
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.29
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.30
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
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.
When storing the attachment separated from the power
unit, put the cap onto the end of the pipe.

5.
Tighten the bolt.
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.

3. Turn off the tool and remove the battery cartridge
from the tool.
4. Remove the screws and nut, and then remove the
tip guard from the shear blades.

5.
Set the angle of a file to 45°, and grind the upper
blade from 3 directions with the file.
► Fig.37: (1) File (2) 45°
CAUTION:
Before grinding the shear blades,
make sure that the tool is switched off and the
battery cartridge is removed from the tool.
6. Place the tool upside down, and then remove the
burrs from the shear blades with the dressing stone.
► Fig.38: 1. Dressing stone
7. Set the angle of the file to 45°, and grind the lower
blade from 3 directions with the file.
8. Return the tool to normal position, and then
