Grease Lubrication - Makita UH013G Instruction Manual

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.37
After operation, remove dust from 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.38
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.
Remove the battery cartridge from the tool, and then
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.

3.
Turn off the tool and remove the battery cartridge
from the tool.
4. Set the angle of a file to 45°, and grind the upper
blade from 3 directions with the file.
► Fig.41: (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.
5.
Place the tool upside down, and then remove the
burrs from the shear blades with the dressing stone.

6. Set the angle of the file to 45°, and grind the lower
blade from 3 directions with the file.
7. Return the tool to normal position, and then
remove the burrs from the shear blades with the dress-
ing stone.
