Grinding The Shear Blades - Makita DUH604S Manual De Instrucciones

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 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.
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.
