3. AIR SUPPLY
3-1. Air Pressure
Adjust air pressure with the air regulator to the
appropriate level for the pneumatic tool used.
Air pressure that is too low will stop the tool from
operating at full capacity.
Air pressure that is too high may cause damage to
the tool.
3-2. Air Line
(Fig.1)
Use a 9.5 mm (3/8”) I.D. connecting hose between
the compressor and the tool.
Drained water, etc., if flown into the tool, could
cause tool failure. Install an air filter between the
compressor and the tool.

3-3. Lubrication
Install an oiler between the compressor and the tool.
Use the machine oil ISO VG-10. Failure to lubricate
as required may result in damage to the tool. Use of
oil that is too thick will reduce the performance of the
tool.
4. ATTACHMENTS
WARNING
Do not use any attachment for which the operating
speed is lower than the actual free speed of the
grinder.
The attachment mandrel shall be inserted to the
full depth of the gripping jaws of the grinder chuck.
4-1. Selecting Attachments
The maximum speed of an attachment is determined
by the factors listed below. Use attachments which
have a strength exceeding the speed of this tool.
(1) Shape and size of the attachment
(2) Size of the mandrel
(3) Overhang of the mandrel
(4) Wheel specification
4-2. Mounted Wheel attachment
WARNING
Be sure to dress the grinding face of the Mounted
Wheel before using it.
Refer to the table below when selecting Mounted
Wheels. When an unmarked Mounted Wheel is to
be used, refer to the manufacturer of the wheel and
select one which is safe.
