b. OPERATING INSTRUCTION
At work
- Check to see that the workplace is in order and is appropriate for the work.
- Inspect for loose parts.
- Confirm the proper air pressure (0.4 to 0.65 MPa)
- Tighten all couplings securely so that they will not be loosened by vibration.
- Attach buffing material or paper by pressing it uniformly with the palm of hand to attach it
securely.

Valve lever

Skirt
Starting and stopping
- The tool starts when the valve lever is pressed lightly. It stops when the lever is
released.
- Operate the lever as the abrasive contacts the surface to be polished. When the tool is
transported, be sure to remove the air hose.
During use
- The tool can be adjusted continuously from low to high speed by the speed control.
Adjust it according to the work.
- Do not press it onto the surface to be polished with excess force. This does not
increase efficiency, but it shortens tool life.
Speed control
After use
- Apply spindle oil to the air supply opening and operate the tool at low speed. After use,
be sure to remove the air hose and store the tool in a safe, dry place.
