Application
Grinding, polishing etc. Use only bits with a suitable shaft, 3 or 6 mm that are de-
signed for the applicable rpm.
Operating guidelines
Compressed air
Always install a pressure regulator before the tool, since the best effect is
achieved using the right air pressure. Maximum air pressure is 6.2 bar.
Air supply
Use a hose with an inner diameter of at least Ø 8 mm from the main air supply to
the tool. Compressed air contains water that will condense in pipes and hoses,
therefore a filter with a water separator should be installed before the tool. An oil
mister installed in front of the tool will prolong its life.
Pneumatic hose
Pneumatic tools are sensitive to damp and contamination. Flush the hose with
compressed air before installing it between the main line and the tool. A long,
narrow hose may cause pressure loss, so try to keep the length of the hose as
short as possible.
Accessories
Use only tools that are designed for pneumatic equipment and can handle the rpm
that the machine uses.
Safety equipment
Always use safety goggles, ear defenders, and protective gloves when the
machine is in use and use respiratory protection when needed.
Ventilation
Ensure that the work area is well ventilated.
Pressure loss
Always release the control handle when pressure loss occurs to prevent accidental
start when the pressure returns.
Air pressure control handle (ON/OFF)
The control handle is placed on the side of the main handle. Press the handle
to start the grinder. The spindle will stop after a few seconds when the handle
is released. Turn off the air supply and hang up the tool after use to prevent
accidental start.
Adjusting the rpm
The rpm can be adjusted using the screw on the machine housing. Use a suitable
screwdriver and turn the screw to “LO” (lower rpm) or “HI” (higher rpm).
