Preparing Compressed Air (Setting the Regulator)
WARNING
Turn the air pressure adjustment knob slowly and carefully.
Otherwise, the machine may move suddenly, posing a risk of injury.
Pull up on the upper knob (The air pressure
adjustment knob).
Slowly turn the upper knob.
Push down on the upper knob.
Recommended Set Pressure
Shank diameter: Ø4 mm
Length: 40 to 55 mm
Pin diameter: 6 mm
Be sure to configure the regulator to 0.2 MPa or lower. Anything higher may result in a malfunction.
When supply of air starts, the air starts to flow
and the pressure drops. When the pressure has
dropped, adjust the regulator to have an appropri-
ate value again. (Air is supplied when the spindle
rotates or when the tool is replaced.)
