5.5 Compressed air connection

To use the vacuum chuck and the blow gun, the machine
must be connected to compressed air.
Compressed air supply
Connect blow gun hose (A, Fig 13) to the T-connector.
Connect your incoming air supply to the quick connect coupler
(B).
Attach vacuum adaptor (C) to hose (D).
Push adaptor into the spindle.
Install support bracket (E, Fig 14) with knurled screw. This
prevents adaptor from backing out during spindle rotation.
Rotate the switch (H, Fig 15) to activate or to deactivate the
vacuum air flow.
The vacuum gauge (R) shows the vacuum pressure achieved
in cmHg (76cmHg=1bar).
Caution:
Continuous compressed air supply must be assured for
vacuum chucking.
The chucking surface must be big enough to ensure sufficient
vacuum forces.
The chucking surface must be flat
The work piece must be hermetic and thick enough to avoid
air leakage and pressure loss.
If reversing spindle rotation, make sure vacuum chuck is
secured with the set screws.

Turn the knob (K) to the desired RPM.
There are 3 speed ranges, offering
-"speed" H (high range 0-3500 rpm)
-"general use" M (medium 0-2000 rpm)
- "torque" L (low range 0-910 rpm).
The RPM Readout shows the spindle speed
Use the switch (J) to reverse the spindle direction.
