Conversion from clockwise rotation (as supplied) to anti-clockwise rotation:
1. Loosen the clamping element (K) of the adjusting screw one rotation.
2. Unscrew the adjusting screw 6 a few rotations.
3. Unscrew flow control screw aJ and the fastening screws (M) from the sub-base.
4. Using pliers, remove the retaining ring (S) on the shock absorber.
5. Fit the following:
– the shock absorber with the retaining ring in the adjacent hole
– the O-ring (P) / buffer (for DHTG-65) in the adjacent groove
– the distance piece (T) in the same hole (distance piece omitted for 2/3 index stations)
– the sub-base with the fastening screws and the flow control screw in reverse sequence
(tightening torque
6. Unscrew the fastening screws (N) on the stop plate.
7. Unscrew:
– both locking screws (O) on the rear of the stop plate to begin with,
– then screw them in again into the open holes (tightening torque
The open holes (R) or (L) in Fig. 14 determine the direction of rotation
(Holes (R) open: clockwise rotation).
8. Screw the fastening screws (N) on the stop plate again (tightening torque
The rotary indexing table remains pneumatically controlled as before.
9. Screw in the adjusting screw 6 until the desired cushioning is achieved
