Troubleshooting, eliminating faults

The basic setting of the spindle assembly is not correct
If the vice is open up to the stop, two grooves must be visible within the spindle
area (pos. 10) and the scraper (pos. 120).
Should no, one or three groove(s) be visible in this position, the carriage was turned during
assembly respectively disassembly and has to be reset since otherwise the scraper can suffer
damage or the closing disc (pos. 70) in the fixed carriage (pos. 30) will be pushed out.
The listed clamping range can then also no longer be guaranteed.
Proceed as described in Section 7 to restore the basic setting.
The spindle does not decouple
Clean the guide and the spindle as the clamping device is soiled and causes too much friction
so that the force increase is triggered before contact is made with the workpiece and no
tension is applied.
When turning back, the unit does not couple into the home position
(e.g. due to a very deep grip profile)
Restrain the outer spindle manually and turn the inner spindle back until it engages.
The spindle does not engage when opening
If the outer spindle is not coupled, it rotates with the inner spindle.
Then is the O-ring of the spindle brake is worn and must be replaced in accordance with
Section 6.1 Removal, changing the spindle brake O-ring.
Unable to install fixed jaw
The groove in the tool body (pos. 40) and fixed carriage (pos. 30) are misaligned
and the carriage cannot be moved into the correct position.
The threaded pin (pos. 90) may have been excessively clamped in the tool body. However, it is
merely intended for rough positioning and as an assembly aid. It must only be positioned
loosely in the recess and it must be possible to move it slightly.
The correct position of the fixed carriage (pos. 30) must be defined exclusively by the
wedge of the fixed jaw.
