In this situation, the spindle sleeve gets blocked with the cylinder (900030...) and the high pressure isarnold not released when the handle is turned anti-clockwise. The clutch system does not work.
This can be due to 2 reasons:
- The handle has been turned too much to obtain high pressure.
- The jaws have been opened totally and the work-piece surpasses the clamping area inhibiting the jaw movement.
Solutions:
- To free the spindle, the deposit must be fixed with a wrench. A light anti-colckwise knock must then be made on the handle to release it from the cylinder. The handle is then turned to free the clutch (high pressure) system. A clicking sound will confirm this.
- The spindle does not release the clutch. The handle must be turned clockwise firmly. The jaw assembly will move forward. Once the jaw assembly is free and positioned half-way along the vice body, the deposit must be fixed as in the case above, applying light knock on the handle anti-clockwise and proceeding to turn the handle in order to free the clutch system (click).
