3.2.1 Adjustment of hydraulic limit switch
The K90 forward tipping box rotator is protected against unintended opening of the upper clamp during tipping by
means of a hydraulic limit switch. See figure 3.2.3. If the upper clamp fails to open in its horizontal position, check
whether the limit switch on the tipping frame is operated. If not, the limit switch stop must be raised to the point
where the switch does operate.
1.
Check that the tipping frame is horizontal and resting on its bump rubbers.
2.
Loosen the adjusting tube bolt and locknut. See figure 3.2.1.
3.
Bring the stop to the correct height, so that it comes up against the handle of the hydraulic switch. Check
that the limit switch operates.
4.
Securely retighten the bolt and locknut in the adjusting tube.
5.
Check the machine for proper operation.
Please contact your dealer for any further concerns you may have. He will be pleased to assist.
Always use original WIFO parts for replacement in order to comply with the warranty terms and conditions.
