Minimum angle adjustment screw
Disassembly
Warning
Improper adjustment of the minimum displacement limiter can result in undesirable or unsafe speed
conditions. Consult with the original equipment manufacturer or your Sauer-Danfoss representative
before changing the minimum displacement setting. After adjustment, verify the minimum displacement
setting by testing: using an appropriate test apparatus.
1. Thoroughly clean all external surfaces before disassembly.
2. Remove the tamper resistant cap (Q120) covering the adjustment screw.
3. Discard the cap. Removing the cap destroys the locking device.
4. Measure the length of the screw (Y10) to assure correct reinstallation.
