ParaLift wear bushing replacement
The ParaLift is used to raise and lower the boom height to suit the terrain. However, with AutoTerrain, small adjustments are
being made continuously. Greasing the ParaLift pivot points on a regular basis will prolong the life of the wear bushings.
Inspect and replace the wear bushings before they are worn through.
1. Unfold the booms to working position.
2. Lift the boom center frame with a lifting device and support it
until the load is taken off the parallelogram arms.
3. Remove bolt (A), pull out pin (B) at one of the upper
parallelogram arms and replace the wear bushings.
4. Replace the pin (B) and bolt (A).
5. Repeat this on the other upper arm.
6. The lower arms must be disconnected simultaneously.
7. Grease all grease nipples.
8. Remove the lifting gear.
