ADJUSTMENTS
Adjust PowerHook Operating Range
1. Adjust the upper vertical limit of PowerHook
operating range if necessary.
A. Locate the hook cylinder assembly and the
hold down cylinder assembly. The length of
the threaded eye on the hold down cylinder will
determine the upper vertical limit of the hook
movement.
B. Disconnect the Hydraulic hose from the hold
down cylinder. Cap off the open fittings to
prevent fluid loss and to prevent contamination
from entering the system.
C. Remove the keepers from the hold down
cylinder trunnion.
D. Lift up on the hook cylinder. This will allow the
hold down cylinder to exit the trunnion.
E. Support hook cylinder, loosen the jam nut
that is on the threaded eye of the hold down
cylinder.
