Adjust Relief Cartridges
To avoid over clamping or slow sideshifting speed,
relief cartridges should be adjusted to ensure correct
settings. Check the nameplate and decal on the valve for
correct CLAMP hydraulic pressure settings.
NOTE 1: Clamp used for fork positioning requires no
CLAMP relief adjustment. Contact Cascade before making
any adjustments.
NOTE 2: External SS function has no relief adjustment.
Clamp Relief Adjustment
A
Confirm that TRUCK pressure delivered to the
attachment valve is within the range shown on the
attachment nameplate.

B
Install a 345 bar pressure gauge (with a No. 4 O-ring
fitting) to the valve TEST port (location varies).
C
From fully open, close arms at normal speed to clamp
a rigid load (or clamp force indicator). Release truck
handle and read pressure gauge.
D
