Using the adjustment screw located on the front of the valve, adjust the maximum pilot pressure
to 550 +/- 50
(see G in Figure 5-12).

:
The generated pilot pressure port and the main relief valve pressure port are the same.
12.
To adjust pressure in the main relief valve, install a 0
- 5000
psi pressure gauge on the inlet cover
port (see E in Figure 5-12).
13.
Activate the packer retract function until the packer reaches the end of its stroke.
14.
Adjust the main relief valve pressure to 2,500
psi
(See F in Figure 5-12).

INIMAX
™ vehicles use an extra valve stack to control the arm. This valve is of the proportional type,
meaning that the amount of flow coming out of it will be according to the position of the spool.
Warning!
Replace the 0
- 600
psi pressure gauge with a 0
- 5000
psi pressure gauge for step
