With the engine running and the pump switch ON, increase the engine RPM to 1500 and
activate the Tailgate Closed function. Have a helper note the reading on the gauge.
3.
If an adjustment is required (system pressure is higher or lower than 2500/2750 psi, depending
on the truck model), locate the pressure relief valve screwed into the inlet section of the main
valve bank (see Figure 7
41).
4.
Loosen the locknut and using an Allen key, turn the screw clockwise to increase the system
pressure, counterclockwise to decrease.
5.
When the hydraulic pressure is properly set to 2500/2750 psi (depending on the truck model),
tighten the locknut and recheck.
6.
If the system pressure is correct, remove the gauge.
