Adjusting Hydraulic Pressure
A 0–4000
psi pressure gauge as well as a set of ball-end hex keys are required to adjust system pressure
Figure 5-10 Pressure gauge and ball-end hex key
The pressures of the various hydraulic functions of the Minimax are set up at the factory for optimal
performance. However, when you perform maintenance work on the hydraulic system of the truck,
you may need to adjust the hydraulic pressure for a number of reasons. For more information, see

INIMAX
™vehicles is equipped with an electro-hydraulic body control valve to power body hydraulic
functions, including the tailgate, the packer, and the crusher panel, if installed.
To adjust the pressure:
1.
Start the engine and engage the hydraulic system.
2.
Install a 0–4000
psi pressure gauge on the quick-connect coupler located on the hydraulic valve.
Warning!
Make sure that the ball valve on the suction line is completely open before starting the
engine. Failure to do so may damage the hydraulic system.
