4.4.1

Adjusting the hydraulic pressure (main relief)

For the CSR50 and CSR65

The CSR50 and CSR65 have two hydraulic systems: one system for the left side of the wrecker,
and one for the right side. Each system has its own hydraulic pump and two hydraulic valves, all
inline. As a result, the available hydraulic pressure will be constrained by the element that is
providing the least pressure.

For each hydraulic system, the pressure must be adjusted to 3,000 psi (207 bar) for the CSR50,
and 3,500 psi (241 bar) for the CSR65. To adjust the pressure of each hydraulic system, you will
first need to increase the pressure of each valve to 3,100 psi for the CSR50 or 3,600 psi for the
CSR65. If you cannot reach this value by increasing the pressure of the valves, the pump
pressure is too low and also needs to be adjusted.

The hydraulic pumps are accessible from under the wrecker.
