General maintenance

NOTE: Remember that regular maintenance will keep the wrecker in good condition,
extend its lifespan and reduce the risk of damage and breakage.
4.2.1 General wrecker maintenance
Description
Adjust the hydraulic pressure. See
Section 4.4.1 Adjusting the
hydraulic pressure (main relief).
Check the cable tensioner for all
winches. See Section 4.2.4 Winch
cable tensioner. Check the dial on
the right side of the wrecker. The
dial should indicate a pressure of
approximately 75 to 90 psi (5.2 to
6.2 bar) to maintain the correct
cable pressure.
Inspect the bolts on the chassis
mounting plates for damage and
make sure they are tight. Have an
NRC-authorized distributor inspect
the chassis mounting plates for
cracks or structural damage. See
Section 4.2.2 Mounting plates
maintenance.
Replace all the oil filters (pressure
and return filters).
Clean the inlet filters and test the
hydraulic fluid.
