CAUTION
Before performing any service or repair on hy-
draulic system components, relieve system
pressure to avoid injury from pressurized hy-
draulic oil. Stop the engine, remove key from the
ignition switch, rotate the steering wheel in both
directions, lower or support the bed and operate
other hydraulic accessories.

control valve to vehicle frame. Move steering valve (with
hydraulic hoses attached) away from vehicle frame.

hoses and valve fittings to prevent contamination and
leakage of hydraulic oil.
