Hydraulic tank may be pressurized! Depress relief valve (2, Figure 40-2) and release hydraulic tank filler cap slowly to remove any internal pressure.
The system is controlled by an electric timer which signals solenoid valves to cause operation of a hydraulically operated grease pump. For the HD1500-5, these components (valves, pump, and reservoir/canister) are mounted on the right deck structure to the right of the hydraulic cabinet just above the right front suspension.
