Pump output flows to the steering control valve before reaching the lift valve so the steering circuit has priority .
Workman HD Series Page 9 − 13 Hydraulic System Raise and Lower Bed The hydraulic gear pump supplies flow for the steering circuit and for raising and lowering the bed. Pump output flows through the steering control valve and then to the lift valve for raising and lowering the bed (flow priority to the steering circuit).
Workman HD Series Page 9 − 14 Hydraulic System High Flow Hydraulic Circuit On Workman HDX and HDX−D vehicles that are equipped with the high flow hydraulics kit, a second gear pump is directly coupled to the standard gear pump.
Workman HD Series Page 9 − 15 Hydraulic System T roubleshooting Th e cause of an improperly functioning hydraulic system is best diagnosed with the use of proper testing equip- ment and a thorough understanding of the complete hy- draulic system. A hydraulic system with an excessive increase in heat or noise is a potential failure.
Workman HD Series Page 9 − 16 Hydraulic System Problem Possible Cause Bed does not lift or lifts very slowly . Excessive load in bed. Oil level in transaxle is low . Engine RPM is low . Incorrect oil in system (see oil recommendations in Operator ’s Manual).
Workman HD Series Page 9 − 17 Hydraulic System Problem Possible Cause Difficulty in connecting or discon- necting quick couplers. Hydraulic pressure is not relieved (coupler under pressure − engine running). Hydraulic lift valve is not in neutral (centered) position.
Workman HD Series Page 9 − 18 Hydraulic System T esting The most effective method for isolating problems in the hydraulic system is by using hydraulic test equipment such as pressure gauges and flow meters in the circuits during various operational checks (see Special T ools section in this Chapter).
Workman HD Series Page 9 − 19 Hydraulic System 7. T o minimize the possibility of damaging components when using tester with pressure and flow capabilities, completely open load valve in hydraulic tester before starting engine.
