Repair or replace magnet
Check, re-calibrate support cylinder (call service agent)
Replace variable displacement pump completely
Fault Machine accelerates and decelerates sluggishly, too little propulsive power
Cause • Engine performance not to standard
• Breaks have not released fully
• No tank pressurization
• Suction filter clogged
• Oil loss in rotary joint
• Charge pump sucking up air
• Insufficient charge or supply pressure
• Pressure relief valve of charge circuit dirty or damaged
• Insufficient high-pressure
• Variable displacement pump does not open fully
• Adjusting motor not adjusting
• Internal damage to variable displacement pump or variable displacement motor
Corrective
measure
Check diesel engine
Check, remedy damage
Check tank seal, replace
Replace filter
Re-seal rotary joint
Check, re-seal
Check pressure, adjust
Check, re-adjust or replace
Check high-pressure (pressure cut-off); if necessary, re-adjust
Insufficient pilot pressure. Mechanical damage to pump adjustment. Check,
re-adjust or repair
Adjustment start is set too high. Mechanical damage on controller or
adjustment. Adjust or call service agent
Replace unit
Fault Machine working too slowly, hydraulic oil overheating
Cause • Main pressure relief valve set too low or defective
