5. Problem solving
The pump does not supply oil:
• Pump oil release valve open
• Badly connected couplings
• Shortage of oil in tank
• Accumulation of dirt in the circuit
The pump does not reach maximum pressure:
• Safety valve on wrong setting
• Worn or damaged seals
The circuit gradually loses pressure:
• Worn or damaged oil release valve
• Air in the circuit
• Accumulation of dirt in the circuit
Oil leaks:
• Worn or damaged seals
• Badly connected couplings
The application remains pressurized:
• Oil release valve not fully open
• Accumulation of dirt in the hydraulic circuit
• Restrictions in the hose
