FAULT

CAUSE

REMEDY

Air discharge capacity
too low.

Engine speed too low.

Check the air cylinder and air filter(s).

Blocked air cleaner.

Check the restriction indicators and replace the element(s) if necessary.

High pressure air escaping.

Check for leaks.

Incorrectly set regulation system.

Reset the regulation system. Refer to

REGULATION ADJUSTMENT

in the

MAINTENANCE

section of this

manual.

Compressor overheats.

Low oil level.

Top up the oil level and check for leaks.

Dirty or blocked oil cooler.

Clean the oil cooler fins.

Incorrect grade of oil.

Use Doosan recommended oil.

Defective bypass valve.

Check the operation of the element and replace if necessary.

Recirculation of cooling air.

Move the machine to avoid recirculation.

Reduced cooling air from fan.

Check the fan and the drive belts. Check for any obstruction inside the fan
cowl.

Excessive oil present
in the discharge air.

Blocked scavenge line.

Check the scavenge line, drop tube and orifice. Clean and replace.

Perforated separator element.

Replace the separator element.

Pressure in the system is too low.

Check the minimum pressure valve or sonic orifice.

Safety valve operates.

Operating pressure too high.

Check the setting and operation of the regulator valve piping.

Incorrect setting of the regulator.

Adjust the regulator.

Faulty regulator.

Replace the regulator.

Inlet valve set incorrectly.

Refer to

SPEED AND PRESSURE REGULATION ADJUSTMENT

in the

MAINTENANCE

section of this manual.

Loose pipe/hose connections.

Check all pipe/hose connections.

Faulty safety valve.

Check the relieving pressure. Replace the safety valve if faulty.

DO NOT

ATTEMPT A REPAIR.

Oil is forced back into
the air filter.

Incorrect stopping procedure used.

Always employ the correct stopping procedure. Close the discharge valve
and allow the machine to run on idle before stopping.

Faulty inlet valve.

Check for free operation of the inlet valve(s).

Machine goes to full
pressure when started.

Inlet valve set incorrectly.

Refer to

SPEED AND PRESSURE REGULATION ADJUSTMENT
