TROUBLE SHOOTING CHART

IMPORTANT

1. Any remedial work that may be required must be carried out by a qualified engineer.

2. Switch off the engine before removing any parts from the compressor.

3. Drain the Air Receiver before dismantling any part of the compressor unit's pressure system.

4. If your compressor develops a fault do not use until the fault has been rectified.

5. For troubleshooting the engine, refer to the engine manual.

PP9ND

Fully open the receiver drain cock, located between the wheels.

Start the engine,

according to the

instructions contained in

the engine service

manual, and allow to

run for 10 minutes.

After a ten minute

period, close the drain

cock then ensure both

air outlet slding valves

are pushed fully INWARDS

to close the outlets.

Pressure will build up in the

receiver and eventually

the air governor will

operate so that the engine

runs off load. The pressure

registered on the pressure

gauge should be 100psi.

Slide the outlet taps outwards to allow air to escape from the outlets, and

slowly turn the pressure regiulator clockwise. Observe the pressure gauge.

When the pressure has dropped by approx. 20psi, the regulator will cut in

again. Close the sliding outlet valves and pressure in the air receiver will once

again increase

Finally, stop the engine and set the pressure regulator to zero pressure (turned

fully anticlockwise) and attach the air hose and air tool.

Open the sliding valves then set the pressure regulator to full pressure and

check for air leaks at the tool and connectors.

•

If leaks are apparent, stop the engine and set the regulator to zero pressure

(fully anticlockwise), press the trigger of the tool to ensure no air is present

in the airline, then rectify the problem before proceeding.

•

If no leaks are evident, set the outlet pressure to the desired value and

proceed to use the air tool in accordance with the manufacturers

instructions.

When starting subsequently, proceed as follows:

At the begining of the day, open the drain cock (see Fig.1) and allow any

condensate to drain completely, then close the cock.
