When the oil has drained out, re-t the oil drain plug

(12).

Dispose of the old oil at a drop-off point for old oil.

To ll in the correct quantity of oil, make sure that the

compressor stands on an even surface. Fill new oil

through the oil ller opening (19) until it comes up to the

maximum level. This is marked with a red dot on the oil

level window (12) (Fig. 11). Do not exceed the maximum

lling quantity. Overlling the equipment may result in

damage. Reinsert the oil sealing plug (15) into the oil

ller opening (19).

10.6 Cleaning the intake lter (Fig. 3, 12, 13)

The intake lter prevents dust and dirt being drawn in.

It is essential to clean this lter after at least every 300

hours in service. A clogged intake lter will decrease

the compressor’s performance dramatically. Open the

screw (E) to remove the intake lter(2x).

Then pull off the lter cover (D). Now you can remove

the air lter (F). Carefully tap out the air lter, lter cover

and lter housing. Then blow out these parts with com-

pressed air (approx. 3 bar) and reinstall in reverse order.

10.7 Storage

m Important!

Pull out the mains plug and ventilate the equipment and

all connected pneumatic tools. Switch off the compres-

sor and make sure that it is secured in such a way that it

cannot be started up again by any unauthorized person.

12. Troubleshooting

Fault Possible cause Remedy

The compressor does

not start.

• No supply voltage.

• Insufcient supply voltage.

• Outside temperature is too low.

• Motor is overheated.

• Check the supply voltage, the power plug and the

socket-outlet.

• Make sure that the extension cable is not too

long. Use an extension cable with large enough

wires.

• Never operate with an outside temperature of

below +5° C.

• Allow the motor to cool down. If necessary, rem-

edy the cause of the overheating.

The compressor starts

but there is no pres-

sure.

• The safety valve (17) leaks.

• The seals are damaged.

• The drain plug for condensation water (10)

leaks.

• Have a service center replace the safety valve

(17).

• Check the seals and have any damaged seals

replaced by a service center.

• Tighten the screw by hand. Check the seal on

the screw and replace if necessary.

The compressor starts,

pressure is shown on

the pressure gauge, but

the tools do not start.

• The hose connections have a leak.

• A quick-lock coupling has a leak.

• Insufcient pressure set on the pressure

regulator (5).

• Check the compressed air hose and tools and

replace if necessary.

• Check the quick-lock coupling and replace if

necessary.

• Increase the set pressure with the pressure

regulator.

m Important!

Store the compressor only in a dry location which is not

accessible to unauthorized persons. Always store up-

right, never tilted! Oil may leak out!

10.7.1 Releasing excess pressure

Release the excess pressure by switching off the com-

pressor and using the compressed air which is still left

in the pressure vessel, e.g. with a compressed air tool

running in idle mode or with a blow-out pistol.
