8.3. Safety valve (10)
The safety valve has been set for the highest permitted pressure of the pressure vessel. It is prohib-
ited to adjust the safety valve or remove its seal. Actuate the safety valve from time to time to ensure
that it works when required. Pull the ring with sufficient force until you can hear the compressed air
being released. Then release the ring again.
8.4. Check the oil level at regular intervals
Stand the compressor on an even, flat surface. The oil level should be between MAX and MIN on the
viewing glass. Oil change: Recommended oil: SAE 15W/40 or similar product.
It should be refilled for the first time after 100 hours of operation. Thereafter the oil should be
drained and refilled after every 500 hours in service.
8.5. Changing the oil
Switch off the engine and pull the mains plug out of the socket. After releasing any air pressure you
can unscrew the oil drainage screw (15) from the compressor pump. To prevent the oil from running
out in an uncontrolled manner, hold a small metal chute under the opening and collect the oil in a
vessel. If the oil does not drain out completely, we recommend tilting the compressor slightly.
Dispose of the old oil at a drop-off point for old oil.
When the oil has been drained, replace the oil drainage screw (15). Fill new oil in the oil filling open-
ing (14) until the oil level has reached the nominal level. Then replace the oil stopper (14).
8.6. Cleaning the intake filter (1)
The intake filter prevents dust and dirt being drawn in. It is essential to clean this filter after at least
every 300 hours in service. A clogged intake filter will decrease the compressor’s performance dra-
matically. Remove the filter from the compressor and undo the thumb screw on the air filter. You can
then remove the filter from the two halves of the plastic housing, tap it to remove the dirt, blast it
down with low-pressure compressed air (approx. 3 bar) and re-insert it.

Attention!
Important!
Pull the mains plug out of the socket and ventilate the appliance and all connected
pneumatic tools. Switch off the compressor and make sure that it is secured in such a
way that it cannot be started up again by any unauthorized person.
Attention!
Important!
Store the compressor only in a dry location which is not accessible to unauthorized per-
sons. Always store upright, never tilted!
