⚠️ Important!

Wait until the compressor has completely cooled down. Risk of burns!

⚠️ Important!

Always depressurize the tank before carrying out any cleaning and maintenance work.

8.1 Cleaning

• Keep the safety devices free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it with compressed air at low pressure. We recommend that you clean the appliance immediately after you use it. Clean the appliance regularly with a damp cloth and some soft soap. Do not use cleaning agents or solvents; these may be aggressive to the plastic parts in the appliance. Ensure that no water can get into the interior of the appliance.
• You must disconnect the hose and any spraying tools from the compressor before cleaning. Do not clean the compressor with water, solvents or the like.

8.2 Condensation water

Important. To ensure a long service life of the pressure vessel (2), drain off the condensed water by opening the drain valve (11) each time after using. Check the pressure vessel for signs of rust and damage each time before using. Do not use the compressor with a damaged or rusty pressure vessel. If you discover any damage, please contact the customer service workshop.

Important! The condensation water from the pressure vessel will contain residual oil. Dispose of the condensation water in an environmentally compatible manner at the appropriate collection point.

8.3 Safety valve (10)

The safety valve has been set for the highest permitted pressure of the pressure vessel. It is prohibited 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 (Fig.10)

Place the compressor on a level and straight surface. The oil level must be between the two marks MAX and MIN on the oil level window. Changing the oil: Recommended hydraulic oil: SAE 15W/40 or an alternative of the same quality. 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 drained out, re-fit the oil drainage screw (15). Fill new oil through the oil filler opening (14) until it comes up to the required level. Then replace the oil sealing plug (14).

8.6 Cleaning the intake air filter (Fig. 7, 8)

The intake filter prevents dust and dirt from being drawn in. Clean this filter at least every 300 hours. In environments with increased dust and dirt pollution, the cleaning process must be carried out more frequently.

A clogged intake filter will decrease the compressor's performance dramatically. Only use the compressor with an intact intake air filter.

Remove the filter from the compressor by unscrewing the two screws (L).

Remove the filter foam (N) from the two housing parts of the filter (M, O). Clean the filter material by tapping and blowing it at low pressure (approx. 3 bar).

Assemble and fit the intake air filter in reverse.

8.7 Storage

⚠️ 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.
