• Keep the equipment free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it down with compressed air at low pressure.
• We recommend that you clean the equipment immediately after you use it.
• Clean the equipment 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 equipment. Ensure that no water can get into the interior of the equipment.
• 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.

Maintenance work on the pressure vessel (Fig. 1)
Important! To ensure a long service life of the pressure vessel (2), drain off the condensed water by opening the drain valve (3) each time after using.
Release the vessel pressure first (see 10.5.1). Open the drain screw by turning counter-clockwise (looking at the screw from the bottom of the compressor) so that all the condensed water can run out of the pressure vessel. Then close the drain screw again (turn it clockwise).

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, then please contact the customer service workshop.

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

Safety valve (Fig. 2)
The safety valve (9) has been set for the highest permitted pressure of the pressure vessel. It is not permitted to adjust the safety valve or remove the connection lock between the exhaust nut and its cap.
Actuate the safety valve every 30 operating hours but at least 3 times a year, to ensure that it works when required.
Turn the perforated drain nut anti-clockwise to open it.
Now, the valve audibly releases air. Then, tighten the exhaust nut clockwise again.

Cleaning the intake filter (Fig. 4)
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 dramatically. Open the screw (18) to remove the intake filter.
Then pull off the filter cover (17). Now you can remove the air filter (16). Carefully tap out the air filter, filter cover and filter housing. Then blow out these parts with compressed air (approx. 3 bar) and reinstall in reverse order.
