Changing the V-belt (Fig. H to K)
To change the V-belt on the compressor, please be sure to disconnect the device from the mains.

Once the compressor has been successfully disconnected from the mains, remove the protective grate by turning the plastic clips (33) 90° using pliers. Then remove the screw (31) including washers (32), which connects the protective grate (2) with the motor (4) using a 4 mm Allen key. Now undo the four screws (33) on the motor (4) with two size 14 spanners, so that you can subsequently slide the motor. It is now possible to change the V-belt (3). After successfully changing the V-belt, perform the same steps in reverse order to bring the device back into operational condition. Make sure the motor is bolted at a right angle to the running direction, in order to guarantee fault- free running of the V-belt.

Maintenance of the pressure vessel Attention!
To ensure a long service life for the pressure vessel (12), drain off the condensate after each use by opening the drain screw (21). Release the vessel pressure beforehand (see 10.5). The drain screw is opened by turning it counterclockwise (when looking at the screw on the bottom of the compressor) so that the condensate can be completely drained out of the pressure vessel. Then close the drain screw again (turn clockwise). Check the pressure vessel for rust and damage each time before use. The compressor shall not be operated if the pressure vessel is damaged or rusty. If you discover damage, please contact the customer service workshop.
m Attention! The condensate from the pressure vessel contains oil residue. Dispose of the condensate in an environmentally friendly manner at a suitable collection point.

Safety valve (Fig. B)
The safety valve (20) is set to the maximum permissible pressure of the pressure vessel. It is not permitted to adjust the safety valve or to remove the connection lock (20.2) between the drain nut (20.1) and its cap (20.3).
In order for the safety valve to function properly when needed, it must be actuated every 30 operating hours and at least 3 times a year. Turn the perforated drain nut (20.1) anti-clockwise to open it, then pull the valve stem outwards by hand via the perforated drain nut (20.1) to open the safety valve outlet.

Now, the valve audibly releases air. Then turn the drain nut clockwise again to tighten.

Check the oil level at regular intervals (Fig. F)
Place the compressor on a level and straight surface. The oil level must be at the center of the oil sight glass (16) (red dot).

Oil change (Fig. L)
The first oil filling must be changed after 10 operating hours; afterwards, perform an oil change every 50 operating hours.
Switch the motor off and unplug the mains plug from the power outlet. Remove the oil drain screw (15). Additionally open the oil plug (18).
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. Once the oil has fully drained out, replace the oil drain screw (15). Dispose of the old oil at a drop-off point for old oil.
To fill in the correct quantity of oil, make sure that the compressor stands on an even surface. Remove the oil plug (18) and add new oil through the oil filler hole until the oil level in the oil sight glass (16) has reached the correct quantity (red dot).
Do not exceed the maximum filling quantity. Overfilling the equipment may result in damage. Reinsert the oil plug (18) in the oil filler hole.

Cleaning the air filter
The air filter prevents dust and dirt being sucked in. It is necessary to clean this filter at least every 300 operating hours. A blocked air filter significantly reduces the compressor power. Remove the air filter by opening the wing nut (27) on the air filter housing (1). Remove the wing nut (27) and washer (28). Then draw out the air filter housing (1). Draw the air filter housing (1) apart. You can now remove the air filter. Carefully knock out the air filter and the parts of the filter housing.

These components must then be blown out with compressed air (approx. 3 bar) and reassembled in reverse order.
