Frequently Asked Questions - RT-AC 400/100/10 D EINHELL

How to start the compressor?

Ensure the On/Off switch (red button) is in the off position. Plug the CEE 16A plug into a suitable 400 V socket. Check the motor's rotation direction (arrow). If the motor rotates in the wrong direction, use the phase inverter. Then press the green button to start. The compressor will stop automatically at 10 bar.

How to adjust the output pressure?

Use the pressure regulator (7) to adjust the pressure on the pressure gauge (6). The set pressure is available at the quick coupling (5). The maximum pressure is 10 bar, but you can reduce it for certain tools.

How often should condensed water be drained?

Condensed water must be drained daily by opening the drain screw (11) at the bottom of the tank. Caution: Condensed water contains oil residues, dispose of it at a suitable collection point.

How to check and change the oil?

Place the compressor on a level surface. The oil level must be between MAX and MIN on the sight glass. To drain, disconnect the power, unscrew the drain plug (15) and collect the used oil. Fill with SAE 15W/40 oil or equivalent to the correct level. Replace the cap (14). First change after 100 hours, then every 500 hours.

What to do if the compressor does not start?

Check the mains voltage, fuse, and socket. Below +5°C, the motor may have difficulty starting. If the motor is too hot, let it cool down. If the problem persists, contact after-sales service.

How to clean the suction filter?

Unplug the unit. Loosen the two hexagon socket bolts (B) to remove the filter. Tap it or blow it out with compressed air (max 3 bar). Clean every 300 hours of service to avoid power loss.

Why does the compressor stop during operation?

Automatic stop is normal when pressure reaches 10 bar (cut-off pressure). If the compressor stops earlier, it may be due to overheating (overload switch) or a fault. Let it cool down and check the causes of overload.

Can I use the compressor for painting?

Yes, provided that paints and solvents with a flash point above 55°C are used. Wear a mask and eye protection. Work in a well-ventilated area (>30 m³) and do not smoke. Follow safety instructions.

7.2 Condensation water (Fig. 4)

The condensation water must be drained off each day by opening the drain valve (11) (on the floor of the pressure vessel).

⚠️ 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.

7.3 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.

7.4 Check the oil level at regular intervals

Place the compressor on a level and straight surface. The oil level must be between the two marks MAX and MIN on the oil oil level window (Fig. 14/Item 16). 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.

7.5 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).

7.6 Retensioning the V-belt (Figs. 15-17)

●Pull out the power plug and remove the safety guard for the V-belt.
●Slacken the four motor fixing screws (A).
