All parts under the coolers covered?

Dirt removed from the coolers with a fibre brush?

Note: Never use a wire brush or metal objects.

Cleaned with an air jet in the reverse direction to normal flow?

Enter the air pressure used for cleaning

Replace the filter element of the electric cabinet (if applicable)

Check pressure and temperature readings

If provided, remove, dismantle and clean float valve of condensate trap

Clean the condenser of the dryer (Full-Feature compressors)

For GA with integrated dryer clean condenser of dryer every 2000 Hours

Compressor stopped, air outlet valve closed and voltage switched off?

Front panel and right panel removed?

Belt tension adjusted by turning nuts?

Enter the force F needed to create a deflection of 5 mm (0.2 in)

WARNING! The operator must apply all relevant Safety precautions

Run the compressor until warm. Stop the compressor, close the air outlet valve and switch off the voltage

Wait a few minutes and depressurise by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape

Wait 5 minutes and remove the oil separator (OS). Clean the seat on the manifold. Oil the gasket of the new separator and screw it into place. Tighten firmly by hand

Fill the oil tank (OT) with oil until the level reaches the middle of sight-glass (Gl)

Take care that no dirt drops into the system. Refit and tighten filler plug (FC)

Sign off on the oil separator replacement

Check that condensate is discharged during loaded operation

Drain condensate (compressed air receiver)

Check the pressure dew-point temperature (compressors with integrated dryer)
