Procedure
Oil system components
1. Run the compressor until warm. Stop the compressor. Close the air outlet valve and switch off the voltage.
Depressurise the compressor by opening manual drain valve(s) (Dm, Dm1). Wait a few minutes and
depressurise the air receiver/oil (AR) tank by unscrewing oil filler plug (FC) just one turn to permit any
pressure in the system to escape.
2. Drain the oil by opening valve (OD).
3. Collect the oil and deliver it to the local collection service. Refit and tighten the drain and vent plugs after
draining.
4. Remove the oil filter (OF). Clean the seat on the manifold. Oil the gasket of the new filter and screw it
into place. Tighten firmly by hand.
5. Remove filler plug (FC).
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).
6. Run the compressor loaded for a few minutes. Stop the compressor and wait a few minutes to allow the
oil to settle.
7. Depressurise the system by unscrewing filler plug (FC) just one turn to permit any pressure in the system
to escape. Remove the plug.
