to Be cARRIeD out AFteR eVeRY 100 houRs oF use:
a) check that the automatic cut-out at maximum pressure, and the automatic cut-in at 2bar below that, are operating correctly.
b) replace the lubricating oil. for oil specifications see below.
remove the oil drain plug (fig.2), draining the oil into a suitable container. drain when the compressor is hot so that oil drains
rapidly and completely. Incline compressor if needed to ensure complete drainage. replace the oil drain plug and pour oil through
the filler/dipstick aperture. check oil level with dipstick (fig.3) and
Do not
overfill.
Recommended oil:
the pump is filled with synthetic oil at the factory, if topping up or changing oil use a synthetic oil of sae
5W50 viscosity. alternatively a mineral oil can be substituted when carrying out an oil change, after ensuring that the synthetic oil has
been thoroughly drained first. use a mineral oil of sae 15W40 viscosity.
WARnIng! Do not mix different oils and do not use non-detergent/low quality oils, as the compressor may be damaged.
Dispose of all waste oil responsibly, in accordance with local authority requirements.

to Be cARRIeD out AFteR eVeRY 500 houRs oF use:
a) replace air filter.
b) check all tube fittings and electrical connections.
c) check all screws, nuts and bolts are tightly in place.
