6.0 Operation
6.1 Precautions
Before operating the air compressor, always check first to ensure that it has been received, inspected
and installed in accordance with the instructions herein. Rectify any discrepancies before proceeding
further.
Check the compressor pump’s oil level by looking at the sight glass. The oil level should be at the top
of the red circle or at the “H” mark on the oil sight glass as shown in Figure 6-1. Add oil, if required,
through the oil fill cap and only when the unit is not operating. Do not overfill with oil. Refer to the
Maintenance and Repair section for recommended oil specifications. Note that 415 Volt oil free
compressors do not contain any oil in their compressor pumps; their bearings are sealed-for-life
rolling element type that do not need re-lubrication.

Check that the outlet valve, if fitted, is closed. Any connected air hose(s) or distribution pipe(s)
should not be open to the atmosphere; this is to prevent any injuries from “hose whip” or high-
pressure air discharge and also to avoid unattended compressed air discharge to the atmosphere. In
the event that an air line is cut or broken, the air supply must be immediately closed off at the
compressor either by shutting the discharge outlet valve or switching off the compressor. Do not
attempt to “catch” the loose end of a discharging air hose.
Check that the tank drain valve is closed.
If equipped with a filter-regulator, check that its drain valve is in the closed / semi-automatic position
with the arrow symbol on its handle pointing vertically upwards (▲) as shown in Figure 6-2.
Take care when discharging air from the tank, i.e. from the safety valve, the drain valve or the air
outlet, to ensure that it does not cause dirt, stones, metal swarf or other particles to be blown
around.
Any unusual noise or vibration likely indicates a problem with the compressor. Do not continue to
operate the unit until the source of the problem has been identified and corrected.
