MAINTENANCE
To avoid personal injury, always shut off and unplug the compressor and relieve all
air pressure from the system before performing any service on the air compressor.
Regular maintenance will ensure trouble free operation. Your electric powered air
compressor represents high quality engineering and construction; however, even
high quality machinery requires periodic maintenance. The items listed below
should be inspected on a regular basis.
CHECKING THE OIL
Check the level of oil in the pump with the sight glass. The pump oil level must be
between A and B (See Figure 7). Do not overfill or underfill.
CHANGING THE OIL
(Figure 6)
1. Remove the oil cap (1) on the pump.
2. Remove the sight glass (2) with a box-end wrench or socket. Drain the oil into
a suitable container and dispose of properly. The compressor may need to be
tipped slightly towards the drain hole to allow all of the oil to drain.
3. Reattach the sight glass (2). Be sure the gasket is between the sight glass and
the pump crankcase. Tighten the sight glass until the gasket is seated against
the pump crankcase and then tighten sight glass another 3/4 of a turn.
4. Refill the compressor with high quality compressor oil at slow intervals until the
oil reaches the center of the red circle in the sight glass (2). Replace oil cap (1)
on the pump.
