Model G0471 3 HP Air Compressor
-10-
Figure 6. Proper oil level.
6. Remove the oil breather (inset in Figure
6) on top of the crankcase and add
compressor oil, or ISO 100/SAE 30W
non-detergent oil, to the crankcase.
The oil level should be in the center of
the sight glass as shown in Figure 6.
NOTICE
Never run this compressor without
a full oil reservoir. The oil provides
lubrication to the cylinder rings,
which deliver the compressed air.
Severe damage to the internal mov-
ing parts can occur if there is not
adequate oil flow. Check the oil level
frequently, and change the oil every
3 months.
Oil Breather

5. Slide the handle into the sockets on the
tank and secure with M8-1.25 x 45 hex
bolts, flat washers, lock washers, and
hex nuts as shown in Figure 5.
NOTICE
The oil breather releases excess
pressure from the crankcase.
Clogged holes in the oil breather
can lead to damaged oil seals, gas-
kets, and may cause the compres-
sor to seize.
