Maintenance
Initially the filter should be replaced after the first 50 hours of operation, then every 500 hours or 6
months. A dirty filter can restrict oil flow, causing high oil temperature, which will result in a system
shutdown.
I.
Compressor Oil Filter Replacement
A. Verify the compressor oil system is drained.
B. Using a strap wrench, remove the oil filter and o-ring.
C. Clean o-ring seating surface on the oil filter head.
D. Apply a light film of oil to the new o-ring.
E. Hand tighten new filter until o-ring is seated in o-ring groove.
F. Continue tightening filter by hand an additional 1/2 to 3/4 turn.
G. Continue with Changing the Compressor Oil steps.
8.11 Compressor Oil Filter
Substitute filters may have inadequate working pressure
limits, resulting in filter leakage or rupture. Replacement
filters must be the same quality and type as the original Boss
Industries, Inc. oil filter.
Mechanical over-tightening may distort the threads or damage
the filter element seal.
H. Replace fill cap and tighten immediately.
I.
Run system briefly to see if more oil needs to be added and to ensure there are no leaks.
Do not replace fill cap with a pipe cap; serious injury or dam-
age could result. Replacement filters must be the same
quality and type as the original Boss Industries, Inc. fill cap.
8.10
Compressor Oil Cooler
Any sign of leakage from the compressor oil cooler justifies a pressure test to ensure its integrity.
Cooler leaks should only be repaired by qualified service technicians. Dirt that clogs the cooling fins of
the cooler should be removed. The use of an air stream or high-pressure steam cleaner should be done
with caution so as to not damage the delicate fins. Bent cooling fins will reduce the cooling capability of
the compressor oil cooler.
8.9 Compressor Oil (continued)
III. Changing Compressor Oil (continued)
G. Dexron III® ATF can now be added until the oil level reaches halfway in the sightglass. Do not
over fill the separator tank. This will cause oil carryover in the discharge line and at blowdown.
