Boss Infinity Operator, Maintenance And Parts Manual page 19

If some of the maintenance intervals in the schedule outlined in this manual seem to be rather short,
it should be considered that one hour's operation of a compressor is equal to about 40 road miles
on an engine. Thus, eight hours operation is equal to 320 road miles, 250 hours is equal to 10,000
road miles, etc.
COMPRESSOR OIL SUMP FILL, LEVEL, AND DRAIN
Before adding or changing compressor oil make sure that the compressor is completely relieved of
pressure. Oil is added at the fill cap on the side of the compressor body. A drain valve/hose
assembly is provided at the bottom of the compressor body. The proper oil level is between the
top and the midpoint of the oil sightglass, when the unit is shut down and has had time to settle.
The truck must be level when checking the oil. DO NOT OVERFILL. The oil sump capacity is
given in "Compressor Specifications".
DO NOT ATTEMPT TO DRAIN CONDENSATE, REMOVE THE OIL LEVEL FILL
PLUG, OR BREAK ANY CONNECTION IN THE AIR OR OIL SYSTEM WITHOUT
SHUTTING OFF COMPRESSOR AND MANUALLY RELIEVING PRESSURE FROM
THE SUMP. FAILURE TO COMPLY WITH THIS WARNING MAY CAUSE DAMAGE
TO PROPERTY AND SERIOUS BODILY HARM.
AIR INTAKE FILTER
The air intake filter is a heavy-duty dry type high efficiency filter designed to protect the
compressor from dust and foreign objects. Optional two-stage available.
Optional filter is equipped with an evacuator cup for continuous dust ejection while operating and
when stopped.
Frequency of maintenance of the filter depends on dust conditions at the operating site. The filter
element must be serviced when clogged (maximum pressure drop for proper operation is 15" of
water). The filter is equipped with a pressure drop indicator, and the element should be changed
based on its reading first and then by the maintenance intervals outlined.
