Compressor Oil 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 line is located opposite
the service door. The proper oil level is in the middle 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
capacity is given in “Compressor Specifications”.
Maintenance
Air Intake Filter (P/N 308157)
The air intake filter is a heavy-duty dry type high efficiency filter designed to protect the compressor
from dust and foreign objects.
Frequency of maintenance of the filter depends on dust conditions at the operating site. The filter
element must be serviced when clogged. A clogged air filter element will reduce compressor performance
and cause premature wear of components.
Hydraulic Oil Cooler
The interior of the oil cooler should be cleaned when the pressure drop across it at full flow exceeds 25
PSI.
1. Remove cooler.
2. Circulate a suitable solvent to dissolve and remove varnish and sludge.
3. Flush generously with hydraulic oil.
4. Once the cooler is reinstalled, fill the hydraulic system with the proper fluid to their appropriate levels.
Do not attempt to drain condensate, remove the oil level fill cap, or
break any connection in the air or oil system without shutting off the
compressor and relieve the system of all stored air pressure.
No lubricant, however good and/or expensive, can replace proper main-
tenance and attention. Select and use it wisely.
Due to environmental factors, the useful life of all “extended life”
lubricants may be shorter than quoted by the lubricant supplier. Boss
encourages the user to closely monitor the lubricant condition and to
participate in an oil analysis program with the supplier.
