OIL FILTER
The compressor oil filter is a throwaway type cartridge. It is designed with a built-in bypass so that
if there is a large restriction, due to cold oil or clogged element, the compressor will still be
lubricated.
To replace filter proceed as follows:
1. Make sure system pressure is relieved.
2. Unscrew with 14mm allen wrench.
3. Remove oil filter from housing.
4. Replace the oil filter screen element.
5. Reinsert oil filter screen into housing and tighten with 14mm allen wrench.
6. Add oil (total system takes one gallon), re-tighten filler cap.
7. Check for leaks in operation.
DO NOT SUBSTITUTE ELEMENT. USE ONLY A GENUINE BOSS INDUSTRIES
REPLACEMENT ELEMENT. USE OF ANY OTHER ELEMENT MAY BE
HAZARDOUS AND COULD IMPAIR THE PERFORMANCE AND RELIABILITY
OF THE COMPRESSOR, POSSIBLY VOIDING THE WARRANTY AND/OR
RESULTING IN DAMAGE TO PROPERTY AND SERIOUS BODILY HARM.
HYDRAULIC OIL COOLER AND COMPRESSOR OIL COOLER COMBINATION
The interior of the oil cooler should be cleaned when the pressure drop across it at full flow
exceeds 25 PSI. The following procedure has been recommended by the vendor who supplies the
cooler:
1. Remove cooler.
2. Circulate a suitable solvent to dissolve and remove varnish and sludge.
3. Flush generously with compressor lubricant (compressor oil cooler section only, use
hydraulic oil to flush the hydraulic cooler portion on the combo cooler).
4. Once the coolers are reinstalled, fill the compressor and hydraulic systems with the
proper fluids to their appropriate levels.
