Periodically inspect and replace the air filter. Blocked air filters significantly reduce compressor
performance. Never run the compressor without a filter
–
this will reduce the life of the compressor.
o
Periodically check fittings and airlines for leaks.
o
Periodically inspect mount bolts to ensure that they remain tight.
o
Periodically check the safety relief valve
–
ensure air is released when the manual override is pulled.

The compressor does not use oil lubrication
–
there is no requirement to check / fill oil.
