Read the
“Maintenance and Repair Safety” section prior to
performing any work on the system (beginning on Page 38).
Wear appropriate Personal Protective Equipment and follow
all industry standard safety practices.
Do not use compressed air or perform any other tasks
around the air filter and cover until both are replaced. Never
clean the filter element with compressed air as this may
allow contaminates to enter the compressor system. Always
replace the air filter element during this service.
Do not overfill the system. Overfilling the system with oil can
flood the sight glass window and make the system appear
empty.
Replace the blowdown muffler (Page 43).
Replace the pressure relief valve (Page 44).
Replace the air filter (Page 45).
Inspect the drive belt (Page 46).
Clean the area around the WHASP Tank and the oil filter to prevent
contamination.
Remove the oil drain plug and drain the oil into a container with a
capacity of at least 4 L (1 USG) (Figure 38).
Dependant upon the mounting location of the Gas Engine
Driven 30 CFM Air Compressor, the Remote Oil Drain Kit (P/N:
A500043) may help facilitate draining the compressor oil.
Inspect the Viton O-ring on the oil drain plug for damage, hardness or
defects and replace if necessary.
Install and tighten the oil drain plug.
Remove the oil filter (Figure 38).
