General Service Information
Safety and Service Precautions
Observe these precautions when performing any service:
Never attempt to clean the air filter element with compressed air. Replace the air filter element.
To prevent damage to the oil filter, always use a proper filter wrench. Never over-tighten the filter, as this may damage
the seal or the filter. Apply a thin coating of compressor oil to the filter sealing gasket.
Never use any lubricant other than the supplied compressor oil, as other lubricants will damage the compressor and may
void warranty.
Do not overfill the system, as this can flood the oil level sight tube and make the system appear empty.
If the system has been operating, shut it off and wait at least 30 seconds for the air pressure to vent before performing
service.
You must make sure that there is no pressure left in the system. If there is a pressure gauge, make sure that
it is at zero before commencing service. If you are not sure, attach a tool or air nozzle to the air outlet and
make sure that there is no pressure.
If the system is cold, bring the engine to operating temperature and then operate the compressor system for a few
minutes to bring the compressor oil to operating temperature. This will also help to suspend contaminants in the oil so
that they can be removed from the system along with the old oil.
Observe all safety procedures relating to moving belts, hot oil and compressed air. Use all safety equipment to protect
yourself.
Check the old oil for any evidence of metal filings or contamination; if found, flush the tank, hoses and cooler. Metal
filings will damage the compressor.
Flushing Procedure
Component failure (such as a gearbox, compressor, hose or cooler core) can leave metal filings and other foreign materials
in the system. To flush the system, follow this procedure:
1. Before replacing any failed component, check all other system components for evidence of contamination and clean
thoroughly. Use compressed air to blow out lines and other components. Remove the oil filter and dump out oil from the
filter. If there is no metal in the oil filter, continue with the regular flush procedure, (continue to step 2).
If there is metal in the oil filter, look for metal in the return line to the compressor. If metal is found, the cooler must be
flushed before the new compressor is installed. As well, the lines from the tank to the cooler and cooler to compressor
need to be thoroughly checked / flushed or replaced before installing the new compressor.
2. Once the system has been cleaned as thoroughly as possible, replace the failed component and reconnect all lines and
fittings
3.
Install a new oil filter and fill the system with VMAC compressor oil to the correct level.
4.
Start the engine and engage the air system. Allow the system to pressurize and allow it to operate in no-load mode for
about 15 minutes without discharging any air.
5.
Shut-down, allow the system to cool and change the oil and the oil filter. Refill with compressor oil to the correct level.
6.
After 50 hours, replace the oil filter and top up the oil level.
