Air compressors are complex machines with many moving parts. Regular maintenance is essential for ensuring all compressor parts and components function at their highest level, and for preventing wear that can ultimately lead to premature failure. One crucial component in maintaining your air compressor is changing the oil, the following instructions and video will explain how.

Changing the oil in a ELGi air compressor

Turn the unit off
Turn the power off at the fuse box and lock it out so no one can turn the power back on
Cover the unit in case of spillage
Open the drain valve with an open end wrench
Open the oil intake valve
Insert a funnel so the oil can drain into a bucket
Drain the oil
Pour 1.62 quarts of oil into the compressor
Fill oil to mid level on the oil sight gauge
Retighten the valves

Cleaning the air filter
ELGi uses polyester air filters so they can easily be removed and cleaned with just soap and water. This not only extends the life of the air filter, but also filters the air at a rate of 10-20x cleaner than a standard foam or paper filter. Once the polyester air filter has been washed, dry it, put it back in place and tighten things up.

Maintenance stickers
When your maintenance is complete, record the updated data and establish the next date of maintenance on the machine stickers.
