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