It is important to maintain your air compressor to keep it running in optimum condition, for safety and a long life. Besides doing precautionary steps, you will also save money and time that would usually be needed for repairs. Daily maintenance: Checking the level of the pump oil, checking for oil leaks, draining the tank water, checking for unusual sounds or noises, checking every single air leak, and inspection of belts. Weekly maintenance: Check all of the air filters, and if needed clean them, or replace them. Monthly maintenance: Do a checkup of the safety relief valve, check belts (if needed), tighten the bolts, and do a detailed check of possible leaks in the connections. Yearly maintenance: Once a year, you should service the engine or the pump.
