Air Compressor Maintenance Checklist

Most compressor breakdowns we see in the workshop could have been avoided with a few simple checks. Here is what to do and when.

Daily

• Drain the water from the tank. Moisture builds up every time the compressor runs and rusts the tank from the inside.
• Listen for new noises or air leaks.

Weekly

• Check the oil level on lubricated compressors and top up with compressor oil, not engine oil.
• Check the intake filter and clean it if dusty.
• Check hoses and couplings for damage or leaks.

Every 3 to 6 months

• Change the oil (follow the hours in your manual).
• Replace the intake filter.
• On belt drive units, check belt tension and wear.
• Pull the safety valve ring briefly to check it is not stuck.

Yearly

• Have the compressor serviced.
• Have the air receiver examined. Pressure vessels used at work need periodic examination by a competent person under health and safety law.

Warning signs

• Compressor runs constantly or takes longer to fill
• Oil in the air line
• Overheating or tripping
• Water spitting from tools
