- Inspect the air hose and fittings for any leaks.
- Replace any damaged or leaking components.
- Tighten all fittings securely using a wrench.
3.7 Replacing a Faulty Pressure Switch
- Disconnect the electrical connections from the pressure switch.
- Remove the old pressure switch and replace it with a new one of the same type and pressure rating.
- Reconnect the electrical connections.
3.8 Replacing Worn or Damaged Piston Rings
- Remove the cylinder head from the air compressor.
- Remove the piston and inspect the piston rings for any wear or damage.
- Replace any worn or damaged piston rings with new ones.
- Reinstall the piston and cylinder head.
3.9 Replacing Loose or Worn Bearings
- Remove the motor from the air compressor.
- Remove the bearings from the motor housing.
- Install new bearings of the same size and type.
