Assembly
The product requires assembly before first use:
- Place the compressor on a flat, stable surface.
- Attach the transport wheels to the wheel holders on the underside of the air nozzle using the provided screws.
- Attach the support foot to the bracket on the underside of the air nozzle using the provided screw.
- Install the air filter on the thread and tighten clockwise by hand.
- Check that the tank drain valve is tightly closed.
Operation
Always drain the pressure from the tank before performing maintenance or connecting tools. To start, press the lower part of the main switch. The compressor will automatically stop when the maximum pressure is reached and restart if the pressure drops. Always switch off the machine and drain the tank after use.
Maintenance
Proper maintenance is essential for safe operation:
- Before each use: Drain condensate from the tank, check for unusual sounds or vibrations, and ensure all nuts and bolts are tight.
- Every 10 hours: Clean the air filter.
- Every 40 hours: Check the air system for leaks using soapy water.
- Annually: Have the machine checked and adjusted by an authorized service center.
Troubleshooting
If the machine fails to start, check the power supply, fuse, or circuit breaker, and allow the motor to cool if overheated. If there is a pressure issue, check the safety valve, clean or replace the air filter, or have the non-return valve replaced by an authorized service center.
