Assembly

Before using the compressor, ensure all parts are assembled correctly:

• Install the wheels and rubber feet as shown in the assembly diagrams.
• Ensure the air filter is properly installed.
• Check that all bolts and nuts are tightened securely.

Starting-up

Follow these steps to prepare the compressor for operation:

• Check the oil level (use 5W-40 oil).
• Ensure the compressor is placed on a stable, vertical surface.
• Check that the drain valve is closed.
• Connect the air hose to the quick-acting coupling.
• Ensure the power supply matches the voltage on the type label.

Operation

To operate the compressor:

• Use the ON/OFF switch to start and stop the machine. Never use the plug to switch the compressor on or off.
• The compressor will automatically stop when the maximum pressure is reached and restart when the pressure drops.
• Always maintain a safety distance of at least 4 meters between the compressor and the work area.
• At the end of the workday, switch off the compressor, drain the air from the tank, and unplug it.

Maintenance

Regular maintenance is crucial for safety and performance:

• Drain Condensate: Every 2-4 hours of use, drain the condensate from the tank. Ensure the pressure is low (max 1 bar) before opening the drain valve.
• Air Filter: Regularly clean or replace the air filter if it becomes dirty.
• Check Valve: Periodically inspect the check valve for leaks or damage.
• General: Keep the compressor clean and free of dust. Use only original spare parts.

Troubleshooting

If you encounter issues, refer to the following:

• Compressor not starting: Check power supply, pressure switch, or if the tank pressure is too high.
• Compressor runs continuously: Check for leaks, dirty air filter, or excessive air consumption by tools.
• Air leaks from discharge valve: Clean or replace the discharge valve.
• Compressor overheats: Ensure proper ventilation (min 40cm from wall) and clean cooling fins.

Safety

Always wear safety goggles and ear protection. Never direct the air jet at people, animals, or yourself. Do not operate the compressor in the rain or in the presence of explosive gases.
