6. Operating Instructions
This section outlines the general steps for operating your HPDMC air compressor. Always refer to the engine manufacturer's manual for specific starting procedures.
6.1 Starting the Compressor
- Pre-Start Checks:
- Check engine oil level.
- Check compressor pump oil level.
- Ensure fuel tank is adequately filled.
- Verify all connections are secure.
- Close the tank drain valve.
- Engine Start:
- Set the engine switch to "ON".
- Open the fuel valve.
- Apply choke if starting a cold engine.
- Manual Start: Pull the recoil starter handle firmly until the engine starts.
- Electric Start: Turn the ignition key (if equipped) or press the start button.
- Once the engine starts, gradually open the choke (if used).
- Pressure Build-up: Allow the compressor to run until the tank pressure reaches the desired level or the maximum operating pressure of 125 PSI. The pressure switch will automatically stop the engine when maximum pressure is reached.
6.2 Using Air Tools
- Connect your air hose to the air outlet valve.
- Attach the desired air tool to the hose.
- Adjust the air pressure regulator (if present) to the recommended pressure for your tool.
