2. Safety Information

Always observe the following safety precautions to reduce the risk of electric shock, fire, or serious injury.

• Read All Instructions: Familiarize yourself with the compressor's controls and proper operation.
• Electrical Safety: Ensure the power source matches the compressor's voltage (115 Volts AC). Do not operate in wet conditions. Always use a grounded outlet.
• Personal Protective Equipment: Wear safety glasses or goggles when operating the compressor or using air tools. Hearing protection is recommended, especially during prolonged use.
• Operating Environment: Operate the compressor in a well-ventilated area. Keep children and bystanders away. Do not operate near flammable liquids or gases.
• Pressure Safety: Never exceed the maximum operating pressure of any air tool or accessory. Do not attempt to modify the pressure relief valve.
• Maintenance: Disconnect power before performing any maintenance or repairs.
• Hot Surfaces: The compressor pump and motor can become hot during operation. Avoid contact with hot surfaces.

4. Setup

1. Unpacking: Carefully remove the compressor from its packaging. Inspect for any shipping damage. Report any damage to your dealer immediately.
2. Placement: Place the compressor on a firm, level surface in a clean, dry, and well-ventilated area. Ensure adequate clearance around the unit for air circulation.
3. Electrical Connection:
   • Verify that the power supply voltage matches the compressor's requirements (115 Volts AC).
   • Plug the power cord into a grounded electrical outlet. Avoid using extension cords if possible. If an extension cord is necessary, use a heavy-duty, grounded cord of appropriate gauge for the distance.
4. Initial Drain: Before first use, ensure the quarter-turn drain valve at the bottom of the tank is closed.

5. Operating Instructions

1. Power On: Locate the ON/OFF switch (typically a rocker switch or pressure switch) and turn the compressor ON. The compressor will begin to build pressure.
2. Pressure Build-Up: Allow the compressor to run until it reaches its maximum pressure and the motor automatically shuts off. This indicates the tank is fully charged.
3. Connecting Air Tools:
   • Attach your air hose to the quick-connect coupler on the compressor.
   • Connect your air tool to the other end of the hose.
4. Adjusting Output Pressure: Use the pressure regulator knob to set the desired output pressure for your air tool. Monitor the regulated pressure gauge.
5. Operation: Begin using your air tool. The compressor will cycle on and off automatically to maintain tank pressure as air is consumed.
6. Power Off: When finished, turn the compressor OFF using the ON/OFF switch.
7. Depressurize: Disconnect the air hose and tool. Allow any remaining air in the tank to escape through the drain valve or by briefly opening the regulator.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Rolair JC20 compressor. Always disconnect the power before performing maintenance.

• Daily: Drain Moisture from Tank:
  • With the compressor off and tank depressurized, open the quarter-turn drain valve located at the bottom of the tank.
  • Allow all accumulated moisture to drain completely.
  • Close the drain valve securely.
• Weekly/Monthly: Inspect Air Filter:
  • Check the air intake filter for dirt and debris.
  • Clean or replace the filter as necessary. A clogged filter can reduce compressor performance and lifespan.
• Periodically: Inspect for Leaks:
  • With the compressor pressurized, apply a soapy water solution to all fittings and connections.
  • Bubbles indicate a leak. Tighten connections or replace seals as needed.
• Storage: Store the compressor in a clean, dry location. Ensure the tank is drained of moisture before storage.
