  • Page 9: Specific Operation Warnings

    • To provide proper ventilation for cooling, the compressor must be kept a minimum of 12 inches (31 cm) from the nearest wall, in a well–ventilated area. • Fasten the compressor down securely if transporting is necessary. Pressure must be released from the tank before transporting.

  • Page 10: Main Parts Of Compressor

    Main Parts of Compressor Figure A Components Safety Valve: This valve is designed to prevent system failures by relieving pressure from the system when the compressed air reaches a predetermined level. The valve is preset by the manufacturer and must not be removed or modified in any way. Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.

  • Page 11: Hot Surfaces

    Components Motor Overload Protector: The motor has a thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart: Set the Auto/Off switch to OFF (O) and unplug unit. Allow the motor to cool.

  • Page 12: Assembly

    Assembly ⚠WARNING • This compressor was shipped with oil in the pump crankcase. Check oil before operating the air compressor. Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged in transit, contact the carrier and complete a damage claim. Do this immediately because there are time limitations to damage claims.

  • Page 13: Disconnecting Hoses

    Disconnecting Hoses 1. Ensure regulated pressure gauge reads 0 PSI. 2. Remove hose from air outlet. Installation Lubrication and Oil The air compressor pump was filled WITH oil at the manufacturer. Check air compressor pump oil level before operating unit. See the Compressor Pump Oil section under Pump Oil. Compatibility Air tools and accessories that are run off the compressor must be compatible with petroleum-based products.

  • Page 14: Wiring Instructions

    Wiring Instructions A qualified electrician needs to know the following before wiring: 1. The amperage rating of the electrical box should be adequate. Refer to the Technical Specifications (page 4) for this information. 2. The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on the side of motor, for this information.

  • Page 15: Extension Cords

    Extension Cords ⚠WARNING • USE A PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and cause overheating.

    NOTE: Some models are equipped with a dual voltage motor 115/230-volt. Most models are factory wired for 115-volt operation. If conversion from 115-volt to 230-volt is required, refer to the motor nameplate and have the conversion completed by a licensed electrician. Reset Switch Figure E How to Use Your Unit...

  • Page 18: Before Each Start-Up

    This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced. 1. Make sure the Auto/Off switch is in the OFF position. 2. Check the oil level in the pump. See the Checking Oil section in Pump Oil for instructions. 3.

  • Page 19: Operating Instructions

    ⚠CAUTION • Risk of unsafe operation. Compressed air from the unit may contain water condensation and oil mist. Do not spray un­filtered air at an item that could be damaged by moisture. Some air tools and accessories may require filtered air. Read the instructions for the air tools and accessories. Operating Instructions ⚠WARNING •...

  • Page 20: Maintenance

    Maintenance ⚠WARNING • Risk of unsafe operation. Unit cycles automatically when power is on. When performing maintenance, you may be exposed to voltage sources, compressed air, or moving parts. Personal injuries can occur. Before performing any maintenance or repair, disconnect power source from the compressor and bleed off all air pressure.

  • Page 21: Checking Safety Valve

    Maintenance Interval Maintenance Point * To check for air leaks, apply a solution of soapy water around joints. While compressor is pumping to pressure and after pressure cuts out, look for air bubbles to form. ** The pump oil must be changed after the first 20 hours of operation. Thereafter, when using synthetic blend, non-detergent air compressor oil, change oil every 100 hours of operation or once a year, whichever comes first.

  • Page 22: Pump Oil

    NOTICE: Risk of property damage. Drain the water from the air tank may contain oil and rust which can cause stains. 6. After the water is drained, close the drain valve (clockwise). The air compressor can now be stored. NOTE: If the drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, and reinstalled.

    Figure I Belt Replacement / Belt Tension / Motor Pulley & Flywheel Adjustment ⚠WARNING • This unit starts automatically. ALWAYS shut off and unplug the compressor and bleed all pressure from the system before servicing the compressor, and when the compressor is not in use. Do not use the unit with the shrouds or belt guard removed.

  • Page 24: Adjusting Belt Tension

    Adjusting Belt Tension 1. Slide the motor into its original position and line the motor up with the mark made earlier on the saddle. 2. Tighten the two outside motor mounting screws enough to hold the motor in place for checking pulley and flywheel alignment.

  • Page 25: Inspect Air Lines And Fittings For Leaks

    Inspect Air Lines and Fittings for Leaks 1. Set the Auto/Off lever to OFF, unplug the unit, and relieve all air pressure from the air tank. 2. Apply a soap solution to all air line fittings and connections/piping. 3. Correct any leaks found. IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in a premature breakdown or inadequate performance.
