OPERATING INSTRUCTIONS

Please read and follow the operating instructions carefully to assure that you will enjoy the convenience and best use out of your air compressor.

1. Always operate the compressor AT OR BELOW THE MAXIMUM PRESSURE RATING of the compressor. Refer to Specifications section of this manual.

2. Always OBSERVE THE MAXIMUM DUTY CYCLE of the air compressor. Refer to Specifications section of this manual for details. Operations exceeding maximum pressure ratings and or duty cycle will result in damage to air compressor.

3. Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR. This feature is designed to protect the air compressor from over-heating and causing permanent damage to your air compressor. The thermal overload protector will automatically cut off power to air compressor should internal operating temperature of the air compressor rise above safe levels during excessive use.

4. Should your compressor shut off suddenly after extended use, do not attempt to restart air compressor. Turn ON/OFF switch of air compressor to the OFF position. The automatic thermal overload protector will automatically reset when internal temperature of the air compressor drops below safe level. After allowing air compressor to cool off for about 30 minutes, you can safely resume use of the air compressor by turning on the air compressor.

5. For your convenience, and to protect the air compressor from over-pressure operation that can cause permanent damage to the unit – this compressor is equipped with built-in pressure switch with a factory set cut-on pressure of 130 PSI (± 5%) and a factory set cut-off pressure of 155 PSI (± 5%). During inflation of tire pressures between 130 PSI to 155 PSI, if you stop inflation, the compressor may not restart. This is completely normal, since inline pressure is greater than cut-on pressure of the pressure switch and less than cut-off pressure of the pressure switch.
   To restart compressor, deflate tire pressure to below 130 PSI, reconnect tire chuck to tire valve stem and resume tire inflation.

6. Please note that you may experience a slight delay of the compressor’s motor starting when the ON/OFF switch is turned on while compressor is pressurized (when there is pressure in the line that the compressor is connected to). This is a normal delayed reaction, not a Compressor ON/OFF switch malfunction.

7. It is strongly recommended that you keep the vehicle’s engine running while using the air compressor to prevent discharge of your vehicle’s battery.

8. ONLY OPERATE THE AIR COMPRESSOR IN WELL VENTILATED AREAS.
   Compressor performance is enhanced when operating compressor with vehicle engine running.

IMPORTANT: Engine must be running while using this compressor.
Before attaching air compressor power clamps to your vehicle’s battery terminals, check to make sure that the ON\/OFF switch of your compressor is in the OFF position. Attach the Positive (+) battery clamp (Red) to the Positive terminal of the battery and the Negative (-) battery clamp (Black) to the Negative terminal of the battery. Always keep your vehicle’s engine running while operating compressor to avoid draining your vehicle’s battery.

CAUTION: Your Portable Air Compressor is Moisture and Dust Resistant, but NOT WATER OR DUST PROOF. Never place compressor in soft sand while running the compressor. Vibration from the compressor will cause the compressor to settle into soft sand, resulting in compressor drawing in foreign particles. Never expose compressor to water while running the compressor.

This air compressor comes with 1/4” quick connect stud. A primary coil hose, an extension coil hose and a tire inflation gun are also included with your compressor. Both ends of the primary hose are equipped with 1/4” quick connect couplers. The rubber overmold end should be connected to the compressor itself. One end of the extension coil hose is equipped with a 1/4” quick connect coupler, and the other end with a quick connect stud. The extension hose is used to elongate overall reach. The tire inflation gun comes with a 1/4” quick connect stud, pressure gauge, rubber hose, bleeder valve and tire chuck. Attach one end of the extension coil hose to the stud on your compressor and the other end to the stud on the tire gun kit. The tire gun kit can be used for both airing up and airing down. Please familiarize yourself with the following functions of this versatile air tool:

TIRE INFLATION

1. Attach one end of the extension coil hose to the compressor and the other end to the tire gun kit, 45- degree angled chuck or 90-degree twist-on chuck – depending on need.
2. Turn compressor switch on and hold down the trigger on the tire gun kit to begin inflation.
3. When desired pressure is reached, release the trigger. If finished with use, turn power switch on compressor off position.

NOTE: To release excess pressure, turn off compressor and disconnect hose from compressor. With the tire inflation gun still connected to the other end of the coil hose, pull trigger on the tire inflation gun to release excess pressure.
CAUTION: To avoid over inflation, never exceed recommended pressure on articles to be inflated. Bursting can cause serious injury.
NOTE: Your air compressor is equipped with a pressure switch (cut on at 130 PSI, cut off at 155 PSI). This feature is designed to protect the air compressor from over-pressure causing permanent damage to your air compressor. The pressure switch automatically turns off the motor when the internal pressure of the air compressor reaches the factory set “cut-off” pressure of 155 PSI and restarts when the internal pressure drops below 130 PSI.

TIRE DEFLATION

1. With the inflation option of your choice still connected to the tire inflation gun, press the bleeder valve button on the tire gun kit to decrease tire pressure.
2. When desired pressure is reached, release the bleeder valve button to stop tire deflation.

IMPORTANT: Make sure compressor sits upright while operating compressor. Do not operate compressor in any other position. Avoid tugging at compressor to move it. Instead, move compressor to the same side of vehicle as tires that are being aired up.
Always make sure the Portable Compressor’s power cord is uncoiled and fully extended when using your air compressor to avoid overheating the power cord.

INLINE PRESSURE GAUGE

1. The pressure gauge on the inflation gun provides convenient tire pressure monitoring when airing up or down (not airflow of the compressor). This eliminates switching back and forth between a tire chuck and a tire pressure gauge.
2. Please note that during inflation and deflation, due to air velocity, pressure gauge cannot provide accurate pressure readings. Release lever on the tire inflation gun during inflation to check tire air pressure.

NOTE: To release excess pressure, turn off compressor and disconnect hose from compressor. With the tire inflation gun still connected to the other end of the coil hose, pull trigger on the tire inflation gun to release excess pressure.

SAFETY PRECAUTIONS

1. Always inflate tires to manufacturer’s recommended tire pressures. Exercise extreme caution when driving with aired-down tires. Reinflate tires before high-speed roadway travel.
2. Never exceed 20 M.P.H. when driving with partially inflated tires.
3. Never make sharp turns while driving with reduced tire pressure.
4. Re-inflate tires before high speed traveling onto roadways.
5. Use heat-resistant, minimum 200 PSI-rated working pressure extension hose.
   Do not use aftermarket hoses with less than 200 PSI working pressure. Some aftermarket hoses may not be suitable for use with this air compressor due to heat and pressure typically generated by this type of air compressors.
   CAUTION: Never touch the air compressor or fittings connected to the air compressor other than the ON/OFF switch with bare hands during or immediately after use. The extension hose and fittings connected extension hose will become very HOT during and after use. If necessary, wear heat resistant gloves to remove hose from the compressor quick connect stud.

MAINTENANCE & REPAIRS

Your air compressor is equipped with permanently lubricated, maintenance-free motor.
Never try to lubricate the compressor. Regularly clean dust and dirt from compressor cooling fins and motor housing. All repairs should be performed by Manufacturer or Manufacturer authorized service agencies only.
