- Never point any air nozzle or air sprayer toward another person or any part of the body.
- This air compressor is equipped with an Automatic Reset Thermal Protector, and can automatically restart after the thermal overload protector resets. Always cut off power source when thermal protector becomes activated.
- Wear safety glasses or goggles when operating this product.
- Use only in well-ventilated areas.
- After usage, always release excess pressure from the coil hose by turning the On/Off switch to the Off position, disconnect the hose from the compressor, and with the tire inflation gun still connected to the other end of the coil hose, pull the trigger on the tire inflation gun to release excess pressure.
Operating Instructions
Please read and follow the operating instructions carefully to ensure you will enjoy the convenience and best use of your air compressor.
- Always operate the compressor AT OR BELOW THE MAXIMUM PRESSURE RATING of the compressor. Refer to the Specifications section of this manual.
- Always OBSERVE THE MAXIMUM DUTY CYCLE of the air compressor. Operations exceeding maximum pressure ratings and/or duty cycle will result in damage to the air compressor.
- Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR. This feature is designed to protect the air compressor from overheating and causing permanent damage. The thermal overload protector will automatically cut off power to the air compressor should internal operating temperature rise above safe levels during excessive use.
- Should your compressor shut off suddenly after extended use, do not attempt to restart it. Turn the ON/OFF switch to the OFF position. The automatic thermal overload protector will reset when the internal temperature drops below a safe level. After allowing the compressor to cool off for about 30 minutes, you can safely resume use by turning the compressor back on.
- For convenience and to protect the compressor from over-pressure operation, it is equipped with a 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 and 155 PSI, if you stop inflation, the compressor may not restart. This is normal as the inline pressure is between the cut-on and cut-off pressures. To restart, deflate the tire pressure to below 130 PSI, reconnect the tire chuck to the tire valve stem, and resume inflation.
- You may experience a slight delay of the compressor's motor starting when the ON/OFF switch is turned on while the compressor is pressurized. This is a normal delayed reaction, not a switch malfunction.
- It is strongly recommended to keep the vehicle's engine running while using the air compressor to prevent discharge of your vehicle's battery.
- ONLY OPERATE THE AIR COMPRESSOR IN WELL VENTILATED AREAS. Compressor performance is enhanced when operating with the vehicle engine running.
IMPORTANT: Engine must be running while using this compressor.
Before attaching air compressor power clamps to your vehicle's battery terminals, ensure the ON/OFF switch 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 the 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 the compressor in soft sand while running. Vibration will cause it to settle into soft sand, drawing in foreign particles. Never expose the compressor to water while running.
Operating Instructions (Continued)
This air compressor comes with a 1/4” quick connect stud. An extension coil hose and a tire inflation gun are also included. Each end of the extension coil hose is equipped with a 1/4" quick connect coupler. The tire inflation gun has 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 compressor stud and the other end to the tire gun kit stud. The tire gun kit can be used for both airing up and airing down. Familiarize yourself with the functions of this air tool:
Tire Inflation:
- Attach one end of the extension coil hose to the compressor and the other end to the tire gun kit, using the 45-degree angled chuck or 90-degree twist-on chuck as needed.
- Turn the compressor switch on and hold down the trigger on the tire gun kit to begin inflation.
- When desired pressure is reached, release the trigger. Turn the compressor power switch to the off position when finished.
NOTE: To release excess pressure, turn off the compressor and disconnect the hose. With the tire inflation gun still connected to the coil hose, pull the trigger on the gun to release excess pressure.
CAUTION: To avoid over-inflation, never exceed the recommended pressure on articles to be inflated. Bursting can cause serious injury.
NOTE: The air compressor has a pressure switch (cut on at 130 PSI, cut off at 155 PSI) to protect it from over-pressure damage. The switch automatically turns off the motor at 155 PSI and restarts when pressure drops below 130 PSI.
Tire Deflation:
- With the inflation option connected to the tire inflation gun, press the bleeder valve button on the tire gun kit to decrease tire pressure.
- When desired pressure is reached, release the bleeder valve button to halt deflation.
IMPORTANT: Ensure the compressor sits upright while operating. Do not operate in any other position. Avoid tugging the compressor to move it; instead, move it to the same side of the vehicle as the tires being aired up.
Always ensure the Portable Compressor's power cord is uncoiled and fully extended when using it to avoid overheating the cord.
Inline Pressure Gauge:
- The pressure gauge on the inflation gun provides convenient tire pressure monitoring when airing up or down (it does not measure airflow). This eliminates switching between a tire chuck and a pressure gauge.
- Please note that during inflation and deflation, due to air velocity, the pressure gauge may not provide perfectly accurate readings. Release the lever on the tire inflation gun during inflation to check tire air pressure.
NOTE: To release excess pressure, turn off the compressor and disconnect the hose. With the tire inflation gun still connected to the coil hose, pull the trigger on the tire inflation gun to release excess pressure.
450P-RV Automatic Accessories
- 45-Degree Extended Reach, Angled Chuck: Open-ended air chuck allows reach into areas difficult to reach by hand. Connects to the Tire Inflation Gun.
- 90-Degree Twist-on Chuck: This open-ended air chuck can be attached to any inflation valve where there is limited clearance.
- Primary Hose & Extension Hoses: Dual hoses, with quick connect couplings.
- Tire Inflation Gun: Normally closed-ended chuck (until lever is engaged). All air chucks attach to the Tire Inflation Gun with quick connect couplings.
Safety Precautions
- 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.
- Never exceed 20 M.P.H. when driving with partially inflated tires.
- Never make sharp turns while driving with reduced tire pressure.
- Re-inflate tires before high-speed traveling onto roadways.
- Use heat-resistant, minimum 200 PSI-rated working pressure extension hose. Do not use aftermarket hoses with less than 200 PSI working pressure, as some may not be suitable due to heat and pressure generated by this type of air compressor.
CAUTION: Never touch the air compressor or fittings connected to it (other than the ON/OFF switch) with bare hands during or immediately after use. The extension hose and fittings will become very HOT. If necessary, wear heat-resistant gloves to remove the hose from the compressor quick connect stud.
Maintenance & Repairs
Your air compressor is equipped with a permanently lubricated, maintenance-free motor. Never try to lubricate the compressor. Regularly clean dust and dirt from the compressor cooling fins and motor housing. All repairs should be performed by the manufacturer or manufacturer-authorized service agencies only.
