450P-RV AUTOMATIC PORTABLE COMPRESSOR
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.
