SAFETY PRECAUTIONS:
1. Always inate tires to manufacturer’s recommended tire pressures. Exercise extreme caution
when driving with aired-down tires.
2. Never exceed 20 M.P.H. when driving with partially inated tires.
3. Never make sharp turns while driving with reduced tire pressure.
4. Re-inate tires before high speed traveling onto roadways.
5. Only use heat-resistant, minimum 200 PSI-rated working pressure extension hose.
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.
6. Use of a close-ended tire chuck will cause excessive pressure buildup if the tire chuck is
not attached to tire valve stem while air compressor is in operation.
IMPORTANT: Always use an Open-Ended tirechuck such as the tire chuck equipped on the
Inator/Deator Coil Hose for tire ination.
CAUTION: Never touch the air compressor or ttings connected to the air compressor other than
the ON/OFF switch with bare hands during or immediately after use. The extension hose and ttings
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 ns
and motor housing. All repairs should be performed by Manufacturer or Manufacturer authorized
service agencies only.
440P 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 the Specications section of this manual for details.
2. Always OBSERVE THE MAXIMUM DUTY CYCLE of the air compressor. Refer to Specications
section of this manual for details. Operation exceeding maximum pressure ratings and/or duty
cycle will result in damage to the air compressor.
3. 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 to your air compressor. The thermal overload protector will automatically shut off power
to the air compressor should internal operating temperature of the air compressor rise above safe
levels during excessive use.
4. Should at any time during use, your air compressor automatically shuts off - do not attempt to
restart. 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 the air compressor back on.
5. Please note that you may experience a slight delay (about ½ second) 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.
6. It is recommended that you 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 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 3/8” quick connect stud. Your Inline Deator comes with
extension coil hose with 3/8” quick coupler. Simply attach this multi-function extension coil
hose to the 3/8” quick connect stud and you are ready to inate tires. The Inline
Deator/Inator Hose can be used for both Airing Up and Airing Down. Please familiarize
yourself with the following different functions of this versatile air tool:
TIRE INFLATION:
1. Attach quick connect coupler to air compressor.
2. Push the tire chuck, with the lever in the upright position, down over the tire valve stem and then
push the lever down to the horizontal position to lock in place.
3. Check to make sure the Deator Collar Lock is disengaged.
4. Turn compressor switch on to begin ination. When desired pressure is reached,
turn compressor off.
CAUTION: To avoid over ination, never exceed recommended pressure on articles to be inated.
Bursting can cause serious injury.
USER MANUAL
OPERATING INSTRUCTIONS (cont’d):
HANDS FREE CONTINUOUS DEFLATION:
1. Push the tire chuck, with the lever in the upright position, down over the tire valve stem and then
push the lever down to the horizontal position to lock in place.
2. Push Deator Collar toward tire valve stem and turn Deator Collar clockwise to engage lock.
3. When desired pressure is reached, turn Deator Collar counterclockwise to disengage lock.
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.
INTERMITTENT DEFLATION:
1. The intermittent deation function offers fast downward pressure adjustments.
2. With tire chuck attached to tire valve stem, push Deator Collar toward tire valve stem
to decrease tire pressure.
3. Release Deator Collar to halt deation.
INLINE PRESSURE GAUGE:
1. The 2-inch Inline Pressure Gauge provides convenient tire pressure monitoring when airing up or
down. This eliminates switching back and forth between tire chuck and tire pressure gauge.
2. Please note that during ination and deation, due to air velocity, the pressure gauge cannot
provide accurate tire pressure readings. Momentarily halt ination or deation to obtain
accurate tire pressure readings.
