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.
IMPORTANT:
1. Always operate the compressor AT OR BELOW
THE
MAXIMUM PRESSURE RATI
NG 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 cyc
le 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 causing permanent damage to your air
compressor. The therma
l 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 at any time during use, your air compressor
automatically shuts off, d
o 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 ai
r compressor to cool off for about
30
minutes, you can safely resume use of the air
compressor by turning on the air compressor.
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 strongly recommended that you keep the vehicle’s
e
ngine running while using the air compressor to
prevent discharge of your vehicle’s battery.
7.
ONLY OPERATE THE AIR COMPRESSOR IN WELL
VENTILATED AREAS. Compressor performance is
enhanced when operating compressor with vehicle
engine running.

TIRE INFLATION & DEFLATION
IMPORTANT
: Before attaching air compressor
power cord to power source, 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
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.
IMPORTANT:
Make sure compressor sits upright
while operating compressor. Avoid tugging at
compressor if line is taut. Instead, move
the
compressor to the same side of vehicle as tires tha
t
are being aired up.
IMPORTANT :
Always make sure the Portable
Compressor’s 8 foot
power cord is uncoiled and fully
extended when using your air compressor to avoid
overheating the power cord.

5-in-1 INLINE
INFLATOR / DEFLATOR HOSE
OPERATION INSTRUCTIONS:
This air compressor comes with ¼” quick connect
stud. Your Inline Deflator comes with extension coil
hose with ¼” quick coupler. Simply attach this multi-
function extension coil hose to the
¼” quick connect
stud
and you are ready to inflate tires. The Inline
Inflator/De
flator Hose can be used for both Airing Up
and Airing Down. Please familiarize yourself with the
following different functions of this versatile air tool:
A. 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 Deflator C
ollar Lock is
disengaged.
4.
Turn compressor switch on to begin inflation.
When desired pressure is reached, turn
compressor off.
B. 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 Deflator Collar toward tire valve stem and
turn Deflator Collar clockwise to engage lock.
3.
When desired pressure if reached, turn Deflator
Collar counterclockwise to disengage lock.
C. INTERMITTENT DEFLATION:
1. The intermittent deflation function offers fast
downward pressure adjustments.
2.
With tire chuck attached to tire valve stem, push
Deflator Collar toward tire valve stem to decrease
tire pressure.
3. Release Deflator Collar to halt deflation.
D. INLINE PRESSURE GAUGE:
1. The 2-inch Inl
ine Pressure Gauge provides
convenient tire pressure monitoring when airing
up or down. This eliminates switching back and
forth between a tire chuck and a
tire pressure
gauge.
2. Please note tha
t during inflation and deflation,
due to air velocity, pressure gauge cannot
provide accurate pressure readings.
Momentarily halt inflation or deflation to obtain
accurate pressure readings.

SAFETY PRECAUTIONS
1.
Always inflate tires to manufacturer’s
recommended tire pressures. Exercise extreme
caution when driving with aired-down tires. Re-
inflate 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.
6. The use of a close-
ended tire chuck will cause
excessive pressure buildu
p if tire chuck is not
attached to tire valve stem while air compressor
is in operation.
IMPORTANT:
Always use an Open-
Ended tire chuck such as the
tire chuck equipped on the Inflator/De
flator Coil Hose
for tire inflation when using a compressor without
an
air tank.
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. I
f necessary, wear heat
resistant gloves to remove hose from
the compressor
quick connect stud.
MAINTENANCE & REPAIRS
1.
Your air compressor is equipped with
permanently lubricated, maintenance-
free motor.
Never try to lubricate the compressor.
2.
Regularly clean dust and dirt from compressor
cooling fins and motor housing.
3.
All repairs should be performed by Manufacturer
or Manufacturer authorized service agencies
only.
