OPERATING INSTRUCTIONS
Please read and follow the operating instr ctions
caref lly to ass re that yo will enjoy the convenience
and best se o t of yo r air compressor.
IMPORTANT:
1. Always operate the compressor at or BELOW THE
MAXIMUM PRESSURE RATING of the compressor. Refer
to the Specifications section of this man al for details.
2. Always OBSERVE THE MAXIMUM DUTY CYCLE of the air
compressor. Refer to Specifications section of this
man al for details. Operation exceeding maxim m
press re ratings and/or d ty cycle will res lt in damage to
the air compressor.
3. Yo r air compressor is eq ipped with an AUTOMATIC
THERMAL OVERLOAD PROTECTOR. This feat re is
designed to protect the air compressor from over-heating
and ca sing permanent damage to yo r air compressor.
The thermal overload protector will a tomatically sh t off
power to the air compressor sho ld internal operating
temperat re of the air compressor rise above safe levels
d ring excessive se.
4. Sho ld at any time d ring se, yo r air compressor
a tomatically sh ts off - do not attempt to restart. T rn
ON/OFF switch of air compressor to the OFF position. The
a tomatic thermal overload protector will a tomatically
reset when internal temperat re of the air compressor
drops below safe level. After allowing air compressor to
cool off for abo t 30 min tes, yo can safely res me se
of the air compressor by t rning the air compressor back
on.
5. Please note that yo may experience a slight delay (abo t
½ second) of the compressor’s motor starting when the
ON/OFF Switch is t rned ON while compressor is
press rized (when there is press re in the line that the
compressor is connected to). This is a normal delayed
reaction, not a Compressor ON/OFF Switch malf nction.
6. It is recommended that yo keep the vehicle’s engine
r nning while sing the air compressor to prevent
discharge of yo r vehicle’s battery. ONLY OPERATE THE
AIR COMPRESSOR IN WELL VENTILATED AREAS.
Compressor performance is enhanced when operating
compressor with vehicle engine r nning.

TIRE INFLATION & DEFLATION
IMPORTANT: Before attaching air compressor’s
power cord to power so rce, check to make s re that
the ON/OFF switch of yo r 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. Keep yo r vehicle engine r nning while
operating compressor to avoid draining yo r
vehicle’s battery.
CAUTION: Yo r Portable Air Compressor is D st
and Moist re Resistant, b t NOT DUST OR
WATERPROOF. Never place compressor in soft sand
while r nning the compressor. Vibration from the
compressor will ca se the compressor to settle into
soft sand, res lting in compressor drawing in foreign
particles. Never expose compressor to water while
r nning the compressor.
IMPORTANT: Make s re compressor sits pright
while operating compressor. Avoid t gging at
compressor. Instead, move the compressor to the
same side of the vehicle as the tires that are being
aired p.
IMPORTANT: Always make s re the Portable
Compressor’s 8ft. power cord is ncoiled and f lly
extended when sing yo r air compressor to avoid
overheating the power cord.

5-in-1 INLINE
INFLATOR/DEFLATOR HOSE
OPERATION INSTRUCTIONS:
This air compressor comes with 3/8” q ick connect
st d. Yo r Inline Deflator comes with extension coil
hose with 3/8” q ick co pler. Simply attach this
m lti-f nction extension coil hose to the 3/8” q ick
connect st d and yo are ready to inflate tires. The
Inline Deflator/Inflator Hose can be sed for both
Airing Up and Airing Down. Please familiarize
yo rself with the following different f nctions of this
versatile air tool:
A. TIRE INFLATION:
1. Attach q ick connect co pler to air compressor.
2. P sh the tire ch ck, with the lever in the pright
position, down over the tire valve stem and then
p sh the lever down to the horizontal position to
lock in place.
3. Check to make s re the Deflator Collar Lock is
disengaged.
4. T rn compressor switch on to begin inflation.
When desired press re is reached, t rn
compressor off.
B. HANDS FREE CONTINUOUS DEFLATION:
1. P sh the tire ch ck, with the lever in the pright
position, down over the tire valve stem and then
p sh the lever down to the horizontal position to
lock in place.
2. P sh Deflator Collar toward tire valve stem and
t rn Deflator Collar clockwise to engage lock.
3. When desired press re if reached, t rn Deflator
Collar co nterclockwise to disengage lock.
C. INTERMITTENT DEFLATION:
1. The intermittent deflation f nction offers fast
downward press re adj stments.
2. With tire ch ck attached to tire valve stem, p sh
Deflator Collar toward tire valve stem to decrease
tire press re.
3. Release Deflator Collar to halt deflation.
D. INLINE PRESSURE GAUGE:
1. The 2-inch Inline Press re Ga ge provides
convenient tire press re monitoring when airing
p or down. This eliminates switching back and
forth between tire ch ck and tire press re ga ge.
2. Please note that d ring inflation and deflation,
d e to air velocity, the press re ga ge cannot
provide acc rate tire press re readings.
Momentarily halt inflation or deflation to obtain
acc rate tire press re readings.

SAFETY PRECAUTIONS
1. Always inflate tires to man fact rer’s
recommended tire press res. Exercise extreme
ca tion when driving with aired-down tires.
2. Never exceed 20 M.P.H. when driving with
partially inflated tires.
3. Never make sharp t rns while driving with
red ced tire press re.
4. Re-inflate tires before high speed traveling onto
roadways.
5. Only se heat-resistant, minim m 200 PSI-rated
working press re extension hose. Some
aftermarket hoses may not be s itable for se
with this air compressor d e to heat and
press re typically generated by this type of air
compressors.
6. Use of a close-ended tire ch ck will ca se
excessive press re b ild p if the tire ch ck is
not attached to tire valve stem while air
compressor is in operation.
7. IMPORTANT: Always se an Open-Ended tire
ch ck s ch as the tire ch ck eq ipped on the
Inflator/Deflator Coil Hose for tire inflation.
CAUTION: Never to ch the air compressor or
fittings connected to the air compressor with bare
hands d ring or immediately after se. The fittings on
extension hose will become very HOT d ring se. If
necessary, wear heat resistant gloves to remove
extension hose from primary hose.
MAINTENANCE & REPAIRS
1. Yo r air compressor is eq ipped with a
permanently l bricated, maintenance-free motor.
Never try to l bricate the compressor.
2. Reg larly clean d st and dirt from compressor
cooling fins and motor ho sing.
3. Only the Man fact rer or Man fact rer
a thorized service agencies sho ld perform
repairs.
