.
The following warnings indicate a potential
hazardous situation that could result in
death or serious injury.
READ ALL INSTRUCTIONS before operating product. Failure to
follow all instructions below may result in electrical shock, fire and
serious injury or death.
SAFETY GLASSES: Always wear ANSI Z87.1 approved safety
glasses with side shields when operating unit. Compressed air and
particulate matter can cause eye and soft tissue damage. Keep air
stream away from skin and eyes.
RISK OF BURNS: Always wear gloves. Some exposed parts may
become hot during use.
RISK TO BREATHING: This compressor is not designed for and
should never be used as a source of breathable air. The air stream
may contain carbon monoxide, toxic vapors or solid particles.
Breathing these contaminants can cause serious injury or death.
RISK OF ELECTRIAL SHOCK: This compressor is for use in dry
conditions only.
RISK OF FALLING: This compressor will produce vibrations and
can “walk.” Only operate dry level ground.
RISK OF FIRE: This unit will become hot during operation. Allow to
cool before storing. NEVER operate the unit in an explosive
atmosphere or near combustible material. An explosion or fire
could result causing severe bodily harm or even death.
RISK OF BURSTING: Use only accessories rated for 120 psi.
Always follow the manufacturer’s recommended inflation
instructions for your item.
DO NOT MODIFY: Never drill, modify or attempt to repair the unit.
There are no user serviceable parts inside.
SAFE HANDLING: Never carry the unit by the hose or power cord.
Wash hands after use.
PAY ATTENTION: Do not leave the unit running unattended.
SECURE THE LOCATION: Only operate this unit with the vehicle
in a level, dry location, well off the roadway and safe from traffic.
Be sure to stay out of the travel lane.
SECURE THE VEHICLE from moving. Always apply the parking
brake and put car into "Park" position. Be aware that even on level
ground as you inflate a tire you could cause the vehicle to rollaway.
It is recommended that you curb and block the tires as an extra
safety precaution against rollaway incidents.
FOR BEST PERFORMANCE: It is recommended that you
operate this unit with your vehicle’s engine running, outdoors and
in a well-ventilated area. NEVER run your engine indoors, in
confined spaces or in unventilated areas. Injury from carbon
monoxide poisoning and death can occur.
CARBON MONOXIDE: Gas is a deadly, colorless, odorless,
poisonous gas produced by gas and diesel engines which can kill
you!
PROPER INFLATION: It is recommended that you always use a
second pressure gauge to verify the actual pressure inside the tires.
Set tires to the vehicle manufacture’s recommended tire pressure. If
you are unsure, contact the manufacturer.
LEAD ACID BATTERY PRECAUTIONS AND SAFETY: Never
smoke or allow a spark or flame in the vicinity of the battery or
engine. Batteries generate explosive gases!
Wear complete eye protection and clothing protection when working
with lead-acid batteries.
Make sure someone is within range of your voice or close enough to
come to your aid when you work with or near a lead-acid battery.
Have plenty of fresh water and soap nearby for use if battery acid
contacts skin, clothing, or eyes. If battery acid contacts skin or
clothing, wash immediately with soap and water.
Avoid touching your eyes while working with a battery. Acid particles
(corrosion) may get into your eyes! If acid enters your eye,
immediately flood eye with running cold water for at least 10 minutes.
Get medical attention immediately.
Remove all personal metal items such as rings, bracelets, necklaces,
and watches when working with a lead-acid battery. A lead-acid
battery can produce a short circuit current high enough to weld a ring
(or the like) to metal, causing a severe burn.
Take care not to drop a metal tool or other metal onto the battery.
Metal may cause sparking or short circuit the battery or another
electrical device. Sparking may cause an explosion.
NOTICE: Notice indicates important information that if not
followed, may cause damage to the equipment.
FREE FLOW OF AIR: This unit is designed to supply a continuous
flow of air. Never dead end the hose or use an accessory that stops
the free flow of air. Damage to the unit can occur.
SMALL ITEMS: Will inflate quickly and can easily be damaged. Pay
special attention to bicycle tires. They inflate very fast and can
rupture. Be prepared to stop the unit quickly when manufacturer’s
recommended inflation pressure is reached.
TURN OFF: All accessories and radios. Unplug any cigarette-lighter
accessories such as cell phones, radar detectors, etc. As a voltage
spike through the electrical system can damage these gadgets.
OPERATING TIME: For best results it is recommend that you use
with an on/off cycle time of 15 minutes, rest/off for every 15 minutes
of run time.
ACCESSORIES: The accessories provided with this unit are the only
items for use with this tool. See Fig. 2 below.
*Sport Ball Needle: Always moisten the inflation needle before you insert it into the valve.
Preferably, use some silicon oil to moisten the needle. Some people use spit...that’s gross.
*Small and Large Extension Adapter: For inflating pool toys, rafts, beach balls and other
items that have manual inflation valves.
*Air Chuck extension: For converting the EZ twist inflator end to a universal lever end. Not
included with all models. Can be purchased at: MasterFlowAir.com

Operating Instructions:
This unit can be operated with the engine on or off.
It operates like any other battery powered tool drawing power from
the battery. Its performance will vary with the battery’s state of
charge. Actual operating time available with the engine off will vary
depending on your battery’s size, age, temperature and state of
charge. Typically with the engine running the charging system will
provide slightly more voltage to the unit thereby increasing the unit’s
performance.
Unpack the unit and completely un-wrap the power cord and inspect
for damage. Place the unit on a dry, level surface.
Connect the air supply hose to the unit using the quick connect
fitting as shown in Fig. 3 below.
1. Slide the retaining snap ring back.
2. Slide the fittings together firmly.
3. While holding fittings together firmly slide the outer ring forward to
lock . See image below.
4. Install the red air filter housing as shown below. Only tighten by
hand.
WARNING
This compressor connects directly to a 12-Volt power source. It is
recommended that you ALWAYS CONSULT YOUR OWNERS
MANUAL FOR VEHICLE SPECIFIC INSTRUCTIONS FOR
LOCATING THE CORRECT ATTACHMENT POINTS.
Take care to avoid moving parts such as fan blades.
5. Identify the battery posts as either POSITIVE (+) or NEGATIVE
(-). Positive posts or terminals are typically bigger than negative
posts or terminals. Some vehicles have a positive terminal to hook
the cable to that is not actually on the battery itself. Connect the
positive cable to the positive terminal of the battery.
6. Attach the black / negative cable to the engine block or alternator
mounting-bracket of the vehicle, as far from the battery as possible.
Do not connect the negative cable to the negative terminal of the
discharged battery, as this can generate a spark, which could cause
the battery to explode.
7. Test the connections by switching the compressor to “on” and air
will begin to flow.
8. Connect the valve adapter to the threaded section of the tire valve
or one of the accessories provided in Fig 2.
9. Switch the unit “On” to begin inflating. Switching the unit off to
observe the gauge will provide the most accurate pressure reading.
Remove the inflator from the item when the manufacturer’s
recommended pressure has been achieved. Confirm the pressure is
correct with a second gauge.
10. Allow the unit to cool, remove the hose and Air filter. Repack in
the original box to prevent damage during storage. Store in a dry
location.
Troubleshooting:
In the event the unit fails to operate:
Check your connections:
Be sure the battery clips are seated securely with a firm “bite” on
the battery terminal and connection point.
Inspect the fuse:
WARNING:
Disconnect the cables from battery prior to inspection and removal
of the fuse. Located on the power cord you will find a black plastic
fuse holder containing a ATC 20A Standard Blade Automotive type
fuse. Carefully remove the cover. Remove and visually inspect
the fuse. If it's blown, you'll see a melted "bridge" going between
the two blades. See the circle in the image below. Replace if
necessary.
Good Bad
Read this it’s very important: When replacing the fuse be sure
both metal blades are inserted into the metal connectors inside the
fuse holder not alongside.
Air leaking from EZ twist inflator:
Inspect the end of the inflator for dirt and check your valve stem for
damage. Also check that the rubber seal inside the inflator end is
not damaged.
Seen here is how the inflator end should look.
Note the rubber seal around the air slot.
