SAFETY INSTRUCTIONS
Do not attempt to disassemble, repair or customize this product.
Avoid setting up any parts of this product where there is a risk of falling off or risk of coming in contact with water.
Avoid reaching out to touch or pick up any fallen or water submerged parts.
Never leave this product unattended during use.
Intended for use by adults only.
During and immediately after use, avoid touching any part of the compressor with bare hands as it is very hot
during such periods.
Avoid use of product near flames, explosive materials, aerosol products or oxygen devices.
Be sure to pump nothing other than atmospheric air.
It is important to determine the maximum air pressure for any tool or attachment before using it.
Air sprayer or nozzle should always be pointed away from any part of the body.
The compressor has Thermal Overload Protection, if this protection activates, cut off the source of power and let
the unit cool down for about 30 minutes. This will reset the system and allow you to safely resume use of the air
compressor.
Make sure your battery ground is detached and the tank has no pressure before you begin the installation.
Employ equipment for eye protection during drilling operations.
Ensure that your air system has no pressure before you begin.
The specific voltage requirement for this air on-board system is 12 volt DC, therefore installation must be done to
a DC power source of 12 volts.
PLANNING YOUR INSTALLATION
Before beginning the installation, determine each component’s spot.
Confirm you have the proper length of airline and wire.
Power wire to compressor should be kept short.
To power up the air compressor, make sure you use a 12-gauge wire or thicker.

COMPRESSOR
MOUNTING
Determine a dry place to mount your compressor. If you have chosen to install in the engine compartment,
you should mount it as close to the front as possible to allow for maximum flow of air around compressor and
also to avoid heat from the exhaust. IMPORTANT: Never attach the compressor to any plastic or other
flexible material.
For optimal results, the compressor should be placed as close to the battery as possible. This will reduce the
amount of wiring needed.
Avoid placing compressor near flammable liquids.
If you are planning to move compressor’s air intake to an area other than where the compressor was
installed, make sure your placement allows for the airline to be routed from the air inlet of the compressor to
the remote inlet air filter.
Mark the spots for the holes with the mounting base as a guide and then drill. Make sure the compressor is
secured.
To enhance performance and make sure the battery of your vehicle doesn’t discharge, keep the engine
running while the compressor is being used.
BRAIDED HOSE INSTALLATION
Connect the stainless steel braided hose of the compressor to the tank’s inlet port.
IMPORTANT: The tank’s inlet port must be 3/8" N.P.T. (National Pipe Thread).
REMOTE AIR FILTER INSTALLATION KIT
Only use if you need to move compressor’s air intake to an area other than where the compressor was installed.
A. Braided Hose Bracket with Self-Anchoring Pin (1 pc)
B. 3/8" NPT Female x 3/8" Barbed Tube Fitting (1 pc)
C. 3/8" NPT Male x 3/8" Barbed Tube Fitting (1 pc)
D. 3/8" OD Air Line (1 pc)
E. Air Line Clips (3 pcs)
F. Air Line Clips Screws (3 pcs)
G. Remote Inlet Air Filter with Filter Element (1 pc)
H. Remote Filter Holder with Self-Anchoring Pin (1 pc)
I. Filter Elements (2 pcs)
J. Remote Filter Holder Screws (2 pcs)
10 feet of air line is enclosed for attaching the remote air filter.
Find an installation location for the remote air filter, ensuring that the location should be dry and far from a
heat source.
Use a hose cutter, a razor blade, or a sharp knife when trimming the airline. A clean, square cut is optimal.
IMPORTANT: Do not use wire cutters or scissors to cut the air line, these tools may flatten or crimp the air
line causing it to leak.
Place the airline all the way onto the barbed fittings or at least, until it covers two ridges and starts routing the
air line.

AIR TANK
MOUNTING
Find a convenient mounting location in your vehicle for the air tank. Ensure ports are reachable before drilling
any holes.
Attach both brackets to the tank using the provided screws.
Mark the location of holes using the mounting brackets of the air tank as a template, and then drill to size.
Using four screws (not provided), secure the air tank. IMPORTANT: Do not mount on a flexible material.
PORT LOCATIONS AND THREAD SIZE (NPT)
PRESSURE SWITCH RATING
The included pressure switch has a rating of 170 PSI ON, 200 PSI OFF. When the air pressure in the air tank
is below the preset ON pressure (170 PSI), the compressor will automatically turn on and will start pumping
air into the tank. When the pressure reaches the cut OFF pressure (200 PSI), the compressor will be
automatically shut off.
DRAIN VALVE
This valve helps you drain the water that can collect in the air tank after long periods of use.
REMOVING CONDENSATION:
To remove any condensation which has accumulated inside the tank, bleed the tank’s pressure until it ranges
from approximately 5 PSI to 20 PSI.
Remove the drain valve found at the tank’s bottom to drain the water from the tank. After draining the
accumulated condensation, reinstall the drain valve.
IMPORTANT: Draining the system regularly will extend the life of the air tank.
MAINTENANCE
Make sure that electrical and fitting connections are regularly inspected, cleaned and tightened when needed.
Make sure mounting screws are regularly tightened if needed.
Drain weekly, to avoid excessive buildup of condensation.
Compressor features a washable air filter which should be cleaned using any mild form of liquid soap every
two months if it gets dusty. Just remove the front cover of the filter’s housing to reach it. Replacement time
frames depend on the operating environment and how often it is used.
Clean dirt and dust from heat spreader and motor housing of the compressor.
The motor of the air compressor has a maintenance-free lasting lubricant. DO NOT LUBRICATE.

ELECTRICAL CONNECTION
COMPRESSOR
The red wire of the compressor should be connected to (+) 12-volt power source. IMPORTANT: To prevent
the compressor from over running and possible damage due to an air leak, connect the compressor’s red wire
to a power source in the vehicle that only gets power when the vehicle’s ignition is on. Recommended
connection points are: windshield wiper motor, blower motor or an accessory terminal on the fuse panel.
Make sure to use wire that is as heavy as the wire of the compressor and to use the included fuse for circuit’s
protection.
Attach the black wire to any of the Pressure Switch’s connections located on the air tank.
The remaining Pressure Switch connection should be attached to ground. Secure the end to any metal body
or to the negative side of the vehicle’s battery. The ground connection should be rust and paint free.
Your compressor is now set for use and will turn on automatically when air pressure in the air tank falls. When
air pressure reaches maximum PSI, it will turn off. If the compressor fails to reach the maximum air pressure
of the tank, which is the Pressure Switch's cut OFF pressure, check all air connections for leaks. While the
compressor is pumping, use soapy water or any bubble solution to perform this check. In case the leak
remains after tightening, re-apply thread sealant.
