STEP 1 - PREPARE THE VEHICLE
Remove the negative terminal on the battery.
STEP 2 - PREPARE THE COMPRESSOR
Install the rubber isolator feet onto the compressor mounting
brackets. Insert the brass sleeves into the top of the isolator feet, see
Figure "B". Install the compressor T-fitting into the threaded
exhaust port on the compressor head, see Figure "A". Tighten the
fitting sufficiently to engage the pre-applied orange thread sealant.
(Torque to 40 in. lbs.) DO NOT OVERTIGHTEN THE FITTING.
InstallthepressureswitchintothecompressorT-fitting. Installtheair
filter into the threaded inlet port on the compressor head (finger
tight). Installthe positive(red) wirefrom thecompressor ontoeither
spade on the pressure switch, see Figure "A".
STEP 3 - MOUNT THE COMPRESSOR
Selectaconvenientlocationtomountthecompressor. Thislocation
shouldprovideampleairflowandbeprotectedfromairbornedebrisand
moisture. The mounting surface should be rigid to support the compressor, such as under the hood on a fender well
or in a vented storage compartment. The compressor is oil-less and can be mounted in any orientation necessary for
installation.
Usingthe compressor as a template, center punch, and drill three 3/16" holes. Before drilling, ensure that thereare
no electrical , fuel, or brake lines on the opposite side of the mounting surface that can be damaged by the drill. Any
burrsintheholesshouldberemovedtopreventdamagetotherubberisolators. Mountthecompressorusingthesupplied
10 -32 x 1" machine screws, 10 -32 lock nuts, and 3/16" washers. SeeFigure "B". Maximum vibration isolation can
be achieved by properly mounting the compressor. The machine screw and nut should be tightened only enough to
bottom-out the brass insert, see Figure "B". DO NOT OVERTIGHTEN. Overtightening will crush the brass insert
andtherubberisolator,thereby reducing vibrationisolation.
Attach the black wire from the compressor to a grounded component of the vehicle's chassis.
STEP 4 - MOUNT THE AIR TANK

theairtankintothemountingsurface.SeeFigure"A". Ensureclearaccesstothefittingsontheairtankismaintained.
Do not exceed 120 psi in the tank.

STEP 6 - ROUTE THE AIR LINE TUBING
Routealengthofairlinetubingfromthepush-to-connectfittingon
the air tank to the T-fitting on the compressor. See Figure "A".
Route a length of the airline tubing from the tank to the bulk head
fitting,seeFigure"A".Routetheairlinetoavoidsharpedgesorheat
fromtheengineor exhaust system. Using arazorknife,makethe cut
as square as possible and push the air line into the fittings as far as
possible. Do not fold or kink the air line tubing.
STEP 7 - WIRE THE SYSTEM
Strip1/4"offtheendof the red 14 gage wire supplied withthekit.
Crimp a female spade connector onto the end of the red wire. Install
thefemalespadeconnector onto theremainingspadeonthe pressure
switch. Usingawireconnector,attachtheoppositeendofthewireto
an ignition activated, positive 12 Volt, 25 Amp minimum power
source. Consult the manufacturer's wiring diagram for your
vehicle. Slip the wire connector over the existing ignition activated
wireandinserttheun-stripped14gagewireintotheconnector. Close
the wire connector over the wires with pliers, see Figure "C".
Install an in-line fuse in the 14 gage power wire, as close to the
power source as conveniently possible. Cut the 14 gage wire and
inserttheun-stripped ends intothefuseholder. Closethefuseholder
with pliers and insert a 25 Amp blade fuse. See Figure "D".
NOTE: Shouldadditionalwirebenecessary,14gagemultistrand
wire may be used.
STEP 8 - TEST THE SYSTEM
Re-attachthenegativeterminalonthebattery.Turnonthevehicle'signition. Theaircompressorwillrunforashort
time to build pressure in the tank. Once the pressure reaches 120 psi in the air tank, the pressure switch will turn the
compressor off. It will not restart until the pressure in the tank drops below 90 psi.

FILTER MAINTENANCE
It is recommended that the air compressor filter be inspected periodically. If the filter is sufficiently clogged with
road debris or moisture, it will require replacement.
