Set up
The emission control system for this Compressor’s Engine is warranted for standards set by the U.S. Environmental
Protection Agency and by the California Air Resources Board (also known as CARB). For warranty information, refer to
the engine manual.
Mounting to a Truck bed
1. Before mounting, if needed, reinforce the area with plywood or steel plating.
2. With assistance, move the compressor to the truck bed location and mark the floor of the truck bed through the holes
in the compressor’s feet. Check for any hidden wiring or cables and adjust the location for the holes as needed. Then,
temporarily set the compressor aside.
3. Drill the four 1/2” diameter holes through the truck bed and any reinforcing materials.
4. Set the compressor back in place, and align the foot holes with the pre-drilled holes. Use four 1/2” diameter, bolts,
washers and lock washers (all not included) to secure the compressor in place.
Assembly
To install the Air Filter Assembly (84), fit the Connector into the
Air Filter Assembly and slide the assembly into the hole on the
side of the First Stage Cylinder Head (61). Secure in place with
the Wing Nut.
break-In Compressor
Break in the new Air Compressor as follows:
a. Make sure the engine is off. Open the air outlet valve on the left side of the tank.
b. Check all fluid levels in the engine and pump.
c. Start the engine following the General Operating Instructions.
d. Let the unit run for 30 minutes. Air will expel freely through the Coupler.
e. Turn OFF the engine.
f. Remove the male coupler.
Connection
Connect a regulator valve, an in-line shut off valve and a 1/2” NPT air hose (all sold separately) to the Quick
Coupler. The air hose must be long enough to reach the work area with enough extra length to allow free movement
while working.
Note: An in-line shutoff ball valve is an important safety device because it controls the air supply even if the air
hose is ruptured. The shutoff valve should be a ball valve because it can be closed quickly.
1. Depending on the tool which you will be using with this compressor, you may need to incorporate additional
components, such as an in-line oiler, a filter, or a dryer (all sold separately). Consult your air tool’s manual for needed
accessories. See Typical Air Line Setup charts on the following pages. This is a truckbed compressor, so use the
portable setup as a model.
