Unloader Blow-Off Pressure: All models are continuous running units con-
trolled by tank pressure. When the maximum tank pressure is obtained, the
unloader valve will blow-off. This will cause the compressor to exhaust the air
to the atmosphere and not the tank. This decreases the load on the engine and
allows it to run at a near no-load condition.
Unloader Reset Pressure: When the tank pressure drops to a predetermined
point, the unloader valve closes. The tank pressure will now increase until it
reaches the unloader blow-off pressure.

D26998
INSTALLATION
Location of the Air Compressor
Exhaust from the gasoline engine contains deadly carbon
monoxide, which is odorless and toxic. Operate engine
only in well ventilated areas.
The air compressor must be operated in a clean, dry, and well-ventilated area.
The air compressor's crankcase and head are designed with cooling fins to pro-
vide proper cooling. The fan blades of the compressor, the flywheel, must be
kept clear of obstructions that could interfere with the flow of air through the air
intake filter.
Do not install the air compressor in a location where heat is excessive. If
the humidity in the operating area is high, an air filter can be installed on the air
outlet adapter to remove excessive moisture. This type air filter is not provided
with this air compressor and must be purchased separately. Closely follow the
instructions packaged with the filter for proper installation.
Do not allow the air compressor to get wet if it is installed
outdoors.
Piping
Plastic or PVC pipe is not designed for use with com-
pressed air. Regardless of its indicated pressure rating,
plastic pipe can burst from air pressure. use only metal pipe for air distri-
bution.
If a pipe line is necessary, use pipe that is the same size as the air tank outlet.
Piping that is too small will restrict the flow of air. If piping is over 100 feet long,
use the next larger size. Bury underground lines below the frost line and avoid
pockets where condensation can gather and freeze. Apply pressure to lines
before underground lines are buried to make sure all pipe joints are free of leaks.

OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Description of Operation
Become familiar with these controls before operating the unit.
Air Compressor Pump (not
D
E
shown): Compresses air into the
C
air tank.
Unloader Valve (not shown):
When the maximum tank pressure
is obtained, the unloader valve will
exhaust the compressed air to the
atmosphere (blow-off). When the
tank pressure drops to a pre-deter-
mined point, the unloader valve
closes and causes the tank pres-
sure to increase.
F
Safety Valve (C): If the unloader valve does not release pressure when tank
reaches "blow-off" pressure, the safety valve will protect against high pressure
by "popping off" at its factory set pressure (slightly higher than the pressure
switch blow-off setting).
Outlet Pressure Gauge (D): The outlet pressure gauge indicates the air pres-
sure available at the outlet side of the regulator. This pressure is controlled by
the regulator and is always less than or equal to the tank pressure.
Tank Pressure Gauge (E): The tank pressure gauge indicates the reserve air
pressure in the tank.
Regulator (F): Controls the air pressure shown on the outlet pressure gauge.
Pull the knob out and turn clockwise to increase pressure and counterclockwise
to decrease pressure. When the desired pressure is reached push knob in to
lock in place.
Drain Valve (not shown): A drain valve is located at the base of each air tank
and is used to drain condensation at the end of each use.
Air Intake Filter (not shown): This filter is designed to clean air coming into the
pump. This filter must always be clean and ventilation openings free from ob-
structions. See "Maintenance".
Throttle Control (not shown): A throttle control has been incorporated as an
extra feature. When maximum tank pressure is reached and the unloader valve
vents air, it also activates a throttle control on the engine. This gas saving fea-
ture holds the engine at a factory-set idling speed until air pressure in the air
tank drops to reset pressure. It then reactivates the throttle control and acceler-
ates the engine to full throttle.

How to Use Your Unit
How to Stop:
1. See the engine manufacturer's manual for the procedure to safely shut
down the gasoline engine. Turning the gasoline engine off will turn off the air
compressor as well.
Before First Start-up
Break-in Procedure
Serious damage may result if the following break-in
instructions are not closely followed.
This procedure is required when:
1. Before the air compressor is used for the first time.
2. When the unloader valve is replaced.
3. When a complete compressor pump is replaced.
The procedure:
1. To prevent pressure from building up in the air tanks during this break-in
period, you must open the unit's unloader valve. Place unloader valve in
“Open” position as shown.
2. Open the pressure regulator. Pull regulator
knob and rotate clockwise until it stops.
3. Start engine. See engine manual supplied by
engine manufacturer for correct procedure.
The air compressor is top
heavy. Make sure the unit is in
a stable position and will not tip before pulling
the starter cord of the engine.
Open
4. Make sure the unloader valve is in the “Open” position to prevent tank
pressure buildup.
5. Run the air compressor for 30 minutes to seat the rings and lubricate all
the internal surfaces. Make sure there is no pressure build up in the tank by
observing the reading on the tank pressure gauge.
6. Place unloader valve in the “Closed” position as shown.
7. Close the pressure regulator. Rotate the regulator
knob counter-clockwise to its built-in stop and
push knob in to lock in place. This will allow air to
build pressure in the air tanks.
NOTE: When the air tank is pressurized, the tank pres-
sure gauge will indicate the pressure available in the air
tank and the gasoline engine will reduce its speed to
idle and keep running. The pressurization of the air tank
will be adjusted automatically by the "reset" and "blow
off" setting of the unloader valve. When the pressure in
Closed
the air tank drops to the "reset" value, the gasoline engine will increase its rpm
to operate the compressor and pressurize the tanks. When the pressure in the
air tank increases to the "blow off" value, the engine rpm will drop to idle.
NOTE: Consult the engine manufacturer's manual for the proper engine
break-in running time and oil change interval for the engine used on your
air compressor as well as other engine maintenance requirements.
12-ENG
D26998
8. Compressed air will be available from the unit's outlet valve until it is used
up or bled off. The compressor is now ready for use.
Before each start-up
Perform the following checks before starting the air compressor.
1. Make sure nothing is blocking the belt guard, air openings, or air filter inlet.
2. Make sure the unloader valve moves freely and smoothly.
3. Check the oil level in the pump and engine, add oil if necessary.
Temperature of muffler and near by areas my exceed
150°F (65°C) avoid these areas.
4. Clean or blow off fins or any part of the air compressor that collects dust
and dirt. The air compressor will run cooler and provide longer service.
5. Open the unloader valve of the air compressor before starting the engine.
To start-up
6. Start the engine (see engine manual supplied by engine manufacturer for
correct procedure) and close unloader to allow tank pressure to pump up to
blow-off pressure.
Unit is top heavy. Make sure the compressor is stable and
will not tip before pulling the starting cord.
Too much air pressure causes a hazardous risk of burst-
ing. Closely monitor the air pressure gauge of the tank so
the maximum pressure limit is not exceeded and monitor the safety valve
to ensure excess pressure is discharged. If pressure continues to build
beyond safe limits, shut the unit down immediately and troubleshoot the
problem.
7. Check all fittings and piping for air leaks. Even minor leaks can cause the
air compressor to overwork, resulting in premature breakdown or unsatis-
factory performance.
8. Check for any unusual vibration and noise.
9. Check for oil leaks and correct any leaks found.
10. Check the pressure ratings of the air tools and accessories being used with
this air compressor before attaching, then adjust the shut-off valve for that
value.
The air compressor's outlet pressure must never exceed
the maximum pressure rating of the tool or accessory
being used. If a pressure regulator is not used, do not use accessories
rated at less than 110 psi.
11. Attach air hose and accessory. Your unit is ready for use.
Compressed air from the unit may contain water conden-
sation and oil mist. Do not spray unfiltered air at an item
that could be damaged by moisture. Some air operated tools or devices
may require filtered air. Read the instructions for the air tool or device.
Shutting Down
12. Turn off engine.
13. Close the pressure regulator.
14. Remove the air tool or accessory.
15. Open pressure regulator and allow air to slowly bleed from the tank. Close
the regulator when the tank pressure is approximately 20 PSIG.
13-ENG
D26998
Drain air tank daily. Water will condense in air tank. If not
drained, water will corrode and weaken the air tank caus-
ing a risk of tank rupture.
16. With tank pressure at approximately 20 PSIG, open the drain valves and
allow moisture to drain.
NOTE: If drain cock is clogged, release all air pressure. The drain cock can
then be removed, cleaned, and reinstalled.
17. After the water has been drained, close the drain cocks. The air compressor
can now be stored.

against the outside of
the flywheel and the
engine drive pulley.
4. Measure the distance
between the edge of
the belt and the
straightedge at points
A1 and A2 in Figure.
The difference between
measurements should be no more than 1/16".
5. If the difference is greater or less than 1/16", loosen the setscrew holding
the engine drive pulley to the shaft and adjust the pulley's position on the
shaft until the A1 and A2 measurements are within 1/16" of each other.
6. Tighten the engine drive pulley setscrew to 70-80 in.-lbs.
7. Visually inspect the engine drive pulley to verify that it is perpendicular to
the drive motor shaft. Points B1 and B2 of Figure should appear to be
equal. If they are not, loosen the setscrew of the engine drive pulley and
equalize B1 and B2, using care not to disturb the belt alignment performed
in step 2.
8. Retighten the engine drive pulley setscrew to 70-80 in.-lbs.
9. Reinstall belt guard.
10. Reconnect spark plug wire to spark plug on engine.

STORAGE
Before you store the air compressor, make sure you do the following:
1. Review the "Maintenance" section on the preceding pages and perform
scheduled maintenance as necessary.
2. Review the "Engine Manufacturer's Operating and Maintenance
Instructions".
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing air to bleed from the tank until tank pres-
sure is approximately 20 psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve on bottom of tank.
Water will condense in the air tank. If not drained, water
will corrode and weaken the air tank causing a risk of air
tank rupture.
6. After the water has been drained, close the drain or drain valve.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, then reinstalled.
7. Wind air hose around hose wrap and secure in place.
8. Store the air compressor in a clean and dry location.
