CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSIG: Pounds per square inch gauge; a unit of measure of pressure.
Code Certification: Products that bear one or more of the following marks:
UL, CUL, ETL, CETL, have been evaluated by OSHA certified independent
safety laboratories and meet the applicable Underwriters Laboratories
Standards for Safety.
Unloader Blow-Off Pressure: All models are continuous running units
controlled 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.

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
provide 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
compressed air. Regardless of its indicated pressure
rating, plastic pipe can burst from air pressure. use only metal pipe for air
distribution.
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.
Air Compressor
The air compressor pump was filled WITH oil at the manufacturer. Check air
compressor pump oil level before operating unit. If necessary, fill pump to the
appropriate level with approved compressor oil, see the Maintenance section of
this manual for details.

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 shown): To compress air, the pistons move up
and down in the cylinders. On the downstroke, air is drawn in through the air
intake filter and then through the air intake valves. The exhaust valve remains
closed. On the upstroke of the piston, air is compressed. The intake valves
close and compressed air is forced out through the exhaust valve, through the
outlet tube, through the check valve and into the air tank. Working air is not
available until the compressor has raised air tank pressure above that required
at the air outlet.
Throttle Control (not shown): A throttle control has been incorporated as an
extra feature. When maximum tank pressure is reached and the unloader valve
unloads air, it also activates a throttle control on the engine. This gas saving
feature 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
accelerates the engine to full throttle.
Tank Pressure Gauge: The tank pressure gauge indicates
the reserve air pressure in the tank.
Unloader Valve: All models are continuous running
outfits controlled by tank pressure. When the
maximum tank pressure is obtained, the unloader
valve will exhaust the compressed air to the
atmosphere (blow-off). When the pressure drops to a
predetermined point, the unloader valve closes and
causes the tank pressure to increase.
Safety Valve: If the unloader valve does not shut off the
air compressor at or near its cut-out pressure setting,
the safety valve will protect against high pressure by
"popping out" at its factory set pressure (slightly higher
than the unloader blow-off setting).

Shut Off Valve: Opens and closes air flow.
Drain Valve: The drain valve is located at the base
of the 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 obstructions. See
"Maintenance".

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.
Open
Page 15
15- ENG
D26805
2. Turn shut-off valve knob into open position.
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.
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 shut-off valve knob. This will allow air to
build pressure in the air tanks.
NOTE: When the air tank is pressurized, the tank pressure 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 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.
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.

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
bursting. 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
unsatisfactory 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
condensation 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. Push down engine stop lever and hold until engine shuts off.
13. Close shut-off valve.
14. Remove the air tool or accessory.
15. Open shut-off valve and allow air to slowly bleed from the tank. Close the
shut-off valve or when the tank pressure is approximately 20 PSIG.
Drain air tank daily. Water will condense in air tank. If not
drained, water will corrode and weaken the air tank
causing 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.
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.

capacity. Before using the compressor pump, check the air filter to make
sure it is clean and in place.
Oil
Drain tank to release air pressure before removing the oil
fill cap or oil drain plug.
Checking
1. Remove the oil fill plug (A). The oil level should be even
with the top of the fill hole and no lower than 6 threads
from the top of fill hole.
2. If needed, slowly add oil until it reaches the top of fill hole.
NOTE: Use an oil specifically formulated for use in an air
compressor, such as Sears 9-16426 air compressor oil.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and drain oil into a suitable container.
3. Replace the oil drain plug (B) and tighten securely
4. Slowly fill crankcase to the top of the fill hole. Crankcase capacity is 16
fluid ounces (473.2 ml).

To Drain Tank
1. Push down and hold engine stop lever until engine shuts off.
2. Remove the air tool or accessory.
3. Pull ring on safety valve allowing air to bleed from the tank until tank
pressure is approximately 20 psi. Release safety valve ring.
4. Drain water from air tank by opening drain valve (counter-clockwise) 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.
5. After the water has been drained, close the drain valve (clockwise). The air
compressor can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be
removed, cleaned, then reinstalled.
Overfilling with oil will cause premature compressor
failure. Do not overfill.
5. Replace oil fill plug (A) and tighten securely.

If it is dirty, replace it with a new filter.
1. Using a pair of needle nose pliers or a screwdriver pull or
pry out the old filter and carefully clean the filter area.
2. Push the new air filter in place. Refer to the "Repair Parts"
for the correct part number.
IMPORTANT: Do not operate the compressor with the air filter removed.
Safety Valve-Replacement
If the safety valve does not work properly, over-
pressurization can occur and cause air tank rupture or
explosion. Daily pull the ring on the safety valve and make sure it operates
freely. If the valve is stuck or does not operate smoothly, it must be
replaced with the same type of valve having an identical pressure rating.
To Remove Safety Valve:
1. Make sure the air compressor unit is off and
disconnect the spark plug wire.
2. Open the shut-off valve and allow all air to bleed
from the tank. Monitor tank pressure gauge as
tank is emptied.
3. When tank is empty, remove safety valve (A) from
manifold.
To Install New Safety Valve:
1. Verify new safety valve is the correct pressure rating
for your air compressor.
2. Verify threads for safety valve in manifold are clean.
3. Apply thread sealant to the threads of new safety valve.
4. Install new safety valve and tighten securely.
5. Reconnect spark plug wire to engine.
Air Compressor Pump Intake and Exhaust Valves
Once a year have a Trained Service Technician check the air compressor pump
intake and exhaust valves.
SERVICE AND ADJUSTMENTS
ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE
PERFORMED BY TRAINED SERVICE TECHNICIAN.

Belt – Replacement and Adjustment
Serious injury or damage may occur if parts of the body or
loose items get caught in moving parts. Never operate the
unit with the belt guard removed. the belt guard should be removed only
when the air compressor is turned off the spark plug wire is disconnected.
Belt Guard – Removal
1. Disconnect the spark plug wire on the engine and release all air tank
pressure.
2. (Refer to figure) Remove the four screws
(A) from the belt guard. The belt guard
can now be removed.
Belt – Replacement
1. Disconnect the spark plug wire on the
engine and release all air tank pressure.
2. Remove the belt guard as previously
described.
3. Mark engine position on saddle.
4. Loosen stiffener bracket screws on engine.
5. (Refer to Figure) Being careful not to remove
the stiffener plate under the saddle, loosen
the six engine mounting bolts (C).
6. Slide engine toward pump to remove
tension from the belt, and then remove the
old belt.
7. Install the new belt over the pulleys.
NOTE: The belt must be centered over the
grooves on the engine pulley and flywheel.
8. Slide the engine back into its regular position. Line the engine up with the
mark made earlier on saddle.
Belt Tension - Adjustment
1. Hold belt tension and securely tighten two engine mounting bolts.
2. Measure correct belt tension. Proper tension is achieved when a three (3)
pound weight or equivalent finger pressure applied midway between the
motor pulley and compressor flywheel causes a 1/4" deflection of the belt
as shown.
3. When proper belt tension is achieved,
tighten the remaining engine mounting
bolts.
4. Tighten stiffener bracket screws.
NOTE: Once the engine pulley has been
moved from its factory set location, the
grooves of the flywheel and pulley must
be aligned to within 1/16" to prevent
excessive belt wear. Verify the alignment
by performing the following Pulley and
Flywheel - Alignment.
5. Replace belt guard.

Pulley and Flywheel - Alignment
The air compressor flywheel and engine pulley must be in-line (in the same
plane) within 1/16" to assure belt retention within flywheel belt grooves. To
check alignment, perform the following steps:
1. Disconnect the spark plug wire on the engine and release all air tank
pressure.
2. Remove belt guard.
3. Place a straightedge against the
outside of the flywheel and the
engine drive pulley. Refer to Figure as
required.
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".
