Unloader Blow-Off Pressure: All models are continu-

ously running outfits 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 apredetermined point, the unloader valve

closes. The tank pressure will now increase until it

reaches the unloader blow-off pressure.

020396 Rev 02/16/00

You have purchased an air compressor unit consisting of

a 2 cylinder, single-stage air compressor pump and air

tank. Included with portable compressors are wheels,

gauges, and handle.

Your air compressor can be used for operating paint spray

guns, air tools, caulking guns, grease guns, air brushes,

sandblaster, or inflating tires and plastic toys, spraying

weed killers, insecticides, etc.

An air pressure regulator is usually required for most of

these applications. Regulators can be purchased from

most Sears stores or through the Sears Power Tool

Catalog.

Separate air transformers which combine the functions or

air regulation and/or moisture and dirt removal should be

used where applicable.

Figure 1

Air Compressor Pump: 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 airtank pressure

above that required at the air outlet.

Throttle Control: Athrottle control has been incorporated

as an extra feature. When maximum tank pressure is

reached and the unloader valve unloads air, it also

activates athrottle control on the engine. This gas saving

featu re holds the engine at a factory-set idling speed until

air pressure inthe air tank drops to reset pressure; it then

reactivates the throttle control and accelerates the engine

to full throttle.

Unloader Valve: All models are continuously 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 apredetermined point, the unloader

valve closes and causes the tank pressure to increase.

Safety Valve: If the pressure switch does not shut off the

air compressor at or near its cut-out pressure setting, the

safety valve will protect against high pressure by "pop-

ping out" at its factory set pressure (slightly higherthan the

pressure switch cut-out setting).

Check Valve: When the air compressor is operating, the

check valve is "open," allowing compressed air to enter

the air tank. When the air compressor reaches "cut-out"

pressure, the check valve "closes," allowing air pressure

to remain inside the air tank. If the air is not unloaded, the

motor will try to start, but will be unable to. The check valve

allows the motor to restart freely.

Shut Off Valve: Turn the knob counterclockwise to open

the valve and clockwise to close.

2, Attach the rubber feet to the bottom of the foot

extension bracket, Attach foot extension bracket to

the air tank bracket. Use one cap screw, one lock

washer, and one hex nut at each end. Tighten.

3. The leg bracket on the underside of the air

compressor tank has 2 holes on each side for

mounting the wheels. Place one shoulder bolt through

the hole in a wheel. Next, push the bolt through the

LOWER hole ofthe leg bracket and screw on one

hexlocking nut. The special locking nut does not turn

freely. Tighten the nut firmly until it contacts the tan k

leg. See pg. 16. The outfit will sit level if the wheels

are properly installed.

4. Apply teflon tape to the tapered pipe threads on

the adapter and tighten into the manifold. Install the

swivel connection end of the shut-off valve to the

straight threaded end of the adapter (pipe sealant is

not required) and tighten this connection. See photo

below.

It may be necessary to brace or support

one end of the outfit when attaching the

wheels and the foot extension bracket

because the air compressor will have a

tendency to tip before both wheels are

assembled.

Operate the air compressor in a clean, dry and well

ventilated area. The air intake filter must be kept clear

of obstructions which could reduce air delivery of the air

compressor. The air compressor should be located at

least 12" away from walls or other obstructions that

could interfere with the flow of air through thefan bladed

flywheel. The air compressor crankcase and head are

designed with fins to provide proper cooling, if humidity

is high, Sears air filter can be installed to remove

excessive moisture. Closely follow the instructions pack -

aged with the filter for proper installation.

This compressor may be permanently mounted in a

Ioaction such as e truck bed, it desired. A vibration

mount kit is included for this purpose.

1. In order to maintain adequate ventilation for com-

pressor cooling and to avoid contact with pick-up

truck bed, always mount the outfit at least 8" from

any vertical wall. Using the holes in the air tank legs

as a guide, mark and drill four 5/16" diameter holes

in the mounting surface.

2. Insert the vibration mounts in the mounting holes.

Place a flat washer under the mounting surface and

secure each mount with a lock washer and nut. See

Compressors are shipped without oil. Do not

attempt to operate this air compressor without

first adding oil to the compressor pump

crankcase and engine crankcase.

Place unit on a level surface. Remove compressor oil fill

plug and slowly add a special compressor oil such as

Sears compressor oil or SAE-20-20W SF motor oil until

it is even with the top of the oil fill hole. (It must not be

allowed to be lower than 3/8" - 6 threads down - fro m the

top.) When filling the crankcase, the oil flows very

slowly. If the oil is added too quickly, it will overflow and

appear to be full. (Crankcase oil capacity is 16 fluid

ounces.) Under winter-type conditions use SAE 10W oil.

(Multi-viscosity oil - 10W30 - will leave carbon deposits

on critical components reducing performance and com-

pressor life.) Replace oil fill plug.

Remove engine oil fill plug and slowly add oil to the point

of overflowing. Use a high quality oil classified "FOR

SERVICE SC, SD, SE or MS,". See Briggs and Stratton

"OPERATING AND MAINTENANCE INSTRUCTIONS" for

recommended SAE viscosity grades. (Engine crankcase

capacity is 20 fluid ounces.)

For your convenience, purchase a W' NPT nipple 2V2"

long, and a 1/4"NPT x 1/4"NPT coupling (pipe collar) to

allow ease in draining oil. Remove oil drain plug on the

gas tank side of the engine and install the nipple. Thread

the ooupting on the end of the nipple and screw the drain

plug in the coupling. See figure 3.

With the unit in a level position, fill the gas tank (approx.

3/4 gal.) with fresh, clean unleaded gasoline. Regular

gas is an acceptable substitute. Do not use premium

gasoline.

Gasoline Vapor is highly flammable. Refuel

outdoors preferably, or only in well venti-

lated areas. Do not refuel or check gaso-

line level while the engine is running. Do

not store, spill or use gasoline near an

open flame.

A warm engine requires less choking than a cold engine.

Unit is top heavy. Make sure the compres-

sor is stable and will not tip before pulling

the starting cord,

Place your left hand on the air compressor handle,

and your right hand on the starter handle, and pull

cord out quickly to overcome engine compression

and prevent "kickback". If engin e does not start,

push the choke about three-quarters of the way in or

choke level three quarters to the left and pull starter

handle again. When engine starts, push choke in or

choke lever to the left gradually.

Serious damage may result in the following

break-in instructions are not followed.

Pump Break-in: Open the outlet valve to prevent tank

pressure build-up. Run the air compressor for 30

minutes to seat the rings and lubricate all internal

surfaces. This operation must be completed only

once when first putting the unit in service.

After completing the above, and when ready to begin

using the compressor, move the unloader valve

toggle lever to a horizontal position. Close the outlet

valve to build tank pressure.

Engine Break-in: After the first 5 hours of normal

running, change the engine oil. Then after every 25

hours the engine oil should be changed.
