Eye protection is required to guard against flying fasteners and debris, which could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn. We recommend a Wide Vision Safety Mask for use over eyeglasses or standard safety glasses that provide protection against flying particles both from the front and side. Always use eye protection which is marked to comply with ANSI Z87.1.
Additional safety protection will be required in some environments. For example, the working area may include exposure to a noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided
and used by the operator and others in the work area. Some environments will require the use of head protection equipment. When required, the employer and user must ensure that head protection marked to comply with ANSI Z89.1 is used.
Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection.

FEATURES
KNOW YOUR AIR COMPRESSOR
See Figure 1.
Before attempting to use this product, familiarize yourself with all operating features and safety rules.
DESCRIPTION
Your air compressor is aircooled, splash lubricated, beltdriven, single stage.
DRIVE PULLEYS / FLYWHEELS
Drive pulleys and compressor flywheels must be properly aligned and tensioned to specifications. (Refer to Belt Alignment & Adjustment).
SAFETY VALVES
Safety valves aid in preventing system failures by relieving system pressure when compressed air reaches a pre-determined pressure level. All air receivers must be equipped with an adequately sized safety valve. This type of valve is preset by the manufacturer and must not be modified in any way.
Safety valves are to be placed ahead of any potential blockage point which includes, but not limited to, shutoff valves, heat exchangers, pulsation dampeners, and discharge silencers. Ideally the safety valve should be threaded directly into the pressure point it is sensing, not connected with tubing or pipe, and always pointed away from any chance bystander. All tubing or piping added must be the same size as the safety valve opening or larger.
WARNING!
Excessive compressor RPM’s could cause a pulley or flywheel to shatter, possibly causing bodily harm or death. Do not operate the compressor above the recommended RPM as supplied by the factory.
WARNING!
Safety valves must be provided to protect compressed air systems. Failure to provide properly sized pressure safety valves may cause property damage, severe personal injury or even death.
GUARDS
They must provide protection from moving parts while still allowing full air flow for cooling purposes.
WARNING!
Guards must be fastened in place before starting the compressor. Always stop the unit before removing the guard.
CHECK VALVES
Check valves are designed to allow air to flow freely in one direction only. A properly sized check valve must be provided in the discharge line. Do not rely on a check valve to isolate a compressor from a pressurized tank or compressed air delivery system during maintenance procedures.
PRESSURE REGULATOR KNOB
The pressure regulator knob allows the operator to control the amount of air pressure being supplied to a tool (through the hose). A gauge is provided to indicate the air pressure. To adjust the amount of air pressure supplied: 
Pull up on the regulator knob to unlock it.
Turn the knob clockwise to increase pressure - counterclockwise to decrease pressure.
Push the knob down to lock it into position.
REGULATOR PRESSURE GAUGE
The current line pressure is displayed on the regulator pressure gauge. This pressure can be adjusted by rotating the pressure regulator knob.
COMPRESSOR CONTROLS
Gasoline engine driven compressors are equipped with constant run controls and operate continuously until they are manually shut-off. During operation, air is compressed and delivered to the tanks for use. Once the demand for compressed air is satisfied, the in-line unloader (located in the compressor discharge line) is activated, causing the air delivered by the compressor to be discharged to the atmosphere, and allowing the engine to run at a lower speed. In this state, the system is considered to be “unloaded”. As the air stored in the tanks is used and the demand for compressed air returns, the unloader is deactivated, the engine runs at a higher speed, and the compressed air is once again delivered to the tanks for use.
When starting an engine driven unit with air pressure in the tank, flip the toggle on side of the pilot valve to the horizontal position. This will unload the compressor and allow the engine to start easier.
When the engine has run for a few minutes, flip the toggle back to its original position.
AIR FILTER
This compressor is equipped with an air filter to provide a clean air supply, an essential component to the satisfactory operation of your compressor.
WARNING!
Never locate the compressor where toxic, volatile or corrosive vapors, air temperatures exceeding 104°F, water, or extremely dirty air could be ingested. The compressor could be damaged by these atmospheres and result in injury or death.
10
FEATURES
When using the compressor for spray painting, isolate the compressor as far away from the work area as practical, employing extra air hose rather than an extension cord. Warranty will be void if a failure is determined to be caused by dust, dirt or other contaminants.
COMPRESSED AIR DISCHARGE SYSTEM
WARNING!
Discharge piping can exceed 350°F when compressor is operating. Do not use plastic pipe or lead tin soldered joints for a discharge line. Do not modify the discharge line.
PRESSURE VESSELS
Air receiver tanks and other pressure containing vessels must be equipped with a properly sized pressure relief valve, pressure gauge, and a tank drain. The drain valve must be located in the bottom of the air tank(s) to provide for moisture removal.
WARNING!
Pressure vessels must not be modified, welded on, or repaired. Such actions may cause property damage, severe injury, or even death.
TANK PRESSURE GAUGE
The tank pressure gauge indicates the pressure of the air in the tank.

INSTALLATION
Air compressors should be located in an area that is dry, clean, well lighted, and adequately ventilated.
DANGER!
A gas engine will produce carbon monoxide; always provide adequate ventilation! Do not operate engine in an enclosed area..
Air supplied to the inlet filter must be clean. The compressor belt guard must not be located closer than 12 inches to a wall, or 24 inches to another compressor. Additional safety can be achieved by locating the pulley drive system, with the guard, next to the wall.
The compressor may only be operated in temperatures under 104°F and over 32°F. In cold climates, the compressor should be installed in a heated building.
Proper mounting of the compressor unit is crucial to the safe operation and longevity of the equipment. The installation requires a stable, flat and level surface. Satisfactory results can usually be obtained by mounting the compressor unit on rubber feet supplied with the unit. Refer to Fig. 2.
Uneven feet drawn tightly to a concrete floor or truck bed will cause severe vibrations resulting in cracked welds or fatigue failure. If the unit is mounted to a concrete floor or truck bed or similar foundation, loosen the lock nut several turns & lock it with a back-up nut! The customer

Holding the handle, tilt the compressor toward the drain valve so that it’s set in a lower position.
Open the drain valve completely, allowing the moisture and air mixture to drain from the tank.
Keep the compressor tilted until all moisture has been removed.
Once the moisture has been completely drained, close the drain valve.
Drain moisture from tank into a suitable container.
NOTE: Condensate is a polluting material and should be disposed of in compliance with local regulations.
If drain valve is clogged, release all air pressure by pulling the safety valve. Remove and clean valve, then reinstall.
WARNING:
Do not attempt to tamper with safety valve. Anything loosened from this device could fly up and hit you. Failure to heed this warning could result in death or serious personal injury.
SAFETY
VALVE
Fig. 4
Turn off drain valve until completely closed.
CHECKING THE SAFETY VALVE
See Figure 4.
WARNING:
If air leaks after the ring has been released, or if the valve is stuck and cannot be actuated by the ring, Do Not use the air compressor until the safety valve has been replaced. Use of the air compressor in this condition could result in serious personal injury.
The safety valve will automatically release air if the air receiver pressure exceeds the preset maximum. The valve should be checked before each day of use by pulling the ring by hand.
Turn the air compressor on and allow the tank to fill. The compressor will shut off when the pressure reaches the preset maximum.
Turn the air compressor off.
Pull the ring on the safety valve to release air for twenty seconds.
Release the ring. Air must immediately stop escaping when the ring is released. Any continued loss of air after releasing the safety valve ring indicates a problem with the safety valve. Discontinue use and seek service before continued use of the air compressor.

OPERATION
WARNING:
Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury.
WARNING:
Always wear safety goggles or safety glasses with side shields when operating power tools. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury.
CAUTION:
Do not use in an environment that is dusty or otherwise contaminated. Using the air compressor in this type of environment may cause damage to the unit.
APPLICATIONS
Air compressors are utilized in a variety of air system applications. Match hoses, connectors, air tools, and accessories to the capabilities of the air compressor.
You may use this tool for purposes listed below:
Operating some air-powered tools.
Inflating tires, air beds, sports equipment, etc.
PRE-STARTING CHECKLIST
WARNING!
Failure to perform the PRE-STARTING CHECKLIST may result in mechanical failure, property damage, serious injury or even death.
The following steps should be performed prior to operating the unit. If any condition of the checklist is not satisfied, make the necessary adjustments or corrections before starting the compressor.
WARNING!
Neverassumeacompressorissafetoworkonjustbecause it is not operating. It could restart at any time. Follow all safety precautions outlined in MAINTENANCE.
The compressor is shipped with lubricant in the crankcase. Check lubricant level per specifications (using the instruction found in Lubrication). Make sure all safety valves are correctly installed. (using the instruction found in Features).
Be sure all guards are in place and securely mounted (using the instruction found in Features).
Drain moisture from the air tank(s). Never attempt to drain the tank(s) without first relieving the system
pressure (using the instruction found in Draining the Tank).
STARTING & STOPPING THE COMPRESSOR
Connect the air line to the quick coupler.
Rotate regulator knob fully counterclockwise in order to close the air flow.
Ensure both drain valves are closed.
Fill the engine with oil through oil fill hole.
Fill the compressor pump with oil. Do not overfill.
Fill the fuel tank with fuel.
Open the petcock on the unloader valve for cold starts (turn clockwise or in).
Flip the toggle on the pilot valve to the “MANUAL UNLOAD” position (see Pilot Valve Adjustments).
Start the gas engine (refer to gas engine owner’s manual for more detailed start-up procedures):
–Adjust choke and open fuel valve.
–Pull the cord.
–Move choke to run.
Watch and listen for excessive vibration and unusual noises. If either exist, stop the compressor and refer to
Troubleshooting.
Allow the compressor to run for a few minutes. Close the petcock (turn counterclockwise or out).
Flip the toggle on the pilot valve to the “RUN” position. The compressor should pump up the tank to 135
PSI, then unload. If pressure exceeds 135 PSI, see
Troubleshooting.
New compressors should be run with approximately 80 PSI of air pressure in the tank for 1 hour to break-in (use regulator to control tank pressure). This will allow the compressor time to warm up and seat the rings.
To stop the compressor, shut the engine off.
USING THE AIR COMPRESSOR
See Figure 5.
WARNING:
Always ensure the regulator pressure gauge read zero before changing air tools or disconnecting the hose from the air outlet. Failure to do so could result in possible serious personal injury.
Rotate pressure regulator knob to desired line pressure. Turning the knob clockwise increases air pressure at the outlet; turning counterclockwise reduces air pressure at the outlet.

OPERATION
WARNING:
Your tool may require more air consumption than this air compressor is capable of providing. Check the tool manual to avoid damage to the tool or risk of personal injury.
Following all safety precautions in this manual and the manufacturer’s instructions in the air tool manual, you may now proceed to use your air-powered tool.
If using an inflation accessory, control the amount of air flow with the pressure regulator knob. Turning the knob fully counterclockwise will completely stop the flow of air.
NOTE: Always use the minimum amount of pressure necessary for your application. Using a higher pressure than needed will drain air from the tank more rapidly and cause the unit to cycle on more frequently.
When finished, always drain the tank and stop the compressor. Never leave the unit in running unattended.
END OF OPERATION/STORAGE
Shut off the engine.
Disconnect the spark plug wire from the spark plug and wrap around handle area to prevent damage when not in use.
Wearing safety glasses drain tank of air by pulling the ring on the safety valve. Use other hand to deflect fast moving air from being directed toward your face.
Drain tank of condensation by opening both drain valves on bottom of tank. Tank pressure should be below 10 psi when draining tank.
Air hose should be disconnected from compressor and hung open ends down to allow any moisture to drain.
Compressor and hose should be stored in a cool, dry place.
