Become familiar with these terms before operating the unit.
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 Standards for Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your accessory. When the tank pressure drops to a certain low level the motor will restart automatically. The low pressure at which the motor automatically restarts is called "cut-in" pressure.
Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off - protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called "cut-out" pressure.
Branch Circuit: Circuit carrying electricity from electrical panel to outlet.
To Lock Out Power: Place a lock on the line power switch so no one else can turn on the power.
DUTY CYCLE

Washer (supplied) 3/8" Lag Screw (not supplied) Shim Under Washer (not supplied) Surface Line Concrete Anchor (not supplied)⚠ WARNING: Risk of electrical shock. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician
A qualified electrician needs to knows the following before wiring:
- The amperage rating of the electrical box should be adequate. Refer to the Specification Chart, in the parts manual, for this information.
- The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of motor, for this information.
NOTE: The wiring must be the same as the motor nameplate voltage plus or minus 10%. Refer to local codes for recommended wire sizes, correct wire size, and maximum wire run; undersize wire causes high amp draw and overheating to the motor.
⚠ WARNING: Risk of electrical shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders.
GROUNDING INSTRUCTIONS
This product should be connected to a metallic, permanent wiring system, of an equipment-grounding terminal or lead on the product.
VOLTAGE AND CIRCUIT PROTECTION
Refer to the specification chart for the voltage and minimum branch circuit requirements.
⚠️CAUTION: Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.
- Voltage supply to circuit must comply with the National Electrical Code.
- Circuit is not used to supply any other electrical needs.
- Extension cords comply with specifications.
- Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse. NOTE: If compressor is connected to a circuit protected by fuses, use only time delay fuses. Time delay fuses should be marked "D" in Canada and "T" in the US.
If any of the above conditions cannot be met, or if operation of the compressor repeatedly causes interruption of the power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to change the cord set.
AIR DISTRIBUTION SYSTEM
⚠ WARNING: 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 lines.
The next figure represents a typical air distribution system. The following are tips to remember when setting up the air compressor's air distribution system.
- 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' (30.5 m) long, use the next larger size. - Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.
- A flexible coupling is recommended to be installed between the air discharge outlet and main air distribution line to allow for vibration.
- A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually to high for individual air driven tools.

Tank Pressure Gauge Pressure Switch Auto(I)/Off(O) Switch Safety ValveDESCRIPTION OF OPERATION
Become familiar with these controls before operating the unit.
Auto(I)/Off(0) Switch: Turn this switch "Auto (I)" to provide automatic power to the pressure switch and "Off (O)" to remove power at the end of each use.
Pressure Switch: The pressure switch automatically starts the motor when the air tank pressure drops below the factory set "cut-in" pressure. It stops the motor when the air tank pressure reaches the factory set "cut-out" pressure.
Safety Valve: If the pressure switch does not shut off the air compressor at 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 pressure switch "cut-out" setting).
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.
Globe Valve: (sold separately, not shown) Opens and closes air discharge valve. Turn knob counter-clockwise to open and clockwise to close.
Regulator (sold separately, not shown): An air pressure regulator or a separate air transformer which combines the functions of air regulation and/or moisture and dirt removal is recommended for most applications.
Cooling System (not shown): This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled.
Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.
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.

text_image
Drain ValveCheck 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.

text_image
Check Valve Reset Button Pressure Release ValvePressure Release Valve: The pressure release valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches "cut-out" pressure or is shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds. No air should be heard leaking when the motor is running or after the unit reaches "cut-out" pressure.
Motor Overload Protector: This motor has a manual thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart:
- Place the Auto/Off lever in the "Off" position.
- Allow the motor to cool.
- Depress the red reset button on the motor.
- Place the Auto/Off lever in the "Auto" position to restart the motor.

NOTE: Once the motor pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" (1.6 mm) to prevent excessive belt wear.
The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16" (1.6 mm) to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps:
-
Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.
-
Remove belt guard.
-
Place a straightedge against the outside of the flywheel and the motor drive pulley.
-
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" (1.6 mm).

BELT MOTOR PULLEY FLYWHEEL A1 A2 B1 B2 A1= A2 (MEASURED) B1= B2 (VISUAL) STRAIGHT EDGE- If the difference is greater than 1/16" (1.6 mm) loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley's position on the shaft until the A1 and A2 measurements are within 1/16" (1.6 mm) of each other.
- Tighten the motor drive pulley set screw.
- Visually inspect the motor 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 motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2.
- Retighten the motor drive pulley setscrew. Torque to 70-100 in-lbs (7.9-11.3 Nm).
- Reinstall belt guard.
AIR COMPRESSOR PUMP INTAKE AND ExHAUST VALVES
Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves.
INSPECT AIR LINES AND FITTINGS FOR LEAKS
- Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.
- Apply a soap solution to all air line fittings and connections/piping.
- Correct any leaks found.
IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance.
AIR COMPRESSOR HEAD BOLTS - TORQUING
The air compressor pump head bolts should be kept properly torqued. Check the torques of the head bolts after the first five hours of operation. Torque to 28–39 ft.-lbs (38.0-52.9 Nm).
