To Add Oil To Pump
Compressors are
shipped without oil. A small amount of oil may be present in the pump upon receipt of the air compressor. This is due to plant testing and does not mean the pump contains oil. Do not attempt to operate this air compressor without first adding oil to the crankcase. Serious damage can result from even limited operation unless filled with oil and broken in correctly. Make sure to closely follow initial start-up procedures.
11- ENG
D23766
NOTE: Do not allow oil to be lower than 3/8" (6 threads) from the top at any time. When filling the crankcase, the oil flows very slowly into the pump. If the oil is added too quickly, it will overflow and appear to be full. Slowly fill crankcase to the top of the fill hole. NOTE: Crankcase oil capacity is approximately 16 fluid ounces (473.2 ml).
3. Replace oil fill plug (A).
Multi-Viscosity
motor oils, like 10W 30, should not be used in an air compressor. They leave carbon deposits on critical components, thus reducing performance and compressor life. Use air compressor oil only.
NOTE: Oil is included with some
units. If oil is not included, use an oil specifically formulated for use in an air compressor, such as Porter-Cable PAS1 air compressor oil. Oil may be found at the store where the air compressor was purchased.
1. Place unit on a level surface.

Voltage and Circuit Protection
Refer to the Parts Manual for the voltage and minimum branch circuit requirements.
Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.
1. Voltage supply through branch circuit is 15 amps.
2. Circuit is not used to supply any other electrical needs (lights, appliances, etc.).
3. Extension cords comply with specifications.
4. 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 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
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.
120/240 Dual Voltage Motor
This model has a dual voltage motor, 120 and 240 volt. It is wired for 120 volt but can be converted to 240 volt operation. Instructions for connecting the motor for operation at 240 volt can be found printed on the label attached to the side of the motor.
When converting to
240V operation, the attached three-prong 120V cord assembly must be replaced with a three-pronged 240V cord assembly (K-0080) that can be purchased through a Sears Service Center.

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 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.

Description of Operation
Become familiar with these controls before operating the unit. On/Auto/Off Switch: Turn this switch ON to provide automatic power to the pressure switch and OFF 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). Outlet Pressure Gauge: The outlet pressure gauge indicates the air pressure available at the outlet side

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. 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.
Pressure 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 continuous leaking after unit reaches "cut-out" pressure.

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. Set the On/Auto/Off lever to "Off".
3. Turn the regulator counterclockwise and set the outlet pressure to zero.
4. Remove the air tool or accessory.
5. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring.
6. 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.
7. 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.
8. Protect the electrical cord and air
hose from damage (such as being stepped on or run over). Wind them loosely around the compressor handle. (If so equipped)
Store the air compressor in a clean and dry location.
