2.Circuit is not used to supply any other electrical needs (lights, appliances, etc.)

3.Extension cords comply with a 15 amp circuit breaker or 15 amp time delay fuse.

4.Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse.

If any of the above conditions cannot be met, or if opera- tion of the compressor repeatedly causes interruption of power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to change the cord set.

Extension Cords

It is preferable to use extra air hose instead of an exten- sion cord to avoid voltage drop and power loss to the motor, and to prevent overheating.

If an extension cord must be used, be sure it is:

12 gauge (AWG) or heavier. (Wire size increases as gauge number decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR 16 AWG.)

a three-wire extension cord that has a three-connec tor grounding plug, and a three-slot receptacle that will accept the plug.

no longer than 50 feet

in good condition

Break-in Procedure

Serious damage may result if the following break-in instructions are not closely fol- lowed.

This procedure is required only once, before the air com- pressor is put into service.

1.Set the pressure switch "AUTO/O" lever in the "O" position for "Off".

2.Plug the power cord into the correct branch circuit receptacle.

3.Do not attach hose to outlet. Leave the outlet open to the atmosphere.

4.Turn the regulator clockwise, opening it fully, to prevent air pressure build-up in the tank.

5.Move the "AUTO/O" lever to "AUTO". The com- pressor will start.

6.RUN THE COMPRESSOR FOR 15 MINUTES. Make sure the regulator is open and there is no tank pressure build-up.

7.After 15 minutes, close the regulator by turning it counterclockwise. The air tank will fill to cut-out pressure and then the motor will stop.

OPERATING PROCEDURES

1.Before attaching air hose or accessories, make sure the "AUTO/O" lever is set to “O” and the air regulator is closed.

2.Attach hose and accessories.

TOO MUCH AIR PRESSURE CREATES A HAZARDOUS RISK OF BURSTING. CARE-FULLY FOLLOW STEPS 3 AND 5 BELOW EACH TIME THE COMPRESSOR IS USED.

Compressed air from the outfit may contain water condensation. Do not spray unfiltered air at an item that could be damaged. Some air operated tools or devices may require filtered air. Read the instructions for the air tool or device.

3.Check the manufacturer’s maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating.

4.Turn the "AUTO/O" lever to “AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure.

5.Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. Your compressor is ready for use.

6.Always operate the air compressor in well- ventilated areas; free of gasoline or other solvent vapors. Do not operate the compressor near the spray area.

WHEN YOU ARE FINISHED:

7.Set the “AUTO/O” lever to “O”.

8.Turn the regulator counterclockwise and set the outlet pressure to zero.

9.Remove the air tool or accessory.

10.Open the regulator and allow the air to slowly bleed from the tank. Close the regulator when tank pressure is approximately 20 psi.

11.Drain water from air 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.

NOTE:

If drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.

12.After the water has been drained, close the drain valve. The air compressor can now be stored.
