Before Starting

WARNING: Do not operate this unit until you read this
instruction manual for safety, operation and maintenance
instructions.

Break-in Procedure

NOTICE: Risk of property damage. Serious damage may result if
the following break-in instructions are not closely followed.
This procedure is required before the air compressor is put into
service and when the check valve or a complete compressor pump
has been replaced.
1. Make sure the Auto/Off switch is in the "Off (O)" position.
2. Plug the power cord into the correct branch circuit receptacle.
(Refer to Voltage and Circuit Protection paragraph in the
installation section of this manual.)
3. Open the drain valve fully to permit air to escape and prevent
air pressure build up in the air tank during the break-in period.
4. Move the Auto/Off switch to "Auto (-)" position. The
compressor will start.
5. Check all air line fittings and connections/piping for air leaks
by applying a soap solution. Correct if necessary.
NOTE: Minor leaks can cause the air compressor to overwork,
resulting in premature breakdown or inadequate performance.
6. Run the compressor for 15 minutes.
7. Check for excessive vibration.
8. Turn the Auto/Off switch to the "Off (O)" position.
9. Close the drain valve.
10. Turn the Auto/Off switch to the "Auto (-)" position. The air
receiver will fill to "cut-out" pressure and the motor will stop.

the air outlet is equipped with a quick connect socket.
WARNING: Risk of bursting. Too much air pressure causes a
hazardous risk of bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The regulator outlet
pressure must never exceed the maximum pressure rating.
