Voltage And Circuit Protection; Extension Cords; Break-In Procedure - Craftsman 919.727340 Owner's Manual

Voltage and Circuit Protection

Refer to page 5 (Specification Chart) for the voltage and
circuit protection requirements of your compressor. Use only
a fuse or circuit breaker that is the same rating as the branch
circuit the air compressor is operated on. If the compressor
is connected to a circuit protected by fuses, use only dual
element time delay fuses.

Extension Cords

It is preferable to use extra air hose instead of an extension
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-connector
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 followed.
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.
