Break-In Procedure; Operating Procedures - Craftsman 919.727350 Owner's Manual

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-
connector grounding plug, and a three-slot
receptacle that will accept the plug.
• no longer than 50 feet
• in good condition
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-

EACH TIME THE COMPRESSOR IS
USED.
Compressed air from the outfit may contain
water condensation. Do not spray unfil-
tered 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.

Break-in Procedure

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