Break-In Procedures
ACAUTION
Serious damage may result if the following
break-in instructions are not closely followed.
This procedure is required only once; before the air
compressor is put into service. Some form of piping or
shut-off valve must be installed before beginning the
break-in procedure. A 1/2" NPT shut-off globe valve
should be installed at the air compressor tank. Do not
use a ball valve.

Recheck compressor wiring. Make sure wires are
secure at all terminal connections. Free all contacts
of loose wire cuttings, etc.
Check oil level in the crankcase before operation.
The oil level should be even with the top of the fill
hole and must not be allowed to be lower than 3/8"
(six threads down) from the top at any time. Add oil
if level is low.
3. O pen the sh ut-off valve fu I ly, to perm it air to escape
and to prevent pressure build-up in the air tank.
4. Turn ON the air compressor.
5. Run the air compressor for 30 minutes to seal the
rings and lubricate all internal surfaces.
6. Check all air line fittings and connections/piping for
air leaks by applying a soap solution. Correct as
necessary. Even minor leaks can cause this air
compressor to overwork, resulting in premature
break-down or inadequate performance.
7. Check for excessive vibration and noise. Adjust air
compressor belt guard as necessary to eliminate
chatter. Re-adjust or shim the air compressor feet,
if necessary for proper level.
8. Close the shut-off valve and let the air compressor
pump up to cut-out pressure. Tum the air compres­
sor off and check oil level. Add oil if necessary.
Connect the air hose to the air outlet adapter.
Your compressor is now ready for use.
OPERATING PROCEDURES
1. Before attaching an air hose or accessory, make
sure the pressure switch OFF/AUTO lever is in the
"OFF" position.
2. Attach hose and accessory.
AWARNING
ACAUTION
Compressed air from ttie outfit may contain water
condensation and oil mist 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.
TOO MUCH AIR PRESSURE CAUSES A HAZ­
ARDOUS
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.
3. Turn the compressor on and allow tank pressure to
build. The motor will stop when tank pressure
reaches cut-out pressure.
Your outfit is ready for use.
MAINTENANCE
AWARNING
UNIT CYCLES AUTOMATICALLY WHEN POWER IS ON. WHEN DOING MAINTENANCE, YOU MAY
BE
EXPOSED TO VOLTAGE SOURCES, COMPRESSED AIR OR MOVING PARTS. PERSONAL
INJURIES CAN OCCUR. BEFORE PERF6RMING MAINTENANCE OR REPAIR, TURN OFF AND
LOCK OUT ELECTRIC POWER AND BLEED OFF AIR TANK PRESSURE. NEVER OPERATE THE
COMPRESSOR WITH THE BELT GUARD REMOVED.
Air Compressor
A clean air compressor runs cooler and provides longer
service. Clean or blow off fins and any other parts of the
air compressor that collect dust or dirt. Do not place
rags, containers or other material on or against the
ventilation openings in the belt guard. Adequate ventila­
tion is necessary to maintain proper air compressor
operating temperature.
Air Filter - Inspection and
Replacement
NOTE
Keep the air filter clean at all times. Do not operate the
compressor with the air filter removed.
