Break-In
Procedures
Sedous 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.
1.
2.
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.
Open the shut-offvalve
fully, to permit air toescape
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. Turn 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.

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.
