EXCESSIVE VIBRATION MAY WEAKEN THE
AIR TANK AND CAUSE AN EXPLOSION.
THE OUTFIT MUST BE MOUNTED AS
DESCRIBED AND ILLUSTRATED BELOW.
1. The air compressor must be bolted to the floor.
Bolting holes are provided in the base feet.
2. Mount the air compressor on a solid level foundation
with no strain to the air tank feet. Solid shims may
be used if necessary.

Piping

Plastic or PVC pipe is not designed for use
with compressed air. Regardless of its
indicated pressure rating, plastic pipe can
burst from air pressure. Use only metal pipe
for air distribution lines.
If a pipe line is necessary, use pipe that is the same size
as the air tank valve. Piping that is too small will restrict
the flow of air. If piping is over 100 feet long, use the next
larger size. Bury underground lines below the frost line
and avoid pockets where condensation can gather and
freeze. Apply pressure before underground lines are
covered to make sure all pipe joints are free of leaks.

Lubrication and Oil

Compressors are shipped without oil. Do not attempt to
operate this air compressor without first adding oil to the
crankcase.
Place unit on a level surface. Remove oil fill plug and
slowly add a special compressor oil such as Sears 9-
16426 or SAE-20-20W SF motor oil until it is even with the
D20410

top of the oil fill hole. (It must not be allowed to be lower
than 3/8" - 6 threads down - from the top.) When filling the
crankcase, the oil flows very slowly. If the oil is added too
quickly, it will overflow and appear to be full. (Crankcase
oil capacity is 16 fluid ounces.) Under winter-type condi-
tions use SAE 10W oil. (Multi-viscosity oil - 10W30 - will
leave carbon deposits on critical components reducing
performance and compressor life.) Replace oil fill plug.

Wiring Instructions

To prevent added current draw and motor overheating we
recommend the use of 12 gauge (AWG) wire, not exceed-
ing a 70 foot length. The wire must be rated at a minimum
temperature of 75
When connecting wires, make sure that: (1) the electrical
box is large enough; (2) service is of adequate amperage
rating; (3) the supply line has the same electrical charac-
teristics (voltage, cycles and phase) as the motor; (4) the
line wire is the proper size and (5) no other equipment is
operated from the same line. Various national and local
codes and standards have been set up covering electri-
cal apparatus and wiring. These should be consulted and
observed. Our recommended wire sizes may be smaller
than the minimum set up by local ordinances. If so, the
larger size wire should be used to prevent excessive line
voltage drop. For wiring instructions, see the diagram
inside the pressure switch cover.
Electrical wiring must be located away from hot surfaces
such as the compressor head, compressor cylinder or
compressor outlet tube.

BE DONE BY A LICENSED ELECTRICIAN
IN ACCORDANCE WITH NATIONAL AND
LOCAL CODES AND ORDINANCES.
