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 founda-
tion 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 pres-
sure rating, plastic pipe can burst from air pres-
sure. Use onlymetal pipe for air distribution lines.
If a pipe line isnecessary, 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 isover 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
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
IMPROPER GROUNDING CAN RESULT IN ELEC-
TRICAL SHOCK. WIRING OF THE PRESSURE
SWITCH, ELECTRIC MOTOR AND MANUAL ON/
OFF SWITCH SHOULD BE DONE BYA LICENSED
ELECTRICIAN IN ACCORDANCE WITH NA-
TIONAL AN D LOCAL CODES AND ORDINANCES.
To prevent added current draw and motor overheating
we recommend the use of 12 gauge (AWG) wire, not
exceeding a 70 foot length. The wire must be rated at a
minimum temperature of 75° C.
When connecting wires, make sure that: (1)the electrical
box is large enough; (2)service is ofadequate amperage
rating; (3)the supply line has the same electrical charac-
teristics (voltage, cycles and phase) as the motor;, (4)the
line wire isthe 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 elec-
trical apparatus and wiring. These should be consulted
and observed. Our recommended wire sizes may be
smaner than the minimum set up by local ordinances. If
so, the larger size wire should be used to prevent
excessive line voltage drop. Forwiring instructions, see
the diagram inside the pressure switch cover.

tempt to operate this air comprassor 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-

Electrical wiring must be located away from hot
surfaces such as the compressor head, compres-
sor cylinder or compressor outlet tube.
