Air Compressors
Installation (continued)
Do not lift or move
unit without appro-
priately rated equipment. Be sure the
unit is securely attached to lifting device
used. Do not lift unit by holding onto
tubes or interstage coolers. Do not use
unit to lift other attached equipment.
Never use the wood shipping skids for
mounting the compressor.
The compressor should be installed on
a level floor or foundation of sufficient
strength and rigidity to support it with-
out vibrating. It is recommended to use
shims under the mounting feet to level
the compressor, to prevent rocking and
excessive vibration. To reduce vibration,
isolator pads, Model 4C975, are recom-
mended. When isolators are used, install
a flexible coupling between the tank
and any pipe permanently attached to
the tank.
When permanently
installing compres-
sor for stationary use or mobile use such
as a truck, avoid overstressing a mount-
ing foot by "pulling the foot down in. to
the floor. This may cause eventual failure.
Install and operate unit at least 24 in. from
any obstructions in a clean, well ventilated
area. This will ensure an unobstructed
flow of air to cool compressor and allow
adequate space for maintenance. Never
operate compressor in a small, closed
room. Vent the engine exhaust to outside.
Do not locate the
compressor air inlet
near steam, paint spray, sandblast areas
or any other source of contamination.
Assembly
TANK
(OUTLET VALVE SOLD SEPARATELY ON
ALL MODELS)

nipple. Install assembled valve in either
end of the tank.

STARTER SOLENOID (UNIT WITH
ELECTRIC START ONLY)
1. Disconnect negative cable from
battery terminal before attaching
wires to the solenoid.
2. Remove the 1/4 in. nut from the left
stud. Do not make contact with the right
stud to avoid possible engine ignition.
3. Attach the positive (red) battery cable
to the left stud and reinstall the 1/4 in.
nut. Tighten the nut one full turn
after it is finger tight (See Figure 2).

4. Attach the negative (black) battery
cable to a convenient ground. The
best place is at the engine mount-
ing bolt. Other secure places on the
engine are suitable.
5. Reattach the negative cable to the
battery.

ENGINE LUBRICATION

This unit is shipped without oil. Before
operating, oil must be added. See
the engine manual for recommended
engine lubrication

PUMP LUBRICATION

operating compressor, fill pump crank-
case with compressor oil as instructed.
Some residual oil may still be in the
pump leaving a thin coat on the sight
glass, however; there is not enough oil
to operate the unit. Synthetic oil has
proven to provide superior lubrication
and is recommended for Speedaire air
compressors. Use 10W30 100% synthetic
oil such as Mobil 1 (Stock No. 4F743).
Single viscosity, ISO100 (SAE 30) non-
detergent compressor oil such as Mobil
Rarus ® (Stock No. 4ZF21), can also be
used. Both are available at your local
Grainger branch. See Replacement
Parts List for oil quantity. Add oil only
through the oil fill plug (See Figure 3).
Fill to the center of the sight gauge.
Pouring oil into any other orifice will
cause oil to leak and spray out
during operation.
NOTE: Use of petroleum based automo-
tive engine oil will cause carbon

deposits to build up on the valves. This
will shorten the life expectancy and will
require more frequent service to the
valves. Do not use ATF hydraulic fluid,
two-cycle oil or any oil treatment prod-
uct. Do not use diester synthetic oil.
