OIL DRAIN ExTENSION
Some models include an oil drain
extension and cap (found with the
owner's manual). Install the oil drain
extension and cap before adding oil to
the pump. To avoid oil leaks, it is highly
recommended to apply PTFE thread
sealant tape or paste type sealant to
the threads on each end of the oil drain
extension. Screw the cap onto one
end of the extension. Remove the oil
drain plug from the base of the pump
and install the oil drain extension (See
Figure 6).

LubRICATION
ThIS UNIT CONTAINS
NO OIL! Follow
lubrication instructions before
operating compressor.
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.
automotive oil which has shown to
increase carbon deposits on the valves,
resulting in more frequent service and
reduced life.

WIRING
Fill Line
Local electrical wiring codes differ from
area to area. Source wiring, plug and
protector must be rated for at least the
amperage and voltage indicated on your
motor nameplate, and meet all electrical
codes for this minimum. Use a slow blow
fuse type T or a circuit breaker.
Overheating, short-circuiting
and fire damage will result
from inadequate wiring.
NOTE: 120 volt, 15 amp units can be
operated on a 120 volt 15 amp circuit
under the following conditions:
1. No other electrical appliances or lights
are connected to the same branch
circuit.
2. Voltage supply is normal.
3. Circuit is equipped with a 15 amp
circuit breaker or a 15 amp slow blow
fuse type T (For Canada use Type D).
If the above conditions cannot be met
or if nuisance tripping of the current
protection device occurs, it may be
necessary to operate the compressor
from a 120 volt 20 amp circuit. Some
models convert to 240 volt operation,
see DUAL VOLTAGE MOTOR.

2. If repair or replacement of the cord or
plug is necessary, do not connect the
grounding wire to either flat blade
terminal. The wire with insu
lation having an outer surface that is
green with or without yellow stripes is
the grounding wire.
