Important: Always read and follow the operating instructions. • 21
3. Depress inflation pedal to position 1 to start air-
flow through the hose and into the tank. Maintain a
steady pressure for constant flow.
4. Watch the rising pressure on the tank gauge and
the gauge on the machine. Machine gauge should
cycle between check and inflation pressures while
tank gauge climbs steadily. As tank pressure reaches
60 PSI, the pressure limiter should stop the airflow
automatically. Both gauges should read 60 PSI ± 5 PSI.
5. Release inflation pedal. Check manual release
valve function by pressing the button and releasing
pressure from the tank until it reaches 50 PSI.
Disconnect inflation hose, and release air inside tank.
6. Replace pressure limiter if it fails to cycle properly
during inflation, if it fails to shut air supply off at 60 PSI,
or if it malfunctions in any other way. Do not operate
machine with a faulty pressure limiter.
Installation Instructions
Proper unit installation is necessary for safe
use and efficient operation. Proper installa-
tion also helps protect the unit from dam-
age and makes service easier. Always place
safety poster and instructions near the unit.
Location
Select a location using the drawings below. The area
should provide the operator with enough space to use
the equipment in a safe manner. The area selected
should be well lit, easy to clean and should be away
from oil, grease, brake lathe chips, etc. Avoid areas
where bystanders and customers may be present.
Air Source
The air/electric models require a 5 CFM air source at
150 PSI. The operating pressure range for all models is
between 125 PSI and 175 PSI at the machine.
The unit is furnished with a 1/4" pipe thread male fit-
ting for easy connection. This connection is located on
the right side of the rear of the machine. A 1/4" ID hose
(or pipe) for connection to the machine is satisfactory.
Sufficient air pressure assures good performance.
Electrical Source
Electric models require power from a 30 amp, 120
volt electrical circuit with a 125V, 30A, twist-lock recep-
tacle. Refer to the serial tag located on the lower part
of the machine for specific electrical requirements for
the unit. Have a licensed electrical technician perform
any necessary changes to the power source before
plugging in the unit. The electrical source must have a
solid connection (less than 1 ohm) between ground
and building ground.
