Reconnect the air when service/adjustments are complete.
Inflation Pedal Pressure Limiter Maintenance
The inflation pedal pressure limiter helps prevent inflation of
standard size or larger tires or tubes beyond 60 PSI to
minimize risk of explosion. This device is for the safety of
the operator and bystanders. Proper operation of the pres-
sure limiter is essential to safe operation of the machine.
(See Fig. 1)
Check operation of the pressure limiter as follows at least
once a month:
1. Remove tires and/or wheels from the machine.
2. Connect the inflation hose to an empty service tank with
a pressure gauge (gauge should read 0). Use a certified
tank with at least 250 PSI pressure rating. (See Fig. 2)
3. Depress inflation pedal to position one 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 air flow automatically. Both
gauges should read 60 PSI ± 5 PSI.
5. If the pressure exceeds 60 PSI, adjust the knob on the
regulator by lifting the locking cover and turning
COUNTERCLOCKWISE. After adjustment is made, secure
cover in the locked position.
6. Repeat steps 1-6. Re-adjust if necessary.
7. After pressure limit has been set, check the 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. (See Fig. 4)
INSTALLATION INSTRUCTIONS
Location
Select a location using the drawings on page 23. 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.
THE PRESSURE LIMITER IS PRE-SET AT THE
FACTORY AND SHOULD NEED NO ADJUSTMENT.
ADJUST ONLY IF PRESSURE EXCEEDS 60 PSI.
Operating a tire changer with a defective,
improperly adjusted, or by-passed pressure limiter
could result in a tire explosion with severe injury or
death to the operator or bystanders. Always be
sure that the pressure limiter is operating properly
on the machine at all times. Pressure limiter is set
at 60 PSI. Any required inflation above 60 PSI
should be performed in an inflation chamber/safety
cage. A tire explosion may cause personal injury or
death to operator or bystanders.

Proper unit installation is necessary for safe use
and efficient operation. Proper installation also
helps protect the unit from damage and makes
service easier. Always keep this manual unit.
