Ranger Products R23, Installation And Operation Manual

23

Add oil to the lubricator if the fluid level is below the    

middle of the sight glass. Remove the reservoir by turning 
counter-clockwise and pulling down. Add SAE 10W non-
detergent oil or an air tool oil if necessary.  (See Fig. 1)

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 
pressure limiter is essential to safe operation of the 
machine. (See Fig. 2)

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. 3)

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 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.

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.
