Oil Maintenance
The oil injector (on units so equipped) typically require annual service. The oil level in the oil reservoir tank should
be checked regularly.
1. Add oil to the oil reservoir tank if the fluid level in the tank is at the “add” mark. Remove cap from the oil
reservoir tank and add Chevron Regal® R & O 32 oil to the “full” mark. Replace the cap and clean up any spilled oil.
Important: If the hose between the reservoir and injector is ever empty of oil, an air lock will form. After filling
the reservoir tank, the line must be bled of air at the injector connection as follows:
a. Remove the side panel and locate the oil injector.
b. Loosen the bleeder screw until oil drips from the screw (or press bleeder button, if so equipped).
c. Retighten bleeder screw (if required).
d. Cycle the clamp valve a few times checking for oil and air leaks.
e. Test the machine for full function before returning the machine to operation.
Air Gauge Check and Recalibration
1. Inflate a standard 15” passenger car tire/wheel assembly to 32 PSI. Use a high quality stick-type pressure
gauge to verify the pressure. Attach the tire changer’s inflation hose to the valve stem and check the pressure
reading on the air gauge. If it does not read 32 PSI, recalibrate the gauge.
2. Remove the screw-on lens. Loosen the 2 screws on the face of the gauge. Loosen them just enough so that
the gauge face moves. Do not remove the screws.
3. Rotate the gauge face until the 32 PSI mark is aligned with the gauge needle. Tighten the 2 screws and
replace the lens.
