Oil Injector 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 Texaco Rando® HD22 or SAE 10W non-detergent 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.

c.

 Retighten bleeder screw.

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.

Transmission Lubrication

The transmission in this machine requires SAE 80/90 gear oil. Remove the dipstick to check that there is oil on 

the end of it. If not, fill as required – do not overfill.

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.

Danger, Warning, Caution, and Instructional Decals

Always make the cleaning of these important decals a part of your regular maintenance routine. If they are dam-

aged or illegible, replace them immediately. Your safety, and the safety of others is involved!
