OPERATING INSTRUCTIONS

BEAD LOOSENING AND DEMOUNTING

Remember to remove all weights from both sides of 

the wheel. Weights left on the back side of the wheel may 

cause the wheel to be clamped un-level. This may result in 

the combination mount/demount head contacting the rim

causing scratches. On alloy wheels, always rotate the 

wheel one turn after setting the head to insure proper wheel 

chucking.

u

 Always review nicks and scratches with owners of  

expensive wheel and tire combinations prior to servicing.

u

  Review the performance wheel section of this manual 

prior to servicing performance tire/wheel combinations.

1. Deflate tire completely by removing the valve core from 

the valve stem. (See Fig. 11.1).

2. The clamps on the table top may extend beyond the 

table top itself. To avoid damaging the clamps and/or 

wheel, move the clamps to their full inward position before         

positioning a tire for bead loosening.

3. Always loosen the bead on the narrow side of the wheels 

drop center first. (See Page 19 for better description of the 

drop center.)

4. Use extra care in positioning the bead breaker shoe on 

larger wheels/tires, and on alloy wheels. Make sure the 

shoe rests next to but not on the rim, and not on the tire 

sidewall.

5. Pull the bead breaker shoe away from the machine and 

roll the wheel into position. The valve stem should be in the 

2 o’clock position.

6. Position the bead breaker shoe against the tire next to, 

but not on, the rim. Press the breaker pedal to actuate the 

shoe and loosen the bead. It may be necessary to loosen 

the bead in multiple locations around the tire.

(See Fig. 11.2)

7. Turn wheel around and repeat procedure on the other 

side of the wheel. This should be the long side of the drop 

center. It will be easier to clamp the wheel to the table top if 

the lower bead is loosened last. (See Fig. 11.3)

8. Determine the mounting side of the wheel. The 

mounting side is the narrow side of the drop center. The tire 

is removed for clarity. (See Fig. 11.4)

The unit must be properly operated and 

maintained to help avoid accidents that could 

damage the unit and injure the operator or 

bystanders. This section of the Operating 

Instructions manual review basic operations 

and use of controls. These instructions should 

be reviewed with all employees before they are 

allowed to work with the machine. 

Keep these instructions near the machine for 

easy reference.

CAUTION! 

This machine may operate differently from 

machines you have previously operated. 

Practice with a regular steel wheel and tire  

combination to familiarize yourself with the 

machine’s operation and function.
