H. 

The tool clearance may change with machine use and 

should  be  inspected  often.  Failure  to  maintain  the  proper 
clearance may result in damage to the wheel rim and/or tire. 
 

 

J. 

Normal table top rotation for demounting is clockwise. 

Depress the table top pedal to rotate this direction. To rotate 
the table top counterclockwise, lift the pedal up with your toe.

 

 

K. 

Table top rotation can be stopped at any time by re-

moving your foot from the rotation pedal.

 

 

At times during the  mounting and demounting pro-

cedure, the bead lifting tool may encounter resistance and 
can be thrown. Keep one hand firmly on the tool to avoid 
possible tool disconnect. Use the reversing feature to back 
out of jam-ups. A thrown tool can cause injury.

 

10. Insert the smooth curved end of the bead lifting tool over 
the forward end of the demount head and below the top bead of 
the tire. Lift the bead up and over the knob on the Mounting 
head  (figure  10).  Also,  note  the  valve  stem  position  to  the 
Mounting head. Use your free hand to press down on the tire 
opposite the Mounting head to  allow the bead  to utilize the 
drop center area of the rim, this position reduces stresses in the 
bead and allows an easier bead lift.

 

Figure 10 - Insert Bead Lifting Tool

 

11. Push the bead lifting tool down towards the wheel to lift 
the tire bead up and over the knob portion of the demount head. 
Hold the tool and bead in this position (figure 11).

 

Figure 11 - Lift Bead Over Demount Head

 

12.  Depress  the  table  top  pedal  to  rotate  the  wheel.  The 
Mounting head will guide the tire bead up and over the edge 
of the wheel. Continue rotation until the upper bead is de-
mounted. 
 

 

L. 

Push down on the tire across from the demount head 

during table top rotation to utilize the drop center area of the 
wheel. This reduces the tensional force on the top or first 
bead during demount (figure 10).

 

Figure 12 - Demounting Lower Bead

 

13. Lift and hold the tire at an angle so that the lower bead 
is resting in the drop center directly across from the de-
mount head, and is loose below the demount head (figure 
12). Insert the smooth curved end of the bead lifting tool 
down over the forward end of the mount/demount tool and 
below the lower bead. Lift the bead up and over the knob 
on the demount head (figure 13).

 

Figure 13 - Guide Lower Bead Over Tool Head

 

14. Depress the table top pedal to rotate the wheel. The 
demount head will guide the bead up and over the edge of 
the  wheel.  Continue  rotation  until  lower  bead  is  de-
mounted. 
 

 

M. 

With tube-type tires, demount the upper bead and 

remove the tube before demounting the lower bead.
