NECESSARY TO MOUNT THE TIRE CORRECTLY AND 
GET A PROPER CENTERING ON THE RIM. BE SURE 
YOU ARE USING APPROVED LUBRICANT ONLY.

NOTICE!
SOME TIRES HAVE A COLOR DOT THAT IS TO BE 
KEPT ON THE OUTSIDE OF THE WHEEL AND IS TO 
BE ALIGNED WITH THE VALVE STEM. IF THIS IS THE 
CASE BE SURE TO ATTAIN PROPER ALIGNMENT 
PRIOR TO TIRE INFLATION.

NOTICE !
ON VEHICLES WITH TPMS SENSORS, LOCATE THE SEN-
SOR (USUALLY WITH STEM) 90 DEGREES FROM THE 
MOUNT/DISMOUNT HEAD. DAMAGE TO THE WHEEL AND/
OR SENSOR  WILL RESULT IF THE BEAD CONTACTS THE 
TPMS SENSOR DURING THE MOUNT PROCEDURE.

B.

 Lock the rim to the turntable and rotate it so that the 

valve is at the 2 o’clock position.  Place the tire to be 

mounted on the rim. Tilt the column forward in so that the 

mount/demount head is in the working position. (Fig. 4.2-

3)  Position the lower bead on top of the mount/demount 

head  and UNDER the mounting  f nger  of the mount/

demount head (Fig.  4.2-3).  Turn the wheel clockwise 

(right pedal down) while simultaneously pushing the tire 

down into the drop center, opposite to the mount/demount 

head. For this operation the 14 RPM Pedal Position can 

be used.

C.

 Mount the upper bead following the same directions in 

section B. With low prof le tires the Bead Holding Clamp 

(optional part # EAA0247G70A) or the PBA device (See 

chapter  5.3), can help to prevent the top bead from  

prematurely seating during the mounting cycle. For this 

operation the 7 RPM Pedal Position can be used.

NOTE

:  Bead Holding Clamp must be removed prior to 

coming full circle and impacting the mount/demount head.
