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 fi 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 profi 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.
