Pay extra attention during this operation as it is easy
to mistakenly keep your foot on the bead breaking
pedal too long. This could potentially result in bead
or rim damage (Fig. 4.1-2)

NOTICE !
ON RUN FLAT TIRES WITH THE OPTIONAL LOW
PRESSURE SENSOR INSTALLED, BREAK THE
BEAD AT 90 DEGREES OFFSET FROM THE VALVE
STEM. DAMAGE TO THE WHEEL AND/OR SENSOR
MAY RESULT IF THE BEAD IS BROKEN AT ANY
OTHER POINT ON THE RIM.
C.
Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the outside and expand
clamps to clamp from the inside.
When clamping small wheels (14" or smaller) from the
outside, set the clamps at a diameter nearly equal to
the rim diameter before placing the wheel on the
clamps. This will help avoid the possibility of pinching
the tire as the clamps retract.
NOTICE !
TO MINIMIZE THE RISK OF SCRATCHING ALLOY
OR CLEAR COATED RIMS, THESE RIMS SHOULD
BE CLAMPED FROM THE OUTSIDE.
D.
Liberally lubricate both beads. Place the wheel
WITH DROP CENTER UP
(Fig. 4.1-3a) on the
turntable, and clamp in position. It may be necessary
to hold the tire and wheel down while clamping to insure
contact between rim and clamp as shown in 4.1-3a.

E.
Gently position the mount/demount head in contact
with rim edge, now manually push the lock lever up
and lock it into place. The mount/demount head
automatically moves vertically up and away from the
rim edge. Turn the swing arm adjustment knob
clockwise until the mount/demount head moves
horizontally away from the rim flange by approximately
1/16" (2mm): this is necessary to avoid any rim contact
during the changing process. (Fig. 4.1-4).

NOTE:
YOUR MACHINE IS SHIPPED WITH SEVERAL
REPLACEMENT PLASTIC INSERTS (INSIDE
STANDARD EQUIPMENT PACK). THE PLASTIC
INSERTS WILL HELP AVOID DAMAGE FROM
ACCIDENTAL CONTACT BETWEEN THE MOUNT/
DEMOUNT HEAD AND THE RIM. THE PLASTIC
INSERTS WILL NEED TO BE PERIODICALLY
REPLACED.
