EEWH315A and 317A Tire Changer Operation Manual
Page 18 Operation Manual
MAINTENANCE NOTE:
IF THE MOUNT/DEMOUNT HEAD NYLON INSERTS
ARE WEARING OUT PREMATURELY, THE CAUSE IS
THE OPERATOR’S FAILURE TO CORRECTLY SET
THE RIM DIAMETER ADJUSTMENT KNOB, CAUSING
THE INSERT TO INCORRECTLY CONTACT THE RIM.
NOTE: ONCE THE MOUNT/DEMOUNT HEAD IS
POSITIONED PROPERLY, IDENTICAL WHEELS MAY
BE CHANGED WITHOUT HAVING TO RESET THE
HEAD.
F. Insert the mount/demount tool between the bead and
the mount/demount head. Pry the bead onto the mount/
demount head using the mount/demount head as the
leverage point. To make this operation easier, insure
that the bead of the tire, 180º across from the mount/
demount head, is in the drop center of the wheel. Push
the tire into the drop center with your hand or bead
depressor tool if necessary.
It is suggested that the mount/demount tool be removed
after lifting the bead onto the mount/demount head (Fig.
4.1-5), however, you may remove the tool after the bead
has been removed.

G. Rotate the turntable clockwise (pedal down) and, at
the same time, push down on the tire sidewall to move
the bead into the drop center of the rim (Fig. 4.1-6).

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.
