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.

WARNING: MOVE YOUR HANDS AWAY FROM
THE RIM BEFORE OPERATING THE TOOL DOWN-
STROKE.
E. Gently position the mount/demount head in contact with
the rim edge and lock it into place: the tool automatically
moves away from the rim edge vertically and horizontally,
approximately 1/25” (1 mm): this is necessary to avoid
any rim contact during the changing process. (Fig. 4.1-4).

4.1.1 ANGULAR TOOL ADJUSTMENT
The tool is adjusted at the factory with an optimal angle
for most wheels used today. However, the angle can be
optimised for wheels with a diameter that differs conside-
rably from the standard.
To adjust the tool angle, proceed as follows:
1. Mount the rim for which the adjustment is required.
2. Loosen the lower screw ( 1 , Fig. 4.1-5).
3. Adjust the tool with the screws shown ( 2a and 2b ,
Fig. 4.1-5). Unscrew the screw ( 2a or 2b , Fig. 4.1-5)
to rotate the tool, respectively clockwise or counter-
clockwise.
4. Screw in the opposite screw to block the tool in the
desired angular position.
5. Tighten the lower screw ( 1 , Fig. 4.1-5) with a torque of
35 Nm.
