5.0 Mounting and Demounting - General
Precautions
Before mounting a tire on a rim, pay atten-
tion to the following:
A. The rim and all its parts must be clean and in good
condition: If necessary clean and paint it after remov-
ing all wheel-weights, including tape weights inside
the rim.
B. The tire must be clean and dry, without any dam-
age to the bead and the carcass.
C. Replace the rubber valve stem with a new one or
replace the “o” ring if the valve stem is made of metal.
D. If the tire requires a tube or a flap, make sure the
tube is dry and in good condition.
E. Lubrication is necessary to mount the tire cor-
rectly and get a proper centering. Be sure you are
using approved lubricant only.
F. Make sure the tire is the correct size for the rim.
5.1 Locking Rims
Lift the tool holder arm and move the tool holder car-
riage all the way out.
Put the wheel in vertically and roll it on the foot board.
Be sure to use alloy adapters when applicable.

If the wheel is very heavy be sure to use a
suitable external lifting device (i.e. fork lift,
crane etc.).
Close the jaws of the chuck and move the chuck
approximately to the center of the rim. Move the foot
board toward the chuck and move the chuck up-down
while opening the chuck arms until the rim is clamped
properly (fig.17).

CAUTION
Attention! The drop center of the rim (when it
exists) must be kept towards the outside of the
machine (fig.16).
