Setting the mounting head

5. Setting the mounting head
Before demounting or mounting a tyre make sure the
mounting arm is pushed fully to the rear and the mounting
head is in top position.
When handling several wheels of the same dimensions the
mounting head can stay in the working position set for the
first wheel.
So that alloy rims are not damaged when tyres are mounted
or demounted, application of the mounting head to the rim
has to be most careful. Furthermore it proved useful to adjust
clearances between mounting head and rim somewhat
larger than given in Fig. 15.

Fully depress the pedal (Fig. 14, Item 5). The machine
post is tilted into working position.

Move the mounting head by hand to the rim flange and
position onto the rim. Mounting nose and bead guide
roller might contact the rim.

lock the mounting head automatically in working position
with respect to height and lateral clearance (Fig. 15).

When mostly handling oversize tyres up to 22" or small 8"
tyres, you should readjust mounting head position function
of the rim diameter.
•
For this untighten fixing screw 1 of the mounting head
and readjust the two threaded pins 2 relative to each
other until the mounting head position suits for that rim.
Setting: The bead guide roller 4 protrudes about 6 to 7 mm
from the rim flange, the plastic protection (or steel roller) 3
contacts the rim flange.
•
After readjustment retighten the fixing screw 1.
