Preliminary checks
Check that there is a pressure of at least 8 bar on the pressure gauge of the Filter Reg
Lubricator unit.
Check that the machine has been adequately connected to the power mains.
Deciding from which side of the wheel the tyre must be demounted
See fig. 10.
Find the position of the drop centre A on the wheel rim. Find the largest width B and the smallest width C.
The tyre must be demounted or mounted with the wheel positioned on the turntable with the side
with the smallest width C facing upward.
Special instructions
Some types of wheels on the market require special procedures and precautions which differ from
the standard procedure.
This applies in particular to the following types of wheels:
Alloy rim wheels: some wheels have alloy rims where the drop centre A is very small or non-existent -
fig. 10-B. These rims are not approved by the DOT (Department of Transportation) standards - these
initials certify that tyres comply with the safety standards adopted by the United States and Canada
(these wheels cannot be sold in these markets).
DANGER
Take utmost caution when mounting the tyre. The rim and/or the tyre may be damaged
accidentally, with the risk of the tyre exploding during the inflation stage.
European style high-performance wheels (asymmetric curvature)
- fig.10-C: some European
wheels have rims with very pronounced curvature C, except in the area of the valve hole A where the
curvature is less pronounced B. On these wheels the bead must first be broken in correspondence
with the valve hole, on both the top and bottom sides of the wheel.
Wheels with low pressure indicator system
- fig.10-D.
