Impact hazard.
Take care not to knock your head or any other part of your body
against the arm during extension.
Risk of crushing.
Never insert any part of the body, and in particular hands,
between the demount/mount tool and the wheel.
Preliminary checks
Check on the pressure gauge of the filter reg lubricator unit that there is a pres -
sure of at least 8 bar.
Check that the machine has been hooked up to the electrical mains correctly.
How to decide the side of the wheel from which to demount the tyre
See fig.8
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. 8a. These rims are not approved to DOT (Department of Transportation)
criteria - the marking which certifies the tyre’s conformity to the safety standards adopted
by the United States and Canada (these wheels cannot be sold on these markets).
DANGER
Take great care 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. 8b: some Euro-
pean wheels have rims with very pronounced curves 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. 10c: see “Procedure for wheels with
valve or band-type sensors”
