Risk of crushing.
Never place any part
of the body between
the bead breaker shoe,
the rim and the rim sup-
port.
When securing the rim
on the table top, never
place your hands be-
tween the sliding clamp
and the rim.
NEVER stand behind
the machine.
During lowering of the
mount/demount head,
never place your hands
between the wheel and
the head.
D Wider side - You cannot mount tyres from this
side
The two sides may be almost identical, but
only the narrow side serves for tyre mounting
and demounting
Identify the side for tyre mounting and make sure
that this side is facing upward when you install
the tyre on the table top (i.e. facing toward the
mount/demount head)
Special instructions
Alloy wheels
Some alloy wheels on the market have minimal
rim channels or are even completely without
rim channels (these wheels are not DOT ap-
proved).

DANGER
When working these wheels it is possible to
damage the tyre, the rim or both, with the risk
of the tyre exploding under pressure causing
serious injury or death. When mounting tyres on
this type of wheel, use the utmost caution.
European style high performance wheels (asym-
metrical curvature)
Some European wheels have very pronounced
curves on the rim edge, except in the area of the
valve hole. On this type of wheel bead breaking
must be performed in correspondence with the
valve hole and on the lower and upper side of
the wheel.

Wheels for Corvette, BMW, Lamborghini and
other wheels with "Low pressure indicator
system"
Some types of high performance wheels are
equipped with a pressure transmitter secured
to the rim with a belt on the side opposite the
valve hole. On this type of wheel bead breaking
must be done initially in correspondence with
the valve hole, on both sides of the rim.
