Mobility
System
Concept
With
the
Mobility
System,
minor
tire
damage
can be
sealed
temporarily
to
enable
continued
travel.To
accomplish
this,
sealant
is
pumped
into
thetires,
which
seals
the
damage
from
the
inside.
General
information'xFollow
the
instructions
on
using
the
Mobility
System
found
on
the
compressor
and

of
the
Mobility
System

be

In
this
case,
have
the
elec#j

checked
and

information
DANGER
If
the

pipe
is
blocked
or
ventilation
is
in#j
sufficient,
harmful
exhaust
gases
can
enter
into the
vehicle.
The
exhaust
gases
contain
pollu#jtants
which
are
colorless
and
odorless.
In
en#j
closed
areas,
exhaust
gases
can
also
accumu#j
late
outside
of
the
vehicle.
There
is
danger
to
life.
Keep
the
exhaust
pipe
free
and
ensure
suf#j
ficient
ventilation.
NOTICE
The
compressor
can
overheat
during
extended operation.
There
is
