Risks
during

the
following
safety
devices
have
been
used:

a
maximum
pressure
valve
placed
inside
the
hydraulic
unit
to
prevent
excessive
weight.
z
a
special
design
of
the
hydraulic
system,
in
case
of

failure,
to
prevent
sudden
lift
lowering.
The
maximum
pressure
valve
has
been
preset
by
the
manufacturer
to
a
proper
pressure.
DO
NOT
try
to
adjust
it
to
overrun
the
