Damage to the
piston
Leak on the handhold Increase load? Load increase
(e.g. something
has fallen onto the
part to be lifted,
thereby suddenly
increasing the
load) Secure the loads and
move them by using
other tools
Position ram on a
different place, where
the load to be moved
is lower
Use supporting
equipment to move
the load.
Is the set pressure
on the pump
adapted to comply
with the maximum
permissible
pressure for
the rescue
equipment? Pressure release
in the Rescue tool. Following the
reduction in pressure,
no further leak is
present.
Should, however,
there be a further
leak on the handhold,
immediately
deactivate the rescue
equipment, and
contact an authorised
dealer or LUKAS
itself.
