8. Maintenance and repair
RISK of death due to electrocution!
There is a risk of fatal injury from electric
shock when working on electrical equipment.
With all maintenance or repair work, the
lifting unit must be disconnected from the
mains and secured against being switched
on again without permission. Damage to the
power supply cable may only be rectified by a
qualified electrician.
DANGER – explosive atmosphere!
An explosive atmosphere can form within the
collection reservoir. If the collection reser-
voir is opened, then this can form inside the
operating space. There is a risk of fatal injury
due to explosion! Take appropriate counter-
measures (e.g. appropriate replacement of
air) to avoid an explosive atmosphere in the
operating space!
The end-user is responsible for defining a
corresponding explosion zone. Observe the
following:

ardous to health or come into contact with such
fluids must be decontaminated. In addition, make
sure that no gases that are hazardous to health
form or are present.

hazardous to health, apply the first-aid measures
specified on the notice at the working premises
and notify a doctor immediately!
