Maintenance

Maintenance work must only be conducted when the machine is shut down. Additionally,
the main switch of the washing machine must be switched off and locked.

Existing safety systems must not be removed!

A functional test on all safety systems of the machine / installation is carried out during
every regular maintenance

We recommend you conclude a maintenance contract with our agency to guarantee a long
service life of the washing machine.

21.1

Basic safety measures during normal operation

Observe the maintenance intervals prescribed in the operating instructions!
Observe the maintenance instructions for the individual components!

Cordon off access to the operating area for unauthorised persons before starting mainte-
nance or repair work. Display a sign drawing attention to the maintenance or repair work!

Before carrying out any maintenance and repair work, switch off the electrical power at the
main electrical power switch and secure the switch with a padlock! The key for this lock
must be kept in the hands of the person carrying out the maintenance and repair work!
Failure to observe these precautions can result in severe injury or damage to property.

Before carrying out any maintenance and repair work, ensure that all the parts of the ma-
chine that may be touched have cooled down to room temperature!
Environmentally hazardous lubricants, cooling or cleaning agents must be disposed of cor-
rectly!

21.2

Before putting back into operation following maintenance or repair
work

Before starting operations following maintenance or repair work, all initial tests must be
carried out as described in “Machine Settings for Initial Commissioning by the Service En-
gineer”.

21.3

Observe environmental protection regulations

For all work on or with the machine, observe legal requirements relating to the avoidance
of waste materials and to their recycling/removal!
In particular, during installation, repair and maintenance work, materials that could pollute
water such as:



Grease and oils



Hydraulic oils



Coolant



Cleaning fluids containing solvents

must not be allowed to pollute the substrate or enter the sewerage system! These materials
must be stored, shipped, collected and disposed of in suitable containers!
