Always specify the machine type and machine number when
ordering spare parts. This and other information about the machine
are located on the nameplate under the main switch of the control
cabinet.
When carrying out maintenance work on fluid systems (hydraulic,
lubrication, and pneumatic systems), make sure before starting the
work that the respective system has been depressurized
(accumulator drain valve / manual slide valve / emergency stop).
Safety Instructions
Maintenance is to be performed only by authorized and trained personnel. This
applies particularly to work on motors (spindle motors) or other electrical
assemblies. The instructions in the respective manufacturer documentation must be
followed for such work.
We recommend the use of original spare parts and accessories. For damages
caused by the use of parts from third-party providers, liability and warranty are
excluded. The use of such products may change the structural characteristics of the
machine and negatively affect the active or passive safety.
In general, maintenance is to be carried out with the machine turned off. The main
switch must be locked out. Even when the main switch is switched off, parts of the
machine (e.g., the control cabinet light) may still carry electricity. These parts are
labeled. In a few cases, maintenance work needs to be performed with the machine
turned on (e.g., replacement of backup batteries). These maintenance activities
must be carried out with special care.
Prior to working on the machine, it must be allowed to cool down, as hot parts may
be located under the covers.
All maintenance work on the machine must be carried out with utmost care.
Fasteners must be loosened carefully and parts must be secured against falling
down. When elastic items (springs) are removed/replaced, appropriate devices
must be used. Any (non-horizontal) axes that pose a risk of falling down must be
moved to their end positions or secured against falling down. Pedal switches must
be put aside to avoid inadvertent actuation.
For removing machine parts, suitable lifting gears must be used. Removed machine
parts must be placed in a safe position and secured against falling over.
When the control cabinet is open or the machine covers are open or removed, no
cellular or wireless phones may be used within a 2 m radius.
Flexible hydraulic hoses made of elastomer-based plastics are subject to a natural
aging process and should be replaced regularly. The machine operator is
responsible for compliance with the laws and regulations of the country of use with
regard to the use of hydraulic hoses. In Germany, the relevant institutions
recommend a renewal cycle of 6 years for the hydraulic hoses.
Damaged power supply and fluid lines must be replaced immediately.
It may be necessary to remove or disable protective equipment to carry out repairs.
Any removed protective equipment must be reinstalled immediately after finishing
the repair.
