Measures

1. Comply with the instructions in the machine documentation.
2. Comply with the safety instructions and carry out all steps as described
above in section "Deactivation".
3. Before disassembling the motor and the supply lines, secure them
against dropping or movements. Subsequently, disconnect the mechani‐
cal connections. Discharge the coolant ducts at MAF motors.
4. Dismount the motor from the machine. Store the motor properly!
5. Document all executed measures in the commissioning report and the
machine maintenance plan.
Asynchronous motors of the MAD/MAF series are maintenance-free as long
as they are operated under the specified operating conditions and during
their service life. Operation under unfavorable conditions can, however, lead
to restrictions in availability.
● Increase availability with regular preventive maintenance measures.
Comply with the machine manufacturer's instructions in the machine
maintenance plan and the maintenance measures described below.
● Record all maintenance measures in the machine maintenance plan.
WARNING
● Do not carry out any maintenance measures while the machine is run‐
ning.
● Before starting maintenance, switch off the controller and the machine
and wait until the discharge time of the electrical systems has elapsed.
● While carrying out maintenance work, secure the machine such that it
cannot restart or be used by unauthorized persons.
● Do not work on hot surfaces.
Bosch Rexroth recommends the following maintenance measures, based on
the maintenance plan of the machine manufacturer:
