4. Specific maintenance instructions
Do not carry out maintenance unless the system is safely de-energised and depressurised.
Danger
4.2 Tightening torques
M
A
Screws and nuts without a specification of the tightening torques are tightened according to the commonly available
tables for screw dimensions and qualities using an appropriate tool. Parts with an explicitly specified tightening torque
(see spare parts drawing) are to be tightened to the specified value with a torque wrench (see Table 4).
4.1 Intervals for maintenance purposes
The intervals between maintenance tasks depend largely on the operating conditions of the device. For this purpose,
please observe chapter
1.1. General Information.
If operational irregularities are discovered during the operation or during functional tests, unplanned
maintenance work on the mixer is required. This must be performed immediately after the discovery
of the deviation in operating behaviour.
