4.1 Intervals for maintenance purposes
The intervals between maintenance tasks depend largely on the operating conditions of the device.
Please observe chapter
1.1. General Information.
If operational irregularities are discovered during the operation or during a functional test,
unplanned maintenance work on the mixer is required. This must be performed as soon
as possible after the discovery of the deviation in operating behaviour.
Note
All O-rings which are replaced
(1.1 General information)
must be lubricated with silicone grease before installation
after the device maintenance.
