Condensate forming in the motor terminal board!
Condensate can form in the terminal board of the flameproof electric motors. For this
reason, we suggest that at regular intervals (at least once a year) you should stop the
mixer and remove the condensing water with a suitable absorbent cloth.
Before carrying out the above mentioned operations, read carefully the instructions in
paragraph 8.2.
8.1
Maintenance depending on wear level
All moving parts are subjected to wear, whose level depends on working time, operating
conditions and on the shocks they undergo.
The drive line oil has to be changed, the first time, after the first 200 operating hours and
then each 2000 working hours (at least every 2 years).
Remove the old oil , possibly still warm, only when the machine and the gearbox are not
working.
To fill the machine up with oil: 18 litres of Shell Tivela oil (or equivalent) are needed.
Both the mechanical seal as well as the drive shaft bearing have to be replaced each 20.000
operating hours.
The average service life of the expansion joint rubber part is about 8 years.
