Lubrication of agitator axel
Control/Filling with grease of agitator's bearing
The agitator's bearing is filled with grease from the factory.
Refilling grease should take place during installation and then at
least twice per year.
Should be performed by trained personnel.
• Use grease with high temperature properties*.
* Order the maintenance service kit ST12335-00.
• Grease should be pumped in so that it is forced out through
the overflow hole on the bearing housing.
• Check the grease that is forced out. If it shows signs of being
mixed with water, the agitator's bearing and seal should be
removed for inspection and if necessary replacement.
