Maintenance
Operation and maintenance manual
KHO/340/EN/1.0.0. 21
Unlike the grease-lubricated model, the water-lubricated model cannot be
run dry since the water lubricated rear end bearing requires a constant water
supply in order to ensure adequate lubrication. The water-lubricated rear end
bearing is an open system, and its maintenance interval depends on water
quality.
The rear end bearing of the grease lubricated model is lubricated with
petroleum jelly through a grease nipple. The lubrication channel runs from the
grease nipple to the rear bearing housing.
The properties of the grease to use are described in appendix 2.

4.4. Control system
The joints and shaft bushings that belong to the control systems are essentially
maintenance-free, but lubrication prolongs their operating life. Locations
where waterproof petroleum jelly should be added during maintenance are
marked in figures 15–16. When the plastic bearings of the joints wear and
gaps are created, they must be replaced.
