Maintenance of metering
unit
The metering unit does not require any special
maintenance.
In order to avoid repair related downtimes, both
the metering unit and the drive motor should be
cleaned and subjected to a function test after the
end of the season.
The bearings in the side cover in particular can
be damaged or may become hard-moving be-
cause of dressing dust.
If necessary keep bearings in stock and replace
in due time.
