Metering unit maintenance
The metering unit requires no special mainte-
nance.
To avoid repair-related downtimes, the meter-
ing unit and drive motor should be cleaned at
the end of the season and checked for correct
function.
In particular, the bearings in the side cover and
on the drive motor can be damaged and/or be-
come sluggish as a result of dressing dust.
Replace the bearings in good time if necessary,
or keep a stock of spare bearings.

However, the use of crimping contacts is recom-
mended.
