Figure 12.12: Agitator finger wearing zone
Measure the distance between the agitator finger and the base of the hopper.
If the measured distance exceeds 20 mm, the agitator finger must be re-
placed.
12.7 Checking the spreading disc hub
In order to maintain the ease of movement of the cap nut on the disc hub, it is
recommended to grease the disc hub (using graphite grease). Check the cap nut
for cracks and damages. Immediately replace defective cap nuts.
