clean the system every 30 ha. The rollers can be cleaned by setting the feeding quantity to zero and
back to the desired value. Then you must keep the above-mentioned setting instruction in mind –
turn first ½-1 turns over the desired setting and then return to the correct setting.
NOTE! Do not turn the hand wheel violently to zero. Rotate the feeding shaft simultaneously.
Instructions for the sowing chart and calibration test are given later in this booklet.
8.2 Bottom valves
Feeding accuracy depends on the distance between a bottom valve and a feeding roller. Therefore
it is very important that the bottom valves are in correct position and that they will not be readjusted
after calibration test without repeating the test (picture 13).
The bottom valves are spring loaded in order to avoid damage in case a harder object gets between
a bottom valve and a feeding roller.
Regulation positions of the bottom valves:
