If the machine is running on operational conditions, a value
of about 720 - 750 r/min is indicated.
The speed indication allows to reliably evaluate the state
and load of the combine against the header.
Dropping speeds signal either an insufficient belt tension or
overload of the combine drive.
Stripping plate adjustment
Subject to the position of the stripping plates, a certain
number of green (G), yellow (Y) or red (R) diodes light up.
The more the stripping plates are open, the more diodes
are lighting up.
The number of the flashing diodes is only to be seen
on the monitor. Before the start-up, the proportion of
the flashing diodes to the position of the stripping
plates as a function of the harvest conditions is to be
determined.
Prior to checking, Diesel motor
to turn off! Keep your hands off the
stripping plates!
Recording tachometer
The recording tachometer (S) is located between two rows
on the drive connection claw of the Centaflex-coupler.
The distance between the magnetic switch (S) to the
magnet (M) and/or claw should at least be 1,5 mm and at
max. 2,5 mm.
Rheostat of stripping plate adjustment
