Cleaning

The fan speed is shown on the
CEBIS screen. The speed range
of the fan is 750rpm – 1600rpm.

With the standard cleaning on the
LEXION 670-620 machines there
are two other adjustments.

•

The wind board

•

The wind throttle

1.Wind board adjustment loosen
nut 3 and adjust. Towards the
rear of the machine more steeper
the angle for the air.

2.To adjust the wind throttle pull
out lock and move lever.

Use these two settings with the
fan speed.

TIP.

Steeper angle for heavier

crops and a lesser angle for
light crops.

TIP.

Open the wind throttle for

heavier crops and shut it for
lighter crops.

Approximately 90% of the grain needs to be separated from the straw by
the time the crop leaves the drum. This means that the remaining 10%
has to be separated by the walkers.

35

TIP.

Only make adjustments of 50rpm at a time.
