20. Instruct in use of DATAVISION system.
21. Demonstrate how to use the systems by running
through the menus. Explain how to operate/calibrate
and adjust, for example: Constant Flow, Auto Level
table, Auto Level machine, etc.
22. Explain the forward speed indicator and shaft speeds.
23. Explain how to use the monitoring system:
•
How it gives warning of a malfunction and, in the
event of a serious fault such as engine overheating,
low engine oil pressure or lack of oil in the hydraulic
system, will stop the engine if the warning is ignored.
•
Show how to prevent an engine stop if required for
road safety reasons.
•
How to zero the trip counters that enable the operator
to check the number of hours worked and hectares
harvested in the course of a day. The cumulative
number of hours and hectares cannot be zeroed and
acts as a log for the owner.
24. Demonstrate and explain the switches on the multi-
function lever and control panel.
25. Explain engagement and disengagement of the
threshing unit, table drive and unloading auger. Use of
table auger reversing.
26. Demonstrate how to change the concave setting elec-
trically/mechanically.
27. Show how to set the clearance between the rotary
separator and concave.
28. Explain operation and alteration of cylinder speed.
29. Demonstrate how to vary fanning mill speed. Explain
the necessity of regular cleaning inside the fanning
mill guard.
30. Demonstrate sieve adjustment, including the top
sieve extension, electrical/manual.
31. Demonstrate and explain adjusting the straw deflec-
tors in the straw chopper, electrical/manual.
32. Demonstrate mounting and dismounting the cutting
table and explain table alignment.
33. Demonstrate hydraulic operation of the cutting table
up and down. Explain how to use and adjust the auto-
matic table functions. Point out that if the cutting table
is lowered all the way, the oil pressure in the accumu-
lators will be reduced and the cutting table will lose its
floatation.
34. Demonstrate hydraulic operation of the reel up and
down, forward and back/reel speed and automatic
reel control.
35. Demonstrate hydraulic operation of the unloading
auger.
36. Demonstrate sampling from the grain tank.
37. Show how to swivel the cab ladder forwards for trans-
port on public roads.
38. Demonstrate the location and use of all the fuses.
39. Demonstrate the settings and control lever for posi-
tioning the reel spring tines correctly and how to
adjust the reel for special crops.
