DRIVING OPERATION
Recommendation
Before switching the switch of multiplier on the dashboard, do the manual shift of multiplier gear when using H and L buttons
(once by H button and once by L button) on gear shifting lever with requested engine revolutions. The values (engine revolutions)
will be saved and after subsequent engagement of the multiplier pre-selection switch on dashboard, the system of automatic mul-
tiplier shifting will automatically shift multiplier gears according to these engine revolutions
With multiplier pre-selection switch on, in case of release of travel clutch, for example with gear shifting, stopping and subsequent
dead start of tractor or while using reversing, the system of automatic shifting of multiplier sets an applicable multiplier gear with
subsequent switch of travel clutch.
