AUTOMATIC Mode
For automatic mode selection press the lower part of the
mode switch (2) of the transmission, on the side panel.
A blue LED will turn on and the indication "A" will appear
on the front panel within the gear symbol.
The automatic mode can be used for transport as well as
for operation.
On automatic mode the transmission shifts gears auto-
matically according to the speed and load in which the
machine is submitted, not being necessary the operator's
interference for the appropriate gear selection.
The transmission has an electronic control system that
engages the selected gear only after the parking brake
has been released. When releasing the parking brake
maintain the service brakes pedal pressed down.
Move the selector lever forward (F) or reverse (R) position,
to select the desired travel direction. Release the service
brake pedal, accelerate the engine and start work.

"Kickdown"
KICKDOWN SWITCH
The operator can cause the speed decrease in automatic
mode, any moment he notices an unexpected increase of
leveling load on, by just pressing the "kickdown" switch
on the upper part of the gear shift lever. As soon as the
leveling load is reduced, the transmission will shift auto-
matically, selecting the appropriate gear for the work.
Declutch function
The declutch function is used to permit the engine to in-
crease its rpm and supply additional hydraulic fluid to the
implements in order to obtain a higher operation speed.
Press the lower part of the declutch switch (1) and the
brake pedal, to disengage the transmission. Release the
brake pedal to engage again the transmission.
NOTE: The declutch function is limited to gears 1, 2, 3
forward and 1, 2 reverse. Clutch gear reengagement is
only possible with engine speed below 1500 rpm.
