CHAPTER 3 – INSTRUMENTS AND CONTROLS
Graders Operations With FUNK Transmission
885B models with FUNK Transmission The transmission control lever is used to select the desired forward or rearward speeds. These machines are equipped with a 8 speed forward and 4 speed reverse transmission. The gear shifting is performed through an electronic selector which function is also to avoid an improper gear shifting. The desired gear (1st, 2nd, etc) as well as the travel direction (forward or reverse) can be chosen through this selector.
The front panel is equipped with a digital indicator that shows in which gear the transmission is engaged. If the display shows an “error code” it means that some fault has occurred in the transmission system. Therefore it is necessary to contact a CASE dealer. With the machine stopped, when the selector lever is moved (to forward or to reverse position), the transmission automatically selects the 1st gear according to the chosen travel direction (1st forward or 1st reverse). The remaining gears selection can be performed by a simple touch to the right (speed increase) or to the left (speed decrease), on the selector lever. The digital display will always indicate the travel direction and in which gear the transmission is engaged. When the machine is stopped, any gear lower than F3 or R2 can be selected to move again.
The command positions for the gearshift lever are the following: F - Forward
Lock Ring
N - Neutral R - Reverse DS - Down shift US - Up shift
70
The neutral lock is a device that holds the lever blocked (transmission in neutral) avoiding this way its undesired movement. To select the forward or reverse gears the lock-ring must be pulled upwards, hold it in this position and move the gearshift lever to the desired position.
