GRADERS OPERATIONS WITH FUNK TRANSMISSION

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 command positions for the gearshift lever are the following: F - Forward N - Neutral R - Reverse DS - Down shift US - Up shift 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.

Lock Ring

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.

Operation Instructions – FUNK Transmission

Starting engine. Parking brake. Starting machine.

Inching pedal. Transmission must be in neutral and park brake on before engine can be started. Transmission will not engage a gear with park brake on. Move the selector lever to the desired gear, by pulling the safety ring under the knob (the display will indicate the selected gear). The inching pedal can be used the same way as the clutch pedal. Most operators use this procedure as normal operation for a smother starting. Use when starting or stopping. Use for grader finishing work requiring “ Creeper gear” or very slow speeds. Use for very slow ground speed work to increase engine speed for hydraulic performance (This should rarely be necessary because of the wide range performance of the hydraulic system). WARNING: Do not abruptly depress and release inching pedal to start a heavy load or free a stuck machine.

Upshifting.

Downshifting.

Shifting while descending steep grades.

Shifting forward to reverse and reverse to forward. Upshift normally as speed, grade, and traction conditions permit.Power shift, do not use inching pedal. Downshift one range at a time. Do not lug down the engine below 1700 RPM. Watch tachometer. Power shift, do not use inching pedal. During transport while descending short, steep grades, the engine may be driven from the ground by the wheels. In order to maintain a higher speed it could be necessary to upshift to protect the engine while using brakes for retardation. Normally the safe and recommended procedure is to descend slowly using a lower gear together with the brakes, particularly for longer distances. Operator can make these shifts as required by normal working conditions. The transmission will automatically select the appropriate gear in the opposite direction and has built in shock protection.

Lugging engine down under heavy blade or ripper load. Do not repeatedly depress and release inching pedal to force movement of machine.

Stopping and starting with display indicating a gear higher than 3.

When moving and then stopping with the inching pedal depressed, the machine will always select 4th gear to start. On level terrain or moderate grades start in 4th and upshift as conditions permit. On steep grades or when under load shift to lower gear and drive away. Study SAFETY RULES and BEFORE OPERATING, in the front of this manual thoroughly for the protection of machine and safety of personnel.
