Creeper speed control button located on the soft panel switch
Push down on the creeper speed control button in order to activate the creeper speed control.Note: The indicator light will be illuminated when the creeper speed control is activated.
Set the engine speed dial at the correct speed.Note: Refer to Table 4 for the correct speed.
Fully depress the travel pedal.
Check the transmission output speed and engine speed in Electronic Technician.
Table 3
Target Shaft Speed (1)     =     Engine Speed     ×     Calculated Factor    
( 1 ) Refer to Table 4 for the correct engine speed and the calculated factor.
Calculate the target shaft speed.Note: Refer to the formula in Table 3 in order to calculate the target shaft speed.
Compare the transmission output speed with the calculated target shaft speed.
If the transmission output speed and the calculated target shaft speed are different, refer to the "Adjustment Procedure" to adjust the maximum displacement.Adjustment Procedure
Illustration 9 g02402417
Main pump and swing pump (2) Adjustment screw
Personal injury or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.
Remove the cap from adjustment screw (2) .
Turn adjustment screw (2) clockwise in order to increase the maximum displacement and turn adjustment screw (2) counterclockwise in order to decrease the maximum displacement.Note: Always make the final adjustments as the flow increases.
Install the cap onto adjustment screw (2) .Worksheet
