Park the machine on a smooth, level surface.
Shift the transmission direction control switch to the NEUTRAL position.
Lower the bucket or the work tool to the ground.
Engage the parking brake.

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.Prevent possible injury by performing the procedure that follows before working on the machine.
Connect the laptop computer to the service connector in the cab. The service connector is located on the right side instrument panel above the key start switch. Note: The Cat ET will allow the activation speed for the ride control to be adjusted in 0.1 km/h (0.06 mph) increments. The engagement speed may be adjusted between 1.6 km/h (1 mph) to 32 km/h (20 mph). The factory setting for the activation speed (forward) is 9.7 km/h (6 mph). The factory setting for the activation speed (reverse) is 3.2 km/h (2 mph).Note: The deactivation speed will be 1 km/h (0.62 mph) less than the activation speed.
Open the software program Cat ET. Select the "Implement ECM" from the "ECM Selector" menu.
Select the "Service" menu item from the toolbar. Select the "Configuration" menu item. Note: Activation of the software for the ride control without installation of the hardware for the ride control will introduce faults for the ride control switch and the solenoid.
