This screen contains the duty cycle information for the lift sensor. Verify that the lever is centered. Record the percent duty cycle of the lift position sensor.Note: The percent duty cycle for the lift position sensor must be between 46% and 54%. If the sensor reading is outside this reading, follow adjustment procedure ""Control Lever has Excessive Play in the Tilt Direction When at the Hold Position"" or ""Control Lever Has Excessive Play Around the Hold position in the Lift Direction"".Note: The duty cycle measurement may be slightly different between the Electronic Technician and a digital multimeter. Use the same tool throughout the entire procedure.

Subtract 21% from the reading taken in Step 11. For example, if the recorded center position was 47%, then 47% minus 21% equals 26%. This will be the sensor reading when the lever is at the maximum LOWER position.
Push the lever forward until the detent is felt.
Adjust the lift detent until the reading of the lift lever sensor is at the value calculated from Step 11.
Release the lever to the center position and tighten the locking nut on the detent adjustment.
Move the lever forward and verify that the start of detent is still at the calculated value from Step 11. If detent has shifted, repeat Steps 13 through 14.
Ensure that the lever is centered. Turn the keyswitch OFF, then turn the keyswitch ON. Do NOT start the engine.
Place the implement lockout switch in the OFF position.
If the blade is not resting on the ground, slowly lower the blade by moving the lever forward.
View ET Status Screen 1. Observe the current of Lower Solenoid 1.
Move the lever to the maximum LOWER position while the blade is resting on the ground. The lower current should increase to the maximum modulation current of 55% to 75%. At no time should the current increase to 100 percent. A current of 100% indicates FLOAT. If the current reads 100% at the start of detent, repeat Steps 8 through 15.
Slowly move the lever into the detent position. Approximately halfway through the detent position, the current of the lower solenoid should increase to 100%.
Allow the mechanical stop to hold the lever in the detent position. The lower current should remain at 100%. If the current drops to the maximum modulation current of 55% to 75%, repeat Steps 8 through 15.
Move the joystick to the HOLD position and turn the keyswitch OFF.Adjusting the Hydraulic Electronic Controls Using a Digital Multimeter
Ensure that the key switch is in the OFF position. Make the following connections to the harness that is connected to the lift lever position sensor.
