CLAMP 1498750 - Caterpillar

Introduction
To calibrate the assist system use the Assist Fine-Tune Calibration procedure. Use the following procedure to adjust the Assist cracking point configuration parameters. This adjustment will allow for more operator accuracy and controllability while using the assist features.Note: The changes to these parameters will affect all Assist features.Note: To disable or reset this calibration, change the value contained within the Assist cracking parameters to 0%, the default value.Adjustment Preparation
Place the machine controls at the following settings: engine speed dial "7" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Increase the hydraulic oil temperature above 40° C (104 ° F).Adjustment Procedure- Fine-Tuning for Grade Assist

If the machine is operating with grade assist active and the following behaviors occur, perform the following manual tuning.The Boom Drops at the Beginning Point With Minimum Stick In Lever From a Maximum Reach Position
Decrease the "Stick In Cracking Point", or increase the "Boom Raise Cracking Point #2" in 0.5% increments. An example of this increase, is to change the parameter value from 17.0% to 17.5% to 18.0% to 18.5% as needed.The Boom Drops at the Beginning Point With Minimum Stick Out Lever From a Minimum Reach Position
Increase the "Stick Out Cracking Point", or increase the "Boom Raise Cracking Point" in 0.5% increments. An example of this increase, is to change the parameter value from 17.0% to 17.5% to 18.0% to 18.5% as needed.Grade Assist Function "Fine" Mode Active
Illustration 5 g06346659Note: The boom raise speed is not fast enough.Increase the "Boom Raise Modulation Scale" from the value of "5".Adjust the "Boom Raise Modulation Scale" from the value of "5".Adjust the "Boom Lower Modulation Scale" from the value of "5".Adjust the "Boom Raise Modulation Scale" from the value of "5".Adjust the "Boom Lower Modulation Scale" from the value of "5".The Boom Drops Around Vertical (When Switching From Boom Up Operation to Boom Down Operation)
Increase the "Boom Lower Cracking Point", because the value might be lower than the actual cracking point.Note: This value has a "-" negative sign. An example of this change, is to change the parameter value from -22.00% to -20.00%.The Boom Oscillates During Stick In With Bucket Assist
Decrease the bucket dump cracking point value in increments. The value may be higher than the actual cracking point value.
Check the boom raise cracking point.
Return the bucket dump cracking point to the original number.
Increase the boom raise cracking point incrementally.
Decrease both the bucket dump cracking point and the boom raise cracking point.Check Procedure - Grade Assist
