Operational Checkout Procedure

Use this procedure to check all systems and functions on the machine. It is designed so you can make a quick check of machine operation while doing both a walk-around inspection and performing specific checks from the operator's seat.

Should you experience a problem with your machine, you will find helpful diagnostic information in this checkout that will pinpoint the cause. Use the table of contents to help find adjustment procedures. This information may allow you to perform simple repairs yourself, reducing machine down time.

The information obtained after completing the operational checkout will allow you or your authorized dealer to pinpoint a specific test or repair needed to restore the machine to specifications.

A location will be required which is level and has adequate space to complete the checks. No tools or equipment are needed to perform this checkout.

Complete the necessary visual checks (oil levels, oil condition, external leaks, loose hardware, linkage, wiring, etc.) prior to doing the checkout. The machine must be at operating temperature for many of the checks.

Locate the check to be performed at the top of the left column and read completely down the column before performing the check. Follow this sequence from left to right. In the far right column, if no problem is found, you will be instructed to go to next check. If a problem is indicated, you will be referred to either a group in this manual or to your authorized dealer for repair.

Loader Return-to-Dig Check

                                                                            LOOK: Does the loader control lever disengage from the bucket rollback detent when the bucket is level?

                                                                            LOOK: When the bucket is at ground level, bucket must be level and the bucket indicator pointer must be aligned with mark on the boom pivot.

                                                                            NOTE: When return-to-dig is used with loader boom in full up position, the bucket leveling linkage will move the bucket control valve out of return-to-dig position before bucket is actually level.

                                                                            Go to next check.

                                                                              Put loader bucket in the rollback position with the boom near ground level.

                                                                              Raise the loader and at the same time hold the control lever in the bucket rollback position.

                                                                              Observe bucket and loader control lever as the loader rises.

When the loader control lever moves to activate the bucket dump function, does the bucket position remain stationary the remainder of the loader boom raise cycle?

                                                                              Go to next check.
