Operational Checkout

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 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. This information may allow you to perform a simple adjustment yourself which will reduce the down time of your machine. Use the table of contents to help find adjustment procedures.

The information you provide 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 design 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 the 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.

Start at the top of the left column and read completely down column before performing 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 section in this manual or to your authorized dealer for repair.

Steering System Leakage Check

                                                          Run engine at slow idle.

                                                          Switch differential lock to OFF.

                                                          Turn steering wheel right until frames contact stop.

                                                          IMPORTANT: Steering wheel must be "jerked" to shift steering valve into full flow mode. If wheel is not jerked, wheel will continue to move while slight pressure is exerted on it and simulate a leaking steering valve.

                                                          Hold steering wheel against stop, jerk wheel against stop, continue turning steering wheel using approximately 22 N (5 lb force) while counting steering wheel revolutions per minute. Repeat check to the left.

                                                          LOOK: Steering wheel must not turn more than 5 rpm.

                                                          NOTE: Use good judgement; excessive steering wheel rpm may not affect steering function during normal operation.

                                                          Go to next check.

                                                            Steer machine to right and left.

                                                            LOOK: Machine must steer approximately half-way to stops in both directions.

                                                              Secondary steering indicator and STOP indicator must come on and alarm must sound.

A new shock absorber will occasionally allow grapple-to-boom contact when operating on very rough terrain. If grapple swings too freely, the grapple may contact base of boom and damage grapple or boom.

Be sure winch clutch and brake engage in one second or less before doing this test. In cold operating conditions the transmission oil may be at operating temperature; however, the oil in the two winch hoses will be cold. This can cause delayed winch function operation.
