Description of Change: A method is available for storing the mud guards for roading on the listed machines. This protects the mud guards from damage when the machine is being transported.
 | |
| Illustration 1 | g01266465 |
A typical example of a mud guard that is shown in the correct position for roading | |
Before transportation, fix both mud guards into the position that is shown in Illustration 1. Ensure that the eye in the mud guard is properly installed over the retainer on the body and that the fastener is correctly positioned in order to secure the mud guard.
After transportation is complete, return the mud guards to the operating position.
Adaptable To: The mud guards that are listed in Table 1 have been improved in order to allow the deflectors to be stowed in a position that avoids damage to the deflectors during transportation.
| Affected Mud Guards | ||
|---|---|---|
| 725 | (S/N: AFX) | 170-1674 |
| (S/N: B1L) | ||
