Before adjusting the return-to-dig, make sure that the actuating arm on the bucket linkage is not damaged. Slowly roll back and dump the bucket and make sure that the actuating arm stays the same distance from the switch. The switch mounting bracket protects the switch. Make sure the actuating arm cannot touch the switch when the bucket is dumped.
1. Park the machine on a level surface. Lower the loader bucket to the ground and rotate the bucket to the correct digging angle.
2. Apply the parking brake and stop the engine.
3. Position the switch guard (1) so the switch face is parallel to the actuating bar, refer to Figure 3.
