NOTE: In the following step, consult the battery manufacturer's recommendations for the specific gravity. If unavailable, use the value stated in step 1.
1. Check the battery for an adequate charge. If the specific gravity is less than 1.145, replace or charge the battery. Adjust the BDI cutout correctly. 2. Check for shorts to frame. 3. Check the static strap. Clean or replace as necessary. 4. Make sure both guidance sensors are mounted on the truck centerline with no physical damage. 5.

Relearn the wire guidance frequency and offsets. See page 8- 10 and page 8-10. 8. Make sure the heading angle and distance from wire settings are configured correctly. See "Guidance Parameter Setup" on page 8-9. 9. Check for bent base legs. 10. Make sure the load wheels are not binding. 11. Check for excessive play in the drive unit radial ring. 12.
