FORDING - Continued
NOTE
1. Check both entry and exit slopes for maximum angles of 15 percent.
2. Check that water velocity is no more than 5 miles per hour (8 km/h). This is equivalent to 7 feet (2m) per
second.
3. Check bottom of stream to make sure that it is firm enough to support the BHL and that it is free of
underwater obstacles.
4. Set 4WD switch (Figure 3, Item 1) to Four-Wheel Drive (4WD) position.
5. Enter water at no more than 5 miles per hour (8 km/h) and maintain an even speed.
6. When clear of stream and on level terrain, make several gradual stops to clear water from service brakes
and to be sure brakes work properly.
7. As soon as possible, open tool box, make sure it has drained properly, and dry off the tools with wiping
rag to prevent rust or deterioration.
8. After fording, lubricate front and rear drive shaft slip splines (WP 0022).
