UNUSUAL ENVIRONMENT/WEATHER - Continued
Soft Or Muddy Area Operation
Do not engage differential lock when the BHL is turning or when one rear wheel is rotating
faster than the other rear wheel. Engage differential lock only when the BHL is moving in
straight direction. Failure to comply may result in damage to rear axle.
The differential lock should only be used temporarily to move the BHL through a soft or
muddy area. The differential lock will disengage automatically when the torque is released
from the machine.
For description and use of operator controls and indicators, refer to WP 0004 thru WP 0009.
1. Make sure the BHL is moving straight ahead and that rear wheels are rotating at same speed.
2. Push down differential lock switch (Figure 1, Item 1) and keep switch pushed down while the BHL moves
through soft or muddy area.
3. Release differential lock switch (Figure 1, Item 1) after the BHL has moved through area and keep engine
speed below 2,500 rpm.
