DIFFERENTIAL LOCK OPERATION
0005
C AU T I O N
Excessive wheel spin and uncontrolled wh el spin can cause accelerated wear to
e
powertrain components and tires.
Improper use of differential lock controlmay damage components of differential lock.
1. Engage differential lock control to prevent wheel slippage when traction is poor. Power will be equally
distributed to each wheel, causing both wheels to turn at the same speed.
2. Anticipate using differential lock before wheel slippage occurs. Do NOT engage differential lock while one
wheel is slipping. Decrease engine rpm until wheel stops spinning, and then engage differential lock.
3. Do NOT engage differential lock at high speeds.
4. Do NOT turn (steer) machine while differential lock is engaged.
5. Differential normally unlocks when pedal at floor is released. In areas of high resistance, it may be necessary
to turn machine SLIGHTLY and decrease engine rpm to assist in unlocking differential lock.

STEERING OPERATION
0005
1. Operator controls machine direction using steering wheel.
2. Avoid over-steering. Become familiar with steering characteristics of machine before attempting maneuvers in
limited space.
3. In the event of a steering system malfunction (alert indicator, action light, and action alarm all activate), the
secondary steering system will engage allowing the operator to steer machine immediately to a safe location.
Secondary steering will operate only while moving in a forward direction.
a. Secondary steering enables you to steer machine to a safe location. Apply service brakes and bring
machine to a stop. Engage park brake.
b. Shut down engine and troubleshoot malfunction.
c.
Do NOT operate machine until problem has been corrected.
