Cruise Control
Cruise control is an optional feature that allows the unit to automatically adjust ground drive speed to
digging conditions. In easier soil conditions, the ground drive speed will increase. When the unit
encounters difficult soil conditions, the ground drive speed will decrease. The unit does this by adjusting
ground drive pump output to maintain a preset engine rpm.
Operate Cruise Control
1. First set the following controls:
• ground drive controls to neutral
• gearbox shift control to low
• cruise control selector to MANUAL
• all other controls set as desired
2. Move cruise control rpm control to arrow at center.
3. Move cruise control selector to AUTO.
4. Following procedures on page 77, begin trenching to desired depth.
5. When desired depth is reached, ensure throttle is fully open.
6. Slowly move ground drive control fully forward.
7. Slowly adjust cruise control rpm control to match digging conditions.
8. When finished digging, move ground drive control to neutral, then move cruise control selector to
MANUAL.
9. Allow chain to dig itself free before stopping attachment.
EMERGENCY SHUTDOWN - Turn ignition switch to STOP.
IMPORTANT:
• In harder digging conditions, higher cruise control rpm setting may improve digging
performance.
• In easier digging conditions, lower cruise control rpm setting may increase ground drive
speed.
Incorrect procedures could result in death, injury, or property
damage. Learn to use equipment correctly.
NOTICE: Moving cruise control selector to MANUAL with ground drive control out of neutral
will cause machine to immediately move in the direction of the ground drive control. This can
result in injury or damage.
