Travel Crawl Control
The travel system on the machine can be adjusted to make the attachment more effective in
tough digging situations. The travel “crawl” control allows the travel speed to be adjusted from
full speed forward or reverse to no movement at all. To adjust the travel speed using the crawl
control, move the engine throttle lever to the maximum engine speed and:
NOTE: Make sure that the High/Low travel speed switch (Item 3, Figure 3–36 ) is in the HIGH
position.
1. With the attachment raised off the ground, move the AUXILIARY control lever (Items 1, 2,
Figure 3–36 ) to either the FORWARD or REVERSE position.
Figure 3–36 Auxiliary Control
2. Lower and position the attachment in the work position.
a. Rotate the CRAWL control lever (Item 1, Figure 3–37 ) to adjust the travel speed as
needed.
Figure 3–37 Crawl Speed Adjust Control
b. Rotate the CRAWL control lever fully clockwise to the turtle, or NO TRAVEL position.
Full hydraulic power will be directed to the attachment and the machine will not move.
c. Move both travel control levers to the full reverse travel position.
