Pre-Start Inspection and Operation
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 2, Figure 3–32 ) is in the HIGH
position.
1. With the attachment raised off the ground, move the AUXILIARY control lever (Item 1,
Fig-
ure 3–32 ) to either the FORWARD or REVERSE position.
Figure 3–32 Auxiliary Control
2. Lower and position the attachment in the work position.
3. Activate the crawl control by rotating the CRAWL VALVE to the ON position. The travel
speed CRAWL control (Item 1, Figure 3–33 ) is now active.
