OPERATION
CRAWLER WIDTH SWITCHING
Operate the machine with the maximum
crawler width
• Always operate the machine with the
crawler width extended to 1500 mm
(59.1 in.) to maximize the machine
stability. If the machine is operated with
the crawler width narrowed (1100 mm,
43.3 in.), the machine may tip over due
to its poor stability.
• If the machine must be operated with
the narrowed crawler width (1100 mm,
43.3 in.), traveling should be done after
folding the hoe attachment, lowering the
boom to lower the center of gravity and
keeping the machine facing forward.
IMPORTANT: All debris, mud, soil, stones,
etc. must be removed from the track
frame before switching the crawler width.
Do it in a safe manner and do not work
under the machine.
This machine is able to change the crawler
width. Normally, it is best to operate with the
crawler width extended for machine’s
stability.
Switching the crawler width
Perform the operation on a flat and rigid
ground where no obstacles around.
2. Turn the crawler width switch lever in the
direction of “A” to increase the crawler
width (1500 mm or 59.1 in.).
If necessary, extend the blade width by
changing the plate (2).
Refer to “Switching the blade width” on
page 3-11.
OPERATING THE MACHINE
1. Raise the machine body by using the hoe
attachment and the dozer blade.
IMPORTANT: Be sure to raise the machine
body before switching the crawler width.
If the operation is attempted when the
crawler is rested on the ground, the travel
frame or span cylinder may be damaged.
