PRECAUTIONS FOR OPERATION
PRECAUTIONS FOR TRAVELING
Traveling over boulders, tree stumps, or other obstacles will
cause a big shock to the chassis (and in particular to the under-
carriage), and this will cause damage to the machine. For this
reason, always remove any obstacles or drive the machine
around them, or take other steps to avoid traveling over such
obstacles as far as possible.
If there is no way to avoid traveling over an obstacle, reduce
the travel speed, keep the work equipment close to the ground,
and try to drive the machine so that the center of the track
passes over the obstacle.
PRECAUTIONS FOR HIGH SPEED TRAVEL
On uneven roadbeds such as rock beds or uneven roads with large rocks, drive the machine with travel mode at
Lo.
When driving the machine with travel mode at Hi, set the idler
in the forward direction.
PRECAUTIONS FOR FOLDING WORK EQUIPMENT
When folding in the work equipment to the travel or transporta-
tion posture, be careful not to let the bucket hit the blade.
PRECAUTIONS FOR HITTING BLADE AGAINST OBJECTS DURING OPERATING
BLADE
Be careful not to hit the blade against rocks or boulders. This
will cause premature damage to the blade or cylinders.
