GENERAL OPERATION INFORMATION

Traveling
Traveling over boulders, tree stumps, or other obstacles will cause
a big shock to the chassis (and in particular to the tracks), and this
will cause damage to the machine. For this reason, always remove
any obstacles or travel 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 travel so that the center of the track passes over the obstacle.
High Speed Travel
On uneven roadbeds such as rock beds or uneven roads with large
rocks, travel at Lo speed. When traveling at high speed, set the
idler in the forward direction.
Press travel speed selector switch (1) to switch the travel speed.
The travel speed (Lo, Mi, Hi) is displayed on the travel speed
monitor (2).
