OPERATION
MACHINE OPERATIONS AND CONTROLS
3-157
Long-Time Continuous Travel Operations
Do not travel continuously at high speed for two hours or more.
The lubricating oil inside the track rollers will rise to a high tem-
perature, and there is danger that this will cause damage to the
oil seal or leakage of oil.
When traveling continuously for a long time, stop the machine
for 15 minutes every 2 hours to allow the lubricating oil inside
the track rollers to cool down.
GENERAL OPERATION INFORMATION 3
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.
