MACHINE OPERATIONS AND CONTROLS
When driving on rough ground (rock-bed, etc.), direct the idler
(1) having the cushion mechanism in the travel direction and
drive the machine at low speed.
GROUND WHOLE THE BOTTOM SIDE OF BLADE TO SUPPORT MACHINE
When using the blade as an outrigger, never support the ma-
chine with only one end of the blade.
DO NOT TRAVEL LONG -TIME CONTINUOUSLY
If the machine travels continuously at high speed for 1.5 hours
or more, the temperature of lubricating oil inside the track roll-
ers and final drive will rise up. This may cause breakage to the
oil seal or leakage of oil.
When driving the machine continuously for a long time, stop it
for 30 minutes every one and a half hours to cool the lubricat-
ing oil inside the track rollers and final drives.
If the machine travels continuously for a long time with the
tracks loosened, it may break the undercarriage parts.
When driving the machine for a long time, check the track ten-
sion every 1.5 hours and adjust any looseness.
For the adjustment, see MAINTENANCE, “METHOD FOR CHECKING TRACK TENSION (4-23)”.
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 at “Lo” speed.
When driving the machine at “Hi” speed, direct the idler forward.
