PROHIBITION OF HIGH-SPEED TRAVEL OPERATIONS ON ROUGH GROUND
If the machine travels on rough ground (rock-bed, etc.) at high
speed, large push-up loads are applied to the chassis, thus the
service life of the chassis is shortened.
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, and oil seal may be damaged to
cause oil leakage.
Stop driving for 30 minutes every 1.5 hours to cool the lubricat-
ing oil inside the track rollers and final drives when driving the
machine continuously for a long time.
If the machine travels continuously for a long time with the
tracks loosened, the undercarriage parts may be broken pre-
maturely.
Check the track tension every 1.5 hours, and adjust any loose-
ness when driving the machine for a long time.
For the adjustment, see MAINTENANCE, “METHOD FOR CHECKING AND ADJUSTING STEEL SHOES AND
ROADLINERS TRACK TENSION” and “METHOD FOR CHECKING AND ADJUSTING RUBBER SHOES
TRACK TENSION”.
