TIPS FOR LONGER UNDERCARRIAGE LIFE
Undercarriage life greatly varies depending on operation method, inspection and maintenance.
For most efficient operation, keep the following points in mind.
OPERATION METHOD
• Use a track shoe suitable for soil condition.
For selection of the shoe, consult your Komatsu distributor.
• Do not let the shoe slip during operation.
If the shoe starts slipping, decrease the load to prevent slipping.
• Avoid rapid start, acceleration, stop, or unnecessary high-speed operation or sharp turn.
• Travel as straight as possible. Do not turn only in either direction but turn in both directions evenly. Also,
secure turning radius as large as possible.
• Clear the travel ground and remove obstacles so that the machine does not ride over large boulders or ob-
stacles.
• On slopes, do not work across the slope surface but work
upward or downward. When stopping the machine on a
slope, direct it up or down.
• If the ground slants to the right or left while the machine is
digging, do not stay there but move back to a level place,
then start digging again.
• If the idler or sprocket floats because of a hard obstacle
during dozing or ripping work, avoid that obstacle, since it
is “difficult to move it”.
