MACHINE OPERATIONS AND CONTROLS
OPERATION
3-168
Swinging or Traveling When Rock Is on Top of Track Assembly
Do not swing the upper structure or travel if there is in the rock
on top of the track assembly. It will contact the undercover or
frame and cause damage. In the worst case, it may cause
damage to the hydraulic equipment and result in a serious
breakdown.
During operations, always check that there is no rock, pieces of
rock, or mud on top of the track assembly.
Sudden Lever or Pedal Shifting High Speed Travel
(1) Do not operate the levers and pedals suddenly or take any
other action to move the machine quickly.
(2) Do not operate the levers or pedals suddenly from FOR-
WARD (A) to REVERSE (B) (or from REVERSE (B) to FOR-
WARD (A)).
(3) Do not operate the levers or pedals suddenly (do not
release them suddenly) to stop the machine when traveling at
high speed.
High-Speed Travel Operations on Rough Ground
Do not travel at high speed on rough ground or rocks. Each
time the machine travels over rough parts of the ground sur-
face, the thrusting load on the machine will increase and
reduce the service life of the machine.
To protect the machine when traveling on rough ground or on
rocks, there is a cushion structure in the idler (1), so set the
idler facing in the direction of travel and travel at low speed.
