OPERATION
MACHINE OPERATIONS AND CONTROLS
Digging Hard Rocky Ground
Do not attempt to directly excavate hard rocky ground with the work equipment. It is better to excavate it after
breaking up by some other means. This will not only save the machine from damage but will make for better
economy.
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 FORWARD
(A) to REVERSE (B) (or from REVERSE (B) to FORWARD (A)).
(3) Do not operate the levers or pedals suddenly (do not release
them suddenly) to stop the machine when traveling at high
speed.
Support Blade on Both Sides
(Only machines with blade specification)
When using the blade as an outrigger, never suport the machine
with only one end of the blade.
GENERAL OPERATION INFORMATION
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.
