• Before operating the travel levers or travel pedals,
check the direction of the track frame.
If the track frame is facing the rear (if the sprocket is at
the front), the machine moves in the opposite direction
to the direction of the operation of the travel levers or
travel pedals (front and rear travel are reversed, right
and left steering are reversed).
• Check that the area around the machine is safe, sound
the horn before starting the machine.
• Prohibit anyone other than the operator from coming
close to the machine during operation.
• Clear any obstacles from the travel path.
• There is a blind spot at the rear of the machine, so be
particularly careful when traveling in reverse.
• If the travel levers or travel pedals are operated when
the engine speed is decreased by the auto-decelera-
tion function, the engine speed will suddenly increase.
Operate the levers carefully.
• When traveling, check that the alarm sounds normally.
