OPERATION
The current traction control operating state is displayed at the
traction level display of the machine monitor. For details of the
operating state, see the table.
You can select the maximum rim pull when the traction control
is turned on from "Auto", "Level 1" to "Level 5" with the traction
level selection function of the machine monitor.
For the selecting method of the traction level, see "TRACTION
LEVEL SELECTION (3-63)".
Position (C): S mode
S mode is actuated.
When the S mode is actuated, the S mode operation pilot lamp on the machine monitor lights up.
When the S mode is actuated, tires will not easily slip and operation on a very slippery ground such as a snow
removal work can be performed easily, because an appropriate driving force is obtained.
Moreover, the machine may start smoothly and a sudden start at forward travel may not occur.
REMARK
•
Select the traction level "Auto" for loading work. The rim pull is automatically adjusted to the optimum one to
reduce the fuel consumption and decrease the slipping of tires as well.
•
If you select the most suitable maximum rim pull for the work condition by using the traction control switch
and with the traction level selection function, you may increase the work efficiency and decrease the slip-
ping of tires.
•
If the rim pull is too large for the work condition, the boom may not easily be raised and tires may easily
slip. If tires frequently slip, the work efficiency may decrease and the service life of the tires is shortened.
•
If the rim pull is too small for the work condition, the bucket cannot be sufficiently pushed into the target
material of loading and the work efficiency may decrease.
