OPERATION
MACHINE OPERATIONS AND CONTROLS
ACTIONS WHEN AUTOMATIC BLADE CONTROL IS ACTIVATED
While the blade automatic control is in operation, the blade au-
tomatically moves to lifting direction (A) and (C) and to tilting di-
rection (E) and (F) even if the blade control lever is kept in
NEUTRAL position.
Blade moves as such that the blade edge moves along the pre-
set design surface.
REMARK
When the design surface is located lower than the current
ground level, the blade will cut the soil.
When the design surface is located higher than the current
ground level, the blade will dump the soil holding in it to the
ground.
With these 2 operations, you can easily build a ground surface
as designed.
(In cutting mode or spreading mode)
When the load to blade increases, the blade is automatically raised to keep the constant targeted load by ad-
justing lifting amount, before the machine becomes impossible to travel forward.
(In cutting and carry mode)
See "OPERATION OF CUTTING AND CARRY MODE".
REMARK
If some places higher than the design surface are left, drive the machine in reverse, and drive it on that place
several times so that such places can be built as designed.
While the blade automatic control is in operation, if the operator operates blade control lever, the blade moves
as operated by the operator.
When the operator stops lever operation and return the lever to NEUTRAL position, the blade automatic control
restarts.
Operation of angle switch (1) is independent from the blade au-
tomatic control. While the blade automatic control is in opera-
tion, operator can angle the blade to change the dumping di-
rection of soil.
