21. Measure the height from the base point to the blade edge,
add this value to the elevation of the base point. Check
that the total value is equal to the elevation recognized by
the machine in the step 15.
CHECK BLADE ELEVATION
(SIGMADOZER)
(Straight tilt dozer)
1.
Set the base station and turn on the power supply.
2.
Turn on the power supply of the control box.
3.
Start the engine.
4.
Move the machine to a base point, the elevation of which is known.
5.
Perform the resetting of the stroke end of blade.
For details, see “RESET CYLINDER STROKE END (3-17)”.
6.
Make the tilted or angled blade straight.
7.
Raise the blade higher than the base point, approach the base point straight, and stop the machine.
8.
Set the joystick (steering, directional and gear shift lever) to NEUTRAL position.
REMARK
If you turn the machine (counter-rotation turn in particular), the directional error becomes large and the ac-
curate measurement cannot be obtained. When you turned the machine to correct the direction, drive the
machine in reverse once for approximately 5 m, and then drive straight forward.
9.
Lower the blade to match the either end of blade at right or
left side with the base point.
Stop the blade just before it touches to the ground and the
base point, and do not lower the blade to the ground.
REMARK
The setting place of the base point should be determined
in advance so that the machine is leveled with standard
posture.
The standard posture denotes that the blade edge is the
same height of the ground where the track contacts.
10. Check that “elevation control key” (1) and “slope control
key” (2) are green and the machine direction on the control
box screen is the same as the actual machine direction.
When “Heading Initializing” is displayed, retry from step 7.
Even if the machine is out of the design surface and “Out
of design area” is displayed, it is not a trouble.
