• Cut the top portion of the design surface (approximately 50 mm) left in rough dozing in one pass.
(Reduce the subsidence by completing the finish work in one pass.)
Adjust the offset amount, after checking the subsidence state.
• Reduce the dozing quantity in the finish work.
(Reduce the factors of ground subsidence.)
Set the dozing quantity to below the half of the blade height as standard.
RECOMMENDED APPLICATIONS AND MODES
METHOD FOR DOZING
Dozing work is the operation to cut the ground and make the lower surface than the current ground.
There are 2 methods as follows. Select the method of operation depending on the state.
METHOD FOR SCRAPING LEVELLY
This is the method to cut the ground in shallow depth for long distance to make the traveling in reverse more
comfortable.
Enable “Smooth Start” and select “Cutting & Carry”.
1.
Start the blade automatic control at position (A) apart from piling position (U).
The machine automatically start the dozing.
2.
After carrying the soil to piling point (B), drive the machine in reverse.
(T) Design surface
• If some place higher than the design surface is left at 1 time dozing, travel on that place several times so
that such place can be built as designed.
• If the soil in front of the blade disappears and no load to the blade in the middle of carrying the soil, drive
the machine in reverse once and get the load to the blade again.
• When the design surface is deep, offset the design surface upward and cut the ground by each 100 to
200 mm in steps, you can operate smoother and more stable.
