HANDLING BLADE ACCUMULATOR
METHOD OF OPERATING BLADE ACCUMULATOR
1.
Lower the blade to the ground and stop the engine.
2. Turn the starting switch to ON position (electricity flows in the
electrical circuit), then turn the accumulator switch ON.
3.
Maintain the condition in Step 2, operate the left and right blade
lift levers to the front and rear, and bleed the remaining
pressure inside the accumulator and hydraulic circuit.
4.
Turn the accumulator switch OFF, then start the engine.
5. Maintain the condition in Step 4, and extend the left and right
blade lift cylinders approximately 50 mm (2.0 in). (When doing
this, retaining pressure is generated at the bottom of the blade
lift cylinders.)
6.
Turn the accumulator switch ON and start the accumulator.
The oil at the bottom end of the left and right blade lift cylinders
will flow into the accumulator, the left and right blade cylinders
will retract, and the front wheels will come into contact with the
ground.
REMARK
In the condition Step 6, the pressure is maintained at the bottom end of the blade lift cylinder so the blade pushes
at a certain pressure.
If operations are carried out in the condition in Step 6, the blade will be able to follow a rise or fall of approximately
50 mm (2.0 in) in the ground surface, so uniform accumulator operations can be carried out.
In actual fact, by operating the blade lift cylinder lever in a suitable way, work is carried out within a certain up-
down follow-up range with a small pushing pressure.
Once the accumulator is set, there is no need to operate the blade lift cylinder when starting operations. If the
operation is stopped and the switch is turned OFF, raise the blade and put the blade in contact with the ground
again, then turn the switch ON to make it possible to set the accumulator to the same setting.
