WARNING
When performing the maintenance with the engine running, one worker sits in the operator's seat and
another worker performs the maintenance and they must check the safety with each other.
1.
Start the engine and tilt to the right and left in the inching
mode.
2.
Turn and adjust brace handle (1).
When retracting the brace, you can easily adjust it by put-
ting it onto a block and turning the brace handle.
Since the blade is tilted in this operation, the handle be-
comes heavy gradually. In this case, return the blade from
the tilted state to the horizontal state, and then turn the
handle again by the above method.
METHOD FOR ADJUSTING SHIM
Adjust so that the axial play (in the directions of the arrows) in
the ball joints (3 places) is 1 mm or less.
1.
Remove shim (1) and tighten bolt (2).
Tighten until the play in the ball joint is eliminated.
2.
Measure clearance (A) and remove bolt (2).
3.
Adjust thickness of shim (1) to (A) +0 to 1 mm.
4.
Tighten bolt (2).
5.
Check that the ball moves smoothly while the bolt is tight-
ened.
