12. OPERATION ADJUSTING BRACE ¤ WARNING If maintenance is carried out with the engine running, always have one worker sitting in the operator‘s seat while another worker carries out the maintenance. Both workers must mutu- ally confirm the safety during the operation. Start the engine and use inching control to tilt to the left and right. Adjustment can be carried out easily by rotating the brace handle while raising and lowering. When extending the brace Set the blade at FLOAT and rotate the brace handle to adjust. REMARK When operated in this way, the blade is tilted, so the handle gradually becomes heavier.
When this happens, return the blade from the tilt position to the horizontal position and turn the handle again according to the procedure given above. SHIM ADJUSTMENT Adjust the thickness of shim so that the ball joint play (7 points) in the axial direction (shown by the arrow) does not exceed 1 mm (0.04 in). 1. Remove shim 1 and tighten bolts 2 to eliminate the ball joint play. 2. Measure clearance “A” and remove bolts 2 . 3. Install shim 1 having its thickness of “A” mm to “A + 1” mm (“A” in. to “A + 0.04” in) in place with bolts 2 . 4. Confirm that ball joint can move smoothly after tightening bolts. 2-67
