Always wear work leather gloves when replacing the wire rope.
[CHECKING BOOM TELESCOPING WIRE ROPE]
When the telescoping wire rope (1) shows a condition as shown in the figure below, adjust is as follows:
1. Keep the boom level and check whether the center of the telescoping wire rope (1) sags during the boom retracting operation.
When it sags, refer to the next section, "Adjustment of Boom Telescoping Wire Rope".
2. Check that 5mm clearance is formed between booms No.3 and No.4, clearance (a) shown at right, with the booms retracted in a horizontal position.
If check finds clearance of 5mm or more, perform proper adjustment according to “Adjustment of boom telescoping wire rope”.
