8.6.5 Adjustment of the lateral clearings
* Remove the locking screw (1) of the lateral sliding block.
* Turn the bracket of the sliding block (2) clockwise equally from either side of the boom until the
gap is eliminated.
* If the gap is not eliminated by turning the bracket the sliding block (3) has worn out and has to be
replaced.
* Open the bracket (2) to the extent that the locking screw (1) goes to the previous slot and lock it
with the nut (4).
8.6.6 Adjustment of the vertical gap (one and two - extension models)
* Open the fastening screws (5).
* Increase the shim (7) between the fastener (6) of the sliding block and top surface the boom as
required (thickness: 1 or 2 mm).
* The adjustment range runs out when the sliding blocks of the underside (8) are worn almost to
the level of lock pieces (9) level, when the sliding blocks are replaced.
If the slide blocks are adjusted to be fully gapless, their wear ac-
celerates and the movement of the extensions may be obstructed.
