OF THE BOOM SECTIONS
Any boom section is fitted with adjustable pads located
on the four sides of the profile. These pads are secured
to both fixed and mobile part of every section.
All pads can be adjusted by the special shims.
Adjusting the pads:
- Remove or loosen the screws fixing the pads in relation
to type of shims used (with or without slots).
- Fit the necessary amount of shims.
- If the residual thickness of the pad is insufficient or
near the maximum wearing limit, renew the pad.
- Tighten the screws fixing the pads at the recom-
mended torque (see below). Use a dynamometric
wrench.

the screw diameter

Tightening torques higher than those recommended
can cause the break of the pad or of the locking
threaded bush.
CAUTION
Pads must compulsorily be replaced if the residual
thickness of the plastic layer with respect to the iron
bush fixing the block is equal or inferior to 1 mm.
