D-3.14 ADJUSTING THE SLIDING PADS 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 supplied
by GENIE upon demand.
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
recommended torque (see below). Use a
dynamometric wrench.
Tightening torques of the pad screws in relation to
the screw diameter
Screws M10 Nm 30
Screws M14 Nm 50
Tightening torques higher than those recommended
can cause the break of the pad or of the locking
threaded bush.
ATTENTION
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.
Minimum 1 mm
