• INTRODUCTION
This chapter describes all the general maintenance operations to be performed on the machine based on its actual operating
conditions, without following any particular schedule.
WARNING! Carefully read the instructions in chapter ORDINARY MAINTENANCE before carrying out the
following operations.
• ADJUSTMENT OF THE BOOM PADS AND/OR CARRIAGE PARALLEL INCLINATION
(only for P37.12 PLUS – P38.12 PLUS – P38.13 PLUS – P38.14 PLUS – P40.17 PLUS – P38.12 – P38.13 – P38.14 – P40.17
– P38.13EE – P40.17EE)
Should clearance between boom sections and sliding pads result excessive
and/or carriage is not parallel to the ground it is necessary to extend the boom by
approx. 30 cm. and proceed as follows:
- remove the protective casing "P"
To adjust horizontal clearance:
- loosen the side lock nuts (A)
- tighten dowels (A) fully, in the same way on both sides to centre the boom
- loosen the dowels by 1/2 a turn to give the necessary clearance and
tighten the lock nuts.
To adjust vertical clearance:
- loosen the lower lock nuts (B)
- tighten the lower dowels (B) fully then loosen them by 1 turn to give the necessary clearance and tighten the lock nuts.

correctly parallel to the ground, the sliding shoes of the boom need to be
adjusted as follows:
