4. INSTRUCTION FOR USE
4.1 PRESCRIPTIONS FOR THE OPERATOR
PROHIBITION: it is forbidden to walk or stop in front or backward the machine and/or under
the towing rope due to a constant residual risk of crushing in case of a possible giving in of the
rope or of the anchoring.
Daily, before starting the work, check:
a. if the protection and safety devices are activated and functioning
b. if the connections with power unit are in good conditions
c. if the machine liquids levels are in conformity with the indications in maintenance chapter
d. if the anchoring conditions are in conformity with the indications of present manual.
NOTE: when using the machine at room temperature between -10°C and -20°C it is
necessary to carry out the preheating sequence as indicated at paragraph 4.10 and
4.11.
4.2 CONTROLS
Position and meaning of the elements on the control board are described on table 3 enclosed.
4.3 PRELIMINARY OPERATIONS
a. Load the conductors or the cables on the bull-wheels as shown on tables 2 and 4 positioning the
entering guide-rope rollers in the proper position.
ATTENTION: do not use excessively lubricated or greased ropes because possible
adherence problems on the bull-wheels with a consequent sliding of the ropes
themselves may arise.
b. Lubricate the gears before each starting of the machine using the proper greasers (table 2, pos. 2).
c. Position the lever of mechanical transmission (table 2, pos. 9) into the proper ratio in accordance
with the job to do:

pos. C: high pull (tension higher than 4kN) (normal braking)

pos. B: low pull (tension lower than 4kN) (fine braking)
NOTE: the stringing speed can be read on the manometer scale relevant to the selected
reduction ratio.
ATTENTION: this operation must be made only with stopped machine and without
applied loads.
PROHIBITION: when you position the mechanical transmission control lever on the low
pull (table 2, pos. 9B) on the panel switch on the red light (table 3, pos. 23), which
advise that the machine cannot absolutely be used as puller but only as tensioner.
DANGER: please pay attention to the risk to be squeezed during the operations above
described.
