3. Entangling or dragging in the accessible rotating units. It is not technologically possible to
foreseen covering in correspondence of some rotating units (i.e. winding of the rope or of the
conductor on the bull-wheels and on the driving gears), due to an excessive restriction of the
machine functionality and operative functions.
To reduce to min., the risks the operator has to:

avoid any possible contact with the machine rotating units except for the control devices

respect the prescriptions indicated in the present manual concerning wearing and the necessary
safety devices.
4. Limbs crushing during loading or removal of the rope-conductor. These operations have a
large risk margin due to the use of mechanical parts to be moved.
To reduce to min., the risks the operator has to:

know the directives for accident prevention and apply them.
5. Electrostatic discharges. The machine has not a proper grounding device for this reason, during
stringing operations, it is possible to have dangerous electrostatics discharges on ropes and
conductors.
To reduce to min., the risks the operator has to:

know the directives for accident prevention and apply them

check if the job site has a suitable grounding device for the machine-rope-
conductor’s system.
6. Inhalation of the endothermic engine exhausting gas. The machine discharge exhausting gas
of the endothermic engine combustion.
To reduce to min., the risks the operator has to:

respect the working positions indicated in the manual

respect the indications of Attention and Prohibition indicated in the present manual

if necessary, use safety devices for the respiratory tracts.
7. Control lever that can be blocked in working position. For functional reasons and comfort in
the use the control lever does not foreseen the return to zero when released; anyway the machine
is equipped with two security devices which prevent the creation of dangerous situations: electric
limiting device of the pull on the dynamometer, which stops the power station when the pre-set
value is reached, and load pre-setting device, which maintains the programmed pull automatically
adjusting the working speed.
To reduce to min., the risks the operator has to:

put the pull electric limiting device on a value just higher than the value obtained with the pull
adjusting valves (see par. 4.5)

operate the desired pull setting as described in the manual (see par. 4.5).
