2.8.3 PERSONNEL
q
Any maintenance operation must be carried out exclusively by authorized and duly trained personnel; specific
and personal protection measures must be adopted when grinding, welding and when using sledges or heavy
hammers.
q
When assembling the equipment or cylinder connection pins, use wooden, plastic or in any case not excessively
hard tools to check the centering of the holes.
Do not use your fingers, since you run the risk of cutting them off.

The normal or special equipment that must be installed on
the machine or that have been removed must be stored in a
safe place and positioned in such a way as to prevent them
from falling down.
If they fall on someone, they may cause serious bodily harm.

When assembling or removing any equipment, make sure
that the ropes and the lifting hook are in good conditions and
properly dimensioned for the load to be lifted.

ways lower the work equipment to the ground or in any case
lower it as much as possible.
