PRECAUTIONS WHEN USING HYDRAULIC CYLINDERS AT
THE END OF STROKE
When the hydraulic cylinders are activated, be careful so as not
to reach the end of stroke; always leave a small margin.
If working tools are used with the cylinder rods at the end of
stroke and are subject to shocks due to external forces, the hy-
draulic cylinders may get damaged, and injuries may be
caused. Avoid performing operations in which the hydraulic cyl-
inders are extended or retracted completely.
q
EXCAVATION ON HARD ROCKY GROUND
It is advisable to carry out excavations on hard rocky ground af-
ter breaking it up with some other means, in order to avoid dam-
aging the machine and to ensure a more economic use of the
same.
