FURTHER PERFORMANCES OF THE
MACHINE WITH PETROL ENGINE
The machine equipped with the petrol engine is
able to work with full performance even if the
petrol engine is turned Off; this could occur just
because the machine run out of the fuel or when
it is necessary to work in a closed environment.
In this case the available working time will
depend on the capacity (amper.hours) of the
batteries installed on the machine; on the
intensity of the selected working program; on the
charge status of the batteries.
On this machine, in order to guarantee the
reliability of the batteries, two safety features are
envisaged:
1- protection against the deep discharge of the
battery: when the battery voltage drops down to
about 20 Volt the automatic stop of all function
will occur - except the traction function. When it
is in this condition, it is necessary to proceed with
the recharge of the battery or to start the petrol
engine.
2- Protection against the excessive recharge. If
the battery voltage will be over 29 Volt the
automatic stop of the petrol engine will occur.; in
any case the machine will still be able to operate
only with batteries. The petrol engine can be
restarted when the battery voltage will be low
enough (at about 24 Volt).
