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).
