SAFETY

How to prevent accidents.

No accident prevention programme is effective without the complete co-operation of the person directly responsible for operating the
machine.
Most of the accidents that may occur in a company, on the job or during transfers are caused by the non-observance of the fundamental
safety rules.
A careful and cautious user is the best guarantee against accidents and is more effective than any type of prevention programme.

FURTHER PERFORMANCES OF THE
MACHINE WITH ECO VERSION

The machine equipped with the eco version is
able to work with full performance even if the
eco version 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.

56041475

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 in this condition, it is
necessary to proceed with the recharge of the
battery or to start the eco version.

2- Protection against the excessive recharge. If
the battery voltage will reach the value of
about 29 Volt the automatic stop of the eco
version will occur.; in any case the machine
will still be able to operate only with
batteries. The eco version can be restarted
when the battery voltage will be low enough

SUMMARY OF MAINTENANCE CONTROLS
(battery version)

Warning: the following interventions must be

done with machine in Off condition
and master key out. All the periodic
maintenance operations must be
performed by skilled personnel or
by an authorized service centre.

Note: the battery life will depend on a good

periodic maintenance (check of the
level of the electrolyte and of battery
voltage). Besides it must be taken into
account that an unused battery is
submitted to a self-discharge
phenomenon. In the event that the
machine is not used for a long time (e.g.
3 or 4 weeks) it is necessary TO
RECHARGE THE BATTERY; infact the
battery voltage MUST NEVER drop
down below 20 Volt.
