FURTHER PERFORMANCES OF THE
MACHINE WITH GASOLINE ENGINE

The machine equipped with the gasoline engine is able
to work with full performance even if the gasoline
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.

56041481

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.
A different voltage cut-off value can be selected for
wet and gel batteries respectively.

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

MAINTENANCE

MAINTENANCE OF THE GASOLINE
ENGINE

First: read thoroughly the Use and Maintenance
Manual of the engine.
Here below some recommendations are pointed out.

Check the engine oil level twice per week. In order to
check the engine oil level the right side panel (grate)
must be removed, or simply slid up; save the five screws.
For possible fill up read the oil type specified in the
engine Manual.

To replace the engine oil first the right side wall of the
machine must be removed. In order to get access to the
five screws fixing the right side wall lift the hopper and
engage the hopper safety device: now you can get
access to the two rear screws. Lift the bonnet to get
access to the third screw. Open the right door of the
main brush compartment to access the forth and fifth
screws.

56041481

Warning: the engine oil must be replaced the first time
after 50 working hours; the succeeding times it must be
replaced every 100 hours.

NOTE: the engine is equipped with an oil safety device:
this device does not allow the engine start – or will
automatically stop the engine - in the event that the oil
level be too low. No monitor (LED) is provided for this
safety device.

Unscrew the oil level check rod and get access to the oil
empting hose.

Remove the cap from the engine oil emptying hose and
let the oil come out.

Note: it is suggested to remove the oil when the engine
is warm.

Dispose of the used oil in proper special containers.

Note: keep the emptying hose lifted and open during
filling.

Take a funnel and a rubber hose and pour in the new
oil from the hole of the rod for oil level check. Fit the
rod for oil level check and close the emptying hose with
its cap.

At the end of the filling sequence check the engine oil
level.

23

MAINTENANCE

Clean or replace the air filter according to the
instructions of the engine Manual or whenever it is
necessary.

In order to get access to the air filter the engine
assembly must be slid out; to slide out the engine
assembly first the right side wall of the machine must
be removed (see engine oil replacement procedure for
right side wall removal).

Then two screws must be loosened (17 mm wrench
required) to allow to slide out the engine plate/
assembly

56041481

Now the engine air filter can be reached (save two
screws).

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.
