PREPARING THE MACHINE

Either in the petrol or in the DP version, the machine calls for a set
of 24 V batteries.
The machine can be supplied in three options:

1. Batteries supplied with the machine, tted and lled with acid,
ready for use.

2. Batteries supplied and tted dry (without the liquid electrolyte).

3. Batteries not supplied.

Raise the bonnet carrying the seat by pushing it forward towards the
steering wheel and check which option applies to your machine.

If the batteries are tted, open up one of the vent caps of each battery
and check if they are lled with electrolyte.

English (Translation of original instructions)

1 - If the batteries are already lled:

a) Check the level of electrolyte and top up if necessary (use only
distilled water).
b) Recharge (see the MAINTENANCE section and the battery
instruction handbook).

2 - If the batteries are supplied without liquid (i.e. dry), they must
be lled with sulphuric acid (density from 1.27 to 1.29 kg at 25°C),
according to the instructions given in the next paragraph and in the
battery handbook.

Filling batteries with acid.
Pay particular attention when you are handling sulphuric acid. This
substance is corrosive. If it comes into contact with your skin or eyes,
wash with plenty of fresh water and seek medical assistance.
Batteries must be lled in a ventilated area.

Fill the cells (or single elements) of the batteries with acid. The correct
level is indicated in the battery instruction handbooks.
After an hour, top up the cells, if necessary, with more acid.

Let the batteries rest – with the machine stopped – for another
hour and then rell, in accordance to the instructions given in the
handbook provided with the battery (refer to the “MAINTENANCE”
section). During the charging operations, all battery caps must be
open.

3- If the machine has been supplied without batteries, these must be
purchased and installed accordingly.
Competent battery specialists should preferably be contacted to
choose and install the new batteries.

The electrical connection cables supplied with the machine may be
used to connect the batteries.
Once the batteries have been installed, connect the battery connector
to the machine.

If the machine is in the DP version, it must be lled with lead-free
petrol , depending on the engine. A label indicating the kind of fuel
to use is in any case applied near the fuel cap.

Check the level of oil in the engine (see the “MAINTENANCE”
chapter).

USING THE MACHINE

TURNING ON THE MACHINE
Fit in the ignition key and turn it clockwise. Three zeros will come up on
the display for about three seconds, followed by the voltage rating of
the battery.
The operator’s seat features a safety device that disables traction (forward
and reverse) when the operator gets up from his seat.
NOTE: temporary activation of the indicator lights on the console and of
the horn is to be considered normal.

Let at least three seconds pass after you have turned o the machine,
before turning it on again.
Check the state of the batteries on the appropriate display.

The display has two functions: Voltmeter and Hour meter.

The voltmeter features an undervoltage checking function which
automatically disables all services, traction excluded, if the battery charge
level drops below 20.5V (“FLAT BATTERY” ashes on the display)
In this case, recharge the battery (see the “MAINTENANCE” section and
the battery handbook).
If the battery charge level is suitably high, you can start your work.
If the machine features a petrol engine, rst start the engine.

STARTING/STOPPING THE PETROL ENGINE

To start the endothermic engine, push toggle switch I towards
its START position (see switchboard); the toggle switch will ick
automatically back to its initial position.

N.B.: if the engine does not start immediately, the maximum activation
time of the starter motor must not exceed 5 seconds for a petrol
engine . These activation intervals can be repeated after a short
resting time (approximately 8 – 10 sec.).
To stop the motor, ick toggle switch I to OFF.

When the machine is running with the endothermic engine, make sure
the cooling fan is running too. If the alternator overheats, the overheating
protection device it is tted with will stop the machine with the “ENGINE
PAUSE” error code.

To switch the machine ON, select either forward or reverse on the button
on the steering wheel. Then press the accelerator pedal and the machine
will start moving.
AUTO-POWER-ON/OFF
An automatic system turns the machine functions on and off
automatically.
When one of the three work programmes is selected by pressing the P1,
P2 or P3 button, the following functions are temporarily activated: centre
brush, suction motor, side brushes. The LED of the chosen programme
and the centre brush LED come on at the same time.
If the accelerator pedal is not pressed, after a few seconds the functions
shut down and the three LEDS start ashing. The sweeper is now in AUTO­POWER-OFF mode. All functions are automatically reactivated when the
user presses the accelerator pedal: AUTO-POWER-ON.

NOTE: When the accelerator is released all the machine functions are
automatically switched off, with the exception of the endothermic
engine, which will be switched o after approximately 6 seconds (AUTO
POWER OFF).

USING THE WORK PROGRAMMES

After turning on the machine and starting the engine, if necessary,
choose among the three available programmes, the one best suiting
your requirements by pressing one of the three keys.

REMOVING THE BATTERIES

When removing the batteries, the operator must be equipped with suitable
personal protection devices (gloves, goggles, overalls, safety shoes, etc) to
reduce the risk of accidents.
Make sure the switches on the control panel are in the “0” position (o) and the
machine is turned o. Keep away from naked ames, do not short circuit the
battery poles, do not cause sparks and do not smoke. Proceed as follows.

• disconnect the battery wiring and bridge terminals from the battery poles.

• if necessary, remove the devices fixing the battery to the base of the
machine.

• lift the batteries from the compartment using suitable lifting equipment.

conditions

Lower the left and/or right side brush by pulling out and lowering
the relevant knob.

NOTE: the relevant left or right indicator light will come on.
To move the brushes back to their OFF position, pull up the knobs.

The speed of the side brushes can be changed using the adjustment
knob shown in the gure.

The machine features a red emergency stop button.
Press this button (the red warning light will come on) to bring all
machine functions, engine included, to an immediate stop. To restart
the machine, press the red button down and start up the functions
requested.

If you are using the machine on wet ground, it is essential to protect
the machine’s paper lters by turning o the aspirator motor with
the ON/OFF button.

FURTHER PERFORMANCES OF THE MACHINE FEATURING AN

ENGINE

The version featuring an engine can guarantee the same working
eciency even when the motor is o, for instance when the fuel has
run out or when working in closed environments.
The working autonomy, in this case, will depend on the capacity
(Amperes/hour) of the batteries installed, on the intensity of the work
programme chosen and on the battery charge status.
To guarantee the working life of the batteries, the machine features
some safety systems:

1- When the battery voltage drops below 20.5 Volt, all machine
functions, with the exception of the traction system, are automatically
stopped. When this situation occurs, recharge the batteries or turn
on the engine.

2- Protection against excessive battery charging
Being tted with a current generator featuring an electronic circuit,
that acts as voltage regulator, the machine can correctly charge the
battery without damaging it with an excessive charge.
In fact, when the battery has been properly charged, it will except
no further charging energy.

3- Using the machine with a battery or engine

Further to the tests effected and the results obtained from the
evaluation of the energy consumption of our hybrid system, we can
arm that Genius 1050 can work autonomously. In other words, the
machine does not have to be stopped to recharge the set of batteries
. Tests have been made with all three programmes at the user ’s
disposal, namely P1, P2 and P3, on asphalted surfaces and normal
slopes, and the sweeper has worked autonomously.
However, being the machine designed also for heavy duty working
conditions (slopes of over 16%, extremely rough surfaces to clean),
the batteries may need to be recharged.

In this case, we recommend the use of an intelligent batter y
charge with a IUIa charging curve and a nal proportional charge,
appropriately designed for this kind of machine and of a suitable size
for the battery installed.

After you have ended your work, disable the selected programme (1­2-3) and turn o the engine by icking the toggle switch ‘I’ to OFF.

Before leaving the machine, make sure that the side brushes are raised
from the oor, the parking brake is engaged and that the ignition key
has been take out of the instrument board.

CLEANING AND SERVICING THE FILTER

The lter is a very important component of the machine and essential
for correct operation.
Pro per filter maintenance will allow you to obtain the best
performance from your machine.
The lter can be cleaned in any of the following three ways:

1) by means of the automatic cleaning system
Accord ing to the chosen work progra mme, the machin e is
programmed to automatically clean the filter at regular preset

intervals.

2) by means of an electric lter shaker that is manually started

Just a simple command is needed to keep the lter in perfect
working order: press the button marked ‘F’ and hold it down for a few
seconds. Repeat this operation 4 or 5 times.
Remember that the cleaner the lter, the better the results of your
cleaning session. It is recommended to carry this operation
out at the end of each work cycle.

NOTE: dusty environments
If you are using the machine in a dusty environment (e.g. sawmills
– warehouses where haulage vehicles pass, etc.), it is a good idea to
use the lter shaker more frequently.

3) by manually cleaning the lter

If operating the lter shaker is not enough to keep the lter clean

- and in any case every 20 hours of work - clean the lter manually.
Before carrying out any kind of intervention on the machine, make
sure it is turned o and that all functions are deactivated. To obtain
this condition, turn the switch marked ‘L’ to OFF.

1° Remove the rear box from the machine

2° Take the lter out of its seat by turning the two xing handles.

3° Blow compressed air onto the side of the filter featuring the
protective net (at a pressure of 6 bar at the most).

4° Ret the lters and the rear panel.

FITTING AND REPLACING THE SIDE BRUSHES

NOTE: the engine oil must be replaced after the rst 20 hours of work
or in any case within a month.
It is then sucient to replace it every 100 hours of work or within 8
months.

To replace the oil in the engine, proceed as follows:

- Remove the right hand side casing of the machine by loosening
the xing screws.

- Gain access to the oil drainage pipe.

- Unscrew the dipstick.

- Take the cap o the drainage pipe and let the exhaust oil drain
out.

NOTE: oil should preferably be drained when the engine is hot.

Pour in new oil of the type and in the quantity indicated on the
use and maintenance manual of the engine. Use only SAE 15/49
multigrade oil which ensures eective lubrication at an ambient
temperature ranging from –15°C to over 40°C.

AIR FILTER OF THE ENGINE

Check the state of the engine’s air lter regularly.
If necessary, wash the sponge (pre-lter) with water and soap or a
standard household detergent.
Rinse and dry.
When necessary, replace the air lter of the engine.
Ret the lter and cover.

Drive board alarms

If the machine drive is interrupted, the error code should be identied by means of the status LED.
In the absence of malfunctions, the status LED is steadily on while the machine is in operation. If a malfunction is detected, the status LED
provides two types of information, a slow ash (2 Hz) or a rapid ash (4 Hz) to indicate the severity of the malfunction.
Malfunctions with a slow ash are cancelled automatically once the malfunction has been repaired and the machine functions normally
again.
Malfunctions with a rapid ash (“*” in the table) are considered more serious. The machine must be turned of to reset operation after repairing
the malfunction.
The indication of severity remains active for 10 seconds, after which the status LED ashes constantly showing a two digit malfunction code
until the repairs have been carried out.
For example, error code “1,4” is displayed as follows:

□ □ □ □ □ example alarm code 1,4
