IMPORTANT SAFETY
INSTRUCTIONS
This manual is a guide for use of the machine and
information concerning the functioning, regulation, and
ordinary maintenance of your new sweeper. Your ma-
chine has been designed and constructed to ensure
maximum performance in a large variety of conditions.
Before delivery, the machine was checked in our fac-
tory to ensure that it will be delivered to you in perfect
condition. To maintain the machine in these conditions
and guarantee functioning without problems, it is very
important that routine maintenance, specified in the
Maintenance section of this manual, be properly per-
formed. Before using the machine, carefully read this
manual and keep it within easy reach for further refer-
ence. Indications of “left” and “right” are referred to in
the direction of movement of the sweeper. If you should
need any further information concerning the sweeper,

Figure 1
Connect the batteries as shown; a 1/2 wrench or socket
will be needed. All necessary cable and hardware have
been provided. It is important that all connections made
to the battery are secure.
Periodically check the level of the electrolyte fluid in
each cell and top off when necessary. Add water to
1/4” above the plates. Avoid over filling the cells.
WARNING
When the battery voltage reading on the battery charge
level indicator is 19.0 or less, the batteries must be re-
charged immediately. If this is done, the long life of the
batteries will be ensured. Never use the machine when
only the first green LED is on.
BATTERY CHARGING
INSTRUCTIONS
Follow these instructions for charging the batteries:
1. Disconnect plug connecting batteries.
2. Maintain electrolyte fluid level in batteries.
Check fluid before charging. If needed, fill to 1/
4 inch above the plates, preferably with distilled
water.
3. Insert charging plug into battery receptacle. We
recommend using a battery charger (rectifier) of
the automatic charging control type. To make
this connection possible with any type of battery
charger, each machine is equipped with an
additional connector.
4. Plug power cord into proper AC source.
5. Keep battery cover open while charging.
6. Follow the directions on the charger.
WARNING
Hydrogen gas is formed during the charging opera-
tion and is explosive! Only charge batteries in a well
ventilated area with the lid open. Avoid any open flame
or electrical sparks. Pulling out the charger plug with
the charger on will cause an arc and must be avoided.
electrical parts of the machine dry. For storage,
keep the machine in a building.
ÿMake sure that all labels, decals, warnings,
cautions, and instructions are fastened to the
machine.
ÿDo not turn the steering wheel sharply when the
machine is in motion. The machine is very
responsive to movement of the steering wheel.
Do not make sudden turns.
ÿSweep in straight paths. Do not bump posts. Do
not scrape the sides of the machine.
ÿWhen the machine is in motion, do not reverse
the directional control switch. Switching direction
while in motion puts a very heavy strain on the
motor and drive system.
ÿAlways park on a level surface, turn key off, and
engage parking brake before working on the
machine to keep it from creeping or rolling.
ÿTo prevent damage to the machine and dis-
charges across the tops of the batteries, do not
fill the batteries above the bottom of the tube in
each cell. Wipe any acid from the machine or
the tops of the batteries. Do not add acid to a
battery after installation.
ÿBatteries are heavy. Get help to lift the batteries.
ÿTo prevent an explosion, disconnect the AC plug
from the receptacle before connecting or discon-
necting the DC plug on the charger.
BATTERY INSTALLATION
The machine has been shipped fully assembled and
needs only to have the batteries installed before opera-
tion can begin.
Remove the plastic battery box from the crated bat-
teries and install in machine. Place each of the two
batteries into the plastic battery box in an upright fash-
ion. This box will prevent any damage to the machine
should the battery’s case ever leak. Install each of the
batteries into the machine as illustrated in Figure 1.

GENERAL INFORMATION AND FUNCTIONAL NOTES
The display 1 incorporates two different instruments: a voltmeter and an hour meter.
Besides giving a reading on the battery level, the voltmeter also includes a device which automatically cuts off all
machine’s functions, except for drive, when battery level is under 19V.
At this point the batteries should be recharged. If this is done the long-life of the batteries is safeguarded (auto-
matic battery chargers should be used). We also recommend checking regularly the level of acid in battery and
topping up if necessary.
The hour meter function is selected by pushing button 4. The display shows first the hours and then the minutes.
After about 10 seconds the hour function is deactivated and the display will return to the battery level reading.
In case of electronic faults, the machine will stop and the display will indicate one of following error codes, each
one corresponding to a different type of fault:
302 = short circuit
306 = overheating of cooling vents
307 = incorrect sequence of key switch/accelerator pedal
308 = potentiometer wire broken
INSTRUMENTS AND CONTROLS

BATTERIES - PERIODIC MAINTENANCE
WARNING: All periodic and extraordinary maintenance must be carried out by competent personnel or by an
authorized Service Center:
NOTES:
The life of the batteries depends on how frequently periodic maintenance is carried out (check of level and
density of electrolyte) and on how much the battery is run down during work: the batteries must not be run down
under the level indicated (min. voltage 19.0) on the volt meter situated on the dashboard.
WARNING:
If used on hard floors:
Check electric motor’s carbon brushes every 200 hours of use.
If used on carpet:
Check electric motor’s carbon brushes every 125 hours of use.
The electric motor’s carbon brushes must be replaced every 500 work hours. A worn out brush is 3/8 in. long
or less.
