MACHINE STRUCTURE AND CONTROLS - DESCRIPTION
Main switch for vacuum system, main broom and side broom activation (1) – When turned to “0” the machine is off; when
turned to “I” the vacuum system and main broom are turned on; when turned to “II”, the vacuum system, main broom and side
broom are turned on.
Green warning light (2) – When it is on and the machine is running, it indicates that the batteries are charged. Residual
autonomy depends on battery capacity and working conditions. When it is on and the batteries are charging, it means that the
charging cycle has been completed and the batteries are charged.
Yellow warning light (3) – When it is on and the machine is running, it indicates that the batteries are semi-discharged.
Residual autonomy is 10 minutes approximately. When it is on and the batteries are charging, it means that the charging cycle is
nearly completed and the batteries are nearly charged.
Red warning light (4) – When it is on and the machine is running, it indicates that the batteries are discharged. The autonomy
is over, the batteries must be recharged (see the procedure in the relevant paragraph). When it is on and the batteries are
charging, it means that the charging cycle is in progress.
Drive control lever (5) – When pulling it gradually towards the handlebar, the machine starts. Drive speed is increased by
pulling the lever further.
Handlebar (6) – Grasp it and use it to manoeuvre the machine.
Handlebar adjusting knobs (7) – Loosen the knobs and adjust the handlebar tilting, then tighten the knobs.
Filter shaker knob (8) – By moving it to right and then to the left several times, the fi lter is shaken; perform this procedure
periodically while sweeping in order to keep the vacuum system effi cient. Before turning on the fi lter shaker, stop the machine
and turn the main switch (1) to "0".
Hopper (9) – It collects swept and vacuumed debris. When it is full, it must be emptied according to the procedure shown in Use
chapter. When the hopper is removed, all machine functions are disabled.
Front steering wheel (10) – It allows the machine to steer.
Side broom (11) – It removes dust and debris on the machine front right end side (along footpaths, walls, etc.) and it conveys
them toward the main broom.
Side broom lifting/lowering lever (12) – Disengage it from the fastener, then push it forward to lower the side broom and pull it
backwards to lift it.
Side broom height adjusting knob (13) – It adjusts the side broom height from the ground (see the procedure in the
Maintenance chapter).
Main broom (14) – It removes and collects dust and debris, which are then vacuumed into the hopper.
Main broom height adjusting knobs (15) – They adjust the main broom height from the ground (see the procedure in the
Maintenance chapter).
Rear driving wheels (16) – They push the machine forward while sweeping.
Can holder (17) – Compartments to store a can or small objects.
Battery charger cable (18) – It is used to charge the batteries (see the procedure in the Maintenance chapter).
Battery charger cable housing (19) – Store the battery charger cable in this compartment when not in use.
Side broom motor circuit breaker (20) – It activates to protect the side broom motor in case of overload. If the circuit breaker
activates, wait for the motor to cool down, then reset the circuit breaker by pushing it inward, until the end-of-stroke.
30 A main motor circuit breaker (21) – It activates to protect the main motor in case of overload. If the circuit breaker
activates, wait for the motor to cool down, then reset the circuit breaker by pushing it inward, until the end-of-stroke.
Batteries (22) – They supply current for machine operation. The batteries are GEL type, without liquid electrolyte and do not
require maintenance.
Dust fi lter (23) – It retains swept and vacuumed dust and it allows the air to pass. While sweeping it is necessary to move the
fi lter shaker knob (8) periodically to remove the dust deposits on the fi lter, thus granting the vacuum system effi ciency.
Side broom motor (24) – It drives the side broom.
Main motor (25) – It drives the main broom and the drive system.
Drive system gear (26) – It supplies the drive force to the wheels.
Vacuum fan (27) – It vacuums dust and debris from the ground.
Battery charger (28) – It charges the batteries (see the procedure in the Maintenance chapter).
7.5 A vacuum system motor lamellar fuse (29) – It opens to protect the vacuum system motor in case of overload. If there is
an open, the fuse must be replaced by the authorised personnel.
Hood (30) – It protects the inner components of the machine.
Hopper handles (31) and (32) – These allow to grasp the hopper and handle it.
Serial number plate/technical data/conformity certifi cation (33) – It contains the machine data.
Side, front and rear skirts (34), (35), (36) – They increase the vacuuming effect for dust and debris collection.
