extreme left of the machine);
https://harrissupplyind.com - To Order Parts Call 608-268-8080
ENGLISH
- 11 -
• pour clean water and detergent in the right concentration into the solution tank (fig. 2, N°. 23)
leaving a gap of at least 5 cm between the surface of the liquid and the tank inlet;
• refit the tank cover (fig. 2, N°. 2).
5.10 Work
Once you have prepared the machine with the mains cable connected to the power socket (or
with the batteries charged and the battery wiring connector (fig. 3, N°. 34) connected to the
cleaner (fig. 3, N°. 36)), with the detergent solut ion tank (fig. 2, N°. 23) full and with the brush
fitted:
• set the brush switch (fig. 2, N°. 7) to position I;
• set the suction motor switch (fig. 2, N°. 8) to position I: the suction unit will start up;
• push the squeegee lever forward (fig. 2, N°. 5): the squeegee will touch the floor;
• move the tap control slider (fig. 2, N°. 4) to the right: the tap will open, allowing the detergent
solution to flow to the brush;
• pull the brush control lever (fig. 2, N°. 11): th e brush (or pad drive) will rotate, washing the
floor and exerting a thrust that will move the machine forward;
• guide the machine over the floor to be washed;
• adjust the squeegee and the flow of detergent solution as required via the controls (fig. 4, N°.
45 and N°. 46; fig. 2, N°. 4);
• for the battery-operated version, monitor the battery charge control light (fig. 2, N°. 6) which
must always be on during work. When the light begins to blink, the batteries are low and you
must stop immediately to recharge them. Continuing to wash with the light blinking can lead
to permanent battery damage;
• monitor washing performance and replace the detergent solution when it has run out;
• do not stand still with the suction unit on and the detergent solution tap (fig. 2, N°. 4) open;
• every time you fill the detergent tank (fig. 2, N°. 23), always empty the recovery tank (fig. 2,
N°. 13).
Note: if the brush control lever (fig. 2, N°. 11) is ope rated intermittently for a prolonged period,
the brush motor may overheat consequently damaging the motor. In addition, in the mainsoperated version the motor needs 2-3 seconds' rest in order to start up again without straining.
You should therefore use the lever in this way only when necessary, for example when moving
round obstacles.
5.11 End of work
• Let the vacuum motor work for 2 minutes with the tank cover open to be sure the vacuum
motor itself is well dry;
• check that the tap control slider (fig. 2, N°. 4) is in the closed position (i.e. positioned at the
extreme left of the machine);
• remove the brush (or pad drive) to avoid permanent deformation;
• lift the squeegee from the ground (control fig. 2, N°. 5) to avoid continuous pressure
deforming the drying blades and therefore affecting performance;
• empty and clean the recovery tank;
• unplug, or recharge the batteries according to the model.
5.12 How to get the most out of your floor cleaner
When removing particularly stubborn dirt, washing and drying can be performed in two separate
stages:
https://harrissupplyind.com - To Order Parts Call 608-268-8080
ENGLISH
- 12 -
• prewashing: open the water tap and begin washing with the suction unit off and squeegee
raised, going over the dirtiest points several times. This gives the detergent time to act and
the brush time to perform efficiently;
• drying: lower the squeegee, start the suction unit motor and go over the same area again.
This ensures thorough washing and will considerably reduce subsequent routine cleaning.
For easy use and maximum efficiency, you are advised to work in straight lines as far as
possible, going over any areas that cannot be reached with the cleaner at the end, using a mop
or cloth.
6.
ORDINARY MAINTENANCE
6.1 General
To avoid damage to persons and the cleaner itself, always disconnect the power supply cable (in
the mains-operated model) or the battery connector before carrying out any maintenance
operations. The power supply cable of the battery charger, if incorporated, must also be
disconnected from the mains.
Maintenance operations on the electric plant and all operations not mentioned in the followings
must be done only by specialized persons.
6.2 Servicing and recharging the batteries (only battery-operated model)
To charge the lead batteries with liquid electrolyte, proceed as follows:
• move the cleaner to a well ventilated area (the batteries release inflammable vapours: before
opening the caps, always move to a well ventilated area away from fires, sparks, lit cigarettes
etc.);
• remove the bonnet (fig. 2, N°. 1);
• remove the battery caps and check that the electrolyte covers the plates; if not, top up with
distilled water;
• disconnect the battery wiring connector (fig. 3, N°. 34) from the one fixed to the cleaner
chassis and connect it to the battery charger socket. (Caution: DO NOT connect the battery
charger to the fixed connector on the cleaner chassis);
• recharge, regulating the battery charger according to the instructions;
• once the batteries are charged, check with a densimeter. If one or more elements are flat
according to the densimeter (whereas the adjacent elements are perfectly charged) it is a
sign that the battery is damaged and must therefore be replaced;
• close the caps again, reconnect the battery wiring to the machine and replace the bonnet.
If the machine requires gelatine batteries, follow the instructions below:
• remove the bonnet;
• disconnect the battery wiring connector from the one fixed to the cleaner chassis and
connect it to the battery charger socket. (Caution: DO NOT connect the battery charger to
the connector fixed to the cleaner chassis);
• only use a battery charger specifically designed for gelatine batteries; recharge, regulating it
according to the instructions;
• reconnect the battery wiring to the machine and replace the bonnet.
6.3 Cleaning the suction unit filter
• Remove the tank cover (fig. 2, N°. 2);
https://harrissupplyind.com - To Order Parts Call 608-268-8080
ENGLISH
- 13 -
• unscrew the knobs (fig. 3, N°. 42) and remove the filter box (fig. 3, N°. 41) and filter (fig. 3,
N°. 40);
• clean the filter under running water, leave to dry and refit everything.
6.4 Cleaning the detergent solution tap
To eliminate any scale that may prevent perfect closure of the tap, follow the instructions below:
• remove the tank cover (fig. 2, N°. 2) and complet ely empty the detergent solution tank (fig. 2,
N°. 23);
• slide your hand inside the detergent solution tank; grip the solution rod (fig. 3, N°. 26) and
pull up to disengage it from the tap body (fig. 3, N°. 30);
• pull out the solution filter (fig. 3, N°. 28) and clean it;
• clean the tap body (fig. 3, N°. 30) and shutter ( fig. 3, N°. 27) using a cloth soaked in
detergent;
• refit the filter;
• replace the shutter, pulling the solution rod up again.
6.5 General cleaning
When cleaning the machine, always bear the following in mind:
• avoid using hydrocleaners: water could seep into the electrical boxes or motors consequently
damaging them or causing a short circuit;
• do not use steam as the heat will deform the plastic parts (casings and tanks) and make the
nylon wheel bearings unserviceable;
• do not use solvents or hydrocarbons: you could damage the casings or rubber parts.
6.6 Replacing the squeegee blades
The job of the squeegee blades is to scrape the film of water and detergent from the floor thus
permitting perfect drying. With use, continuous friction will blunt and crack the sharp edge in
contact with the floor, affecting drying efficiency and thus requiring replacement of the blade.
Fig. 4

Each squeegee is fitted with two blades, only one of which will be subject to wear. Initially
therefore, when one blade is worn, simply swap them round and then when the second one is
worn, replace them both.
Swapping the blades (for references see fig. 4):
• remove the squeegee from its support (N°. 47), sl iding out the coupling (N°. 44) of the
suction pipe and loosening the two knobs (N°. 48);
• completely unscrew the two knobs (N°. 48) and dis connect the squeegee inlet (N°. 49) from
the squeegee profile (N°. 53); rotate the inlet by 180° with respect to the profile and refit on
the profile;
