ATTENTION:

https://harrissupplyind.com - To Order Parts Call 608-268-8080

Never charge a GEL battery with a non suitable recharger. Strictly follow the instructions supplied by the batteries and recharger manufacturer.

In order not to cause permanent damages to the batteries, it is necessary to avoid their complete discharge, providing for the recharging within a few minutes after the batteries discharge signal starts blinking. NOTE: Never leave batteries completely discharged even if the machine is not used. In case of traditional batteries, please check the electrolyte level every 20 recharging cycles and eventually top them up with distilled water.

ATTENTION:

For the recharge of the batteries it is necessary to follow strictly all the indications given by the manufacturer/distributor. All the installation and maintenance operations must be carried out

by qualied staff. Danger of gas exhalations and emission of corrosive liquids. Fire danger: do not approach with

free ames.

BATTERIES DISPOSAL It is compulsory to hand over

exhausted batteries, classied

as dangerous waste, to an authorized institution according to the current laws. BATTERIES CHARGE LEVEL INDICATOR TURNING THE KEY (9) CLOCKWISE, ON THE DISPLAY (1) APPEAR IN SEQUENCE THE FOLLOWING INFORMATION:

1. The version (for example A003) of software installed on the machine.

2. The setting of the battery check card is for the 24V version: GE 24: check card set for GEL batteries Pb 24: check card set for lead batteries

3. The batteries charge level indicator (1) is digital. The battery charge level starts at 90, which indicates the 90% of the total charge and decreases by 10 to 10. When the charge level reaches 20%, the display starts blinking, so you are about at the end of working time.

ATTENTION:

After a few seconds from the blinking of the four lines, the brushes motor stops automatically. With the remaining charge

it is anyhow possible to nish

the drying operation before proceeding to the recharge area.

HOUR METER The machine is equipped with an hour meter located on the same display of the battery charge level indicator (1). Keeping the button (8) pressed for

more than 3 seconds, the rst

data indicates the working hours and after a few seconds the working minutes are shown.

SQUEEGEE ASSEMBLY

1. Maintain the squeegee support (1) slightly lifted from the

oor.

2. Insert the two stud bolts (3) placed on the upper part of the squeegee (2) inside the slots on the support.

3. Block the squeegee by rotating the lever (4) clockwise.

4. Insert the squeegee hose (5) into its coupling, respecting its position as indicated in the

gure.

Page 13

ADJUSTMENT OF THE

https://harrissupplyind.com - To Order Parts Call 608-268-8080

SQUEEGEE In order to have a perfect drying result through the squeegee, the rear rubber must have the lower bending uniformly adjusted in all its length. For the adjustment, it is necessary to put oneself in working condition and therefore the suction motor has to be switched on and the brushes have to function together with the detergent solution.

Height adjustment Once that the pressure and inclination of the squeegee has been adjusted, it is necessary to x this optimum condition making touch slightly the wheels onto the oor. Rotate counterclockwise the registers (8) to lower the wheels or clockwise to raise them. Both wheels must be adjusted in the same measure.

Block the coupling levers (2) in the rear part of the brushes base group to the rings placed at the extremity of the metal strips still free. Please act as above for both splash guard rubbers, paying attention to reduce to the minimum the gap between the two rubbers in the front part of the brushes base group. With brushes assembled, the splash guard must slightly touch

the oor.

The lower part of the rubber is too much bent Take off the pressure rotating the wing nut (6) counterclockwise. The lower part of the rubber is not much bent Increase the pressure rotating the wing nut (6) clockwise.

The bending is not uniform Adjust the squeegee inclination rotating counter-clockwise the wing nut (7) to increase the bending in the central part, or clockwise to increase the bending on the extremities.

ATTENTION:

Every type of oor requires a specic adjustment. For example, concrete oors (where the

friction results to be high) need little pressure, while smooth

oors (ceramics) need higher

pressure. If the cleaning operations are made always on the same type

of oor, the adjustment can

change only in function of the rubber wear. SPLASH GUARD ASSEMBLY The two splash guards have to be assembled onto the brushes base group. Insert the metal strips inside the suitable slots present on the rubber. Place the

round hole at the at extremity

of the strip onto the screw (1) placed in the front part of the brushes base group. Secure the strips through the nut blocking it.

BRUSHES ASSEMBLY The machines which have the electrical brushes base lifting:

1. Switch on the machine by turning the key (9) clockwise.

2. Press the push button (7) of up/down brushes base to lift the brushes.

3. Take off the electric supply by turning the key (9) counterclockwise.

ATTENTION:

To carry out brushes assembly operations with the electric supply on, may cause damages to hands.

Page 14

With the brushes base group in

https://harrissupplyind.com - To Order Parts Call 608-268-8080

lifted position, insert the brushes into their plate seat underneath the brushes base turning them until the three metal buttons are properly seated in their slots; quickly rotate the brushes to push the button towards the coupling spring until they get blocked.

The gure shows the rotating

sense for brushes coupling.

For a longer life of the brushes we suggest to invert daily their position. Whenever brushes are deformed we suggest to reassemble them in the same position, avoiding that the different inclination of the bristles causes excessive motor overload or troublesome vibrations.

FLOOR CLEANING CONNECTION OF THE BATTERIES TO THE MACHINE Once that the battery recharging has been completed:

1. Disconnect the connector (3) of the battery recharger (1). To do this, it is necessary to reach the battery compartment as indicated under paragraph “ACCESS TO THE BATTERY COMPARTMENT”.

2. Connect instead the machine connector (2).

3. Close the battery compartment.

RECOVERY TANK Check that the cover of the suction lter (1) is correctly secured, after rotating the levers (2) and that the suction motor hose (3) is correctly connected to it. Verify also that the squeegee hose couplings (4) are correctly inserted into the seats, that the exhaust hose plug (5) placed in the front part of the machine is closed and the inspection cap (6) is closed well.

DETERGENT SOLUTION TANK The capacity of the detergent solution tank is indicated in the technical data. Open the screw plug placed in the rear left part of the ma-

chine and ll the solution tank

with clean water at a maximum temperature of 122°F (50°C). Add the liquid detergent in the percentage and conditions foreseen by the manufacturer. To avoid excessive foam presence, which could cause problems to the suction motor, use the minimum percentage of detergent. Screw down the plug to close the tank.

ATTENTION:

Use only brushes supplied with the machine or the ones indicated in the paragraph “RECOMMENDED BRUSHES”. The use of other brushes can compromise security.

Always use low foam detergent. To avoid foam presence, before starting working operation, introduce into the recovery tank a minimum quantity of anti-foam product. Never use pure acid.

3S “SOLUTION SAVING SYS-

https://harrissupplyind.com - To Order Parts Call 608-268-8080

TEM” (OPTIONAL) The need of an increasing carefulness to the environment, and to the abuse of polluting elements, such as detergents

in the oor cleaning machines,

has brought us to the realization of a device which, regardless from the capacity to use the machine by the operator,

keeps the minimum ow of the

detergent solution constant, having been properly calibrated by an expert technician. The best detergent solution amount with this system will be the one

which realizes the minimum ow of detergent solution sufcient to clean correctly the oor. For

this reason the system is called “Solution Saving System” abbreviated to “3S”. The system is composed of a hydraulic circuit parallel to the traditional one which can be enabled or disabled directly from the instrument board through a 3-position switch with the following functions: (1) = Position solution valve with traditional functioning with

variable water ow that differs

by the opening of the solution valve. (2) = Position STOP No solution

ow (drying only).

(3) = Position 3S with function-

ing with optimal xed ow.

STARTING OF THE MACHINE

1. Turn the key (9) clockwise.

2. Check the battery type and the charge level on the display (1).

3. Press the brushes motor switch (6).

4. Press the suction motor switch (3).

5. Press the solenoid valve switch (5).

6. Lower the brushes base onto

the oor.

The machines which have the electrical brushes base lifting press the push button (7) of up/ down of the brushes base.

7. Acting upon the solution valve lever (14) open and adjust the

detergent solution ow. The water starts to ow auto-

matically acting upon the levers drive control (12). On the instrument board the indicator of the solenoid valve switch (5) will turn on. Releasing these levers,

will stop the ow.

Models equipped with the 3S, (optional), it is necessary to press the suitable switch to activate the detergent solution supply by choosing between the traditional adjustment system through the solution valve or the system of xed optimum supply (see under “3S SOLUTION SAVING SYSTEM”).

8. Acting upon the squeegee lifting lever (17) lower the squeegee.

9. Acting upon the levers drive control (12) the machine starts to move, the brushes start to rotate and the squeegee starts to dry.

10. During the rst metres

check that the squeegee adjustment guarantees a perfect drying action and that the deter-

gent solution ow is appropriate. It has to be sufcient to wet the oor uniformly avoiding the

leakage of detergent from the splash guards. Always consider that the correct quantity of solution detergent depends on type

of oor, dirtiness and machine

speed.

FORWARD MOVEMENT The traction of the machine is given through an electronically controlled motor. To move the machine, act upon the key (9) and then rotate the levers drive control (12) placed on the handle bar, in forward you obtain the forward drive, in reverse the backwards movement is obtained. The control acts in a progressive way, therefore it is possible to graduate the speed depending on each requirement rotating the lever whatever it is necessary. During reverse motion the speed is reduced.

SPEED ADJUSTMENT Two values of the maximum drive working speed in forward movement can be chosen. Set the wanted speed through the speed selection switch (2).

Page 16

ATTENTION:

https://harrissupplyind.com - To Order Parts Call 608-268-8080

SECURITY DEVICE REVERSE MOVEMENT A large sized push button (13), placed on the rear of the machine is for the automatic drive inversion. If the operator unintentionally remains blocked between the machine and an obstacle, this push button gives the control to invert the machine when it touches the operator.

WORKING BRAKE To stop the machine during normal working situation, it is suf-

cient to release the levers drive

control (12), as the machine is equipped with an electronic braking system. The brushes

and the detergent solution ow

stop automatically. EMERGENCY BRAKE In case of an emergency, an immediate stop can be obtained acting upon the lever of the emergency and parking brake (16) by pushing it downwards.

ATTENTION:

This control blocks the machine immediately. The emergency brake functions also as a parking brake. To start again to work, release the lever by unblocking the parking button on the lever itself and act again upon the levers drive control (12). ADJUSTMENT OF THE BRUSHES PRESSURE Through the register (1) it is possible to adjust the brushes pressure on the cleaned surface. By turning the knob clockwise the pressure increases, rotating it counterclockwise, the pressure decreases. This device allows a more ef-

cient cleaning action on very difcult and dirty surfaces.

Material CHARACTERISTICS

PPL (Polypropylene) Good wear resistance. Maintains characteristics with hot water up to 140°F (60°C). It is

not hygroscopic.

NYLON Excellent wear resistance, even with hot water over 140°F (60°C). It is hygroscopic. It

looses its physical characteristics over time.

TYNEX Nylon bristles with grains of abrasive material. Use with caution in order not to mark the

oor or ruin the polish.

BRISTLE THICKNESS Thicker bristles are more rigid and must be used on smooth oor or oor with small joints.

On irregular oors with deep joints or relieves, it is recommended to use softer bristles

which penetrate more easily and deeper. Please be aware that when brush bristles are worn out and therefore too small they become rigid and unable to penetrate and clean deeper. This may also happen with thicker bristles creating brush vibration.

PAD HOLDER It is equipped with anchor points which permit the blocking of the abrasive pad during

work. The pad holder is recommended to clean smooth oors.
