upper part of the squeegee, inside the slots on the support. Block the squeegee by rotating the lever (2) clockwise. Insert the squeegee hose (3) into its coupling,

respecting its position as indicated in the gure.

ADJUSTMENT OF THE 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.

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 (2) pressed

for more than 3 seconds, the rst data indicates

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

The lower part of the rubber is too much bent Take off the pressure rotating the wing nut (4) counterclockwise. The lower part of the rubber is not much bent Increase the pressure rotating the wing nut (4) clockwise.

Page 15

The bending is not uniform

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

Adjust the squeegee inclination rotating counterclockwise the wing nut (5) to increase the bending in the central part, or clockwise to increase the bending on the extremities. 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 counterclock-

wise the registers (6) to lower the wheels or clockwise to raise them. Both wheels must be adjusted in the same measure. A label placed near the two registers (6) indicates rotation sense to increase or reduce the height.

To assemble the pad proceed as follows: Move the pedal (13) to lift the base. Position the pad under the base and then lower it always through the lever (13).

FLOOR CLEANING CONNECTION OF THE BATTERIES TO THE MACHINE

the levers drive control (9). On the instrument board the indicator of the solenoid valve switch

(4) will turn on. Releasing these levers, the ow

will stop.

Page 17

8. Acting upon the squeegee lifting lever (12)

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

lower the squeegee.

9. Acting upon the levers drive control (9) the machine starts to move, the base starts to vibrate and the squeegee starts to dry.

10. During the rst stretches check that the

squeegee adjustment guarantees a perfect dry-

ing action and that the detergent solution ow is appropriate. It has to be sufcient to wet the oor

uniformly. Always consider that the correct quan-

tity of solution detergent depends on type of oor,

dirtiness and machine speed.

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 (14).

WORKING BRAKE

To stop the machine during normal working situ-

ation, it is sufcient to release the levers drive

control, as the machine is equipped with an electronic braking system. The base and the deter-

gent solution ow stop automatically.

FORWARD MOVEMENT

The traction of the machine is given through an electronically controlled motor. To move the machine, switch on the key and then rotate the levers drive control 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.

EMERGENCY BRAKE

In case of an emergency, an immediate stop can be obtained acting upon the lever of the emergency and parking brake (10) by pushing it downwards.

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.
