TECHNICAL INFORMATION

General description

This machine is a scrubber dryer for sweeping, washing and drying at, horizontal, smooth or moderately rough, uniformly

structured and obstacle-free oors in civil and industrial premises. The scrubber dryer spreads a solution of water and detergent in

the correct concentration on the oor and then scrubs it to remove the dirt. By carefully choosing the detergent and brushes from

the wide range of accessories available, the machine can be adapted to a wide range of combinations of types of oor and dirt.

The machine incorporates a wet vacuuming system which dries the oor immediately after washing. The drying action is

produced by the suction motor, which generates a partial vacuum in the dirty water tank. Squeegees mounted beneath the tank

are designed to collect the lm of dirty water with the machine moving in both forward and reverse directions.

protection devices (gloves, goggles overalls, etc.) to limit the risk of injury. Keep clear of naked ames, avoid short circuiting the battery

poles, avoid sparks and do not smoke.

The Flooded Lead Acid Batteries batteries are normally supplied lled with acid and ready-for-use. If batteries without acid are to

be used, before mounting them on the machine, it is necessary to make them active as follows:

• After taking o the battery plugs, ll up all elements with a solution of specic sulphuric acid, until the cells are

thoroughly covered (ll each element at least twice);

• Let them rest for about 4-5 hours, to give time to air bubbles to come up to the surface and the plates to absorb the

electrolyte;

• Check that the electrolyte level is still above the plates, otherwise top up with the solution of sulphuric acid;

• Reclose the plugs;

• Install the storage batteries on the machine (following the procedure described below). It is now necessary to perform a

rst recharging before having the machine start; to do so stick to the instructions written in the respective paragraph.

Control Devices - Description

With reference to g. 8 the machine has the following controls and LEDs:

• Battery charge level indicator (ref. 9): signals both “Power on” and the battery charge level. Note: the following

percentages are based on the usable capacity and not the total capacity of the batteries (therefore 100% at = 80% of

total battery capacity). Possible situations are:

• O: the main switch is set to “0” (o) or the batteries are disconnected;

• Green light: batteries charged from 100% to 50%;

• Yellow light: batteries charged from 50% to 15%;

• Red light (also simultaneously with yellow or green light): batteries at and must be recharged.

• Main switch - emergency button with key (ref. 2): enables or disables the power supply to all the machine functions. It

acts as a safety device. To start the machine turn the proper key clockwise. To stop the machine press the button.

• Brush/roller up-down button (ref. 5): when the arrow down is pressed, the head moves down to the working position,

the brush motor comes on automatically and the solenoid valve is activated. Via this button, a variable pressure can

be exerted on the head during the work phase (according to how long the button is kept pressed), thus adapting the

cleaning power of the brushes to a wide range of dierent operating conditions. When the arrow up is pressed, the head

moves up to the rest position, the brush motors are switched o and the solenoid valve is de-activated.

• Brush pressure indicator (ref. 8): indicates connections of brushes and pressure exerted by the head (1 led on indicates

beginning of brush connection; 2 leds on indicate minimum pressure; 3 leds on indicate maximum pressure).

• Brush release button (ref. 4): permits release of the brushes; press the button for a couple of seconds: when the button is

released, the brushes will be released.

• Cock control lever (ref. 3): allows to adjust continuously the ow of solution sent to the brushes. On turning it forward, the

liquid outlet ow is increased.

• Drive command lever (ref. 6): placed under the handgrip, when it is slightly pressed upwards (the emergency button must

be active), it starts the drive motor thus making the machine move forward. When the lever is pressed down, the drive

motor moves the machine in reverse gear.

• Squeegee lifting lever (ref. 11): it allows to raise (when lifted) or lower (when pushed down) the squeegee. When it is

pressed down, the suction motor is also switched on for drying the oor.

• Hour meter (ref. 7 - optional): displays the hours of work of the brush.

• Parking brake pedal (ref. 12): engages (when pressed and moved to the right) and disengages (when pressed and moved

to the left) the parking brake.

• Potentiometer (ref. 1): permits adjustment of the machine forward and reverse speed; when the knob is turned clockwise

the speed is increased.

Installing And Adjusting The Squeegee

The oor wiper, also called squeegee (g. 2, ref. 8), is the rst responsible for drying. To

install the squeegee on the machine proceed as follows:

• Stop the machine and press the emergency button (g. 8, ref. 2); engage the

parking brake by means of the pedal (g. 9, ref. 5);

• Check that the squeegee supporting plate (g. 9, ref. 2) is raised, otherwise lift it

by acting on the proper lever (g. 9, ref. 6);

• Firmly push down the sleeve of the suction tube (g. 9, ref. 4) into the squeegee;

• Slacken the two knobs (g. 9, ref. 3) placed in the centre of the squeegee;

• Insert the two threaded dowels in the slots of the support (g. 9, ref. 2);

• Fix the squeegee by tightening the knobs (g. 9, ref. 3).

13Operations Manual Hurricane 700 XTT / Hurricane 850 XTT

The blades of the squeegee are used to scrub from the oor the lm of water and detergent thus allowing a perfect drying. As

long as time goes by the continuous scraping rounds o and splits the sharp edge in contact with the oor, thus reducing the

drying ecacy and therefore requiring the replacement of the blades. Therefore, often check their state of wear and tear.

To obtain a perfect drying action it is necessary to adjust the squeegee in such a way that when it is in operation, the rear blade

lip is bent about 45 degrees with respect to the oor at all points. It is possible to adjust the inclination of the blades by screwing

down the nuts (g. 9, ref. 1): by unscrewing the nuts the blade inclination is reduced, while by screwing the nuts the blade

inclination is increased. Moreover, check that the suction hole of the squeegee is not clogged, to let dirty water to be perfectly

drained from the oor.

Moving The Machine

To displace the machine, do as follows:

• Lift the squeegee;

• Raise the head by pressing the brush up-down button (g. 8, ref. 5) on the arrow up;

• Disengage the parking brake via the pedal (g. 8, ref. 12);

• Insert the key to release the emergency button (g. 8, ref. 2);

• Below the handgrip is a lever (g. 8, ref. 6): by pulling the lever up (g. 10, ref. 2) or pressing it down (g. 10, ref. 1),

according to whether you wish to move forward or back, the drive motor is switched on and the machine will begin to

move;

• Press the drive lever (g. 8, ref. 6) placed under the handgrip: the drive motor is started and the machine starts moving

forward;

• Adjust the running speed via the potentiometer (g. 8, ref. 1);

• If you wish to engage reverse gear during work with the squeegee lowered, you must rst stop and raise the squeegee;

• Check periodically that the detergent solution reaches the brushes/rollers and ll with solution if it runs out;

• Check cleaning quality during work and adjust, as required, the ow of solution sent to the brushes/rollers (by rotating

the cursor (g. 8, ref. 3)) and the pressure exerted by the head-brushes on the oor (via the brush up-down button (g. 8,

ref. 5) until the test pressure indicator (g. 8, ref. 8) indicates the required level).

In working conditions, if the emergency switch is accidentally pressed and the machine is switched o, when it is switched on again the

brush button must be pressed to re-activate the brushes. Never leave the machine stationary with the head lowered and the brushes in

motion: the oor could be damaged. Whenever you ll up the solution tank, always empty the recovery tank. Do not leave the machine

stationary with the suction motor on and the solution cock turned on.

• If the warning led (g. 8, ref. 9) starts ashing, it means that the storage batteries are getting at. Therefore, it is necessary

to recharge them; if you keep on working, the batteries could become damaged irreparably;

• If the suction unit revs up but does not perform suction, it means that the oater has cut in. In this case the recovery tank

must be emptied (see specic paragraph).

If for any reason the battery voltage drops considerably below the level envisaged, even temporarily, the drive lock may cut in. In this case

the machine must be switched o and then on again.

Finishing work

• Move the lever (g. 8, ref. 3) to the position “CLOSED”;

• Release the drive lever (g. 8, ref. 6) placed beneath the handle: the drive motor switches o and the machine stops;

• Raise the head by pressing the brush up-down button (g. 8, ref. 5) on the arrow up to stop the brushes (or drive discs or

rollers) and raise them to prevent them becoming permanently distorted;

• Let the suction motor run for at least 2 minutes to make sure that it is completely dry;

• By raising the lever (g. 8, ref. 11), lift the squeegee from the ground to prevent continuous pressure causing distortion of

the drying blades and to switch o the suction motor;

• Press the main switch (g. 8, ref. 2) to disable all the machine functions;

• Engage the parking brake via the pedal (g. 8, ref. 12);

• Empty and clean the recovery tank.

ADDITIONAL FUNCTIONS

The machine is provided with additional functions that can be activated by removing some fuses inside the control panel (g. 14).

FU6 Fuse Function

When fuse FU6 is removed, the electronic control of the head is enabled, in particular the following functions:

• Brush timer: if the drive is released, the brushes will stop after a few seconds; to reactivate the brushes, simply pull the

drive lever.

• Battery protection: when the batteries are at, rst the red led comes on, then the brushes lock; in this case a continuous

buzzer reminds the user that the head must be raised to prevent damage to the brushes, since the drive continues to

operate. The brush motors are re-enabled by reset of the key (g. 8, ref. 2) if the batteries have sucient load and voltage.

FU7 Fuse Function

Gel battery activation (the discharge voltages are varied for operation with the gel batteries).

FU8 Fuse Function

Water is delivered to the brushes only when the drive is activated.

Some useful tips to get the most from your scrubber dryer

In the event of particularly stubborn dirt on the oor, washing and drying can be performed in two separate operations.

17Operations Manual Hurricane 700 XTT / Hurricane 850 XTT

Pre-Washing

• Turn on the water;

• Switch on the brush motor and lower the head;

• Adjust the head pressure, which depends on the type of oor and dirt to be removed;

• Start washing with the suction motor o and the squeegee lifted;

The ow of water must be dosed in proportion to the desired advance speed: the slower the machine goes, less water comes

down. Insist on washing the dirtiest spots: in this way the detergent has the time to perform its chemical action for the

detachment and suspension of dirt, and the brushes to develop an eective mechanical action.

Drying

Lower the squeegee and with the suction unit operating pass again on the same area you have previously washed. In this way you

obtain a result that is similar to a thorough washing and the following operations of ordinary maintenance will certainly take less

time. To wash and dry at the same time, operate the brushes, water, squeegee and suction motor simultaneously.

Never leave the machine unmanned with the suction unit running.

Draining O Dirty Water

Use the individual protection devices suitable for the operation to be performed. Perform the draining operations with the machine

disconnected from the power supply.

The drain hose of the recovery tank is located at the rear left side of the machine. To empty the above-mentioned tank:

• Take the machine next to a drain;

• Stop the machine and press the emergency button (g. 8, ref. 2); engage the parking brake by means of the pedal

(g. 8, ref. 12);

• Take o the tank cap (g. 15, ref. 1) from the recovery tank (g. 15, ref. 5);

• Detach the drain hose (g. 15, ref. 2) from its seat, holding it in correspondence with the xing spring (g. 15, ref. 3) and

pull it horizontally;

• Keeping the hose end as much high as possible, take o the drain (g. 15, ref. 4) from the hose by unscrewing it;

• Lower the hose end gradually, checking the intensity of the jet of water with reference to its height from the ground;

• Check the amount of residual dirt in the recovery tank and wash it inside, if necessary. To facilitate the cleaning and total

drain, it is better to unhook it from the solution tank and lift it;

• When the dirty water has been totally drained, lower the recovery tank (if it

has been previously lifted) and hook it again to the solution tank;

• Put back the cap (g. 15, ref. 1) on the recovery tank, making sure that it is

perfectly closed;

• Close the drain hose (g. 15, ref. 2) with the cock (g. 15, ref. 4)

screw-tightening it; check that it is perfectly closed and ret the hose in its

housing.

While washing the recovery tank never remove the suction lter (g. 18, ref. 2) from its seat

and never direct the jet of water towards the lter itself. Now it is possible to proceed with a

new washing and drying action.

18 Operations Manual Hurricane 700 XTT / Hurricane 850 XTT

Draining O Clean Water

Use the individual protection devices suitable for the operation to be performed.

Perform the draining o operations with the machine disconnected from the power

supply.

To empty the tank:

• Take the machine next to a drain;

• Stop the machine and press the emergency button (g. 8, ref. 2);

engage the parking brake by means of the pedal (g. 8, ref. 12);

• Detach the drain hose (g. 16, ref. 1) from its seat, holding it in

correspondence with the xing spring (g. 16, ref. 2) and pull it

horizontally;

• Keeping the hose end as much high as possible, take o the drain cap

(g. 16, ref. 3) from the hose by unscrewing it;

• Lower the hose end gradually, checking the intensity of the jet of water

with reference to its height from the ground;

• When the contents have been totally drained from the solution tank,

close the drain cap (g. 16, ref. 3) screw-tightening it; check that it is

perfectly closed and ret the hose in its housing;

The water and detergent solution can also be used to wash the recovery tank.

Periods Of Inactivity

If the machine is to remain unused for a long time, the squeegee and brushes (or drive

discs or rollers) must be dismounted, washed and kept in a dry place (preferably packed

in a plastic envelope or sheet), sheltered from dust. Park the machine with the parking

brake engaged.

Furthermore, make sure that the tanks are completely empty and perfectly clean.

Recharge the batteries completely before putting them in the storehouse. During long

periods of inactivity recharge the batteries (once every two months at least) to preserve

the storage batteries constantly at the maximum charge.

Maintenance And Battery Recharging

Do not check the battery charge by producing sparks. The batteries give o inammable

vapours: put out any re or embers before checking and lling up the batteries. Perform the operations described below in airy

environments.

To avoid permanent damages to the batteries, never let them get at completely. Remember that when the proper red led (g. 8,

ref. 9) ashes on the control panel, it is necessary to recharge the batteries.

Recharging Procedures

Lead Batteries With Liquid Electrolyte

It is necessary to check the level of the electrolytic solution in order that it always covers the lms of the elements, adding the

necessary distilled water.

During recharging do not let the temperature of the electrolyte exceed 45°C.

19Operations Manual Hurricane 700 XTT / Hurricane 850 XTT

To recharge proceed as follows:

• Stop the machine and press the emergency button (g. 8, ref. 2);

• Engage the parking brake by means of the pedal (g. 8, ref. 12);

• Connect the battery-charger to the battery wiring connector (g 17, ref. 1);

• Recharge according to the instructions written in the manual to the battery-charger;

• Switch o the battery charger before disconnecting the connectors;

• Disconnect the battery charger connector from the battery wiring connector;

• If using Flooded Lead Acid batteries, at the end of the recharging time check the battery intensity with a densimeter: if

one or more elements are at and the remaining ones completely charged, the battery is damaged and must be replaced.

MAINTENANCE INSTRUCTIONS

! DANGER: Never perform any maintenance operations without rst disconnecting the batteries. Maintenance on the electrical circuit and

all other operations not explicitly described in this manual must be performed by specialized personnel only, in compliance with current

safety legislation and as described in the maintenance manual.

! DANGER: Before lifting/rotating the tank to access the compartment, its contents must rst be emptied, then insert the safety bracket in

position to prevent the tank from accidentally closing again, see chapter “SAFETY INFORMATION”.

Maintenance - General rules

Performing regular maintenance according to the Manufacturer’s instructions improves performance and extends the working life

of the machine.

When cleaning the machine, observe the following precautions:

• Avoid using pressure washers. Water could penetrate the electrical compartment or motors leading to damage or short

Squeegee Blades: Check And Replacement

The blades of the squeegee are used to scrub from the oor the lm of water and detergent thus allowing a perfect drying. As

long as time goes by the continuous scraping rounds o and splits the sharp edge in contact with the oor, thus reducing the

drying ecacy and therefore requiring the replacement of the blades. Therefore, often check their state of wear and tear.

Exchanging or replacing the blades:

• Stop the machine and press the emergency button (g. 8, ref. 2); engage the parking brake by means of the pedal

(g. 8, ref. 12);

• Lower the squeegee by using the proper lever (g. 8, ref. 11);

• Take o the squeegee (g. 2, ref. 8) from its supporting plate (g. 9, ref. 2) by unscrewing completely the two knobs

(g. 9, ref. 3);

• Slide out the sleeve of the suction tube (g. 9, ref. 4) from the squeegee;

Front blade:

• Unscrew the knobs (g. 19, ref. 1);

• Remove the blade clamps (g. 19, ref. 3);

• Take out the blade (g. 19, ref. 4);

• Fit in the same blade inverting the edge in contact with the oor until all the four edges are worn, or else t in a new

blade;

• Put the blade clamp (g. 19, ref. 3) back;

• Screw down all the knobs (g. 19, ref. 1);

Rear blade:

• Unhook the hook clamp (g. 19, rif. 8);

• Slide out the two blade clamps (g. 19, ref. 7) by rst pushing them outwards with respect to the squeegee unit

(g. 19, ref. 5) and then taking them out;

• Remove the blade (g. 19, ref. 6);

• Fit in the same blade inverting the edge in contact with the oor until all the four edges are worn, or else t in a new

blade embedding it in the screws of the squeegee unit (g. 19, ref. 5);

• Put the two blade clamps (g. 19, ref. 7) back, centering the largest part of the slots on the xing screws of the squeegee

unit (g. 19, ref. 5) and then pushing the blade clamps towards the inside of the squeegee itself;
