RECEIVING THE MACHINE

Immediately check, when receiving the machine, that all the materials indicated on delivery documents have been received and also that the machine has not been damaged in transit. If it has been damaged, this damage must be immediately reported to the shipper and also to our customer’s service department. Only acting promptly in this manner will make it possible to receive missing material and to be compensated for damage.

INTRODUCTION

This is an automatic scrubber which, via the mechanical action of the rotating brush and the chemical action of a water/detergent solution, can clean many types of hard fl ooring. As it advances, it also collects the dirt removed and the detergent solution not absorbed by the fl oor.

The machine must be used only for this purpose. Even the best machines will only work well if used correctly and kept in good working order. We therefore suggest you read this instruction booklet carefully and re-read it whenever diffi culties arise while using the machine. Please contact our technical service department or your dealers if you have any questions about the machine.

TROUBLESHOOTING GUIDE

INSUFFICIENT WATER ON THE PAD

1. Check the valve – located beneath the symbol – (1) is turned on.

2. Check there is water in the solution tank.

THE MACHINE DOES NOT CLEAN WELL

1. Check the wear of the scrubbing pad and, if necessary, replace it.

THE SQUEEGEE DOES NOT DRY WELL

1. Check that the squeegee blades are clean.

2. Adjust the inclination of the squeegee.

3. Ensure the vacuum hose is correctly inserted in its housing in the recovery tank.

4. Check the inner fi lter inside the recovery tank to ensure that it is clean and, if necessary, clean it thoroughly.

5. Disassemble the entire vacuum unit and clean it.

6. Replace the squeegee blades, if worn.

7. Check squeegee wheel adjustment.

TOO MUCH FOAM IS GENERATED

Check that low-foam detergent is being used. If necessary add a small amount of defoamer liquid to the recovery tank.

Remember that more foam is generated when the fl oors are not very dirty. Dilute the detergent more when cleaning fl oors that are not very dirty.

CHOOSING AND USING THE BRUSHES

POLYPROPYLENE BRUSH (PPL)

Used on all types of fl oors. Good resistance to wear and tear, and hot water (no greater than 140°F (60°C)).

NYLON BRUSH

Used on all types of fl oors. Excellent resistance to wear and tear and hot water (even over 140°F (60°C)).

ABRASIVE BRUSH

The bristles of this type of brush are coated with highly aggressive abrasives. It is used to clean very dirty fl oors.

THICKNESS OF THE BRISTLES

Thicker bristles are more rigid and are therefore used on smooth fl oors or fl oors with small joints. On uneven fl oors or those with deep joints, it is advisable to use softer bristles which can enter the gaps easier. Remember that when the bristles are worn and too short, they will become rigid and are no longer able to penetrate and clean deep and cause the brush to bounce.

PAD DRIVER

A pad driver is recommended for cleaning smooth surfaces. There are two types of pad drivers:

1. The traditional pad holder is fi tted with a series of anchor points that allow the abrasive fl oor pad to be held while working.

2. The CENTER LOCK type pad holder not only has anchor points, but also a snap-type central locking system made of plastic that allows the abrasive fl oor pad to be centered and held without any risk of it becoming detached.

1. Verify the functionality of the variable speed control card.

2. If necessary adjust the traction card:

• Lift up at least one of the traction wheel .

• Remove the handlebar for access to the electric controls.

• Set-up the tester in volt-meter with 50V maximum.

• Put the tester pins on the faston M+ and M- of the speed control card.

• Turn on the key master switch.

• Pull the switch lever until you hear the forward fi rst micro switch click (fi rst speed).

• The tester has to show a voltage between 14 and 15V. If the reading is different adjust the trimmer (fi rst speed) to have the right output voltage.

• Completely pull the switch lever until the second (maximum) speed micro switch is pressed. A voltage of 24V (the same as the battery voltage) has to be read; in opposite case verify the power connections and the conditions of the battery.

• Acceleration adjustment: Adjust on the “ACC” trimmer to let it be between 30° and

45° respect the central position rotating clockwise. Verify that with this regulation the machine reach the maximum speed in 4 second.

• Check the backward direction .

• Check the braking power of the traction motor. At maximum speed the machine has to stop in about 1 meter.

ELECTRICAL SYSTEM

1. ELECTRIC HARNESS INSPECTION

BATTERY CHECK CARD – HOUR METER

1. Verify that turning on the machine the battery check card has the following starting sequence:

• Turning on of the LED which correspond to the set-up (red LED = “0”).

• Turning on of all the LEDs (check of the lamps)

• Turning on of the LEDs depending on the charge of the battery

2. Verify the hour meter functionality

• To verify which is the set-up you simply need to turn on the machine and check which is the fi rst LED that turns on. Counting the LEDs since the left side any LED correspond to a position and the LED which turn on correspond to the current set-up.

• Verify that if the machine uses wet cell batteries the adjustment is on position 1.

• Verify that if the machine uses GEL batteries the adjustment is on position 4.

WARNING: A wrong set-up of the battery control card can compromise the battery effi ciency and damage then in irreversible way.

• Lower the brush deck to the fl oor with a brush installed.

• Loosen the M8 bolt and the M8 nut that attach the brush deck to the left arm.

• Loosen the nut and the bolt that attach the brush deck to the idler arm.

• Verify that the brush deck correctly lays on the fl oor and the brush touches the fl oor completely.

• Tighten the nut and its M8 bolt to lock the left arm of the brush deck.

• Lift up the front side of the brush deck to let it be 5 mm from the fl oor relative to the back side.

• Tighten the M8 nut to secure the brush deck in position.

Check that the pan head screw on the back side is adjusted near the fl at part of the brush deck. The distance between the screw head and the brush deck has to be 1 - 2 mm when the brush is locked and the brush deck is lowered.

BRAKE ADJUSTMENT

1. Verify that the brake on the left hand wheel locks the wheel when active.

2. Otherwise adjust as follows:

• Verify the adjustment with a functional test

47

SQUEEGEE ADJUSTMENT

1. Adjust the inclination adjuster of the squeegee blade until the blade has a common inclination over its entire length.

2. Adjust the height of the wheels using the knob checking that the blade has an inclination between 30 and 45 degrees.

3. Verify the cleanliness and sealing of the squeegee hose adapter.
