On consignment of the machine

When the machine is delivered to the customer, an

immediate check must be performed to ensure all the

material mentioned in the shipping documents has

been received, and also to check the machine has not

been damaged during transportation. If this is the

case, the carrier must ascertain the extent of the

damage at once, informing our customer service

office. It is only by prompt action of this type that the

missing material can be obtained, and compensation

for damage successfully claimed.

Introductory comment

This is a floor scrubber-dryer which, via the mechanical

abrasive action of a brush and the chemical action of a

water/detergent solution, can clean any type of flooring.

As it advances, it also collects the dirt removed and the

detergent solution not absorbed by the floor.

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

read it again whenever difficulties arise while using the

machine If necessary, remember that our assistance

service (organised in collaboration with our dealers) is

always available for advice or direct intervention.

MACHINE PREPARATION

1. HANDLING THE PACKED MACHINE

The machine is contained in specific packaging with a pallet for the handling

with fork trucks. It is not possible to place more than two packages on top of

each other.

The total mass of the packed machine is 105 kg per Simpla 45-50

The overall dimensions of the package are:

A: 1150 mm B: 610 mm C: 1250 mm

2. HOW TO UNPACK THE MACHINE

1. Remove the outer packaging

2. The machine is fixed to the pallet with wedges which block the wheels

3. Remove these wedges

4. Use a chute to get the machine down from the pallet, pushing it

backwards. Avoid violent blows to the base

5. Keep the pallet for any future transport needs

3. HANDLEBAR HEIGHT

The handlebar can be adjusted in height in three different positions:

1. Unlock the lever

2. Position the handlebar to the desired height, in correspondence with the

locking holes

3. Release the lever

MACHINE PREPARATION

4. ASSEMBLING THE SQUEEGEE

For packaging reasons, the squeegee is supplied disassembled from the

machine, and must be assembled as shown in the figure, inserting the small

column of the squeegee into the coupling mechanism until the lever is triggered.

Insert the squeegee tube in the appropriate sleeve, ensuring that the tube lies

to the right of the lifting cable.

5. ADJUSTING THE SQUEEGEE HEIGHT

The height of the squeegee must be adjusted on the basis of the state of wear

and tear of the rubber. To do this, turn the knob (2) anticlockwise to raise the

squeegee, and clockwise to lower it.

Note: the right and left wheels must be adjusted to the same level, so the

squeegee can work parallel to the floor.

6. ADJUSTING THE SQUEEGEE INCLINATION

During working operation, the rear rubber is slightly tilted backwards (by about

5mm) in a uniform way for its whole length. If it is necessary to increase the

bend of the rubber in the central part, you must tilt the squeegee backwards,

rotating the adjuster (1) anticlockwise. To increase the bend of the rubber at

the sides of the squeegee, rotate the adjuster clockwise. When fully adjusted,

fix the locknut.

7. RECOVERY TANK

Open the cover and check the suction cap (2) is correctly blocked (insert the

notches in their housings, rotating the cap clockwise) and correctly connected

to the tube leading to the suction motor.

In addition, check the squeegee tube (1) is correctly inserted in its housing,

and that the drainage tube cap at the front of the machine is closed.

MACHINE PREPARATION

8. SOLUTION TANK

Remove the filler cap and check that the solution filter, on the bottom left, is

fitted properly.

9. DETERGENT SOLUTION

Fill the solution tank with clean water at a temperature no greater than 50°C and

add liquid detergent in the proper concentration, following the instructions of the

manufacturer. The formation of excess foam could damage the suction motor, so

use only the minimum amount of detergent necessary. Reassemble the cap.

ATTENTION! always use low foam detergent. To avoid the

production of foam, before starting to clean, put a minimum quantity

of antifoam liquid into the recovery tank. Never use pure acid.

10. ASSEMBLING THE BRUSH

1. With the base up, insert the brush and position it in line with the plate

beneath the base.

2. Connect the plug to the power supply.

3. Lower the base, press the brush switch (2), push the man present lever (3)

on the handlebar.

At this point, the brush is fixed.

ATTENTION! During this operation, check there are no people or

objects near the brush.

3. Using the knob (1), adjust the height of the splash guard rubber so that it

rests on the floor.

The adjustment should be repeated periodically depending on the wear of the

brush

WORK

PREPARING TO WORK

1. Carry out the operations to prepare the machine

2. Connect the plug to the power supply.

3. Press the solenoid valve switch (4)

4. Press the suction switch (5)

5. Press the brush switch (6)

6. By means of the tap lever (1), regulate the quantity of detergent solution - it must

be sufficient to wet the floor evenly, but not so much that it leaks from the splash

guard. Remember, however, that the correct quantity of solution always

depends on the type of floor, the degree of dirtiness and the speed used.

7. Release the lever (2) and lower the base.

8. Lower the squeegee by means of the lever (3)

9. Check the parking brake (4) is released

10. The machine starts moving when the man present lever (1) is pushed

forward. During the first metres, check there is sufficient solution and that

the squeegee dries perfectly.

The machine will now start to work efficiently until the detergent solution

runs out.

If problems occur during work, release the man present lever and quickly push

the emergency brake on the left. This command blocks the drive of the

machine. To start working again, once you have solved the problem, release

the parking brake and push the man present lever forward.

WORK

OVERFLOW DEVICE

The machine is fitted with a float which intervenes when the recovery tank is

full, causing the suction tube to close. In this case, it is necessary to empty the

recovery tank, removing the drainage tube cap.

ATTENTION! this operation must be carried out using gloves to

protect against contact with dangerous solutions

FORWARD MOVEMENTS

The traction of these machines is obtained by means of the brush which,

working slightly inclined, is able to drag the machine forwards. To move the

machine, insert the power supply plug into the socket of the power grid, then

rotate the man present lever (2) on the handlebars forward (forward

movement).

ATTENTION! When making even brief reverse movements,

check the squeegee is raised.

BRAKE

The machine is equipped with a braking system controlled by lever (1) to the

left, which serves as a parking and emergency brake.
