READ THE USE AND MAINTENANCE HANDBOOK

Inspection of the electrical layout

1. Check the functions of the electrical layout: switches, motors,

solenoid valve.

2. Check the control functions and the coupling and uncoupling of the

brushes.

3. Control the operation of the chopper

(Machine with traction).

4. If necessary adjust the chopper-card

follows:

•Lift the machine (Traction wheels without

contact to the floor)

•Open the handlebar unscrewing the four

underlying screws

•Fix the clamps of the tester (V-DC) to the

connections M+ and M- of the chopper-

card

•Switch on the main key

•Insert the forward gear until the 1°

Microswitch snaps (first speed)

•The tester should indicate 9-10V. If

necessary adjust the trimmer “I” (first

speed), so that the above mentioned

voltage is obtained

•Activate the forward gear completely, so

that the 2°microswitch snaps. The

tester must indicate 24V (max. battery);

Otherwise control the voltage of the

battery and control the cables.

•Acceleration adjustment: Set the

trimmer “L” (ACC), so that its position is

turned clockwise about 30°/45° to the

central position. With this adjustment you

obtain the desired voltage (9-10V or

24V) in about 4 seconds.

•Check the function reverse gear

•Check motor braking (after release of

the handle bar the machine should stop

in about 1 meter).

Adjustment brushes base

1. Adjustment the screw, so that the weight of the tank doesn’t rest

completely on the frame; fix the adjuster nut.

2. Adjust the lifting tie rods: adjust the fork of the vertical tie rod

so that, with the lift base, it doesn’t interfere with tank.

3. Adjust the fork of the horizontal tie rod avoiding

that the base

lifting arms interfere with the frame and that the brush cover

doesn’t contact the solution tank. Make sure that, without brush,

the brush plate is almost to touch the floor (0 - 1 mm).

4. Adjustment Point III: Adjustment screws M6,so that the lower

brush bases touch on the back and it’s higher in front of 2-3 mm.

Screw that is on support of Point III must come out about 20 mm.

5. Fix adjuster nut.

6. Adjustment horizontal inclination: place machine on a levele floor;

mount brushes and lower base on the floor; loose the screw

the left lifting arm so that the base touches

the floor, support of

the base will position itself correctly; fix nut and bolt.

7. This function assure a correct ranging on the floor of the brush

base for a uniform cleaning on the ……….floor?

8. Check the spring of unloading of pressure screwing the screw

M6 on the tie rod making it goes out 2-3 mm., so that pressure of

the base is 15-16 Kg.

9. Assemble the joint chain of transmission so that a distance of 2

mm. between two hubs is obtained and tyre toothed star is

between two hubs, works correctly, avoiding vibration and shift.

10. Fix dowels and adjuster nuts.

11. Check tension of transmission belt working of screw M8, so that

the thread goes out from support of about 28-29 mm.

the nut on the brake cable.

2. Adjustment of the brake disk. Verify the uniform brake effect. Try

to turn the machine with insert brake to the left and to the right:

Check if the wheels remain blocked in the same way.

Adjustment Squeegee

1. Adjustment of the inclination controller back rubber in working

conditions, in order to obtain a uniform inclination.

2. Adjust the wheel height with the corresponding hand wheel.

Check, if the rubber has an inclination about 30°-45° and is not

pressed on the floor or in a lifted position.

3. Adjust the length of the lifting cable with the corresponding

controller, until the back rubber is lifted about 4-5 cm from the

floor. The squeegee should not have contact with the tank outlet.

Afterwards fix the nut.
