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 battery check card

1. Check-up the right set-up of the battery check card. The

adjustment can be performed by microswitches.

2. The possibles configurations are the following:

The right configuration is one of the two

above depending on

the battery type.

Collaudo Motore Trazione

1. Check the carbon brush motor conditions under the plastic

lids.

2. Check the differential gear noiselessness and funtionality:

stop one wheel anf verify that the free wheel turn correctly.

3. Check the noiselessness and functionality of bears where

shafts turn.

Inspection waterworks

4. Check the cleanness and the positioning of the solution tank

filter.

5. Fill the solution tank completely with water.

6. Check the tightness of the hoses, solenoid valve and

regulation of the cock.

7. Make sure, that with opened cock the solution arrives

continuously on the floor.

Inspection of suction

1. Check the function of the filter – float.

2. Check, if the cover on the recovery tank is airtight.

3. Check if the suction hoses and the squeegee hose are

airtight.

4. Check the tightness of the squeegee opening.

5. Verify the tightness of the exhaust pipe and tap.

1. Adjustment spring belt tightener

to a compression length of

27mm.

2. Adjustment inclination: Let down the brushes and adjust the

distance of the screw M8 to the brush base about 1mm.

Afterwards fix the nut. Excessive screwing leads to the effect,

that the machine pulls to the right.

3. Adjustment advancement without traction: Screw the knob

with the plastic thread. Attention: excessive screwing

increases the traction effect and decrease at the same times

the width of the cleaned floor.

4. Adjustment inclination on machine with traction: if necessary

adjusts the Knob in a way, that neutral machine behaviour is

obtained.

5. Adjustment Point III: Adjustment screws M6, so that with

lifted brush bases an inclination about 3-4 cm of the brush is

obtained. Make sure, that the brush motor does not touch the

solution tank. Fix the nut.

6. Adjust the support screw, so that the weight of the tank

does not rest completely on the frame; fix the nut.

7. Adjustment of the tie rods: adjust the fork of the vertical tie

rod, so that with lifted brush head no interferences with the

tank occur.

8. Adjust the fork of the horizontal tie rod and avoid, that the

lifting arms of the brush base do not touch the frame and the

brush cover do not have contacts with the solution tank.

Furthermore check, if without brushes the brush holder

touches the floor (0-1 mm).

9. Check, if the screw with the round head rest on the plain

top of the brushes. The play between head and brush must

be maximally 1-2 mm with coupled brushes and lowered

brush head.

1. Adjustment hand brake: Verify if the lever does not snap

more than 3-4 times. If necessary restore the right execution

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.

4. Check, if the Spring ring is completely closed.
