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