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 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
on
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.

Brake adjustment
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.
