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).

Summary

Inspection of the Electrical Layout

Check Electrical Layout Functions

Check the functions of switches, motors, and solenoid valve.

Check Control Functions and Brush Coupling

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

Control Chopper Operation

Control the operation of the chopper (Machine with traction).

Adjust Chopper-Card Settings

Adjust the chopper-card, including trimmer 'I' for first speed and trimmer 'L' for acceleration.

Battery Check Card Adjustment

Check and Adjust Battery Check Card Set-up

Check the set-up of the battery check card and adjust using microswitches.

Traction Motor Test

Check Carbon Brush Motor Conditions

Check Differential Gear

Check Bearing Noiselessness and Functionality

Brush Adjustments

Adjust Spring Belt Tightener

Adjust spring belt tightener to a compression length of 27mm.

Adjust Brush Inclination (Without Traction)

Adjust brush inclination and screw distance to brush base about 1mm.

Adjust Brush Bases Inclination (Point III)

Adjust screws M6 for brush base inclination of 3-4 cm.

Brake Adjustment

Adjust Hand Brake Lever

Verify hand brake lever clicks 3-4 times and adjust cable nut.

Adjust Brake Disk

Verify uniform brake effect by checking wheel blockage.

Squeegee Adjustment

Adjust Squeegee Back Rubber Inclination

Adjust Squeegee Wheel Height

Adjust Squeegee Lifting Cable

Functional Machine Test

Check Tank Tightness and Water Flow

Check Squeegee Wheels and Brush Inclination

Check Water Cock and Braking Efficiency
