8. Check the functioning of the chopper.
9. If necessary, calibrate the chopper card as follows:
• raise the machine (free traction wheels);
• unscrew the rear instrument panel to access
the chopper;
• set the continuous voltage measurement tester with a full scale of 50V;
• insert the test prods on the fastons marked with M+ and M- on the chopper card;
• switch on via the main key;
• select the forward movement until activating
the movement microswitch (so you can hear the click of the relays) slightly rotating the potentiometer on the handlebars with respect to zero;
• in that moment, the voltage measured by the test prod must be 3-5V. If necessary, adjust the VMIN trimmer so the output voltage is at the required value;
• at this point, press the operation levers fully down until you reach maximum speed. You should see a value of 24V (battery maximum); if this is not the case, adjust the
VMAX trimmer to obtain the required output
voltage;
• acceleration adjustment: rotate the ACC trimmer clockwise. This adjustment brings the voltage to the maximum required value (24V) in about 7-8 seconds;
• check the reverse gear is functioning;
• check the motor braking (releasing the
accelerator, the machine must stop within about 1 metre)
