damages, it is necessary to either change the faulty device or conduct repair.
Unexpected stop of vehicle during drive:
• check if the range indicator and speedometer are lit
• check the signals of speed controller diode
• check electric hoses for breaks or loosen connections
• check the fuse 7,5 A (20A) in steering circuit
• check the fuse 200 A (250A) in power supply circuit
• check in the sequence as follows: solenoid, key-switch, Not-Aus, accelerator pedal, each
battery, speed controller, F-R switch and motor
During drive with heavy load vehicle drives slowly or stops:
• check proper work of the hand brake lever switch
