TROUBLESHOOTING
OPEN CIRCUIT
The circuit breakers (20) and (21) determines the open circuit. This system prevents the main motor and broom motor circuits
from being damaged in case of overload.
In case of open circuit, possible causes are:
Main motor (for main broom): The circuit breaker (21) determines the open circuit. Possible causes:
There are bulky debris or cords around the broom or between the broom and its ange (remove the debris).
The broom pressure on the ground is excessive (check the broom height).
The main motor electrical input is too high (check the electrical input).
Wait at least 2 minutes after the open circuit. After repairing, press the circuit breaker button (21).
Side broom motor: The circuit breaker (20) determines the open circuit. Possible causes:
There are bulky debris or cords around the broom or between the broom and its ange (remove the debris).
The broom pressure on the ground is excessive (check the broom height).
The side broom motor electrical input is too high (check the electrical input).
Wait at least 2 minutes after the open circuit. After repairing, press the circuit breaker button (20).
THE MAIN BROOM DOES NOT TURN
Possible causes:
The battery voltage is too low, the warning light (4) is on (charge the battery).
The main motor carbon brushes are worn (replace).
The motor is faulty (repair/replace).
The motor driving belts are inefcient or broken (replace).
The wiring harness is damaged (repair).
The relay is faulty (replace).
There is an open in the circuit breaker (reset).
The hopper microswitch does not work (adjust/replace).
The main switch is damaged (replace).
The battery charger-function control is faulty (replace).
THE SIDE BROOM DOES NOT TURN
Possible causes:
The battery voltage is too low, the warning light (4) is on (charge the battery).
The motor carbon brushes are worn (replace).
The motor is faulty (repair/replace).
The wiring harness is damaged (repair).
There is an open in the circuit breaker (reset).

Drive the machine on a level ground that is suitable for checking the skirt height.
Turn the main switch (1) to “0”.
Check that the distance from the ground of the side skirts (A and B) is 0 to 0.08 in (0 to 2 mm).
Check the skirts for integrity, cuts or tears, which can reduce the machine vacuum capabilities. If necessary replace the
side skirts (see the procedure in the relevant paragraph).
Check that the front and rear skirts (C and D) slightly rub on the ground. Check the skirts for integrity, cuts or tears, which
can reduce the machine vacuum capabilities. Note that the front skirt has typical vertical cuts (E). If necessary replace the
