Main Broom Motor Amperage Check (Continues)
If the amperage is higher, perform the following procedures to detect and correct it:
• Check the relevant fuse (FA) for proper tightening
• Check if there is dust or dirt (cords, cables, etc.) on the broom drive hub.
• Check that the driving belt is efficient and properly tightened.
• Check the motor carbon brushes (see the procedure in "Main Broom Motor Carbon Brush Check/Re-
placement")
• If necessary, disassemble the motor (see procedure in the next paragraph), and check the condition of
all its components
If the above-mentioned procedures do not lead to a correct amperage, the motor must be replaced (see
