  • Inspect carbon brushes

  • Instructions

  • Inspecting the carbon brushes (Fig. 7)
    The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. n addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
