MAINTENANCE AND INSPECTION
1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Inspecting the carbon brushes (Fig. 7)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon brush
No. ⓑ shown in the fi gure when it becomes worn to or
near the "wear limit" ⓐ. In addition, always keep carbon
brushes clean and ensue that they slide freely within the
brush holders.
