4. Inspecting the carbon brushes: (Fig. 5)
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 figure when it becomes
worn to or near the "wear limit". In addition, always
keep carbon brushes clean and ensure that they
slide freely within the brush holders.
Replacement methods
Disassemble the brush cap with a minus-head
screwdriver. The carbon brush can then be easily
removed.
