9-7. Carbon Brushes Inspection and Replacement
Check Carbon Brushes for wear periodically.
This machine has a "switch-off brush" which
automatically stops the motor to protect it when the
carbon brushes reach the application limits.
When the brushes reach the limits, replace both
brushes with the new ones according to the following
procedures. (Fig.34)
Check - machine failure.
(1) Remove the Brush Cap with a straight slot
screwdriver.
(2) Remove the worn-out Carbon Brush and replace
it with a new one. Then reattach the Brush Cap.
(3) After replacing the Brush, operate the unit for
about ten minutes with no load.
