10. AUTO-STOP CARBON
BRUSHES(See G))
When the resin insulating tip (10)
inside the carbon brush (11) is
exposed to contact the commutator
(9), it will automatically shut off the
motor. After prolonged use the carbon
brushes will wear. This machine is
fitted with Auto Stop Carbon Brushes
that will automatically shut down the
motor when the brushes become
worn. When this occurs, both carbon
brushes should be replaced. Keep the
carbon brushes clean and free to slip
in the holders. Both carbon brushes
should be replaced at the same time.
Use only identical carbon brushes.
11. TO REPLACE THE
BRUSHES (See H1,H2)
Disconnect the plug from the power
supply.
Unscrew the carbon brush cap(c) with
screwdriver.
