turns off the machine to protect the motor if it draws exces-
sive current.
If the machine shuts down unexpectedly, release the
footswitch. Place the switch in the O-OFF position and
unplug the machine. Remove any tube from the machine.
Follow the Pre-Operation Inspection and Machine and
Work Area Set-up sections to confirm that the machine
works properly.

Check motor brushes every six months, the brushes
should be changed if the length is less than 5 mm (0.2").

machine is unplugged.

(Figure 16) and remove cover (Some screws are
retained to cover).

caps (Figure 17). Gently remove the carbon brushes
and check the length (Figure 18). If brush length is
less than 5 mm (0.2"), change brushes.

brush tabs with the reliefs in the brush holder.
