GENERATOR
The.
generator normally needs little care other than a periodic check of
the brushes, ,commutator and collector rings. If a major repair job on
the generator should become necessary, have the equipment checked by
a competent electrician who is thoroughly familiar with the operation of
electric generating equipment. Continuity tests may be performed with-
out disassembly of the generator.

remove them as one assembly from the adapter. Screw driver slots in
the adapter provide for prying the frame loose. Be careful not to iet
the frame assembly restor dragon the armature.
