Preventive
Maintenance
A f t e r 100 hours on new brushes, or brushes in
generators that have not been in use over a long
period, remove the end frame covers and inspect the
brushes, commutator and collector rings. If there is no
a p p r e c i a b l e wear on t h e brushes, the inspection
interval may be extended until the most practicable
period has been established (not to exceed six months).
To prevent damage to the commutator or the collector
rings, do not permit the brushes to become shorter
than 3/4 inch.
Keep the generator clean inside and out. Before
removing the end frame covers, wipe off the loose dirt.
The loose dirt and dust may be blown out with low
pressure air (25 psi or 172 kPa maximum). Remove all
greasy dirt with a cloth.

sufficient.
Remove the inspection hole cover and lubricate the
