hours
oil-free cloth. Do not remove smooth
patina build-up from contact face.
Remove grooves and polish surface
using fine Emery cloth or skim on lathe
(possibly recut and duburr slots).
Every 48 months
Check ball bearings for noise, running
smoothly. Service life approx. 20 000
hours (lubricated for life); however,
service life depends on speed,
environmental conditions and load.
Caution! Do not remove the armature
before short-circuiting the magnetic
circuit using an appropriate short-
circuiting ring (otherwise voltage drop of
approx. 25%). Observe dismantling
instructions!
Bearings must be replaced
by the manufacturer or a
certified workshop only.
Regularly (depending on degree
of soiling)
Cleaning:
Blow-clean the machine using dry, oil-
free compressed air. Do not use
cleaning agents that damage the
coating. Do not use inflammable
cleaning agents.

Regularly
Check coating.
If the protective coating is
sufficiently damaged, repaint to
prevent risk of corrosion
(recommended).
Skilled personnel
If the machine has not been in
use for a long time (more than 6
months).
Check the insulation resistance of the
windings (greater approx. 1-5 mega-
ohm). To measure the insulation
resistance disconnect all outgoing lines
from the generator. Contact the
manufacturer if the resistance reading is
less than 1 mega-ohm.
