Lubrication
Al
bearing and friction
points of
the
unit are adequately
lubricated
at the works.
Replenishment
of oll
and
grease is only necessary after
approximately
2 years of normal
use of the record player as the
most important bearing points
(motor
bearings)
have sintered me-
tal
bushes.
Bearing points and friction
faces
should be lubricated sparingly
rather than generously.
lt is important
that no oil grease
should come in contact with the
friction faces of the flat belt,
drive pulley and flywheel rotor,
otherwise slip will
occur.
When
using
different
lubricants,
chemical decomposition can
of-
ten take place. To prevent lubri-
cation failure we recommend us-
ing the original lubricants
stated
below.
