Requirements for Periodic Maintenance

Periodic cleaning and application of fresh grease to the
mechanical detent notches in the stationary base is
necessary to minimize wear of the mechanical detents,
thereby maximizing the useful service life of the
BH-NRE. This can be easily accomplished by simply
removing the protective cover, cleaning and re-greasing
the detent notches, and then reinstalling the protective
cover per the procedures detailed in this document.
The dovetail slide does not need to be removed to
perform this periodic maintenance. If the equipment
sees heavy usage, this service should be performed on a
3
six-month interval
.

Problems with the Turret Assembly

A few problems with the turret assembly can
sometimes be found in the reassembled nosepiece. The
first will be seen if one or more of the mechanical
detents are excessively worn (see
cause radial float of the revolving turret in one or more
of the objective positions, and these objectives will have
trouble returning to and maintaining their proper index
position.
The other problem that may be seen is caused by
overall float of the revolving turret, relative to the
center point of the stationary base. If there is excess
play in the center-pivot ball, such that the turret is not
held in the exact center point, the revolving turret may

Field experience has shown that even heavily used scopes (such as those used in
hospitals and clinical lab settings), when lubricated on a six-month interval, can be
expected to provide many years of trouble-free service.

1). This will
move slightly, resulting in poor objective centering and
all that that entails. This problem may be encountered
if the threaded retaining ring has not been properly
snugged down, or if the center pivot-adjustment screw
has not been properly adjusted to remove the play in
the center-pivot mechanism.
