necessary.)
Arm height adjusting
With slide stopper relaxed, height of arm can be
adjusted by turning slide knob. But as arm slowly sinks
by itself when slide stopper is loosened, an easy way to
adjust arm height is, first lift arm to maximum height,
then let arm sink while holding stopper between fingers,
and finally fasten stopper just when arm comes down to
right place.
Arm must be just so high that sub arm may precisely
parallel record disk surface.
Arm balancing
z
Horizontal balancing
Main arm is designed to maintain itself always
level. But horizontal balancing is still necessary
to distribute bearing load evenly and thereby
realize best trackability. To achieve this balance,
shell and sub weight alone normally suffice. First
position sub weight A closest to the fore, or sub
weight B at white-color balancing point mark, and
then slide sub weight on scaled bar by one notch
backward per every 5g added to cartridge
weight. (In using any shell other than one
supplied, add to or deduct from cartridge weight
the difference in weight between these two
shells.)
z
Lateral balancing
If arm flows laterally to either side while inside
force canceller weight is suspended from zero
point or is removed from cartridge, slide lateral
balancer to either side to prevent arm from
flowing so. (Make sure beforehand that arm base
is set level.)
