4-(6) Anti-skating Adjustment
Adjust the anti-skating force according to the cartridge
used. Turn the anti-skating knob dial to the same number
on the tracking force dial.
Set the "2" of the Knob dial to the index Arrow since the
L-A10 is provided with a spherical stylus except U.S.A.
4-(7) Pulley Height Adjustment
When the pulley has been replaced for a different fre-
quency, adjust the height of the.pulley so that the belt is
located in the middle of each section. If this is not done its
correct speeds cannot be obtained and the speed change
will not be smooth.
If the belt is in contact with the shift lever, the height of
the pulley is not correct. Loosen the set screw. and adjust
the pulley vertically. (Fig. 12)

motor shaft and turntable spindle.

turn the tracking force dial until the '0 mark is aligned
with the index line on the tonearm weight shaft.
