firmly down until all the locks have been operated as damage could occur if one end lifts
before the other.

SETTING UP
1.
The motor is mounted on three height adjustment screws, the points of which nest in
compliant cups in the base. For transit purposes these screws have been backed off clear
of the compliant cups and the motor secured to the base with the Motor Transit Screw.
This must be removed using the long leg of the 2.5A/F hexagon wrench as a lever through
the cross hole in the head of the screw. The ends of the height setting gauge (1084) are
marked A and B. Re-engage the points of the height adjustment screws with the compliant
cups and adjust so that end B of the gauge is just admitted near each screw in turn
between the underside of the motor and the surface of the base.
2.
For transit the main bearing is off-loaded by the four pulley transit screws. These are
captive and should be turned anti- clockwise with the 3mm A/F hexagon wrench until
they stop. Ensure the wrench is fully engaged to avoid damage to the transit screw socket.
3.
Unpack the drive belt and place it over the driven pulley. Press it down as far as the
flange, ensuring that it is free from twists, then stretch it over the motor pulley. The
pulleys will be out of alignment without the weight of the platter so rotation must not take
place until it has been fitted.
4.
Remove and unpack the platter from the bottom section of the case . Place it carefully and
squarely over the turntable spindle and lower it gently down until it rests on the driven
pulley, having first ensured that both mating surfaces are clean. Rotate the platter slowly
by hand to position the belt on the pulleys.
WARNING:
Please avoid handling or anything
that might scratch the turntable platter. The material is as delicate as a record itself and
very easily damaged.
5.
The base should now be levelled by rotating the supporting feet until the bubble and
reference ring of the spirit level are concentric. The feet will turn more readily if the
corresponding corner of the base is lifted slightly at the same time.
6.
The Model 30/12 is intended to receive an SME Series V-12 precision pick-up arm and is
supplied with the arm mounting plinth installed to provide the correct positional
alignment to accommodate it. However, other SME precision pick-up arms such as the
Series V, Series IV and Series 300 Model 309, may also be accommodated by reversing
the position of the arm mounting plinth.
This may be achieved as follows:
First remove the four M5 socket cap head fixing screws attaching the arm mount plinth to
the turntable sub-chassis, using the 4mm A/F hexagon wrench provided, then lift it up,
rotate it half a turn (180
0
) and set it back down again in position ensuring the screw holes
are in line. Replace the fixing screws and retighten.
7.
The Model 30/12 is provided with a non-standard 1.8M (6 ft) audio lead, the plug contacts
of which have been rotated through ninety degrees so the cable can leave the arm
vertically downwards.
8.
If you are not already familiar with the Series V-12 arm, carefully study its instruction
book at this point. Fit the cartridge of your choice and feed the audio lead up through the
cut-out in the arm mounting plinth. Do not over-tighten the four M5 x 30 socket cap
screws holding the arm mounting plinth to the sub-chassis. The intended interface will be
obtained if the screws are tightened holding the short leg of the hexagon wrench. Plug the
lead into the arm, which should now be secured to the arm mounting plinth using the four
