MAINTENANCE
1.
There are no critical adjustments or need for ‘tweak’ and only very little maintenance.
Clean the drive belt occasionally by drawing it through a piece of soft tissue or linen
moistened with lighter fuel. The same material may be used to clean the periphery of the
motor and driven pulleys. The main bearing is lubricated for life.
2.
Having sintered bronze bearings the motor requires minimal lubrication. One drop of oil
only in one year is sufficient and should not be exceeded. Remove the platter and drive
belt. Apply one drop of 1287 oil from the syringe at the point indicated on top of the
motor. Choose a time when the turntable will not be used for some hours so that the oil
can find its way down to the lower bearing. After this time check that there is no oil on
the motor pulley and replace the drive belt and platter. For cleaning the platter should be
removed from the turntable whilst its surface is sponged with a soft cloth using warm
water and washing-up liquid, followed by warm water only then a dry towel.
3.
The suspension dashpots automatically seal when the sub-chassis is locked down and do
not require maintenance.
4.
Replace the drive belt after 1000 hours use. A replacement (Part No. 1100) is available
from SME Limited.
5.
The life of the suspension bands will depend on climatic conditions. If eventually they
should stretch beyond further adjustment, replacements (Part No. 1020) are available from
SME Limited.
6.
Changing the bands is simple and may even be done while a record is playing ! Two spare
bands are provided in case of accidental damage. Unscrew and remove the upper gallery
cover from the top of the column and lift off the lower gallery cover. Remove the old
band and replace the new one over the anchorage studs. Replace the covers and re-check
the suspension height with the gauge.
7.
There are no user-serviceable parts inside the control unit. A 500 milli-amp fuse is
accessible beneath the mains input socket. Its replacement should only be undertaken by
qualified service personnel.

TRANSIT PRECAUTIONS
The Model 30/12 can be safely transported
SUBJECT ABSOLUTELY TO THE FOLLOWING PRECAUTIONS:
Short journeys by car: remove the platter, disengage the drive belt from the motor pulley,
back off the motor height adjustment and replace the motor transit screw. Lock down the
suspension. Screw down the four driven pulley transit screws lightly and evenly, just enough
to prevent the pulley rotating. The turntable itself is best placed on the floor of the car in front
of the passenger seat. The platter and other items can be stowed elsewhere provided they are
carefully protected. For all other transportation purposes the original packing case and
materials must be used.
