necessary. Check from time to time by removing platter and drive belt and spinning the
driven pulley. If it is stiff to turn and stops very quickly the bearing is too tight, if it
continues to spin for a very long time the bearing is too loose, somewhere between these
two conditions is correct.
Adjustment is carried out as follows:
Invert the base and sub-chassis assembly keeping the spindle clear of the table with some
judiciously placed books. At the centre of the base will be seen the bottom bearing cap
which is on a fine screw thread. Before leaving the factory this was scribed with a radial
line so that its adjustment can be positively identified, and we stress here that when
re-adjusting rotation should never be more than the thickness of this line at one time
before reassessment. To effect movement the cap is turned by passing a small
screwdriver blade through the cross hole in it in the manner of a tommy-bar. Use both
hands for maximum control moving it slowly with gentle firmness. The golden rule is ‘a
very little at a time’ as the bearing could be severely damaged by over-tightening and
failure to observe these instructions would not be covered by warranty. Clockwise
rotation tightens the bearing anti-clockwise rotation releases it. Do not alter the factory
adjustment unless there is real evidence of need.
4. Spindle lubrication is also recommended after 1000 hours use or two years. With the
turntable inverted as for bearing adjustment take out the small screw near the centre of
the bearing cap and insert just one drop of oil, from the syringe of lubricating oil. Do not
exceed this. Replace the screw and tighten.
5. 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 and then a dry towel.
6. Replace the drive belt after 1000 hours use or two years. A replacement (Part No. 1100)
is available from SME Limited.
7. There are no user-serviceable parts inside the power supply unit. A 500 milli-amp fuse is
located below the mains socket, its replacement should only be undertaken by qualified
service personnel.
26. TRANSIT PRECAUTIONS
1. The Model 10 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,
and replace the transit screw (see page 7). 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.
