Check that tension spring (Ill) is anchored to the unit
plate and support bracket assembly (7). When the
operating control is turned to "Manual". spring (I21)
should pull the support bracket assembly into engage-
ment with motor pulley. If it does not. and the tapered
pin beneath the support bracket assembly (7) is not
found to be bent, replace spring (IZI).

Wheel (95) should engage motor pulley firmly when
the unit is switched on and retract when switched off.
Lubricate the two pivot spindles on the support bracket
assembly if they appear to be tight. Replace the support
bracket mechanism if damaged.

Remove plug (49) from motor (73). switch on and check
with voltmeter. If no reading. check back to source out-
let. looking for loose connections. faulty switch contacts.
etc.

Remove plug (49) from motor (73) to check continuity
of coil with an ohm-meter. Replace motor if necessary.
(Two plugs and two coils on 4-pole motor.)

If the rotor shaft is tight. tap the motor body with a
small block of wood such as a screwdriver handle to
realign bearings. Use only fine machine oil such as used
for sewing machines on these hearings.

Set as described under "Maintenance" and Diagram 18.

Check motor (73) intermediate wheel (95) and turntable
bearings for free running. See lubrication section under
Maintenance".

A 60Hz pulley will run the unit slowly on 50Hz supply.
(The pulley base diameter is smaller than the 78 rev/min
pulley step for SOHz and larger for 60Hz as identifica-
tion).

Record speed varies (Wow

7 and 8.

It is not advisable to play badly warped or dished
records automatically, although small strips of adhesive
tape on their labels may help adjacent records to key
together.

Replace motor (73).

If running the unit for a while does not cure the fault,
replace the wheel (95). (Do not switch the unit off from
the power supply before it has stopped automatically,
as the unretracted wheel (95) may form flats.)
