2) Werétommend regular cleaning of the heads and the pinch roller of the cassette deck and there are two ways of
cleaning these parts:
tl. using a cotton bud and methylated spirits.
To clean the relevant paris, you should press the ‘eject’ button so that the door is open. Ensure that the
power is switched off, then press the ‘play’ key, which will raise both heads and the pinch roller which can
then be cleaned with the cotten bud and methylated spirits.
ie using a commercial ‘head cleaning’ cassette as per the manufacturers instructions.
When carrying out this operation, please be careful not to exert tco much force on the cassette door as this may cause
damage.
Whilst it is appreciated that using a head cleaning cassette is a more convenient methad, this does tend to have a some-
what abrasive action and may increase the wear of the heads.
The cassette parts should be cleaned after approximately 25 hours use. However, it may be necessary to clean the
cassette mechanism at specific instances as some cassettes themselves have a deposit of oxide dust which may be
deposited on the relevant parts.

CASSETTE DECK MECHANISM - GENERAL MAINTENANCE
Before attempting any specific fault-finding on the cassette mechanisms, it is recommended that the
following checks and maintenance procedures be carried out.
1. R/P HEAD (Symbol 14)
Thoroughly clean the head and examine for signs of wear; replace if worn; de-magnetise.
2. PINCH-ROLLER ASSEMBLY (Symbol! 12)
Thoroughly clean, check general condition. if rubber roller is in any way distorted, replace the
assembly.
Check the tension of the Pinch-Roller Spring, the tension should be 40 to 60gm.
3. MAIN BELT (Symbol 5)
Ensure the belt is correctly located. Check that it is not stretched or worn and replace if necessary. In
any event, remove the belt and clean with methylated spirits.
4. TAKE-UP SPOOL ASSEMBLY (Symbol 9)
Check the tension of this using a cassette torque meter. The correct reading should be 40gm per cm.
A reading of between 30 and 50gm per cm may be regarded as within tolerance.
Should the reading fall below 30gm per cm, it must be adjusted to give the correct torque.
lf it cannot be adjusted it should then be replaced.
5. REWIND IDLER ASSEMBLY (Symbol! 2)
Check the tension with the cassette torque meter using the rewind function.
The torque should be 100gm per cm but a reading of between 80 and 110gm per cm may be
considered within tolerance.
If the torque falls below 80gm per cm, it should be adjusted to give the correct reading.
If it will not adjust sufficiently, it should be replaced.
6. MOTOR (Symbol! 1)
Ensure that the motor is securely mounted and that the motor rubbers are in good condition.
7. FLY-WHEEL (Symbol 6)
Check that the Fly-wheel spindle is not worn or bent and that it is securely seated in its bearing.
8. INTERNAL MECHANISM
After prolonged use, the internal mechanism will normally contain substantial deposits of oxide dust.
Ensure that these are thoroughly cleaned.
There are no places on either mechanism which require any oil or grease and the application of any such
lubrication is likely to seriously harm the internal workings of the mechanism.
