Maintenance
To get long, trouble-free service, maintenance is important. Do not forget cleaning and demagnetizing.
Cleaning
After long, the heads and tape part – capstan, pinch roller, etc. – will become dirty with dust or magnetize particles. Dirty heads cause imperfect erasing or hogj frequency drop-off. A dirty capstan and pinch roller will cause unstable tape speed, leading to increased wow and flutter. Always keep them clean by following the procedure below.
1. Heads
- 1) Remove the front transparent cover.
- 2) Press the EJECT lever to open the cassette door.
- 3) Use the head cleaning stick to wipe the surface where the tape comes into contact with the head.
(It is effective to moisten the cotton with alcohol.)
2. Pinch roller and capstan
Perform the cleaning in the same manner as for the heads.
* Do not use any cleaner besides alcohol or a specifically prepared tape head cleaning solution.
3. Cleaning the cabinet and panel
Wipe the cabinet and panel clean with a soft cloth dipped in a neutral cleaner. Do not use thinner, benzine, alcohol or other strong slovents, as these will cause damage to the surface finish of the cabinet and panel.
Demagnetizing
The heads are made from a material resistant to magnetization, but after long use they may become magnetized. A magnet brough into their vicinity can magnetize the heads, causing excess noise. If noise seems to have increased, demagnetize the heads with a head demagnetizer through the following procedure.
- 1. Turn the POWER switch OFF.
- 2. Wrap the tip of the demagnetizer with vinyl tape or soft cloth so as not to damage the head surface. Switch on the demagnetizer and bring it close to the head.
- Move the tip of the demagnetizer slowly first to the left and right, then up and down in front of the head. Gradually move it away from the head and switch it off at a distance of more than 30 cm (12").
- 4. The rase head need not be demagnetized. The capstan shaft and tape guide should be demagnetized in the same way as the record/playback head.
- * Do not bring a magnetized metallic object (a screwdriver. for example) near the head as this will increase noise.
Oiling
Feed one or two drops of machine oil to the rewind roller shaft, pinch roller shaft and magnet pulley shaft once or twice a year under normal conditions of use.
Avoid oiling them excessively, or rotation may become irregular because of oil splashes.

[II] Adjustment and repair of the mechanism
TROUBLESHOOTING HINTS
1. Azimuth adjustment and head replacement
- 1) Remove the wires of the control switches from the wire clamps after having removed the top panel.
- Remove the two screws positioned below the control switches (on the bottom of the deck) and pull the control section forwards.
- With the control section pulled out, azimuth adjustment and/or head replacement can be performed. With the JVC cassette deck series of KD-A6, KD-A5 and KD-A8 models, the adjustment or replacement can be performed more easily than with conventional cassette decks which require removal of the entire mechanical section for the adjustments and/or replacements.
2. Tape-to-head contact adjustment
- 1) Turn the adjusting screw for aligning the erase head until it stops. Then, turn the screw in the reverse direction by 225° (a 5/8 revolution).
- 2) Check the tape-to-head contact using a C-120 tape having pads.
- 3) Check it again with a Metal tape.
Checking method: Record a 400 Hz or 1 kHz signal with 0 VU + 20 dB. Erase the recording. Check if the erasing is satisfactorily performed.
4) After adjustment, apply screw bond on the adjusting screw to prevent its loosening.
