Excellent service manual includes everything is need to repair this radio-caseete, how to disassemble, wiring diagram, all , waiting time until the download was only a few hours. I'm going to buy service manuals from here, are cheap and very good.Thank you.
Good service manual,i saved from scrapping this deck,is now fully functional.Thanks.
Found this to be the manual included with the original packinging, was helpfull but did not give any detailed repair instructions.
Complete service manual, was very helpful in repairing this tapedeck.Thanks.
The service manual was a copy of the original from Wirlpool. The quality was good, all neccecary information was available including the service-codenumbers, so I could order the right part to be replaced for repair.
Downloding was no probem after the payment.
Thanks for the service!

1. Clean the following parts with a denatured-alcohol-moistened swab : playback head pinch roller capstan rubber belt 2. Demagnetize the playback head using a head demagnetizer. 3. Do not use a magnetized screwdriver for adjustments. 4. After the adjustments, apply suitable locking compound to the parts adjusted. 5. The adjustments should be performed with the rated power supply voltage (2.5V) unless otherwise noted.
