This is the ONLY copy of this manual I could find for a realistic price. Even Panasonic could not provide me with one.
The PDF is a very good copy and it helped me diagnose and find the fault with the unit I have.
;
Very complete and well reading drawings. Documentation is essential for successful repairs.Good documentation, with all that is necessary. This manual was what I was waiting with all the information necessary for the repairing I need it for. You must buy it if you want to do repairs or simply understand how it works.

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.

Found this to be the manual included with the original packinging, was helpfull but did not give any detailed repair instructions.
5-3-2. ADJUSTING THE GUIDE ROLLER (Refer to Fig. 5-3-2 and Fig. 5-3-3.)
(1) Play the alignment tape (NTSC:VHJ-0006, PAL:VHJ0009) and check that the envelope waveform has become maximum using the tracking center. Then rotate the �assy, roller, guide� of the supply and take up sides in the counterclockwise direction to loosen them, and then tighten them alternately until the envelope waveform becomes flat. If the envelope waveform is not maximum at the tracking center, refer to section 5-3-3, and temporarily adjust the �tracking (X value)� of the �assy, head r/p ace vc�. Note: Pressing the �CHANNEL + ( )� and CHANNEL � ( ) tracking buttons together resets to the tracking center. (2) Adjust the �assy, roller guide� at the supply side. 1) Press the tracking button (channel � ( )), and check that when the envelope waveform is set to the maximum 30 to 50%, the first half of the envelope waveform is not flat. If not flat, finely adjust the �assy, roller guide� of the supply side according to the following procedure. a. If the first half of the envelope waveform is as shown in Fig. 5-3-3 (a), as the �assy, roller, guide� of the supply side is pressed excessively, loosen the �assy, roller, guide� of the supply side to set the state shown in Fig. 5-3-3 (b), tighten again until the position that the envelope waveform becomes flat. b. If the first half of the envelope waveform is a radial shape as shown in Fig. 5-3-3 (c), tightening the �assy, roller, guide� of the supply side even further will not correct the radial shape as shown in Fig. 5-3-3 (d). In some cases, the flat part will bend in. In such cases, since the state shown in Fig. 5-3-3 (c) is normal, loosen the �assy, roller, guide� of the supply side, and tighten again until the envelope waveform becomes as shown in Fig. 5-3-3 (c). 2) Check that the output of the first half of the envelope waveform is below 80% of the maximum part at the tracking center. 3) Rotate the �assy, roller, guide� of the supply side in the counterclockwise direction by 20°. (3) Adjust the �assy, roller, guide� of the take up side. 1) Press the tracking button (channel � ( )), and check that when the envelope waveform is set to the maximum 30 to 50%, the latter half of the envelope waveform becomes flat. If not flat, slightly loosen the �assy, roller, guide� of the take up side, and then slightly tighten until it becomes flat. 2) Check that the output of the latter half of the envelope waveform is maximum at the tracking center. If not maximum, finely adjust the �assy, roller, guide� of the take up side.
(4) When set to F-SEARCH � PLAY, R-SEARCH � PLAY, check that the envelope waveform does not change. 1) If the first half of the envelope waveform changes, tighten the �assy, roller, guide� of the supply side in the clockwise direction by up to 20°. 2) If the latter half of the envelope waveform changes, adjust the �assy, roller, guide� of the take up side of step (3) again.
