 ;
The manual was of good quality with high resolution schematic diagrams.
;
The manual was very clear and contained all the information I was looking for. My dishwasher is working again because of this servicemanual!
;
Quality scan, great manual. I solved my problem with this manual.
 ;
The AKAI 1720 model reel to reel tape recorder described in this Manual is quite an old unit - circa late 1960's. As a consequence, the description of the mechanical details - and adjustments thereof - is quite critical. The manual does this quite well. The schematics are also well presented and have detailed PCB overlays. Probably the only negative is that some half-tone detail has been lost from the original manual as it has been scanned in simple B&W.
;
Perfect source for service manuals: fast and professional transaction; high quality, perfect readable and largely scaleable PDF; complete schemes, diagrams and spare part list. Tnx a lot, cu again!!!!
CHAPTER 5 TROUBLESHOOTING
Points to Note When Taking Measurements 1. Be sure that the three separation belts are in contact with the test strip. 2. Be sure that the test strip is pulled straight along the separation belt (Figure 5-131). 3. Be sure that measurements are taken when the rear end of the test strip and the rear end of the original tray are flush (Figure 5-136).

Figure 5-136 Measuring the Feeding Power (front) 7) Open the upper cover of the DADF to end measurement. 8) Loosen the lock nut 1 used to keep the front, and turn the adjusting screw 2 until the feeding power is as indicated. Then, tighten the lock nut 1.
Note: As a guide, try to limit the difference in feeding power between front and rear.

Table 5-110 Adjusting Screw and Feeding Power 9) Likewise, adjust the feeding power at the rear. 10) Measure the feeding power at front and rear once again. If the measurements are as indicated, firmly tighten the lock nut and glue it in place. Otherwise, make adjustments once again.
