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!!!!
2.2.7 Checkup and adjustment of mechanism phase
<Rotary encoder> Set the �s� of the rotary part at the tapped hole as shown in the figure.
<Connect gear> (Note 2) Set the connect gear so that its locating hole meets the hole on the main deck assembly.
<Worm wheel> (Note 2) Set the worm wheel so that its locating hole meets the hole on the main deck assembly.
Note 1 <Main cam gear /Brake control plate> After fitting the main cam\ gear and brake control plat together,set them together so that their locating holes meet the hole on the main \ deck assembly.
<Connect gear 2> (Note 2) Set the connect gear 2 so that its locating hole meets the hole on the main deck assembly.
<Sub cam gear> Set the sub cam gear so that its locating hole meets the hole on the main deck assembly. This state represents that the mechanism is in the EJECT mode, which is the �mechanism assembly mode�.
Note 1: Since the connect gear 2 is tightly fixed to the main deck by caulking, adjust its phase with the connect gear and sub cam gear.
Note 2: The part that needs phase adjustment by the hole on the main deck assembly must exactly be set as the specified phase. There is a fear that some part is installed in a wrong phase because assembling of the mechanism is automated. If so, set every part in the correct phase whenever the mechanism is reassembled.
