I want to give you a real heads-up for your desire to enable such people as I to acquire the information I need to maintain the older types of equipment such as this Akai HXA351W. You do a swell job with all the processes you have to perform so I can have a legible, thus usable
document which does not send me crazy trying to figure out the blurry text of a bad copy.
Very well done, Thomas.

This manual is very well presented and after printing out looks about as close to an original as I think you can get. The quality is second to none.
The content of the manual is comprehensive and I think it would be well suited to an audio repair professional which I'm not but I did find it very informative and helpful.
The cost of the manual is more than covered by the money I'll save when I change the keep memory battery now I have the relavant info.
Very pleased with my purchase and can recommend it wholeheartedly as I can other manuals I've downloaded from this site.

COMPONENT REPLACEMENT AND ADJUSTMENT
MAGNETRON REMOVAL
1. CARRY OUT 3D CHECKS. 2. Remove the two (2) screw holding the chassis support to the oven cavity and the magnetron. 3. Disconnect the H.V. wire B and filament lead of the transformer from the magnetron. 4. Release the chassis support from the oven cavity. 5. Move the air intake duct to left. 6. Remove the air deflector A from the magnetron. 7. Carefully remove two (2) screws holding magnetron to waveguide, when removing the screws hold the magnetron to prevent it from falling. 8. Remove the magnetron from the waveguide with care so the magnetron antenna is not hit by any metal object around the antenna. 9. Remove the magnetron cushion from the magnetron. CAUTION: WHEN REPLACING THE MAGNETRON, BE SURE THE R.F. GASKET IS IN PLACE AND THE MAGNETRON MOUNTING SCREWS ARE TIGHTENED SECURELY.
FAN MOTOR REPLACEMENT REMOVAL
1. CARRY OUT 3D CHECKS. 2. Remove the one (1) screw holding the noise filter to the chassis support. 3. Release the noise filter from the tabs of the fan duct. 4. Disconnect the wire leads from the fan motor. 5. Remove the one (1) screw holding the fan duct to the oven cavity back plate. 6. Remove the fan duct from the oven. 7. Remove the fan blade from the fan motor shaft according to the following procedure. 1) Hold the edge of the rotor of the fan motor by using a pair of groove joint pliers. CAUTION: � Make sure that any pieces do not enter the gap between the rotor and the starter of the fan motor. Because the rotor is easy to be shaven by pliers and metal pieces may be produced. � Do not let the pliers touch the coil of the fan motor because the coil may be cut or damaged. � Do not distort the bracket by touching with the pliers. 2) Remove the fan blade from the shaft of the fan motor by pulling and rotating the fan blade with your hand. 3) Now, the fan blade will be free. CAUTION: � Do not use this removed fan blade again. Because the hole (for shaft) of it may become bigger than a standard one. 8. Now, the fan motor is free.
