Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

REPLACEMENT OF CHIP COMPONENT
3.3.1 CAUTIONS (1) Avoid heating for more than 3 seconds. (2) Do not rub the electrodes and the resist parts of the pattern. (3) When removing a chip part, melt the solder adequately. (4) Do not reuse a chip part after removing it. 3.3.2 SOLDERING IRON (1) Use a high insulation soldering iron with a thin pointed end of it. (2) A 30w soldering iron is recommended for easily removing parts. 3.3.3 REPLACEMENT STEPS 1. How to remove Chip parts [Resistors, capacitors, etc.] (1) As shown in the figure, push the part with tweezers and alternately melt the solder at each end.
2. How to install Chip parts [Resistors, capacitors, etc.] (1) Apply solder to the pattern as indicated in the figure.
(2) Grasp the chip part with tweezers and place it on the solder. Then heat and melt the solder at both ends of the chip part. (2) Shift with the tweezers and remove the chip part.
[Transistors, diodes, variable resistors, etc.] [Transistors, diodes, variable resistors, etc.] (1) Apply extra solder to each lead. (1) Apply solder to the pattern as indicated in the figure. (2) Grasp the chip part with tweezers and place it on the solder. (3) First solder lead A as indicated in the figure.
