A modelling kit will usually have symbols in their instruction manual right next to the illustration. Their purpose is to make it easier for modellers to understand what has to be done in this step as well as to save on space on the part of the manufacturer in having to type the instruction in the manual.
Most of the symbols in Bandai Model model kit manuals are generic to each other. Which is convenient because if you've seen one then you've seen them all and you can be assured that they practically mean the same thing. The symbols meanings are usually found at the bottom of the page for the newer model kits, while on the older kits its found in the first few pages.
The downside is that they are written in Japanese. But fear not because this post will give an English translation of what those symbols mean.
Part to be glued - these parts should be glued together. For a Bandai kit this is usually rare nowadays because the recent models have been designed to just snap together. On the rare occasion that parts have to be glued together regular scale model glue (like Tamiya Plastic Cement, Revell Contact Cement). I myself prefer Super Glue to stick parts together, except in the case of clear parts as the super glue might fog it up.
Metallic Sticker Number - this is the sticker number of the sticker from the sticker sheet to be sticked on at that location.
Decal Number - this is the decal number of the decal from the decal sheet which will go that location.
Part to be installed on the opposite side. Usually there will be 2 part numbers next to this symbol. Meaning that one will go to this side while the other will be placed on the opposite side.
Similar part will be installed on the opposite side. This symbol will have one part number adjacent to it and this means that another one like this will be installed on the opposite side.
Pay attention to the orientation/direction of the parts during assembly, when installing the part refer carefully to the illustration on the manual so that it won't be installed wrong.
Be Careful to not tighten it too much. This usually refers to the screws that come with the kit. Overtightening the screw can lead to the plastic stripping or screw head off.
Cut this part off. This usually refers to the excess gates of the plate (like undergates). Look carefully at the instructions so that you don't make the mistake of cutting off the wrong part.
This procedure has to be repeated "x" number of times because of the number of similar parts involved. So it also means you have to build "x" number of pieces of the same part. I usually see this in missile and fin funnel parts of the Bandai model kit which have a lot of them.
Connect this part first - this usually means to install this part first, usually because it is a key part of the model or is located within the recess of the model.
Connect this part after the rest of the other parts - this usually means to install this part last.
Number of degrees the part will be rotated opposite from its current position. In this case, it is to turn this part 180 degrees.
Your choice to choose which part you want to install. Basically this tells you that there is the choice to build this another way. One common example of this in Gundam kits are with the beam sabers, where you are given the choice to build it with either the beam saber on or just the hilt. Another common example in Gundam model kits is that some kits can be assembled as the cannon-fodder variant or the commander type, depending on the parts you have chosen when you see this symbol.
Opposite side will also move the same direction - this means to move the part in the other side in the same direction.
(Some other) points to take note of or be aware of - the double quote looking symbols mean to take note of this part
One other symbol that you will usually find in the manual are numbers placed inside diamonds. This is usually a sequence guide for you to follow for that particular step. If we follow the illustration below as an example. The illustration tells us to first attach part A9, then fold down the wings then at step 3 pull out the wings then step 4 tells us to attach d13 and at the opposite side, d12
