If you have built at least one Gunpla, you will recognize these icons as they are all over the construction manual. Non-Japanese-speaking (or –reading for that matter) folks like me, could only try and decipher these icons. Although Bandai’s construction manuals are easy to follow—even without any reading involved—it is still useful to know what these icons stand for.
Bandai’s early Gunpla kits require the use of plastic cement or glue. Although today’s kits are snap-built, you may still see this icon in a few construction manuals.
Attach Part to Opposite Side
Attach Identical Parts to Each Side
Do Not Over-Tighten Screw
Some Gunpla kits—usually PGs—require screws. This icon warns you not to over-tighten the screw as doing so can crack the plastic and damage the part.
Also Move the Other Side
RG frames oftentimes require loosening or moving a part into position. This icon tells you to also move the opposite side of a part/section.
Some parts may have nubs or stumps that should be removed. Remember to only cut parts that are indicated by this icon. Otherwise, stick with cutting parts from the runner gates.
Construction manuals provide step-by-step instructions that should be strictly followed. Complete any section that is accompanied by this icon first before you proceed to any other assembly.
This icon is the opposite of the above icon. This indicates that the section should be assembled after one or a series of assemblies have been completed.
You can usually see this icon when assembling multiple parts/sections such as arms, legs, funnels, wings, etc. The value indicates the number of parts/sections you must complete.
This icon simply tells you to rotate a part to a specific direction as well as how many degrees it should be rotated.
Mind the Orientation
Some kits include alternative parts. Choose the part that you prefer and attach it. This usually solves the mystery of additional parts that are left over from your kit.
