You mean those two rows of symbols? I'm pretty sure most
people ignore those anyway... (they're not necessary most of
the time since the parts only fit together a certain
way).
Here are their meanings from left to right:
1st row:
1-1 - Glue together
1-2 - Indicator for which marking seal to use (in Katakana)
1-3 - Indicator for which decal to use (in Roman Alphabet)
1-4 - Attach parts in the opposite direction on both sides
1-5 - Attach part in the same direction both sides
1-6 - Caution: note the direction of the part
1-7 - Caution: do not over tighten the screw
2nd row:
2-1 - Cut this part
2-2 - Make the same part the number of times indicated inside
the box
2-3 - Assemble this part first
2-4 - Assmeble this part afterwards
2-5 - Turn the part according to the degrees indicated in the
box
2-6 - Choose one of the parts to assemble first
2-7 - Move both parts the same way in opposite directions
