Installation Notes Having a hard time removing parts from the board? In the laser cutting process, in order to ensure that the parts will not fall easily during packaging and transportation, 1-2 connection points will be reserved before the parts and the motherboard, and you can use your fingers to apply a little force to move up and down (just like breaking mosquito coils when you were young) ), the part will come off. If the strength is not enough, you can use a utility knife to cut the connection point and then move it. When encountering small parts, you can use a small strip object such as the flat part of a pencil to push it off. What if a part is broken? This kind of situation is relatively rare, the hardness of the plywood is still good, if only the surface is a little split, it will not affect the assembly effect, if the part is really broken, there are remedies, such as using super glue, it is easy to break under normal circumstances More parts will be equipped to prevent irreparable situations. Inserting the shaft (toothpick) into the gear is too laborious, and not an easy job? Most of the time, you don’t need to make a lot of effort.

Slightly polish the structural part where the shaft is to be inserted. 3. Use small pliers to clamp the shaft at a suitable position, apply a little force, and insert it in a little bit. The disadvantage is that if the force is too large, the shaft will be deflated and the shape will not be smooth. Doesn't run smoothly after installation?

When removing the gear parts from the main board, the first step is to remember to grind the contact surfaces and points of the gear parts, especially the bumps that connect with the main board
