If you are blowing up when you clamp on a chemical, gauge the closeness of the claw to have it close completely on the chemical. It depends on the sixe of the chemical.
As for getting to a chemical, use the graph line to center the pole of the claw on the chemical. You can also check the size of the claw if it will touch adjacent chemicals using the grsph line.
As for placing it in the bin when there's a chemical close by - move the claw with chemical to one side of the bin. Enter and when completlely inside, move a bit to the center to get the claw to open. Then to remove it from the bin, move it to the side again and pull it out.
As for dropping the chemical inside the bin, be sure that the claw is completely inside the bin.
