You can pull the
9
b
assembled water
wheel off the axle
and stick it back
on again. You
may have
to do this if
the paddle
direction is
wrong.
When removing the water wheel, press the two
gear wheels tightly together so that the paddles
don’t fall out. Then carefully remove the axle.
Be careful not to twist the water wheel disks and
gears, or to crush them.
If the water wheel falls apart, you will have to
reassemble it with the instructions on page 6.
