Confirm the operation
and switching of each
lever with the right
diagram.
Every lever turns on
when lowering and
turns off when raising.

Figure ー
Turn off the lever 1 and
lever 2 and turn on the
lever 3. Put the gauge to
the piston part and adjust
the height so that the tip
of the gauge comes to the
upper part of the piston
(but not the cylinder). Turn
the screws at both sides
equally to adjust the
height. Check the center
at times looking from the
gear side. Adjust the
height so that the shaft
comes straight from as
near the center as
possibly can.

Figure ー
Put two AA batteries in the
battery box (pay attention to
the direction!) and connect it
with the motor connecter.
Check the condition by
pushing forward the flywheel
with a finger as shown in the
Figure ー . If it moves
smoothly, the position is
almost right. If it moves
heavily, you need more
adjustment. Find the right
position until the displacer
start moving automatically by
turning the screws at both
sides little by little. (Fine
adjustment is needed. Turn
the screws less than a round
at a time.) The displacer
moves faster in proportion as
the shaft become level with
the stand. Find the place
where it moves as fast as
possible.

Figure ー
After adjusting the
position to move the
displacer faster,
disconnect the battery
box from the motor
connecter and then
connect the lamp
connecter and the motor
connecter. Then screw
and set the glass cylinder
paying attention not to
break the displacer.

Adjust the position of
the shaft of the
displacer while
pushing forward the
flywheel with a finger
so that the metallic
part at the end of the
displacer slightly
touches to the end of
the glass cylinder.

When the height is
adjusted properly,
the flywheels move
smoothly.

The displacer doesn't
move well if it is pushed
too much to the end and
crushed. The adequate
condition is to touch the
end softly.

Warning ★ Fire is used for the experiment. Use great caution to avoid
a burn and fire. Do not let a 15 or less-year-old child experiment alone.
