Warning

To avoid the risk of property damage, serious injury or death:

This kit should only be used by persons 12 years old and up, and only under the supervision of adults who
have familiarized themselves with the safety measures described in the kit. Keep small children and
animals away, as it contains small parts that could be swallowed. The fuel cell generates gases that are
very easily ignited. Read the instructions before use and have them ready for reference.

Battery operation instructions:

1. The removing and inserting of batteries is to be conducted by the adults only.
Unscrew the screw holding the battery pack’s cover in place using a screw driver. Once the screw is
removed open the battery pack and take out the batteries using your fingers. Do not use a metal object.
When inserting the batteries make sure that you are doing so with the correct polarity (the positive end of
the battery must match up with the “+” and the negative end of the battery must match up with the “-”
indicated on the battery pack), close the battery pack and secure its cover by tightening the screw with a
screw driver.

2. Non-rechargeable batteries are not to be recharged.

3. Different types of batteries such as rechargable, alkline and standard batteries or new and used batteries
are not to be mixed and should be used separately.

4. The battery pack cables are not to be inserted into an AC socket.

5. The supply terminals of the battery pack are not to be short-circuited.

6. The two spare red&black cables are not to be inserted into an AC socket.

7. Exhausted batteries are to be removed from the battery pack.

Fuel Cell

Connect the wheels onto the chassis of the car.
Press each wheel into the pins located on each side of the chassis until
you hear a “snapping” sound.

Insert the reversible fuel cell into the rectangular slot located on the car
chassis.

Insert the Hydrogen and Oxygen outer storage cylinders into the round

should not touch
the wheels.

Chassis

Remove the cap from the tube connected to
the oxygen side of the fuel cell. Using the
syringe, inject distilled water into the fuel cell
until the fuel cell is HALF filled with water.
*WARNING: The polymer membrane is an
important part of the proton exchange
membrane (PEM) fuel cell, it should be
prevented from drying out.
