5. Refueling and operation
H-racer
To refuel the with hydrogen you will need the
syringe with valve (part F), and the additional input valve (part D) with rubber tubing (part G).

The 's power system only accepts hydrogen as its fuel. If other gases are present, the fuel
cell cannot operate and the car will not move. For optimal performance of the
has to be purged of all the gases within the car and station.
Step 1
Make sure the switches underneath the car's chassis and on the
side of the Hydrogen Station are at the "off" position. Connect
the refueling station's output valve to the car's input valve by
firmly pressing the syringe's connector valve into the car's input
valve, and turning the output valve clockwise.
simultaneously
(see 1A & 1B).
Once the two valves are connected you can let go of the output
valve as both valves are now locked into position.
TIP: The refueling station's output valve is fragile. If you do not
continue to "press in" while you are turning the output valve
clockwise, you will risk breaking the output valve.

Step 2
Ensuring the refueling station's output valve remains connected to the car, open the small, grey
pressure valve on the side of the refueling station (see 2A & 2B).
Step 3
Connect the third flexible tubes (part G) to the nozzle located on the additional input valve (part D)
(see Step 2 of Assembly Instructions).
Step 4
Holding the pressure valve open, insert the open end of the rubber tube onto the little nozzle inside
the grey pressure valve (see 4A).

Step 5
Find the gas purging syringe with connector valve
(part F). Push all the air out of the syringe, by
pushing the inner container of the syringe into its
outer container. In the same way as connecting the
refueling station's output valve to the car's input
valve, now connect the syringe's connector valve

connected to the refueling station (see 5A).
TIP: The syringe's connector valve is fragile. If you
do not continue to "press in" while you are turning the
syringe connector valve clockwise, you will risk
breaking the connector valve.
To purge the complete fuel cell power system, pull
the inner container of the syringe towards you while
watching the balloon inside the gas storage tank
carefully. Make sure you remove all the air out of the
balloon by pulling on the syringe. Stop pulling on the
syringe once all the air is removed from the balloon
(see 5B & 5C).
TIP: To avoid air coming back into the balloon, stop pulling on the syringe once the balloon is empty -
do not go too far, as this will cause air suction once you disconnect. Do not let the air be pulled back
inside, the objective is to eliminate as much air as possible from the car's refueling system.
Disconnect the syringe connector valve from the additional input valve attached to the refueling
station by turning it anti-clockwise quickly and lightly, allowing the connector to pop out. Your storage
tank is now purged and ready to receive hydrogen from the refueling station.

Step 6
Activate the refueling station by switching it to the "DC" position or the "☼" position (switch located

behind the ). You can switch to "DC" if you have added the alkaline batteries
inside the refueling station or the "☼" position if your refueling station is connected to its solar panel.
If you are using a solar panel, make sure it is facing strong and direct sunlight. If it is cloudy or if it is
night time, you will need to switch to "DC".
