Connect the refueling station’s output valve to the car’s input valve turning clockwise while gently pressing in. Make 

sure the switch beneath the car's chassis is at the "off" position. 

Using the solar panel, make sure it is placed in direct sunlight. It will take about 10 minutes in strong sun light for the 

car's tank to fill up with hydrogen using the standard solar panel included. Keep the refueling station powered until the 

balloon inside the hydrogen storage cylinder is full. Once the operation is complete and the balloon is full, make sure 

you turn the refueling station to the "off" position.

Alternative: It will take at least 1 minute for the balloon to fill with hydrogen using the "DC" power switch if the batteries 

are new.

TIP: After 20 minutes of continuous use, turn the Hydrogen Station off, and let it rest for at least 10 minutes before 

starting it again.

Warning: Continuous operation of the Hydrogen Station will damage it permanently.

The hydrogen storage tank is now full and the H-racer is ready to race! To run the car, find a smooth, flat surface free 

of obstacles. Turn the switch located beneath the car's chassis to the "on" position, place it on the ground and watch 

the car go!

 

It is estimated that on a full tank and after a number of warm-up runs the H-racer will run for up to 3 minutes.

To purge the complete 

fuel cell power system, 

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. 

Disconnect the syringe 

connector valve from the 

additional input valve attached to the 

refueling station by turning it anti-clockwise, 

allowing the connector to pop out. Your storage 

tank is now purged and ready to receive hydrogen 

from the refueling station.
