1. The car does not move or runs slowly:

a. Re-insert the batteries in the remote control or remove the used batteries and insert new batteries into the remote 

control with correct polarity. 

b. Turn the switch to “on” position, if it is in the “off” or “warm up” position.

c. Activate the fuel cell by turning the switch to "warm up" position. The light under the gas storage cylinder will not 

flash. Leave the car until it fully consumes the hydrogen and activates the fuel cell. Turn the switch to the "on" position. 

The light under the gas storage cylinder will flash.

d. Press the purging valve to purge the remaining gases and then charge the hydrogen storage balloon fully again.

e. Make sure the wheels are free of obstacles. Point the remote control directly at the car.

2. The car runs for a short time:

a. Charge the car until the balloon in the tank swells fully along the wall of the tank.

b. Activate the fuel cell again or prolong the activation process as in 1.c.

c. Charge the car, press the purging valve to purge it, and then re-charge the car again until it is fully charged.

3.The green LED lights do not flash and/or no bubbles appear in the Hydrogen Station’s water tank:

a. If you are using solar panels, make sure the solar panel is in direct sunlight. The standard solar cell included with 

the Hydrogen Station will fill the H-racer 2.0 after at least 10 minutes in strong sunlight. Also, check whether the cable 

connections are correct.

b. If you are using the "ON" battery power option and bubbles are appearing slowly the batteries may be out of power. 

Please replace the alkaline batteries inside the Hydrogen Station with new alkaline batteries.

c. If the bubbles are appearing slowly or if there are no bubbles in the Hydrogen Station’s water tank, first add water 

to the water tank filling it to the top and then position the tube connected to the syringe at the top left outlet from the 

tubing where the bubbles should be released. Pull the inner plunge of the syringe towards you. Empty the water in the 

syringe into the water tank. Repeat this step several times until you see the bubbles come out from the top left outlet. 

4. The balloon inside the car's storage tank does not fill up:

a. Make sure all the tubes inside the car are well connected and that the output valve of the hydrogen station is well 

connected to the input valve of the car (press the output valve tightly into the input valve). You may want to unplug 

and plug the connectors once more to be sure.

b. If all connections are correct and bubbles are released, and the balloon still does not fill up - your H-racer 2.0 

refueling system may be damaged due to improper use. Do not attempt to repair or fix your H-racer 2.0, contact 

support@horizonfuelcell.com for assistance.

c. Remove the used batteries and insert new ones with the correct polarity.
