Toys not running smoothly?
Usually the operation is not smooth because the burrs are not trimmed cleanly. Check whether the burrs of the parts are completely cut according to the instructions.
Parts are missing or the part board is broken or broken during disassembly and assembly

Why is the salt water truck not responding?
1. Check to see if the motor gear and the wheel gear are connected, if not, it will idling and no response
2. Check to see if the motor terminals and the brine fuel cell are assembled correctly
How to test assembly condition without wasting salt water batteries?
After the assembly is completed, you can use a 1.5V AAA battery or AAA battery to connect the motor terminals to test whether it can work.
How to care for a saltwater battery pack?
After each play, please disassemble the salt water battery immediately, clean the magnesium alloy sheet non-woven fabric and black air electrode with clean water, and dry it separately after cleaning to avoid oxidation under prolonged contact.

What is the Pro’sKit GE-754 Salt Water Powered Off-Road Vehicle?
The GE-754 is a self-assembly, salt-water-powered off-road vehicle science toy. After building the model mechanism, add just one drop of salt water so the salt-water fuel cell can generate power and drive the vehicle. Assembly and play introduce concepts related to gear mechanics and green energy.
-
Does the GE-754 Salt Water Powered Off-Road Vehicle require batteries?
The GE-754 does not require conventional batteries during normal play. It uses a salt-water fuel cell as its power source. After one drop of salt water is added, the fuel cell generates electricity through a redox reaction, which drives the motor and gears to move the vehicle. This provides a practical way to observe an alternative-energy application.
-
How long can the GE-754 run on one drop of salt water?
After one drop of salt water is added, the GE-754 can run for about 15 minutes. Before starting, make sure the motor gear meshes correctly with the wheel gear and that the motor terminals are properly connected to the salt-water fuel cell so the generated electricity can drive the vehicle.
-
What scientific principles can be learned by assembling the GE-754?
The GE-754 covers gear mechanics, capillary action, and redox reactions. Capillary action describes how liquid can move through narrow spaces, while the salt-water fuel cell uses a redox reaction to generate electricity. The gear mechanism then transfers power to move the assembled off-road vehicle.
-
What age is the GE-754 suitable for, how long does assembly take, and how difficult is it?
The GE-754 is suitable for ages 8 and up. Estimated assembly time is about 1 hour, and the difficulty rating is two stars. It is categorized as an entry-level model. Users assemble the model mechanism, motor gear, wheel gear, salt-water fuel cell, and other sections, taking care that all parts connect correctly.
-
Is the GE-754 Salt Water Powered Off-Road Vehicle designed and manufactured in Taiwan?
Yes. The GE-754 product information states that it is designed and manufactured in Taiwan. This science toy combines off-road vehicle assembly, a salt-water fuel cell, and a gear mechanism. The product page lists Taiwan and China as applicable markets; check local availability and packaging information before purchasing.
-
Why might the assembled GE-754 bind or operate unevenly?
A common reason for uneven GE-754 operation is that burrs have not been trimmed completely from the parts. Check each assembled part and remove any remaining burrs so excess plastic does not interfere with the mechanism. If the problem persists, contact Pro’sKit online customer service about replacement parts.
-
What should I check if the GE-754 motor turns but the vehicle does not respond?
If the GE-754 motor spins freely or the vehicle does not respond, first check whether the motor gear meshes correctly with the wheel gear. If they do not engage, the motor may spin without driving the wheels. Then check that the motor terminals are properly connected to the salt-water fuel cell.
-
How can I test the motor if the assembled GE-754 does not move?
After assembly, connect one 1.5 V size 3 or size 4 battery to the motor terminals to test whether the motor operates. This is only a troubleshooting test and is not the GE-754’s normal power method. During normal use, the vehicle is powered by the salt-water fuel cell.
-
How should I clean the GE-754 salt-water fuel cell after each use?
After each use, immediately disassemble the GE-754 salt-water fuel cell. Rinse the magnesium-alloy plate, nonwoven fabric, and black air cathode with clean water. Then separate the parts and let them air-dry in the shade. Avoid leaving the parts assembled and in contact for an extended period to reduce the effects of continued oxidation.
