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
You can contact our online customer service for supplementary matters

Why is the salt water truck not responding?
1. Please check whether the B15 parts are offset and dropped or not installed in place
2. Check to see if the motor gear and the wheel gear are connected, if not, it will idling and no response
3. Check to see if the motor terminals and the brine fuel cell are assembled correctly
4. If it is confirmed that the above actions are all correct, please remove the V8 engine group to see if the engine car is moving. If it can walk normally, the V8 engine is stuck due to burrs or it is not assembled in the wrong order.
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-752 Salt Water Powered Engine Car?
The GE-752 is a self-assembly, salt-water-powered engine car science toy. It combines a vehicle model, an operating engine mechanism, and a salt-water fuel cell. Once assembled, the car can move. The hands-on process introduces users to mechanical structures and green-energy power concepts.
-
Does the GE-752 Salt Water Powered Engine Car require batteries?
The GE-752 does not require conventional batteries during normal play. It uses a salt-water fuel cell for power. After one drop of salt water is added, the fuel cell generates electricity through a redox reaction, which drives the motor, gears, and wheels to move the assembled engine car.
-
What engine mechanisms can be observed with the GE-752?
The GE-752 introduces the operating concepts of V-type and horizontally opposed engines. Through model assembly, users can observe how the engine assembly works with the vehicle mechanism. Gear transmission and the salt-water fuel cell then allow the science toy to demonstrate both engine structure and green-energy propulsion.
-
What scientific principles can be learned by assembling the GE-752?
The GE-752 covers gear mechanics, capillary action, and redox reactions. Capillary action describes how liquid can move through narrow spaces. The salt-water fuel cell uses a redox reaction to generate electricity, and the gear mechanism transfers the power to drive the engine car.
-
What age is the GE-752 suitable for, and what are its assembly time and difficulty?
The GE-752 is suitable for ages 8 and up. Estimated assembly time is about 1.5 hours, and the difficulty rating is three stars. Assembly includes the engine mechanism, gears, motor terminals, salt-water fuel cell, and other sections. Users must follow the sequence and make sure each part is installed correctly.
-
Is the GE-752 Salt Water Powered Engine Car designed and manufactured in Taiwan?
Yes. The GE-752 product information states that it is designed and manufactured in Taiwan. This science toy integrates an operating engine mechanism, a salt-water fuel cell, and a gear-mechanical design. The product page lists Taiwan and China as applicable markets; check actual local availability before purchasing.
-
What should I check if the assembled GE-752 spins freely or does not respond?
First, check whether part B15 is misaligned, has fallen out, or is not fully seated. Then check whether the motor gear meshes correctly with the wheel gear; gears that do not engage may spin freely. Finally, make sure the motor terminals are properly connected to the salt-water fuel cell.
-
How can I tell whether the GE-752 V8 engine assembly is jammed?
After confirming that all other assembly checks are normal, remove the V8 engine assembly and see whether the engine car can move. If it runs normally after removal, the V8 engine assembly may be jammed by remaining burrs or by parts assembled in the wrong sequence. Recheck the burrs and assembly order.
-
How can I test the motor if the assembled GE-752 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 a troubleshooting test, not the GE-752’s normal power method. During normal use, the vehicle is powered by the salt-water fuel cell.
-
How should I clean the GE-752 salt-water fuel cell after each use?
After each use, immediately disassemble the GE-752 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.
