Hydraulic fluid level: The rollbar top is powered by a hydraulic system, so make sure that the fluid level is full. If the fluid level is low, it can cause the top to stop working properly.
Hydraulic pump: The hydraulic pump is responsible for circulating the fluid in the system. If the pump is not working properly, it can cause the top to stop working.
Valves: The valves in the system control the flow of fluid. If the valves are not working properly, it can cause the top to stop working.
Electrical connections: The rollbar top is also controlled by a number of electrical components, such as switches and sensors. If any of these components are not working properly, it can cause the top to stop working.
If you are not sure how to check these things, you should take your car to a qualified mechanic to have it diagnosed.
