6.1. RC system troubleshooting.
The following list of checks can be used for determining problems in case the RC
system does not function properly:
1. Study the instructions in this manual.
2. Visually check all air hoses and connections to ensure that there are no air leaks.
3. Ensure that the safety and drain valve are closed.

— when the key is depressed no air should come out of the handle.
