pneumatic low pressure

[cmontene]

Hello,
I am in Bogota (8360 ft) and fly an MTOsport 2010. Here in Colombia there are very few autogyros (I think no more than 4 !). So it is hard to find tecnical support.
Need help with this one: To increase pressure in break position, I had to put it in flight mode, back trim until 2psi pressure, move it to break, and then the pressure will go up to 7psi (was that normal?).
But now the pressure will not go above 4psi. Any ideas how to identify the problem? Thanks!

Pneumatic systems just need to be taken a step/part at a time.

There are valves, joints, hoses and cylinders.

Take it a component at a time.

Figure out what it does and how it does it.

Find a way to measure it and move on to the next thing.

Generally a component works or it doesn’t.

Don’t confuse yourself with workarounds and trying to understand the logic.

Find what is not working correctly and replace it.

Good luck!

Correction: Those are bar. Not psi.

The units of measure make no difference.
It reads like it is either the pump or a leak that opens up under pressure either in the valve or in the line.
Keep it simple.

A smoke generator is very helpful for finding leaks....

Does anyone have a circuit diagram for the 2010 MTOsport pneumatic system?

This can be of help, I hope...
