If your Yanmar doesn't have 'live' PTO, then it will be necessary to have the PTO 'engaged' to raise the 3point arms. However, it shouldn't be necessary to lower the 3point arms.
The reason for this is the pump is on the PTO drive shaft in the transmission.
However, if you have live PTO (pump is driven full-time), running the PTO should not be necessary to raise the 3point arms.

Is that just a quirk of the YM3110? My YM2000B does not have live PTO and there is no connection between the PTO and the 3PH other than sharing fluid. The 3PH is fully operable without the PTO engaged.

I would only think one precaution, and that would have to do with whatever you might have connected to the PTO.

This is a mis-definition of "live pto". A live pto is one which can be engaged and disengaged, and runs independently from the transmission. That is, when you depress the clutch to disengage the transmission, the pto will continue to be powered. The confusion comes when we start talking about the 3 pt hydraulics - which is NOT the pto. As far as I know, all Yanmars have the hydraulic pump driven directly by the engine, not from the transmission.
Older U.S. tractors like the Ford 8N have the hydraulic pump driven by the transmission - so you have to have the transmission turning to use the 3 pt hydraulics. The clutch pedal must be out to turn the hydraulic pump and raise an implement. This is not true for the Yanmar tractors.
On the other hand, most Yanmar tractors do NOT have a live pto. The clutch must be out to power the pto, and it is not independent of the transmission. So when you need to put the tractor in gear to drive, you depress the clutch pedal and the pto stops.
I hope this helps to better define hydraulic and pto functions.

Jose,
What kind of gears are they and how are they related to your FEL? Aren't they operated hydraulicaly or are they somehow mechanical? Maybe you mean valves? Sorry for so many questions but I am following along and trying to understand the problem.

Jose,
I have a really nice YM3110D and hydraulics are live on that tractor. The hydraulic pump is gear driven from the front of the engine not the PTO or transmission. The pickup screen is in the bottom of the rear of the transmission housing facing out on the back of the tractor, just below the PTO shaft. 3 bolts hold the cover on. I always check that, often it is plugged with gunk. From the lower right side (if seated on teh tractor) follow the two metal lines (tubes) up the transmission side towards the front of the tractor. One should be twice as big in diameter as the other. The big one is the suction line, the smaller is the pressure line. I would bet both lead to the front of the engine as mine do.
Feel free to email if I didn't make sense, coffee hasn't kicked in yet.

Hi Mark,
As matter of fact it’s a valve (looks like a gear). The same type (with small difference), use to control the FEL (plse see photos in attach). This valve blocks the hydraulics from the pump which comes from the motor side. So it must be open if you want to work with the 3 point arms.
