Charge pressure

[Web1717]

I have a bobcat S175 and when I start it up everything seems to be ok but a couple seconds later the alarm is going off and flashing the charge pressure light and then shutting machine down. Changed filter and still the same issue. Any ideas would be helpful.

Charge pressure is provided by the gear pump and maintained by the charge relief in the hydrostatic pump case. Is lift and tilt working good? if you take either lift or tilt maxed out in either direction over main relief will the engine lower in RPM's slightly? Check main drive belt and tensioner as well.
