MF5612 - a couple of things

[Swagger]

I have recently bought a 5612 and currently have two issues :
1) Since filling with diesel I am getting a DPF display showing up on the left screen. It has the DPF symbol (drops and waves) and the figure 32% initially, which gradually rises to 37% after a few moments. The display is not shown in the Operator's Manual and I cannot get rid of it using the control panel. No other warnings anywhere. The Urea gauge shows about 30-40% full, so I guess that's what it's showing but all should be OK. It only appeared after filling with diesel for the first time since I bought it. Any thoughts on how to get rid of it so I can see the normal hour meter at startup ?
2) The lower lift arms or PUH will not drop by themselves, but only if there is some weight on them (for example me standing on them). This will be a real pain come hay-making when I will be frequently picking up and dropping off trailers. I am told it is not unusual for them to be very lazy - is that so, and can anything be done about them (everything looks nice and clean) ?

Any ideas on either point would be very welcome.

Def warning is just an extremely cautious warning that pops up on startup when level is below 40%. Like a fuel light only 2 days before you run out
Drop links for pick up hitch is most likely cause of slow arms. Full of dust and dirt. Detach at top and swing down and power washer up the inside.

Lift arms.
Clean everything, take lift rods out grease heavily, wd40 the lift rams, and grease the two grease nipples that are not mentioned in handbook.
They are where the cross shaft is situated, easier to feel and see when you can get arms right down.
Used to be a real problem when doing a lot of 3 point linkage working dry dusty conditions.

Lift rams will be the reason the arms are slow to drop, they are prone to rusting behind the seals making them tight on the cylinder.

And clean the resulting crap off the rams after letting wd40 soak past ram seals.

Thanks all. DPF warning was indeed low ad blue. Drop links for the puh are clear, and with them disconnected the arms still won't drop. Plenty of wd40 applied, rams are clean. Cannot find any grease nipples on the cross shaft! When using the switches by the puh lever the "console locking and operating failure self-diagnostic indicator light" comes on, but doesn't seem to affect anything - arms still drop if I stand on them.

There are grease nipples on the cross shaft,they’re just in a crap place

Have a feeling the tractors come with out the grease nipples in the cross shaft, to stop people over greasing them. Just used to get greased at service by the dealer You have not got the drop rate dial low or in auto?

I know someone who had the exact same problem with link arms on the same tractor from new,he just got told by dealer that’s the way they are because you don’t use them much

By "cross shaft" do you mean the shaft which goes through the gearbox at the front of the lower arms?

No at the top,does it drop on its own when you let the hitch down

Spoke to a dealer fitter about the arms on ours not dropping, he said the seals on the rams too.
Was a little better after a good wash and a coating of oil everywhere though.
