Kubota KX040-4 Exhaust temp rise warning message

[cr2410]

I've been getting a warning message "Exhaust temp rise Operate Carefully Possible to work" on my kx040-4 with aprox (1900hrs).

It's appearing after not very heavy workloads on the machine. It's accompanied by a very handy warning bell, which rings every 60 seconds or so. I had this appear after working outdoors when the temp was below zero (Celsius), so it do not believe it's related to the working environment temperatures.

I can't help but think it has something todo with the DPF exhaust system. The system did it's burn off within the last couple hours of work which didn't seem to make this go away. I have a bad feeling I need to clean my DFF filter or worse replace it.

Has anybody else encountered this warning? Any suggestions on how to remediate it?

I am having the same issue with my KX-040-4. its a 2015. If you figured anything out or if anyone else knows anything please let me know because I'm afraid its gonna breakdown on site one day.

Try the simple things first. Check the radiator for debris and dirt, not so much for coolant temp but airflow. Check the air filter, as a clogged air filter will cause exhaust temps to rise.

So... were you ever able to identify and/or fix this problem??

Four years ago…and the OP hasn’t logged in in five years. Might try emailing him.

I joined this forum and evidently I’m not navigating properly. I posted my problem and all I see is other post just the same as mine but no answers or remedy to fix the damn problem

The warning and chime come on when the DPF is being cleaned. The process seems to take 15 minutes or so. Occurs maybe every 10 hours or so on my KX040.

Run the motor full throttle while cleaning the DPF. In normal use, also run full throttle, or at least 1900-2000 rpm. DPF's do not like low rpms.

They have passive regen like all those poses so higher rpm’s mean less problems in theory of course
That’s what it is based on
