D4K LGP not driving

[trevoratt]

The screen has a pic of a blade, BLADE is written and on the top you can toggle ON or OFF using the buttons under the display,
for the park brake PBLO is displayed with ON or OFF on the top.

On other machines like the D6T there are options like blade raise ON/OFF but I don't see anything like that on the D4K.
On the D4K We have the wiring for Accugrade on this machine but it is not installed.I don't know if its related.

Late post, well after not working on the d4k for a while I decided to have a go at it again and it works!!!
It drives and all functions work, I did nothing. I assumed it might have been air trapped in the hydraulics somewhere but it drove when I manually powered the pump solenoid sooooo I still don't know what the problem was. Maybe air in the pilot system, who knows. Maybe the electrical reset for itself???
I hope I don't get this again.

Thanks for all who gave advice, information and had the patience to try to help. Cheers!

What problem exactly.? If you read through the thread so far it touches on at least half a dozen different things.

Also do you have an Operation Manual.?

Good morning Sir Nige, the problem was parking brake lamp blinking when releasing the parking brake switch. The machine not driving, but the blade functions work normal.

Anyhow, I manage to find the problem, the parking brake lock out is activated, so I just change the parameter to deactivate. I just don't know why it has been activated.

I appreciate your response.

I don't have any manual for this machine sir, maybe you can help me with this.

Thanks,

I don't have any manual for this machine sir, maybe you can help me with this.

I can help you in as much as direct you to a place where you can download a genuine Cat manual for $52. You can also buy the manual in a paper or CD format but they will have additional shipping costs on top of the price shown.

Put SEBU8213 in the box and click Search. The illustration below should appear. Paid with a credit card the download will be available in 5 minutes or less. FYI the O&M Manual also contains all the necessary information for carrying out basic machine maintenance as well as operation. It is NOT a service/repair manual.
