Daewoo DH130 does not shut down

My cousin recently acquired a Daewoo/Doosan DH130 SN# 0263 89 04
The unit will not shut down when turning off the key. The book that came with it has some electrical diagrams which seem to not match whats in the unit. for example it shows an electric fuel pump, and electric fan but neither are on the unit.

Can anyone offer any insight on this?

Hi,

Is there any sings of repeatedly clicking solenoides or relays ?(i assume that this machine has a controller)

If there is a engine shutdown solenoid ( fuel shut off solenoid ) check whether voltage is available at the solenoide immediately after key swith turned off.

Or

If your engine shuts off by pulling the throttle below idle speed, then the issue could be a throttle cable adjustment problem.

After key seitch is turned off does the engine take too much time to shutdown or doesn't it shutdown at all.does the rpm change after key sw turned off ?

Good day see if this looks the same

Anuradha, Defiantly no electronic shutdown solenoid on the injection pump nor an electric fuel pump or any solenoid on the fuel control lever. It appears to be all mechanical. It appears there is some adjustment left on the fuel control lever on the injector pump. I was planning on starting there to attempt to cure the problem but wanted to pick brains before I made any changes first in hopes someone has been on one of these dinosaurs before or had access to Doosans heavy machinery side.


Uffex, it looks similar but much older its a 1989 I believe.

Good day W Hunter
If you can post what information you have we can try to help out, I have checked the archives do not go back ant further.
