I have a Daewoo 450 Excavator, the underlined red warning light have been on and the machine imediately gets overheated , do they relate to each other ? pls help http://tinypic.com/r/2i4z0m/8
Pretty sure it mean Stop!
The light you have on is the air filter clogging warning light, the filter is/may be clogged. This could cause a heating issue with a low air flow, is the machine showing black smoke bad also. I would pull the air filter, inspect and change out, tighten the fan belts, check the rad, oil cooler, ac condenser for blockage and air flow. If you machine has a thermo housing made of plastic hooked into the rad hoses I would also change it out if the problem keeps up our 220lc 111 has had a dozen in the past.
The top right is low engine oil pressure warning light also.
