Dear Swoop 223
Thank you for the response. UN does not take the issue seriously in spite of my repeated requests and telephone calls. I even agreed to bear all costs of an engineer's visit to Sri Lanka. They are refusing to send an Engineer. Both machines are under warranty. It is a shame on UN !
It is NOT the battery that causes the heat generation and is actually the hydraulic system that generates the heat. Based on the specs of the first truck we ordered the 2nd truck and when it arrived we noticed that the mast and tilt jacks of the 2nd truck are fairly bigger compared to the 1st truck. When this was informed to UN the answer was that they had improved the masts. But I personally feel the mast of 2nd truck is oversized and it probably could be mast fitted to a truck of higher capacity and it may create a strain on the hydraulics. My question is why the first truck too developed the same problem ? No attachments are fitted except the side shifter. Hose sizes, number junctions can check and let you know. UN is also sold in U S. Do you know the distributor in U S and can we get some advise from them if they have faced with a similar situation ?
