We have purchased 02 units of UN 03 wheel electric forklifts (FBT16-AZ1). First one was about 10 months back and the other a couple of months back. We are currently faced with a problem of hydraulic system of both the trucks that led us to stop using both of them. Once we start using the trucks, the entire hydraulic system- the hoses, cylinders, hydraulic pump, motor, hydraulic tank are all heating up excessively within about 10 minutes. The heat is felt if one stands near the machine, even the operator can feel this heat from his seat. We have checked hydraulic filter, lines, cylinders, hydraulic pressure and were all normal. We even changed the hydraulic oil of 02 different grades but the problem did not solve. The response we got from UN was not at all acceptable. They don't tell us what's to be done.

Could someone please help us solve this issue ? What is the maximum acceptable temperature of the hydraulic system when a similar forklift is being used ? We can measure the temperature and let you know, if necessary. An urgent assistance / advise is greatly appreciated
