The model is an H80FT, which I believe would be a 4ton with the 4cyl cummins engine. I have been hearing that there has been several engine problems in dusty conditions, which is why hyster came out with the filter upgrade kit which comes with an inner filter. So i would reccomend getting the filter upgrade kits for your cummins models. One of the Hyster dealers I have been speaking with has had atleast 7 trucks come back with engine failure.
Thanks for the reply mate.

what model of truck do you mean mate. up to 3.5 tons in uk are fitted with yanmar diesel engine which have been giving a bit of bother in dusty applications. our 4 ton to 5.5 ton models are fitted with 4 cyl cummins. noisy buggers
