That model should have a GE SX controller.
when you turn the key off, the display will give the traction hours followed by the lift hours (assuming it has transistor lift) on the dash display.

There is a slight possibility that the unit has EV100 controls, the hours will display the same way, just the display is different. (LED vs. LCD on the SX's)

I'm afraid that there is no way to be absolutley sure of total truck hours, since the hour meters reset when you change controllers and it's up to the tech to set the hours that are displayed. (so obviously any iffy dealer could set whatever hours they felt like)

*note if the unit has contactor hydraulics, then only traction hours are displayed

They are a great series of trucks, just watch out for the batteries.

You can expect to replace the battery @ about 5yrs of age.
The age of the battery is a little more difficult to figure out.
I believe only GNB puts a proper date on a label.
The rest have stamps on the first inter-cell connector from the positive post.
Some are stamped with dates, but most have codes that have to be deciphered by the respective battery supplier.


Hope this helps...
