I have a 2004 sportsman 500 and theres a wrench on the instrument panel. What needs done

 

That is a maintenance pre-set interval that is set usually at 50 hours for a oil change service.
If you look in your owners manual it will tell you how to reset and the hours will start counting down again........If you don't have a manual I can post the reset proceedure for you..........Caper...........

 

I ont have a manual
