After you take your machine out of storage and before you start the engine, you will want to inspect all the filters, wires and fluids. Often times critters can find their way into your machine over the colder months and build nests, chew wires and puncture holes in tubes. Make sure you've removed your filters, cleaned off any debris and these components are still in good functionable condition. Check all of your fluid levels and inspect your machine for leaks.
