Let's face it: everyone loves chainsaws. A chainsaw can make very short work of any trees, bushes, or branches that happen to be causing a problem. I have even seen a small chainsaw skillfully used in place of a large circular saw for home remodeling - no electricity required! They are seriously handy devices. The one problem with chainsaws is that they require maintenance. In fact, they require a lot of maintenance in order to perform optimally. You can save some bucks - and have a lot of fun - by servicing your chainsaw yourself.
