Using a Chainsaw on Wet Wood - To keep your chainsaw from binding on wet wood, wipe the whole bar with bar or chain oil - repeat as needed. (Be sure it isn't running when you do it, dumbass!)
Homemade Chainsaw Oil-Applicator - A plastic mustard squeeze bottle makes a good chainsaw oil applicator because it's easy to carry along, eliminates the need for a funnel, and prevents drips and spills.
Chainsaw Oil - There is a special oil which is sold for lubricating motorcycle chains. It sprays on as a liquid, dries as a film, and contains molybdenum disulfide as well as other lubricants. This spray works especially well on chainsaws that do not have an automatic oiler.
Chainsaw Spare Parts Kit - Make a spare parts kit to pack with your saw when going into the woods. An extra chain loop, a spare bar, a clutch assembly and a spark plug will help you through most saw failures. These are parts you are going to need eventually anyways, so buy them two at a time and keep a spare with you.
When to Sharpen the Chain - Dull saws don't cut well and waste your time. You need to sharpen the chain when it is producing a fine sawdust rather than chips.
Tightening the Chain - Once you install a new chain on your saw it will stretch out within a half dozen cuts or so and will need to be tightened again. You must do this not only to minimize wear but more importantly, to make sure the chain doesn't fly off the bar.
