Chainsaw Trouble Checklist and Other Tips From Wilmington Local Tree Service
If you perform any kind of tree maintenance or other heavy cutting tasks in your garden then you know that chainsaws are a key tool for getting these kinds of jobs done.
That being said, they can be temperamental pieces of equipment. A regime of regular maintenance and cleaning will go a long way to eliminating many of the potential mechanical problems you may encounter.
With the best will in the world however, sometimes things will just go wrong! Here is a checklist of common issues that can affect your chainsaw from time to time. If after all you can’t seem to make it work, call our tree service and we’ll be on our way to help you out.
Guide Bar Groove
The channel on the chainsaw’s bar that guides the chain can often become clogged with dirt, bits of shredded tree and other lumps of debris. When this happens the chain will not be able to rotate freely. It’s therefore extremely important that you remove the chains and clean this groove frequently. After removing the drive case cover and the chain itself, use a small flat head screwdriver to clean out the groove. File down any imperfections or nicks in the bar groove too.
Whilst you have the drive case open, it’s also a good idea to take a look at the two oil inlet ports located on the bar. These can also become clogged with dirt and debris and affect the performance of your chainsaw. Clean them out with the same small flat head screwdriver or a piece of bent wire.
The power sprocket, also known as a drive sprocket, is located on the centrifugal clutch and helps transfer power from the chainsaw engine to the chain itself. As such, over time it will eventually wear out – although in a modern machine, power sprockets are designed to last longer than ever bef ore. With the drive case open, simply check the sprocket for signs of advanced wear and replace it when necessary.
Chainsaw engines are designed to be air-cooled. This means they therefore rely on a flow of air to remove excess heat and keep the engine operating safely. Chainsaws are designed with integrated cooling fins to help distribute an even flow of cooling air. Like the other parts of the machine, these fins can become blocked with dirt and grime, making them less effective over time. To get to them, remove first the starting house, then the drive case cover, the carburetor cover and finally the cylinder housing itself. Once exposed use a degreasing solvent and a brush to thoroughly clean those fins.
Spark plugs and Ignition
Key parts of the chainsaw design, and often the cause of mechanical breakdown. Even if they aren’t broken, spark plugs can easily work lose and if they are not in place correctly, you won’t get your machine to fire. Remove them with a socket wrench and carefully clean first with a wire brush and then with a dry rag or cloth. Remember that when you put them back, they don’t need to be tightened in as much as possible – just use a moderate amount of force. When the plug is replaced completely, always replace it with the same type.
