How to Fix Chainsaws

Chainsaws are incredibly useful, but they can be a bit difficult when they fall into disrepair through lack of use or overuse without proper maintenance. Fortunately, although a chainsaw looks and sounds intimidating, there is not actually all that much to one. There are two basic parts of a chainsaw, the motor and the bar that carries the chain. Your fix will depend on which part of the chainsaw is not functioning.

Things You'll Need

• Screwdriver
• Spark plug wrench (should have come with the chainsaw)
• Can of starting fluid
• Heavy leather gloves

Instructions

1. Remove the spark plugs. Using the spark plug wrench, which should fit them exactly, gently pull them out of their sockets. Spark plugs are almost always the culprit when it comes to a chainsaw that will not start.

2. Refresh the spark plugs. Spray a blast of starting fluid inside the spark plug hole, and then put the plug back in. Tighten it down.

3. Pull the starter cord. If the chainsaw starts and runs, you should be good to go. If it doesn't fire at all, the spark plug is bad and needs to be replaced. You can do this by simply purchasing a matching spark plug model and plugging it into the socket using the wrench.

4. Unclog the chain gearing area. With your spark plug wrench, there will be one or two nuts on the side of the chainsaw, which when taken off, will allow access to the actual chain gears. Remove those nuts and then take off the panel cover. The gearing that the chain is propelled by can often become clogged with sticks, wood chips and twigs. This whole area needs to be cleaned out completely.

5. Test the chain's ability to run. Replace the panel and grab the chain with your gloves on. Attempt to pull it on the bar. If it pulls along smoothly, you are finished. If not, then you will need to investigate other options.

6. Check the track on the chainsaw bar. The bar has a track along the edges that may have become pinched. Take your screwdriver, place it in the track and slowly go around the entire outside edge. If your screwdriver stops at a point, the track needs to be gently pried open until you can easily move the screwdriver along again. Do this along the entire length of the bar. When you have finished this, you should be able to start your chainsaw. If not, then it is probably time for a new one.

Tips & Warnings

• Always be very careful when working with any type of power tools. If you are not comfortable or familiar with them, work under the supervision of someone who is.
