Stihl MS 251 Problems and Solutions

The Stihl MS 251 is a popular chainsaw that is known for its reliability and ease of use. However, even the best chainsaws can experience problems from time to time. Here are some of the most common problems that can occur with the Stihl MS 251, along with step-by-step solutions:

• Chainsaw won't start: This is the most common problem with chainsaws, and it can be caused by a number of things, including a bad spark plug, a clogged carburetor, or a lack of fuel. To troubleshoot this problem, first check the spark plug to make sure that it is clean and properly gapped. If the spark plug is okay, then check the fuel level in the tank. If the fuel level is low, fill up the tank and try starting the chainsaw again. If the chainsaw still won't start, then you may need to clean the carburetor.
• Chain saw cuts poorly: If your chainsaw is cutting poorly, it could be due to a dull chain, a misaligned chain, or a dirty bar and chain. To check the chain, remove the chain guard and visually inspect the chain teeth. If the teeth are dull, you will need to sharpen them. To align the chain, loosen the chain tensioner and adjust the chain until it is aligned properly. To clean the bar and chain, use a wire brush to remove any dirt or debris.
• Chainsaw overheats: If your chainsaw is overheating, it could be due to a number of things, including a clogged air filter, a dirty muffler, or a faulty spark plug. To troubleshoot this problem, first check the air filter to make sure that it is clean. If the air filter is dirty, replace it. If the air filter is clean, then check the muffler to make sure that it is not clogged. If the muffler is clogged, clean it out. If the muffler is not clogged, then you may need to replace the spark plug.

These are just a few of the most common problems that can occur with the Stihl MS 251. If you experience any of these problems, you can try troubleshooting them yourself using the steps above. If you are unable to fix the problem, you should take the chainsaw to a qualified service technician.
