There may be multiple reasons for engine overheating, including foreign objects blocking the exhaust port, oil level below normal, poor heat dissipation around the engine, or damaged carburetor gaskets. What should we do when the engine we are using overheats? What are the reasons for this?

Causes, Inspection, and Basic Troubleshooting of Overheating Faults in Chainsaw Engines:

1. Oil level too low

Solution: Add engine oil (note: do not mix engine oil and gasoline for four stroke engines).

2. The wind guide housing or cooling blades are detached or damaged

Solution: Install new components as needed.

3. Fuel mixing ratio imbalance

Solution: Adjust the carburetor according to the above steps.

4. Muffler air outlet or muffler mesh cover blocked

Solution: Clean the muffler air outlet or muffler mesh cover.

5. Damaged gasket

Solution: Update the gasket with a new one.

What are the factors that affect the prices of chainsaws, chainsaws, and air saws? How to judge the quality or what to pay attention to when making a purchase?

First of all, look at the appearance of the chainsaw. If it is made too rough, it will definitely not work. If it is a chainsaw, the distance between the carbon brush box and the rotor inside should be small, the spark should be small, and the noise of the rotating gears should be as small as possible. The chainsaw rotation has inertia, and the larger the inertia, the better. If it is a chainsaw, it depends on the configuration of the chainsaw, especially the quality of the guide plate and chain. A good imported chain will have a steel seal on each chain tooth. If it is an air saw, you need to give it a try to determine its quality. Actually, no matter what type of saw you buy, it's best to try it with wood. Even if there is no wood, you need to put on a chain and try it out.
