The commonly used specifications of chain saw chains are large 3/8, small 3/8, 325, 404 and other specifications. These numbers are the chain pitch/2. The larger the pitch, the larger the chain, which comes from the chain pitch. For chains with the same pitch, there are differences, depending on the thickness of the guide teeth. The thickness of the guide teeth is 1.6mm, 1.5mm, 1.3mm and other common specifications. The specifications on the chain box are all in English units.
There are also right-angled and rounded teeth. In fact, the only difference between a right-angled and a rounded angle is that the right-angled chain seems to be sharper, but it wears faster. The rounded-angled chain does not seem to be sharp enough. Wearable.

For long-term storage of the chain saw, the fuel tank should be emptied and cleaned in a well-ventilated place. Always run the engine before the carburetor dries to prevent the carburetor diaphragms from sticking together. Remove the chain and guide plate of the chain saw, clean it, and spray it with anti-rust oil. Thoroughly clean the implements, especially the cylinder cooling fins and air filters. If using bio-chain lubricants, fill the lubricant tank.
Even if the chain saw is used and maintained in accordance with the regulations, some parts of the power machine will have normal wear and tear. Therefore, it must be replaced in time according to the model and usage of the parts. These parts include saw chains, guide plates, transmission parts, filters, starting devices, spark plugs and parts for vibration damping systems.
