What does the chain saw chain 3/8"P mean?

Chain pitch represents the width of each drive tooth of the chain, and 3/8 of an inch is 9.525 mm in metric.
The commonly used specifications of chain saw chains are large 3/8, small 3/8, 325, 404 and other specifications. These numbers are the pitch of the chain/2. The larger the pitch, the larger the chain. This is from the chain pitch. Points, chains with the same pitch are still different, then it depends 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 and numbers on the chain packaging box are in imperial units.
There are also right-angled and rounded teeth. In fact, the only difference between a right-angled and a rounded corner is that a right-angled chain looks sharper, but in fact wears faster, a rounded chain does not look sharp enough. Wear-resistant.

For prolonged storage of the saw, empty the fuel tank and clean it in a well-ventilated area. Always run the engine before the carburetor is dry to prevent the carburetor diaphragms from sticking together. Remove chainsaw chain and guide bar, clean and spray with anti-rust oil. Thoroughly clean the implement, especially the cylinder cooling fins and air filter. If using bio-chain lube, fill up the lube tank.
Even if the chain saw is used and maintained according to the regulations, some parts of the power tool will have normal wear and tear, so 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 of the vibration damping system.
