Petrol chainsaws

Chain saw

— chain saws with petrol engines.

The working element in such saws is a looped chain moving along an oval guide rail. Chain saws in general are quite versatile, they are used both for wood and other materials, including even figured carving of sculptures from concrete or ice. As for gasoline engines, their main advantages are battery life and high power: such motors do not depend on sockets and battery charge, and the power of gasoline saws is much higher than that of cordless electric saws. On the other hand, such motors are more expensive and more complicated (both by themselves and in operation), they are rather heavy and bulky, and due to the exhaust gases generated during operation, you can only use gas tools outdoors (in extreme cases, indoors). with very good ventilation).
