Mikhalych, 65, Kostroma

“Bought for the house, carefully studied the ratings on the network and after consulting with sellers. I can do all the things I have to do with it. The chainsaw is indispensable in the household: powerful, lightweight, economical. The carburetor is excellent: the saw runs quietly, doesn’t stutter, accelerates well. I don’t see the point in buying an expensive branded tool, if there is a champion 251-18.


“Bought it a month ago. Sawed with it for three days, does everything fine. Then I couldn’t start it up. As it turned out, flew the magnet – had to buy a new one. After replacing it, the chainsaw started on the first try. I think it was a factory wedding.

The engine is running

Filling up the engine is a necessary setup step for the chainsaw and takes 5 to 10 operating cycles. A work cycle is the time from refueling to the next chainsaw.

The engine uses a 1:25 fuel mix (oil: gasoline) for the work cycles. After filling the gasoline tank, you must prepare a 1:50 mixture.
