All chain saws can cause kickback during operation, leading to loss of control of the machine and, as a result, to dangerous accidents.Kickback is the sudden rejection of the saw in the direction of the operator with simultaneous upward pull of the bar.It occurs when the upper quarter of the perimeter of the bar's tip comes into contact with a hard object, such as: a branch or log, as well as when the bar is jammed in a cut.The 91P chain thanks to the shape of the links and the use of a special anti-kickback link offers excellent protection against kickback.Choose the right chain for your chainsawCheck if your old chain has the right numbers stamped on it, symbolizing the type of chain.You can notice them on the lower part of the cutting chain - on the so-called guide link, i.e., the one that enters the bar groove.If the minted number is "91", then its parameters mean: pitch 3/8 inch and thickness of the guide link 1.3 mm.Now just count the guide links in the whole chain and choose it in our store.Please note that you may also encounter the designation of other manufacturers. In this case, a comparison table will be useful. Number of links: 52 pcsThe guide link of the cutting chain is the link that enters and moves in the groove of the bar.Although the cutting chain may correspond to the model of your saw, its length depends on the length of the bar you put on.In order to select the right length chain: CONSISTENTLY count the number of guide linksor look for special markings on the bar - the number of links is usually marked with a number next to the letters "DL" (from Drive Links)Pitch: 3/8" (low profile)Chain pitch is the distance between the axes of the first and third rivet (anywhere on the chain) divided by two. The pitch in the entire cutting system (chain, bar, clutch drum) must be the same. For this product - the pitch is 3/8 inch (Distance between three rivets is about 19 mm).Important! For used cutting chains, this distance may increase due to chain wear and tensile properties.3/8 inch (low profile) is a common pitch used on small, lightweight chainsaws, either petrol or electric.Chisel Type: "Chisel Chisel" type cutting link chain:Chisel Chisel type cutting link chains, have chisel-shaped teeth with a sharp profile with two cutting corners.
