Ryobi Ryobi RY40550 40V HP Brushless 14 in. Chainsaw POOR CUT Error Fix: Slow or Rough Cutting Performance

Error code POOR CUT on the Ryobi Ryobi RY40550 40V HP Brushless 14 in. Chainsaw means: Slow or Rough Cutting Performance. The chainsaw cuts slowly, requires excessive pressure, produces fine sawdust instead of chips, or creates a crooked cut. These symptoms indicate a dull chain, improperly sharpened chain, or incorrect chain tension. A sharp chain should pull itself into the wood with light pressure and produce coarse chips (not fine dust). Sharpen the chain using a round file of the correct diameter for your chain pitch (check the owner's manual — Ryobi 40V saws typically use a 5/32" or 3/16" file). File each cutter tooth at the angle marked on the tooth (usually 30°), maintaining equal length on all teeth. Unequal tooth lengths cause the saw to cut in a curve. Also check and file the depth gauges (rakers) — if they are too high, the chain will not bite into the wood. If you are unfamiliar with chain sharpening, most hardware stores offer chain sharpening for $5-10, or you can purchase a pre-sharpened replacement chain. Also check that the bar is not worn unevenly — a pinched or spread bar rail causes poor cutting.
