Chain Cutter Sequence Terminology
Standard
Semi-skip
Skip
Why Choose “Semi-Skip” or “Skip” Sequence Chain?
• The type of wood being cut and other factors will affect the choice of the chain type and chain sequence, but with the full‑size 3/8" pitch and .404" pitch chains, preferred by professional and commercial operators who use longer bars, the following general guidelines will be useful
Consumer users of chainsaws will probably never need to use a semi-skip or skip sequence chain. However, profes- sional or commercial chainsaw operators who use their saws frequently and who use longer bars may prefer a semi-skip or skip chain for these reasons: • Fewer cutters to sharpen makes sharpening faster and r • Greater clearance for better chip flow – the larger the wood being cut and the longer the bar used, the more important good chip flow becomes
