WHY CHOOSE “SEMI-SKIP” OR “SKIP” SEQUENCE CHAIN?
• Consumer users of chainsaws will probably never need to use a semi-skip or skip sequence chain. However, professional 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:

• 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.
