    OPERATION OPERATOR’S MANUAL PRE-CUT CHECKLIST CAUTION CAUTION To maximize the life of the cutting system, ensure that proper chain tension is maintained. If tension is too tight, it will lead to excessive chain stretch, and a lot of the saw’s power will be used to overcome friction. In severe cases the chain may not turn at all and can lead to chain breakage.
