The Working Process Of The Tension Screw of A Chainsaw
Sometimes we need to tighten or loosen the chain. Suppose in summer the length of the metals increases a little bit. That’s the reason you face the chain becoming loose with its guide bar.
In winter due to the temperature down, the length of the chain becomes shrinks, due to this, you feel that the chain becomes closely tight with its guide bar.
Also when we use the chainsaw due to the fast-moving parts of the chainsaw they become hot and this type of temperature misbalance makes the chain lose or tight accordingly.
