4.4- Chain tension adjustment and Control
Control the chain tension regularly because new chains lengthen during use.
When in COLD STATE: the saw chain must adhere to lower side of the guide bar, but it must be able
to be pulled by gloved hand.
When reached OPERATING TEMPERATURE: the saw chain lengthens and it slacks.
Parts of the saw chain must not rise from the notch on the lower side of the guide bar – saw chain
