correct tension of a cold chain is when there is no slack on the underside of the
guide bar; the chain is snug, but you can rotate it by hand without binding.

tensioned while warm, may be too tight upon cooling. Check the " cold tension"
before next use. The chain must be retensioned whenever the flats on the
drive links hang out of the bar groove (Fig. 16).

An authorized service center will sharpen the chain using the right tools to
