Chain Maintenance - Echo CCS-58V Operator's Manual

MAINTENANCE
 Turn the chain tensioning screw clockwise to
increase tension the chain.
NOTE: A cold chain is correctly tensioned when
there is no slack on the underside of the guide
bar, the chain is snug, and it can be turned by
hand without binding.
 Retension the chain whenever the flats on the
drive links hang out of the bar groove.
NOTE: During normal saw operation, the tem-
perature of the chain increases. The drive links
of a correctly tensioned warm chain will hang
approximately 0.050 in. out of the bar groove.
The tip of the supplied combination wrench can
be used as a guide to help determine the correct
warm chain tension.
NOTE: New chains tend to stretch; check the
chain tension frequently and tension as re-
quired.
CAUTION
A chain tensioned while warm may be too tight
upon cooling. Check the "cold tension" before
next use to avoid possible injury.

Chain Maintenance

See Figures 37 - 39.
WARNING
Remove the battery pack and make sure the
chain has stopped before you do any work on
the saw.
Use only low-kickback chain on this saw. This
fast-cutting chain will provide kickback reduction
when properly maintained.
For smooth and fast cutting, chain needs to be
maintained properly. The chain requires sharpen-
ing when the wood chips are small and powdery,
the chain must be forced through the wood dur-
ing cutting, or the chain cuts to one side. During
maintenance of your chain, consider the following:
 Improper filing angle of the side plate can in-
crease the risk of a severe kickback.
 Raker (depth gauge) clearance.
 Too low increases the potential for kickback.
 Not low enough decreases cutting ability.
