Chain Maintenance - Echo CCS-58V Manual Del Operador

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.
NOTICE
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 35 - 37.
WARNING
Remove the battery pack and make sure the
chain has stopped before you do any work on
the saw to avoid accidental starting and pos-
sible serious personal injury.
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.

If cutter teeth have hit hard objects such as nails
and stones, or have been abraded by mud or
sand on the wood, have service dealer sharpen
chain.
NOTE: Inspect the drive sprocket for wear or dam-
age when replacing the chain. If signs of wear or
damage are present in the areas indicated, have
the drive sprocket replaced by a service center.
How to Sharpen the Cutters
See Figures 38 - 39.
Be careful to file all cutters to the specified angles
and to the same length, as fast cutting can be
obtained only when all cutters are uniform.
The saw chain is very sharp, always wear pro-
tective gloves when performing maintenance
to the chain to prevent serious personal injury.
