Chain Maintenance - Skil PWRCORE 20 CS4562B-00 Manual Del Propietário

"Replacing the Bar and Chain" in this manual
for additional information.
A cold chain is correctly tensioned when
•
there is no slack on the underside of the
guide bar and the chain is snug, but it can be
turned by hand without binding. The chain
must be re-tensioned whenever the flats on
the drive links do not sit in the bar groove.

temperature of the chain will increase. The
drive links of a correctly tensioned warm
chain will hang approximately 3/64 in.
(1.3 mm) out of the bar groove (Fig. 28).
NOTICE: New chains tend to stretch; check
chain tension frequently and tension as
required.
NOTICE: A chain tensioned while it is warm may be too tight upon cooling. Check the cold
tension before next use.

Chain Maintenance

WARNING
WARNING
Use only low-kickback chains on this saw. This fast cutting chain will provide kickback
reduction when properly maintained.
A properly sharpened saw chain cuts through wood effortlessly, even with very little pressure.
Never use a dull or damaged saw chain. A dull saw chain cutter leads to increased physical
strain, increased vibration load, unsatisfactory cutting results and increased wear.
For smooth and fast cutting, the chain needs to be maintained properly. The chain requires
sharpening when the wood chips are small and powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one side. During maintenance of your chain, consider
the following:
Improper filing angle of the side plate can increase 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 the chain sharpened by a qualified service technician.
NOTICE: Inspect the drive sprocket for wear or damage when replacing the chain. If signs
of wear or damage are present in the areas indicated, have the drive sprocket replaced by
qualified service technician.
Remove the battery pack before performing any maintenance; failure
to heed this warning could result in serious personal injury.
Always wear gloves when handling the saw chain; these components
are sharp and may contain burrs.
