Adjusting the Chain Tension
WARNING
use . Upon initial operation, new chains can lengthen considerably . This is normal
during the break-in period and the interval between future adjustments will lengthen
quickly.
WARNING
This may injure the operator and damage the chain! A loose chain will cause rapid wear
to the chain, guide bar and sprocket!
Tensioning the chain too tightly will overload the motor and cause damage, and
insufficient tension can cause chain derailing, whereas a correctly tightened chain
provides the best cutting characteristics and prolonged working life! The chain life
mainly depends upon sufficient lubrication and correct tensioning!
1. Stop the motor and remove the battery pack before adjusting the chain tension.
2. Loosen the side-cover knob.
3. Turn the chain-tensioning adjusting knob to
adjust the chain tension. See the section:
"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.
During normal saw operation, the tempera-
•
ture of the chain will increase. The drive links
of a correctly tensioned warm chain will hang
approximately 0.050 in. (1.3 mm) out of the
bar groove (Fig. 29).
New chains tend to stretch; check chain tension frequently and tension as
NOTICE
required.
A chain tensioned while it is warm may be too tight upon cooling. Check the
NOTICE
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.

Always check the
saw-chain tension before use, after the first cuts, and regularly during
Always maintain proper chain tension! A loose chain increases the
risk of kickback! A loose chain may jump out of the guide bar groove!
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 .
