Snow Joe SWJ800E-RM Saw Joe 8-Inch 6.5-Amp Electric Pole Chain Saw - Manual (Page 9)

Chain Tension
Check the chain tension before using the saw when the chain
is cold. The 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 turn it by hand without binding.
During normal saw operation, the temperature of the chain
will increase. The drive links of a correctly tensioned warm
chain will hang approximately 0.050-inch (1.25mm) out of the
bar groove (Fig. 12). Be aware that a chain tensioned while
warm, may be too tight upon cooling. Check the “cold tension”
before next use. The chain must be re-tensioned whenever the
flats on the drive links hang out of the bar groove (Fig. 12).
NOTE: A new chain tends to stretch so check the chain
tension frequently and retension as required.
Chain Sharpening
For smooth and fast cutting, you need to maintain the chain
properly. The chain requires sharpening when the wood chips
are small and powdery, if you must force the chain through the
wood during cutting, or the chain cuts to one side.
Guide Bar Maintenance
When the guide bar shows signs of wear, turn it over on the
saw to distribute the wear for maximum bar life. Feathering or
burring of the bar rails is a normal process of bar wear. You
should smooth such faults with a file as soon as they occur.
Replace a bar with any of the following faults:
• Wear inside the bar rails permitting the chain to layover
sideways
• Bent guide bar
• Cracked or broken rails
• Spread rails
Turn the saw over, check the underside of the guide bar, and
make sure that the lubrication holes and chain groove are free
from impurities.
