CHAIN TENSION
WARNING:
To avoid possible serious injury, never touch or adjust the chain while the motor is running.
The saw chain is very sharp; always wear protective gloves when performing maintenance to
the chain.
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 knob clockwise to tension the chain. See the section: "REPLACING THE
BAR AND CHAIN" in this manual for additional information.
NOTE:
A cold chain is correctly tensioned when there is no slack on
the underside of the guide bar, the chain is snug, but it can be turned by
hand without binding.
4. Chain must be re-tensioned whenever the flats on the drive links hang
out of the bar groove (see fig.4).
5. During normal operation, the temperature of the chain will increase.
The drive links of a correctly tensioned warm chain will hang
approximately 0.050 in. out of the bar groove (see fig.5).
6. Retighten the side cover knob.
NOTE:
New chain tends to stretch; check chain tension frequently and
tension as required.
NOTICE:
Chain tensioned while warm, can be too tight upon cooling. Check the “ cold
tension”
before next use.
