Chain tension

(Including units with chain already installed)
a WARNING: Wear protective gloves when
handling chain. The chain is sharp and can
cut you even when it is not moving.
Note: When adjusting chain tension, make sure the
bar nuts are finger tight only. Attempting to tension
the chain when the bar nuts are tight can cause
damage.
Checking the tension
Use the screwdriver end of the chain adjustment tool
(bar tool) to move chain around guide bar. If the chain
does not rotate, it is too tight. If the chain is too loose,
it will sag below the bar.
Adjusting the tension
Chain tension is very important. Chains stretch during
use. This is especially true during the first few times
you use your saw. Always check chain tension each
time before you start the chain saw.

of guide bar, then turn adjustment screw 1/4 turn
clockwise. Repeat until sag does not exist.
5. While lifting tip of guide bar, tighten bar nuts
securely with the bar tool.
