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

you use your saw. Always check chain tension each
time before you start the chain saw.
