CHAIN TENSION (Including units
with chain already installed)
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 knob is finger tight only.
Attempting to tension the chain when the bar
knob is tight can cause damage.
Checking the tension:
Use a screwdriver 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.

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.
