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.
