CHAIN TENSION (Including units with
chain already installed)
NOTE: When adjusting chain tension,
make sure the bar knob is loosened 1 ½ -- 2
turns. 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
too loose, the chain will sag below the bar.
