CHAIN TENSION (Including units
with chain already installed)

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

too loose, the chain will sag below the bar.
