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.
