Turn the chainsaw off. Once it completely stops, grab the plastic chain brake on the top of the saw and push it backward.
Pull on the chain lightly. If it has no give, it is too tight. If the chain is barely hanging on the bar, then it is too loose.
Locate the knob on the bottom half of the saw where the motor and the chain meet.
Loosen the chain by rotating the knob counterclockwise. Tighten the chain by moving the knob clockwise.
Things You Will Need
