- 1). Turn the chainsaw off. Once it completely stops, grab the plastic chain brake on the top of the saw and push it backward.
- 2). 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.
- 3). Locate the knob on the bottom half of the saw where the motor and the chain meet.
- 4). Loosen the chain by rotating the knob counterclockwise. Tighten the chain by moving the knob clockwise.
