How to Adjust the Chain Tension on an Electric Chainsaw

Electric chainsaws are cheap and economical for consumers who only need a chainsaw to chop firewood or cut down small branches.
Electric chainsaws have a toolless adjuster under the chain.Electric chainsaws have a toolless adjuster under the chain.
These chainsaws are designed for the light user in every way possible. For instance, the toolless chain tensioner, a knob located on the bottom of the machine, tightens and loosens the chain with just a spin of your finger.

Step 1

Turn the chainsaw off. Once it completely stops, grab the plastic chain brake on the top of the saw and push it backward.

Step 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.

Step 3

Locate the knob on the bottom half of the saw where the motor and the chain meet.

Step 4

Loosen the chain by rotating the knob counterclockwise. Tighten the chain by moving the knob clockwise.
