How To Tighten Garbage Disposal Blades


Garbage disposal blades can cause serious injury to your hands. Even when the blades are at rest, the sharp edges can cause painful lacerations and cuts that require stitches and medical attention.

Before proceeding, see that the main power is turned off to avoid potential injury.

Look inside the unit for any blockages and debris. You’ll want to ensure it’s clear before tightening the blades.

Please get rid of any lodged food particles and inspect under the blades to ensure nothing gets in the way when you adjust their tightness.

You can check if they’re properly secured by gently wiggling the blades between your fingers. They should be relatively rigid when you tighten the nuts.
