Installing The New Blade
Position the new blade so the teeth face the right way. The blade must sit flat against the grinder’s flange.
Use the blade nut to hold the blade tightly in place. Turn the nut clockwise until it is secure but avoid overtightening.
Check the blade alignment by spinning the grinder slowly. The blade should not wobble or touch the guard. If it does, loosen the nut and adjust the blade position.
Testing The Grinder
Reconnect the power cord to the grinder securely. Make sure the switch is off before plugging in. This prevents accidents.
Perform a test run by turning on the grinder briefly. Watch the blade spin smoothly without wobbling.
Listen carefully for any unusual noises. Grinding, rattling, or squeaking sounds may indicate a problem.
If noises persist, stop the grinder immediately. Check the blade and mounting before using again.
