My blade is loose

If the motor is running, but the BLADE is not spinning, then the BLADE may not be properly installed. Unplug the unit from the extension cord. Please ensure the washer, BLADE, washer, and hex head nut – in that order from the motor outward – is tightly secured.

Use the bigger wrench to hold the washer and blade while using the smaller wrench to loosen the bolt counter-clockwise.
