Just like any other piece of equipment that uses a blade, there comes a time when replacement of the blade is necessary.

Wear leather work gloves when replacing blades to avoid accidental cuts.

  2. Turn the blade guard lever clockwise toward the direction of the guard until it stops. The lever is near the front of the blade guard. Lift the blade guard up to open it and access the blade.
