Once the band saw blade is loose and the front guard has been lifted, the next step in changing a band saw blade is to remove the rear blade guard. This blade guard covers the blade as it travels upwards from the bottom tire to the top tire, and protects the operator in the event of a blade breakage.
To remove this blade guard, simply remove the screws that hold the blade guard in place. Typically, a Phillips screw on the top and bottom of the guard secure the guard to the chassis. Set the guard and screws aside for the time being.
