Shut the machine off and open the idler and drive doors.

Loosen the carbide locking levers by turning counter clockwise 1/4 turn.

At the top of the head, the saw blade runs in a protective channel. Grip the blade at each end of this channel and twist the blade teeth down past the channel and slide the blade forward. Let the blade rest on the out feed table, then slide the blade down and out of the carbide guides.

Before installing the new blade, check that it measures 1.615' wide including the teeth.

Your new blade will be in a coil. While wearing gloves, hold the blade away from yourself, twist the blade to uncoil it. Do not let the blade teeth bounce on the concrete floor as some damage to the blade may be caused.

Warning: Ensure the machine is turned off and unplugged before starting the procedure.
