BLADE REPLACEMENT

See Figures 20– 22.

After extended use, the blade on your biscuit joiner may
become dull. If you accidentally hit a nail or other blunt
object, it will dull or break the blade. These situations
require replacing the blade.

HOW TO REPLACE THE BLADE

Unplug your detail biscuit joiner.

WARNING:

Failure to unplug your detail biscuit joiner could result in
accidental starting causing possible serious personal injury.

■

Place your biscuit joiner upside down on a workbench and
remove the bottom shoe screws (4) and bottom shoe.
