CAUTION:
• Always clean out all chips or foreign matter adhering to
the blade, blade clamp and/or slider. Failure to do so
may cause insufficient tightening of the blade, resulting
in a serious injury.
To install the blade, loosen the bolt on the blade clamp with
the hex wrench. Keep the back edge of the blade against the
roller and insert the blade between the blade clamp and the
slider as far as it will go. Make sure that you are inserting the
blade into the proper position.
Fit the pin on the slider into the hole in the blade shank.

extracted even though you try to pull it out.
