Installing or Changing the Blades

Introduction There are two types of blades available for the trowel:
Combination blades can be used throughout the entire concrete working

process, from floating to finishing stages. They are designed for rotation in one
direction only.
Finish blades are used only in the final stages of the concrete working process.
