SECTION 3.3: BLADE SELECTION
Selecting the proper blade for the application will have a dramatic effect on
machine efficiency. If a blade is too wide for the application, there may not be
enough pressure on the blade to stay under the material to be removed. If the
blade is too narrow, the machine may not be removing the maximum material it is
capable of in a single pass.
Based on information about a particular job, start with the widest blade that may
be appropriate for removal. Make a test pass to determine if the blade will stay
under the material. If so, continue with this selected blade. If removal of the
material is relatively easy, consider moving to a larger blade. If it is difficult to
stay under the material, move to a narrower blade.
Always wear leather gloves and use caution when handling blades.
In general, flat blades should be used for scraping glues, mastics, epoxies and
thinsets. SEE FIGURE 3.3.1.

For carpet, rubberized and elastomeric coatings, a carpet blade should be
utilized. The 90° wings on each end of the blade will help keep the removed
material manageable. SEE FIGURE 3.3.2.
