If not, sharpen blades as described in following
steps.

the flats of the spindle shaft while removing the blade
mounting bolt with a 15/16” wrench (Figure 13).
3. Use a file to sharpen blade to fine edge. Remove all
nicks and dents in blade edge. If blade is severely
damaged, it should be replaced.
