Replacing Blades - Grizzly G0828 Owner's Manual

Replacing Blades

Both upper and lower blades are identical and
have two cutting edges, so that if one cutting edge
becomes dull, you can reverse the blade and use
the fresh, sharp cutting edge. Both blades can be
resharpened as an alternative to replacing.
If both cutting edges are dull, re-sharpen the
blades on a surface grinder and make sure they
stay flat along their entire length. If the blade
becomes too thin and the cap screws that secure
it extend beyond the opposite side of the cutting
edge, you will need to replace it. If the blade is
nicked or damaged, replace it. Contact Grizzly
at (800) 523-4777 or online at grizzly.com to pur-
chase Part No. P08280010 (Model G0828), or
P08290010 (Model G0829). Keep an extra set of
blades on hand to avoid downtime.
