Knife Replacement - Grizzly G0689 Owner's Manual

Knife Replacement

The cutterhead knives on the Model G0689
are extremely sharp. Brushing your finger
along the edge can result in a severe cut.
Take extreme caution when doing any of
the adjustments involving the cutterhead
knives. Wear heavy leather gloves any-
time it is necessary to manually rotate the
cutterhead assembly.
To maintain accurate and consistent plan-
ing results, we do not recommend sharpen-
ing the knives. Instead, replace both knives
when they get dull.
the condition of the knives on the Model g0689
planer will affect the precision of the cut. during
operation, watch for the following signs of dulled
knives.
• raised grain occurs as a result of dull knives
hammering at the surface of the wood.
• a "fuzzy" appearance on the surface of the
wood occurs as a result of dull knives tearing,
rather than cutting the wood fibers.
• grooves occur as a result of nicks along the
knife edge.
• difficulty feeding the workpiece into the
planer.
if any of these signs become apparent during use,
the knives must be reversed or replaced. do not
attempt to sharpen the knives.
