g0689 13" planer
Before re-installing the knives, the cutterhead,
gib and knife must be inspected. neglecting to
inspect these components may result in damage
to the planer.
To inspect the cutterhead, gib, and knives:
1. diSConnECt planEr FroM poWEr!
2. Carefully clean the cutterhead with a rag and
with a flashlight, inspect the following:
• Make sure the threaded screw holes do
not contain wood material or sawdust.
• Make sure that the hex socket and the
threads of all cap screws are in good
condition. replace if questionable.
• Make sure any resin or glue buildup
on the cutterhead, gib, and knives is
removed so the knife and gib will sit flat
on the cutterhead.
• Make sure the knives are free of cracks.
if any cracks exist, replace both knives.
the knives on the Model g0689 planer are revers-
ible and should always be reversed or replaced as
a matched set. to avoid downtime, we recom-
mend having an extra set of knives for your planer
(Model t20803 in the grizzly catalog or website).
once the cutterhead, gib, and knives have been
inspected and prepared, install the knives.
6. depress the safety latch (shown in figure
30), then carefully rotate the cutterhead
towards you approximately ¼ turn. release
the safety latch and continue rotating the
cutterhead until the second knife is exposed
and the safety latch again engages.
7. repeat Steps 4 and 5 for the second knife.
