Inspecting 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 con-
dition. 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.
4. Remove (6) M6-1 x 16 cap screws from gib
using 4mm hex wrench.
5. Use included magnets to remove gib, then
knife.
