MAINTENANCE
Blades Changes
Periodically the blades will become dull.
Dull blades increase the load on the planer
and can reduce its usable lifespan. When
you notice the blade performance begin to
decrease, change the blades.
1. Unplug the planer from the power
source!
2. Use extreme caution when working
around the sharp blade edge.
3. Using the open end wrench, loosen the
3 gib bolts (Figure 8) on the blade
holder.
4. Using an allen wrench, loosen the 2
set screws in the blade holder.
5. Retract the side blade guard and slide
the blade and blade holder out of the
cutterhead.
6. Using a small flat head screwdriver,
push the blade out from the end of the
blade holder.
7. Once removed, you will notice 2 cut-
ting edges on each blade. Turning the
blades reveals the new cutting edge.
8. Re-insert the blade into the blade hold-
er so the new edge will be revealed.
New blades can be purchased in the
current Grizzly Catalog as Part
#H4999.
9. Re-install the blade holder into the cut-
terhead.
10. Set a straightedge across the outfeed
sole and over the cutterhead.
11. Rotate the cutterhead so the blade
edge is at the top-dead-center of its
rotation shown in Figure 9.
Unplug the planer from the power
source before performing any main-
tenance. Failure to follow this warn-
ing could result in serious personal
injury.
