SCORPION J075 - Knife Setting; Adjustment Springs; Jack Screws; Helical Insert Setting

Helical Insert Setting (HC models only)
Helical cutterhead inserts do not need to be set like
traditional jointer knives, but as they become dull or
nicked, it will be necessary to rotate the inserts to pro-
vide a fresh cutting edge, or replace them. Before ad-
justing blade inserts, unplug the machine, then remove
the cutterhead guard and fence to provide access to the
cutterhead (H).
H
Jack Screws
Set the gauge on the cutterhead, then adjust the knife’s
position using an allen key (G) until the knife just touch-
es the center pad of the gauge on either side while its
feet rest on the cutterhead and tighten the gib bolts to
secure the knife in place. Repeat for the 2 other knives.
Adjustment Springs
Push the knife down with the gauge so that the knife’s
edge is touching the center pad of the gauge (F). Hold
the gauge in place and tighten the gib bolts to secure
the knife in place. Repeat for the 2 other knives.
F
With the knives set, check and adjust the table heights
if necessary, and reinstall the fence and guard.
Knife Setting (HSS knife models)
The cutterhead on this unit is supplied with both adjust-
ment springs and jack screws, either of which can be
used to set the knives. Before setting the knives, unplug
the machine, then remove the cutterhead guard and
fence.

Before setting the knives, loosen the gib bolts (E) on the
knife to be adjusted, but do not remove the bolts entire-
ly. The bolts just need to be loosened enough to allow
knife adjustment.
