KNIFE SETTING

The 3 blades in your jointer are factory set, and there-
fore should be set to the right height and parrallel to the
cutterhead. If for some reason you need to adjust the
blades
These are the steps to follow.
1. Disconnect machine from power source.
2. Lower infeed table.
3. Remove cutterhead guard.
4. Lay a steel straight edge along the outfeed table so
it extends across the cutterhead Fig. 13. When the
cutterhead is turned by hand, the blades should
just touch the bottom of the straight edge.
5. If the knives are high or low at the ends, loosen the
four (4) screws that hold the knife locking bars in
place Fig. 12 (A), and turn the knife raising screws
Fig. 13 (A), clockwise to raise the knives, and anti
clockwise to lower them. When lowering the knives
you may need to push them down gently onto the
raising screws with a piece of wood after screws
are turned.
6. Tighten locking bar screws. Fig. 12 (A)
7. Repeat for all three knives. It is important that they
are the same height.
8. Replace cutterhead guard.
