KNIFE SETTING OR REPLACEMENT
To perform this task correctly, all components
(knives, screws, bars and cutterhead) need to be
thoroughly clean and free of any debris or pitch.
MODEL 30-200:
Properly setting all 3 knives is essential to obtain accurate
work results. Knives will also last longer and will keep their
sharpness longer by equally sharing the cutting workload.

WARNING
!
MAKE CERTAIN THAT THE MACHINE IS
DISCONNECTED FROM THE POWER SOURCE
BE ExTREMELY CAREFUL THAT YOUR HANDS
DO NOT COME IN CONTACT WITH THE KNIVES.
THE KNIVES ARE VERY SHARP. WEAR PROTECTIVE
GLOVES WHEN HANDLING THE KNIVES.
To obtain the best adjustment results of the knives, it is
imperative to number the knives and grooves on the
cutterhead. With a permanent felt pen, across the groove
and over the knife, draw 1 line for #1 knife, 2 lines for #2
knife and 3 for the #3 knife. This will enable you to go back
and forth from one knife to the other to make fine
adjustments and be certain that all knives were tightened
properly.
The straight knife cutterhead offers 2 methods of
adjustment: springs and jack screws
(Fig. 29)
.
This provides you with 2 options for setting the knives, so
you can decide which method works best for you.
1. Turn off and disconnect the jointer from power source.
2. To have full access to the cutterhead and knives,remove
the cutterhead guard.
3. Remove the fence to have access to the upper pulley, so
you can rotate the cutterhead to access all of the knives.
4. Using a wrench, choose a first knife and loosen (but do
not remove) all the gib bolts
B (Fig. 30)
.
Start in the center and alternate sides. If replacing, loosen
the bolts until the knife can be removed and install the
new knife.
