ADJUSTINg THE kNIVES
To reduce the risk of injury, turn unit off
and disconnect it from power source before installing
and removing accessories, before adjusting or when
making repairs.
An accidental start-up can cause injury.
1. Remove the top cover of the planer to expose the
cutterhead.
2. Check all four knives for proper setting using a knife
gauge (A) Fig. 20. When the gauge (A) is placed on
the cutterhead, and the bottom of the two roll pins -
one of which is shown at (B) - are against the edge
of the slot (C) opposite the knife, the knife should
barely contact the bottom of the gauge (D).
3. To adjust, loosen the knife locking bar of each of
the four knives by turning the knife locking screws
(E) Fig. 20 in the locking bar just enough to relieve
stress in the cutterhead, but not enough to disturb
the setting of the four knives.
4. To reset individual knives, loosen the locking screws
(E) Fig. 20 of that knife by turning them in the
locking-bar. When the knife locking-bar becomes
loose, the lifter springs under the knife will push the
knife until it contacts the bottom of the gauge (D).
Snug the knife locking-bar by lightly backing the
locking screws (E) against the knife slot.
IMPORTANT:
Loosely tighten the knife in the slot only
enough to hold it in position.
5. To reset additional knives, repeat
STEP 4
.
6. After all knives are set, back out and tighten the locking screws - three of which are shown at (E) Fig. 20 - against
the slot. Start with the end screws first and tighten the screws on alternate sides toward the center screws until
the knife is securely held in the cutterhead. Tighten the remaining three knives in the same manner.
REPLACINg THE kNIVES
To reduce the risk of injury, turn unit off and disconnect it from power source before installing and remov-
ing accessories, before adjusting or when making repairs.
An accidental start-up can cause injury.
When you remove knives for sharpening or replacement, wear gloves and take extreme care.
These knives are very sharp.
1. To remove the first knife, loosen the knife locking bar, by turning the locking screws - three of which are shown at
(E) Fig. 20 - into the knife locking bar. Remove the locking bar, knife, and springs located under the knife.
2. Remove the remaining three knives in the same manner.
3. Thoroughly clean the knife slots, knife bars, springs, and screws. If the threads appear worn or stripped, or if the
heads are becoming rounded, replace them.
4. Inspect the cutting edge of the knives for nicks or a wire edge. Hone the knives slightly using a stone or, if the
knives are to be sharpened, maintain a cutting angle of 40 degrees.
5. Insert the springs, knives, and knife locking bars into all four slots in the cutterhead. Push the knives down as far
as possible, and back out the locking screws - three of which are shown at (E) Fig. 20 - just enough to hold all four
knives in the cutterhead.
6. Adjust all four knives as explained in "ADJUSTING THE KNIVES" section above.
