ADJUSTING KNIVES
When it becomes necessary to adjust the knives due to
replacement or wear, proceed as follows:
1. DISCONNECT THE TOOL FROM THE POWER
SOURCE AND REMOVE CUTTERHEAD GUARD.
2. Rotate cutterhead and loosen four screws (A) Fig.
30. NOTE: Do not overly loosen the screws (A). Loosen
one half turn or only enough so knife can slide between
locking plate and cutterhead.
3. Rotate cutterhead and engage cutterhead lock (B)
Fig. 31, on cutterhead shaft as shown. This will position
knives for proper adjustment to the outfeed table.
4. Place a straight edge (C) Fig. 31, on the outfeed table
extending out over the knife as shown. Using wrench (D)
supplied, turn screw (E) until knife just touches straight
edge. Adjust knife at far end of cutterhead in the same
manner turning screw (F). Tighten four screws (A) Fig. 30,
after adjustment is made.
5. Adjust remaining knife in the same manner and
MAKE SURE CUTTERHEAD LOCK (B) IS DISEN-
GAGED AFTER ADJUSTMENT IS COMPLETED AND
REPLACE CUTTERHEAD GUARD.
