ADJUSTING KNIVES

When it becomes necessary to replace or adjust the knives due to replacement or wear:

The knives are sharp.

Disconnect machine from power source.

1. Remove cutterhead guard.

2. To replace a knife, disengage the cutterhead lock (A) Fig. 30. Rotate cutterhead, loosen four screws (B) and remove

bar and knife. Insert new knife and replace bar and slightly tighten four screws (B).

BE EXTREMELY CAREFUL THAT YOUR HANDS DO NOT COME IN CONTACT WITH THE KNIVES.

3. To adjust the knives, make sure the cutterhead lock (A) Fig.30 is not engaged. Make sure screws (B) are not overly

tightened. Loosen each one half turn or only enough so knife can slide between locking plate and cutterhead.

4. 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.

5. Place a straight edge (D) Fig. 31, on the outfeed table extending out over the knife as shown. Using wrench (C)

supplied, turn screw (E) until knife just touches straight edge. Adjust knife at near end of cutterhead in the same

manner turning screw (F). Tighten four screws (B) Fig. 30, after adjustment is made.

NOTE: Make sure cutterhead lock (B) is disengaged after adjustment is completed and replace cutterhead guard.
