Replacing Knives

Your thickness planer is supplied with double edged
knives. Knives should be replaced or turned 180° to the
unused edges whenever they become dull or nicked.
Keeping a spare set of knives on hand is recommended.
Knives should always be replaced as a matched set.
CAUTION: Exposed knives are sharp and could
injure you. To reduce the possibility of injury pro-
tect your hands with gloves or shop rag and use
the knife tool when removing or installing knives.
1. Be sure the switch key is removed and the unit is
unplugged from the wall receptacle.
2. For easier access to the cutter head/knife assembly
remove the upper cover. See illustration.
3. Loosen the two dust chute knobs and remove the
dust chute.
NOTE: When dust chute is removed the cutter head
lock will engage when the head is rotated. Do not
operate thickness planer without the dust chute in
place, or your planer will be damaged
4. Rotate the cutter head until the lock engages. This
will correctly position a knife and its seven knife lock
screws.
WARNING: To reduce the risk of injury from acci-
dental contact with the exposed knife, when turn-
ing the knife lock screws, lay a folded shop rag
over the knife or wear a glove.
5. Carefully loosen all seven knife locking screws.
NOTE: Move wrench left to right to loosen screws.
6. Use the notched end of the Magnetic Knife Handling
Tool to remove the knife by hooking the notch over
the end of the knife and pulling straight out.
7. Use the magnet on the Magnetic Knife Handling Tool
to help remove the knife.
8. If you are changing to the second edge of the knife,
rotate the knife "end for end" keeping the same flat
side down. This will correctly position the knife to
reinstall. Look closely at the cutter head side view
making sure the knife is installed as pictured. Knives
should be cleaned of gum and pitch before reinstall-
ing.
WARNING: To reduce the risk of thrown blades and
other cutter head parts make sure the knife lock
bar containing the seven knife lock screws is posi-
tioned as shown in the cutter head side view pic-
ture.

tion the second knife.
