WARNING: To reduce the risk of
electrical shock, fire or injury,
use only parts identical to those
identified in the parts list. Reas-
semble exactly as original
assembly to reduce the risk of
electrical hazards.

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
protect 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
The carbon brushes furnished will last
approximately 50 hours of running time or
10,000 on/off cycles. Replace both carbon
brushes when either brush has less than
1/4" length of carbon remaining. To
inspect or replace first unplug the planer.
Then turn the brush caps counterclock-
wise to remove. To reassemble reverse
the procedure. Tighten the brush caps
snugly but do not overtighten.
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 accidental contact
with the exposed knife, when
turning the knife lock screws, lay
a folded shop rag over the knife
or wear a glove.
5. Carefully loosen all seven knife lock-
ing 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 reinstalling.
