SECTION 1 SAFETY
This symbol calls your attention to instructions concerning your personal safety. Be sure
to observe and follow these instructions. This symbol accompanies a signal word. The
word DANGER indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury. WARNING suggests a potentially hazardous situation
which, if not avoided, could result in death or serious injury. CAUTION refers to potentially
hazardous situations which, if not avoided, may result in minor or moderate injury to per-
sons or equipment. Read all safety instructions before operating this equipment and
observe all safety warnings!
1.1 Installation and Maintenance
DANGER! On electric mills, hazardous voltage inside the
disconnect box, starter box, and at the electric motor can
cause shock, burns, or death. Disconnect and lock out
power supply before performing debarker installation! Fol-
low all applicable electrical codes.
DANGER! Make sure all electrical installation, service
and/or maintenance work is performed by a qualified elec-
trician and is in accordance with applicable electrical codes.
Failure to do so will result in serious injury or death.
DANGER! Before performing any service to this equip-
ment, turn the key to the OFF position, remove the key, and
disconnect the sawmill battery ground terminal. Failure to
do so will result in serious injury or death.
WARNING! Before replacing the debarker blade, move the
sawmill blade guide arm in front of the sawmill blade to
cover the blade teeth. Failure to do so may result in serious
injury or death.

1.2 Operation and Towing
DANGER! Make sure all guards and covers are in place
and secured before operating the debarker option. Failure
to do so may result in serious injury.
DANGER! Keep all persons out of the path of moving
equipment when operating the debarker. Failure to do so
will result in serious injury.
DANGER! Always remove the key from the control panel
before preparing the debarker for towing. Failure to do so
may result in serious injury.
WARNING! Debarker is ON when warning light is on. DO
NOT disconnect the warning light. Doing so may result in
serious injury.
WARNING! If the debarker continues to run with the key
switch in the OFF position, remove the negative battery ter-
minal from the battery post.
DO NOT continue to operate the mill if the main key switch
does not control debarker operation. Doing so could result
in serious injury. Call Wood-Mizer customer service for
more information.

SECTION 2 DEBARKER INSTALLATION
DANGER! On electric mills, hazardous voltage inside the
disconnect box, starter box, and at the electric motor can
cause shock, burns, or death. Disconnect and lock out
power supply before performing debarker installation! Fol-
low all applicable electrical codes.
DANGER! Before performing any service to this equip-
ment, turn the key to the OFF (0) position, remove the key,
and disconnect the sawmill battery ground terminal. Failure
to do so will result in serious injury or death.
CAUTION! Due to various design changes and past retro-
fits and options, you should very carefully look your mill
over to determine Debarker compatibility before beginning
Debarker installation.
2.1 Debarker Installation
DANGER! Always disengage the blade and shut off the
sawmill engine before installing the debarker. Failure to do
so will result in serious injury.
IMPORTANT! Sawmills are equipped with pre-drilled
Debarker mounting holes. Verify hole locations before
beginning Debarker installation. Proper hole location is
imperative for safe and effective Debarker operation.
1. Open the blade housing cover.

2. Assemble the debarker to the sawmill saw head. Align the mounting block holes and the
two debarker mounting holes in the saw head. Use the provided hex head bolts, split lock
and flat washers to secure in place. Make sure the debarker is square to the saw head
before tightening.
See Figure 2-1.

3. Assemble the debarker cutting head to the mount plate on the frame.
Use the four provided bolts and split lock washers to mount the cutting head to the
debarker frame. Use the lower set of four holes in the head mounting plate. The upper set
of holes are provided in the event the cutting head needs to be adjusted further down
than the slotted motor mount holes will allow.
See Figure 2-2.

4. Install the blade guard bracket and flexible debris guard to the debarker head with two flat
washers, lock washers, and hex head bolts. Be sure the bottom of the debris guard is
even with the bottom of the debarker blade.

2.2 Harness Installation
DANGER! Before performing any service to this equip-
ment, turn the key to the OFF (0) position, remove the key,
and disconnect the sawmill battery ground terminal. Failure
to do so will result in serious injury or death.
IMPORTANT! Avoid pinch and pivot points, unnecessary
wire bending and open spaces where the wire could get
caught by a log, etc. If you have any questions, call
Wood-Mizer customer service.
1. Route the harnesses through the saw head frame hole as shown. Continue routing the
long blade motor wire harness (large wires/ring terminals) inside the debarker frame
through the three holes with grommets.
