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 poten-
tially hazardous situations which, if not avoided, may result in minor or moderate injury to
persons 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 bell sounds. DO
NOT disconnect the warning bell. 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.
The Debarker Option may be installed to most sawmills with the required up/down chains
and 60 amp or larger alternator systems.
See Table 2-1. Look at your sawmill up/down chains to verify they are the proper style
for use with the Debarker Option. Refer to the chart below to determine if the Debarker
Option may be installed on your specific sawmill.

comments.
"USA" should be stamped into the side plates of the chain. If it is not, you will
need to replace the existing chains with the proper specified chains. If you did
not receive replacement chains with your Debarker order and find that you need
them, call Wood-Mizer Customer Service at 1-800-525-8100.Do not proceed
with Debarker installation or further operation until your mill is equipped
with the correct up/down chains.
#50-2 Yes The Debarker Option can be installed on any sawmill equipped with #50-2
up/down chain (after 3/97).

2.1 Debarker Frame Mounting Holes
IMPORTANT! Later 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.
Five holes in the sawmill saw head are required to mount Rev. A.00 - D.02 debarkers.
Seven holes in the sawmill saw head are required to mount Rev. D.03 and later debark-
ers.
See Figure 2-1. If your sawmill has no pre-drilled holes, use the provided template as a
guide to drill the required holes.
1. Locate the template against the top of the c-frame. Move the harness and water lube
hose out of the way and locate the template against the side of the c-frame. Locate the
bent tab against the c-frame vertical tube. Clamp the template in place to secure it.
2. Use a 13/32" drill to start holes at locations A and B. Use a 7/16" drill to start holes at loca-
tion C. Remove the template and drill holes through completely. NOTE: Debarkers prior to
Rev. D.03 only require two holes at location B. The template should match the mounting
configuration of your debarker.

2.2 Debarker Control Mounting Holes
See Figure 2-2. The model and age of your sawmill will determine where you need to
install the debarker control. If you have a standard mill manufactured after June 1996, or
any super series mill, use the location D on the motor support tube shown in the main
portion of the figure. If you have a standard mill manufactured during or prior to June
1996, use the alternate location D on the motor mount plate shown in the figure inset. Drill
two 9/32" diameter holes at the locations shown.

2.3 Debarker Control Installation
NOTE: Loose installation hardware is located in the bag
assembly.
1. Assemble the control box to location D (or alternate location D, as determined by mill
type).
2. If you have a standard sawmill manufactured after LT30 rev. F6, LT40 rev. F7, or
LT30HD/40HD rev. F9, or if you have any revision super series sawmill:
See Figure 2-3. Install the mounting bracket as shown and use the four 1/4-20 x 3/8”
socket button head screws to secure the bracket to the control box. Use the provided
1/4-20 x 2 3/4” hex head grade 2 bolts and 1/4-20 hex lock nuts to secure the box assem-
bly to the mill.

If you have a standard sawmill manufactured prior to LT30 rev. F6, LT40 rev. F7, or
LT30HD/40HD rev. F9:
See Figure 2-4. Install the four 1/4" SAE flat washers and vibration isolators to the control
box and tighten by hand. NOTE: Install and tighten one isolator at a time, placing the 1"
isolators diagonal to each other and the 3/4" isolators diagonal to each other.
DANGER! To prevent possible damage or injury, be sure
the enclosed vibration isolators are installed to the
Debarker control box before Debarker use on any of the
mill revisions listed below.
Position the mounting bracket as shown and use four 1/4-20 self locking nuts to secure
the bracket to the control box.
Use the provided 1/4-20 x 1” hex head grade 2 bolts and 1/4-20 hex lock nuts to secure
the box assembly to the mill.
