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.
