Setup & Operation
2.15 Cutting The Log
The following steps guide you through normal operation of the Wood-Mizer sawmill.
1. Once the log is placed where you want it and clamped firmly turn the key switch to the
ACC position.
2. Determine where to make your first cut. The sight gauge and the blade height scale will
help you to do this (
See Section 2.17
and
See Section 2.18
). Set the blade to the desired
height with the up/down switch. Make sure that the blade will clear all side supports and
the clamp. Adjust the outer blade guide to clear the widest section of the log by moving
the blade guide toggle switch.
3. Make sure all covers and guards are in place. Start the engine. Engage the clutch/brake
lever to start the blade spinning.
4. Start the water lube if necessary to prevent sap buildup on the blade.
See Section 2.19
.
5. Feed the blade into the log slowly
(
See Section 2.14
). Once the blade completely enters
the log, increase the feed rate as desired. Always try to cut at the fastest speed you can
while keeping an accurate cut. Cutting too slowly will waste blade life and lower produc-
tion!
6. As you get to the end of the log, slow down the feed rate. When the teeth exit the end of
the log, turn the feed rate all the way down and disengage the clutch/brake lever. Remove
the slab that you have just cut from the log.
7. Use the carriage fwd/rev switch to return the carriage to the front of the mill. Always dis-
engage the blade before returning the carriage for the next cut.
8. Repeat until the first side of the log is cut as desired. Set aside the usable flitches (boards
with bark on one or both sides). You can edge them on the mill later.
9. Lower the toe boards, if they were used. Use the hydraulic levers to release the clamp
and engage the log turner. Turn the log 90 or 180 degrees. Make sure the flat on the log is
placed flat against side supports if turned 90 degrees. Make sure it is placed on bed rails
if turned 180 degrees. If the log was turned 90 degrees and you are using toe boards to
compensate for taper in the log, raise the front or rear toe board again on the second side
of the log until the heart is parallel with the bed.
10. Repeat the steps used to cut the first side of the log until the log is square. Cut boards
from the remaining cant by adjusting the blade height for the thickness of boards that you
want.
Example: Remember that the blade cuts a 1/16 - 1/8" (1.6-3.2 mm) wide kerf. If you want
1" (25.4 mm) thick boards, lower the carriage 1 1/16 - 1 1/8" (27-28.6 mm) for each board.
