4.6 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 #1 position.
2. Use the blade height scale to determine where to make your first cut (See Section 4.9
). The blade
height scale will help you to do this. 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.
NOTE: An optional laser sight is available to help determine where the blade will travel through the
log. See the laser sight manual for detailed operating instructions.
3. Make sure all covers and guards are in place. Push the START button to start the blade spinning.
4. Start the water lube if necessary to prevent sap buildup on the blade. See Section 4.10
.
5. Feed the blade into the log slowly (See Section 4.5
). 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 production!
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. Push te STOP button to stop the motor. Remove the slab that you
have just cut from the log.
7. Use the carriage forward/reverse switch to return the carriage to the front of the mill. Always
disengage 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, middle 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.
