Press At 12 Inches (or 305mm in metric mode). The Accuset control should indi-
cate the actual position of the blade above the bed rails. To check this setting, move
the saw carriage so the blade is positioned above a bed rail. Raise the saw head
until the blade is positioned 12" (305mm) by actual measurement from the bed rail.
Measure from the top of the bed rail to the bottom of a down-set tooth of the blade.
While in Manual Mode, push the Up button to enter the Configuration Menu.

1.1.3 Other Settings
Set Kerf. The Kerf setting is optional. The default kerf setting is ’0’. You can use the kerf
setting to automatically factor the blade thickness into the increment setting. Factoring the
kerf into the program will allow you to saw boards that are the actual thickness of the pro-
grammed increment. For example, if kerf is set to ‘0’ and you have programmed incre-
ments of 1 1/8”, the resulting boards will be about 1 1/16” thick because Accuset did not
factor the thickness of the blade. If you enter an accurate kerf value, the resulting boards
will be 1 1/8”. Whether or not to use the kerf setting is dependant on your sawing prac-
tices and application.
See Figure 1-5. While in Manual Mode, push the Up button to enter the Configuration
Menu. Press the “Set Kerf” button to display the menu below.
See Table 1-1. Recommended kerf settings for various blades are provided below.
These kerf setting values assume the teeth of the blade are set per factory specifications.
If you prefer, a nominal kerf value of .125 (3 mm) can be entered and should be accurate
enough for most applications.
Push the Set Kerf button and use the Up and Down buttons to adjust the kerf setting.
Pushing the Up and Down buttons simultaneously will scroll the kerf faster. Push the
Save button to store the new Kerf Setting. If you don’t use the Kerf Setting, be sure to
include the thickness of the blade in your increment settings as described in Section 1.2
Mode Selection.

1.2 Mode Selection
See Figure 1-8. To select an Accuset mode, press the desired Mode Select button
(Auto-Down, Auto-Up or Pattern) located under the display. Press the Manual Mode
Select button to return the control to Manual Mode.
Manual Mode - This mode allows you to use the up/down function of the sawmill as you
normally would without the Accuset option. The Current Blade Height will continue to be
displayed by the Accuset control.
Auto-Down Mode - This mode references the current blade height and allows you to
choose an increment to move the blade down. The Accuset will automatically move the
saw head down and stop at the next increment when you push the drum switch down.
You can store sixteen different increment levels using the four numbered Increment Set-
tings buttons. Each button stores four adjustable increment settings. Push button #1 once
for setting #1. Push button #1 a second time for setting #5, etc...
Auto-Up Mode - This mode references the current blade height and allows you to choose
an increment to move the blade up. The Accuset will automatically move the saw head up
and stop at the next increment when you push the drum switch up. Auto-Up mode is pri-
marily used to raise the saw head in large increments when preparing to cut a new log or
log that has been turned. This allows the operator to raise the saw head without having to
hold the drum switch up, freeing the operator to perform other functions while the saw

described in Auto-Down Mode.
NOTE: The sixteen increment settings apply to Auto-Down
AND Auto-Up modes. If you change a setting in Auto-Down
mode, it will also change when you are in Auto-Up mode.
Pattern Mode - This mode references the bed surface and allows you to program up to
six different increments calculated up from the bed. The sixth (top) increment repeats
itself up to the upper limit of the saw head travel. The bottom increment indicates the size
of the remaining cant when the pattern is complete.
Reference Mode - This mode allows the operator to program up to four pre-set locations
along the saw head travel. The factory default settings are at the bottom (1”), the location
where the saw head is calibrated (12”), a location midway between the calibration and the
top (24”), and the top (31”).

To change an Increment Setting, select the desired setting number and push the Up or
Down buttons until the desired Increment Setting is obtained. Remember to include blade
kerf in your setting (i.e. If you want the finished boards to be 1" thick, set the increment to
1 1/8" to allow for typical blade kerf). The amount of kerf will depend on the thickness and
tooth set of the blade you are using. The Accuset can be programmed with an automatic
kerf setting if desired (See Section 1.1.3).
When you change and increment value, it is only temporarily stored. If the control is
turned off, the settings will return to the factory defaults unless the new values are saved.
To save the new increment setting, push the Manual Mode then push the Up button. The
Configuration Menu will be displayed. Choose Save to enter the Save Settings menu,
then push Save.
Example: Verify you are in the Auto-down mode. To store 1 1/2" increment to the #1
increment setting, push button #1. Push the Up or Down arrow button to raise or lower the
increment on the screen to the desired setting. Push the Manual button, then the Up
arrow to display the Configuration menu. Now push the Save button to enter the Save
Settings menu. Push the Save Settings button. Your program is saved. You can program
multiple buttons and save them all at one time.

raise the saw head and return the carriage to the front of the log.
Push the up/down drum switch down and release. The saw head will automatically
bypass the setting where the first cut was made and stop at the next setting determined
by the increment you have chosen.
Make a cut, raise the saw head and return the carriage for the next cut. Push the up/down
drum switch down and release. The saw head will stop at the setting for the next cut.
Repeat this procedure down this face of the log as desired.
Turn the log as you normally would and push the Manual Mode button to place the
Accuset in Manual Mode.
Position the saw head for the trim cut and push the Auto-Down button to return to
Auto-Down Mode. Make the trim cut, raise the saw head and return for the next cut. Use
the same procedure as described above to cut each side of the log until done.
NOTE: Anytime a trim cut is necessary, you can push the
Manual button to enter Manual Mode. Position the saw
head for the trim cut and push the Auto-Down button to
return to Auto-Down Mode. Accuset will reference the new

Starting with a new log, position the saw head at the front end of the log.
Push the Pattern button under the display. Pattern Setting #1 is the factory default.
Choose the desired pattern setting (1 - 16) by pushing the appropriate Increment Setting
button.
In Pattern mode, a list of six increments is shown on the display. These increments are
referenced from the bed rail. The bottom increment represents the distance from the bed
rail for the last cut. Each increment in the list can be adjusted as desired. The top incre-
ment repeats as necessary depending on how high you raise the saw head.
As you raise or lower the saw head, symbols in the pattern increment list indicate where
the blade is located in reference to the pattern. When the blade is above the top setting a
^ symbol appears next to the top increment to indicate you are in the repeating top incre-
ment. After you lower the blade and reach the last top increment, a + symbol will appear
to indicate you are close to the next setting. When the blade reaches the increment set-
ting, a - symbol will appear next to that setting.
To change any of the six pattern increments, push the +/- Drop button (below the pattern
increment list) to scroll to the desired increment. The increment that is active is high-
lighted. As you scroll to each increment, the previous increment setting will automatically
be copied to the remaining increments below. Push the Up or Down buttons until the
desired increment is obtained. Remember to include blade kerf in your setting (i.e. If you
want the finished boards to be 1" thick, set the increment to 1 1/8" to allow for typical
blade kerf). The amount of kerf will depend on the thickness and tooth set of the blade
you are using. The Accuset can be programmed with an automatic kerf setting if desired
(See Section 1.1.3).
Push the +/- Drop button to move to the next pattern increment and adjust as desired.
After the bottom increment setting is adjusted as desired, push the Manual Mode button
then push the Up button. The Configuration Menu will be displayed. Choose Save to
enter the Save Settings menu, then select Save.
Example: To edit the pattern increment settings for the #4 pattern setting, push Increment
Selection button #4 once to display pattern setting #4 (the factory default value for pattern
setting #4 is 1 3/4"). Push the +/- Drop button to enter pattern edit mode. The top pattern
increment is now highlighted. Push the Down button to adjust the setting to 1 1/8". While
pushing the Down button, push the Up button to scroll faster. When you get close to 1
1/8", release both buttons. Push the Down button to fine tune the setting to exactly 1 1/8".
Push the +/- Drop button again to move the next pattern increment. The setting will auto-
matically be copied from the previous setting to 1 1/8” for all the remaining increments
below. Exit pattern edit mode by pushing the Manual button. Save the new pattern setting
by pushing the Up arrow button to enter Configuration Menu #1. Press the Save button to
