Adjust the bottom saw head stop bolt all the way down. Move the saw head down until Accuset displays 3/4” and adjust the bottom saw head stop bolt up until it just touches the saw head.
Setup & Operation Control Setup 2.1.4 Auto-Bump (Rev. E.O4+ Only) By default, the Auto-bump feature is not activated. To activate Auto-bump, push the Up button to enter Configuration Menu #1. Choose “Other Settings” button from Configuration Menu #1. Push the “Change Lan- guage”...
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”.
Page 47
Setup & Operation Control Setup See Figure 2-8. You can change other settings for the Accuset including the language used on the display, the unit of measure, PID values and analog limits. These settings are found in Configuration Menu 2. To display Configuration Menu 2, push the Up button while in Manual Mode to display Configuration Menu 1.

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.
Page 56
Setup & Operaton Mode Selection head is being raised. The Increment Settings buttons work in the same manner as 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.
Setup & Operation Using Auto-Down Mode Using Auto-Down Mode See Figure 2-14. In Manual Mode, Cut first face as Switch to Manual Mode position blade desired in Auto-Down and position blade for trim cut. Switch Mode then turn for trim cut. Switch to to Auto-Down and log.

(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 2.1.5).
