“Zero Out” the Display (see figures 40 & 41)
When using the digital carriage for the first time, it is normally
required to slide the fence against the blade (with the digital
carriage attached) in order to “zero out” the display – thereafter,
any movement of the fence away from the blade will be shown
on the carriage display.
To “Zero Out”:
1) Connect fence to digital carriage
2) Lift fence lock handle
3) Lift up the plastic side blade guard until it ‘clicks’ into it’s up
position – then lift and hold up the pawl of the anti-kickback
device (careful – teeth are sharp!)
4) Slide fence (with carriage) until it contacts the raised saw
blade, then lock down the fence handle
5) Press RESET button until the “0” setting is shown
6) Unlock fence handle - move fence away from blade, and
lower pawl and side blade guard.
Stop fence movement when the desired setting is displayed –
always push down fence lock handle before starting cut.
Note 1: For accuracy, the carriage needs to separately “zero
out” for each side of the blade – If the carriage is set for rip cuts
to the right of the blade, and the user switches to make rip cuts
to the left of the blade, the “zero out” procedure will have to be
done again.
Note 2: The digital carriage can be reset to zero at any position
of the fence – this may be useful when adding or subtracting
from a preset position.
Example: (display set in the 1/32 INCH mode). If the fence and
digital carriage is moved to where it shows 6-3/32 inches (or any
positive value) and the user wishes to move the fence from that
spot to be 3/4 inch less – the user can “zero out” the display so
that it shows 0/32 inches and then move the fence to the left until
the display shows “- 3/4 INCH”; or if the user wishes move the
fence to be 3/4 inch more, the user can “zero out” the display so
it shows 0/32 and move the fence to the right until the display
shows “3/4 INCH”. However, for the next new setting, the user
will have to RESET and “zero out” (against the blade).
Display Changes – Right of ”0”
The display numbers will go up when moving the carriage to the
right of the”0”.
Display Changes – Left of ”0”
The display numbers will go up (and the minus sign “-“ will
appear) when moving the carriage to the left of the ”0”.
