or the exquisite INCRA Double Dovetail, you’ll nd
the simplicity of our template guided joinery system
makes other joint making tools obsolete.

GETTING ACQUAINTED
Before setting up and using your new INCRA LS Positioner, take a few moments to become better acquainted with the tool by reviewing the following component descriptions and the illustration in Fig. 1.
Lead Screw Positioning Element
The LS Positioner obtains its great accuracy and
repeatability from the precision lead screw, which
positions the fence in exact increments of
(1mm metric version.)
1
/32”
Auxiliary Scale Slots
Four auxiliary scale slots are provided to allow
additional setups and cutting operations to take
place without altering the primary scale position.
Simply slide the supplied
scale into position as needed for reference.
The friction t holds the scales securely during
cutting operations. These extra slots are great
for advanced joinery using the INCRA templates.
You can even leave your most frequently used
joinery templates from the optional INCRA Master
Reference Guide & Template Library permanently
installed.

Three-Position Carriage Clamp
By pushing the carriage clamp down into the
“unlocked” position, the carriage is free to glide to
the next setting. Pull the clamp up to the center
position for micro adjusting. Pull the clamp up to
the nal position and the carriage is locked solidly
in place.
Hairline Cursor and View Windows
The large hairline cursor and view windows
provide a clear visual reference of the fence
location and span the width of the carriage top
and all ve scale slots. The factory placement of
the cursor can be moved to the rear view window
location for use on smaller router tables.
LS Base
The LS Base contains the threaded segment that
engages with and functions to locate the
carriage. It also houses the three-position carriage
clamp, the hairline cursor, and view windows.
Carriage
The reinforced square tube design of the carriage
provides the ultimate in strength and support for
your fence. It supports the lead screw positioning
element and the micro adjust knob.
Stainless Steel Primary Scale
After setting up your INCRA LS Positioner and
“zeroing” to the bit or blade, position this scale to
read 0” under the hairline cursor. Use this scale
as the primary source for readout of fence to bit or
blade distance.

Unlock the carriage clamp and carefully remove
the carriage from the LS base. For maximum access
to fence system range, locate the leading edge of
the LS base the following distance from the center
of your router collet: 19¾” for the 17” (430mm)
range model or 27¾” for the 25” range model, Fig. 2.
Center the LS Base across the width of your table. If
you have a router table top that is not long enough to
handle the full range of your LS Positioner, see the
Tip on page 6 for an easy way to extend your table
dimensions.
