INCRA TS-LS
Metric Extended Capacity Instructions
Installing your new fence system with the TS-LS Owner’s Manual will provide 810mm of right-side
ripping capacity. These instructions will increase that capacity to 1320mm on most saws.
Note: When installing the longer 92” rails, the only departure from TS-LS Owner’s Manual is that
the right-hand end of the rails should be 1650mm from the blade instead of 45” (page 5, step 5).
Complete the entire installation and set the LS positioner’s steel primary scale before using these
instructions to set up the system for extra capacity.
1. Slide the “floating EL” stops from Hardware Pack B-05 into the T-slots on the bottom of the
main rails and tighten them against the edges of the base clamps that are nearest the blade
(see page 12 of the TS-LS Owner’s Manual). These stops will be used to position the base
on the rails for cuts made from 0 – 810mm wide.
2. If you haven’t already done so, install the rail support legs 200 – 400mm from the ends of the
rails. Set the levelers so the ends of the rails don’t appear to rise or sag when sighting down
the rail’s length.
3. Set the fence 510mm from the blade using the steel scale and fully lock the red lever on the
LS positioner. Leave the ends of the fence unlocked.
4. Clamp blocks of scrap wood onto the infeed and outfeed main rails so they rest gently against
the face of the fence. (Fig. 1)

5. On the dual-pilot rectangular nuts that hold the base clamping knobs, loosen the small set
screws with an Allen wrench so the knobs and base assembly can slide freely up and down
the rails. A drop of Loc-tite on the threads of the set screws will hold them in place in the nuts
if you choose to leave them loose.
6. Unlock the LS positioner and slide the base assembly toward the end of the rails. Fully lock
the red lever when the 0mm mark on the steel scale shows under the cursor. This moves the
base exactly 510mm to the right from its original position. (Fig. 2)

7. With the fence still touching both wooden blocks and the base assembly resting naturally on
the rails, tighten the base clamping knobs, and lastly tighten a pair of stop bolts against the
edges of the base clamps that are furthest from the blade. (Fig. 2)
Setting the extended capacity scales
1. Slide the Lexan 1230 - 810mm scale and 820 - 400mm scale into an empty slot in the
carriage so that the ends of the scales overlap.
2. To calibrate the new scale, unlock the carriage and slide the fence until 490mm on the steel
scale shows under the hairline cursor, lock the carriage, and then slide the Lexan scale to
read 1000mm under the cursor. Next, reposition the fence to 190mm on the steel scale, lock
the carriage, and slide the remaining Lexan scale to read 700mm under the cursor.
At any given fence position, the difference in the readings between the steel scale and the
extended capacity scale will always be 510mm, making it easy to spot-check the calibration of
the Lexan scale.
When the setup is complete, you can loosen the base clamping knobs and slide the base
assembly between the two sets of rail stops as needed, enabling you to use the TS-LS in the
0mm to 810mm range with the base assembly against the “EL” stops and the 510mm to 1320mm
range with the base against the second stops near the ends of the rails. A light coating of paste
wax on the rails periodically will keep everything sliding smoothly.
