Making an Auxiliary Fence
Check for interference be-
tween auxiliary fence and
saw head components by performing a dry
run. Fence interference can prevent proper saw
operation and cause injury and/or tool damage.
Be aware of the path of the
saw blade. Make a dry run
with the saw OFF by conducting a simulated
cutting cycle, and observe the projected path
of the saw blade. Keep hands at least six (6)
inches (152mm) away from the projected path
of the saw blade.
Certain types of molding need a fence face ex-
tension because of the size and position of the
workpiece. Holes are provided in the fence to
attach an auxiliary fence. Only use the auxiliary
fence with the saw in the 0° bevel position.
1. To create an auxiliary fence (Fig. 34), place
a piece of wood against the fence (Fig. 31,
11). Wood can have a maximum height of
3-1/4" (83mm). Check that auxiliary fence
assembly (Fig. 34) does not interfere with
the saw head assembly (Fig. 33, 24).
2. Mark the locations of the support holes on
the wood from the back side of the fence.
3. Drill and countersink the holes on the front
of the support board.
4. To fasten from front of fence: Attach (each)
auxiliary fence using two (2) 3/16" (M5) flat
head machine screws (Fig. 34). With 3/4"
(19mm) auxiliary fence, use 1-1/2" (38mm)
long screws. Secure behind metal fence with
washer and machine nuts.

To fasten from back of fence: With 3/4"
(19mm) auxiliary fence, use 1/4" (M6) round
head wood screws (3/4"/20mm long). Drill
four pilot holes through auxiliary fence and
run screws from rear of metal fence.
5. Make a full depth cut to create the blade
slot. Check for interference between the
auxiliary fence (Fig. 34) and the lower blade
guard (Fig. 33, 22). Make adjustments as
necessary.
6. For best splinter-free cuts, use the chop cut
method.
7. When making slide cuts, the center must be
notched out per pattern (Fig. 35).
