MAKING AN AUXILIARY FENCE
Certain types of molding need a fence face extension
because of the size and position of the workpiece.
Holes are provided in the fence to attach an auxiliary
fence. The auxiliary fence is used with the saw in the
0° bevel position only.
1. Place a piece of wood against the miter saw fence
(see Fig. 38). Wood can have a maximum height
of 5-1/2" (140mm). Check that auxiliary fence
assembly does not interfere with head assembly.
See dimension drawing – Fig. 39.
Check for interference
between auxiliary fence and
saw head componenents by performing a dry run.
Fence interference can prevent proper saw operation
and cause injury and/or tool damage.
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. Fasten from front of fence: Attach (each) auxiliary
fence using two (2) 3/16" (M5) flat head machine
screws. With 3/4" (19mm) auxiliary fence, use
1-1/2" (38mm) long screws. Secure behind metal
fence with washer and machine nuts.
Fasten from back of fence: With 3/4" (19mm) auxil-
iary 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.

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.
5. Make a full depth cut to create the blade slot. Check
for interference between the auxiliary fence and the
lower blade guard. 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 (see Fig. 39).
