Basic Saw Operations
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 (Figure 23). (Wood can have a maxi-
mum height of 3-1/4". Check that head
assembly does not interfere with auxiliary
fence.)
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. Attach the auxiliary fence using three (3) 1/4"
flat head machine screws. Make a full depth
cut to create the blade slot. Check for inter-
ference between the auxiliary fence and the
lower blade guard. Make adjustments as
necessary.
Check for interference from any
components.

long shackle of up to 1/4" in diameter (not provided

rized use.
