Basic Saw Operations

Auxiliary fence

Certain types of molding need a fence face exten- sion because of the size and position of the work- piece. 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.

5.Make a full depth cut to create the blade slot. Check for interference between the auxiliary fence and the lower blade guard. Make adjust- ments as necessary.

1.

Place a piece of wood against the miter saw fence

 

(Figure 22). (Wood can have a maximum height

 

of 4-1/2". Check that auxiliary fence assembly

 

does not interfere with head assembly.

 

For splinter-free cuts of molding, attach a one

 

piece wood auxiliary fence and then cut openings

 

with miter saw.

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 (each) auxiliary fence using two (2)

 

3/16" flat head machine screws. With 3/4" auxil-

 

iary fence use 1-1/2" long screws. Secure behind

 

metal fence with washer and machine nuts.

 

Alternate: With 3/4" auxiliary fence, use 1/4"

 

round head screws wood screws (3/4" long). Drill
