Workpiece Support
Long pieces need extra supports. The supports should
be placed along the workpiece so the workpiece does not
sag and your hand holding the workpiece is positioned 4"
or more from the blade path. The support should let the
workpiece lay flat on the base and work table during the
cutting operation.
NOTE: When mounted on a large flat surface, the miter
saw table is 3 1/2" high. A finished 4x4 or a supported
2x4 on edge can be used as work support extension.
Auxiliary Fence
Certain unusual cuts may benefit from a fence face
extension due to the size and position of the workpiece.
Holes are provided in the fence to attach an auxiliary
fence. Get a straight piece of wood typically 1/2 inch thick
by 4-1/4 inches high by 23-1/2 or 28 inches long. To
attach auxiliary fence, place the piece of wood on the
miter saw fence. Mark the hole locations from the back-
side of the miter saw fence. Drill .200"-.250" holes, then
countersink the holes on front of wood to receive #10 flat
head screws. Attach the auxiliary fence securely and
make a full depth cut. This will create the blade slot.
Check for interference between the auxiliary fence and
lower blade guard. Correct any interference before pro-
ceeding. The auxiliary fence is used with the saw in the
0° bevel position. If a bevel cut is desired, the auxiliary
fence will have to be removed.
