 Place the workpiece flat on the miter table with one edge
securely against the fence. If the board is warped, place
the convex side against the fence. If the concave edge
of a board is placed against the fence, the board could
collapse on the blade at the end of the cut, jamming the
blade. See figure 31.
 When cutting long pieces of lumber or molding, support
the opposite end of the stock with a roller stand or with
a work surface level with the saw table. See Figure 29.
 Align the cutting line on the workpiece with the edge of
saw blade or laser line.
 Grasp the stock firmly with one hand and secure it against
the fence. Use the optional work clamp or a C-clamp to
secure the workpiece when possible. See Figure 28.
 Before turning on the saw, perform a dry run of the cutting
operation just to make sure that no problems will occur
when the cut is made.
 Grasp the saw handle firmly. Depress the switch lock
with thumb then squeeze the switch trigger. Allow several
seconds for the blade to reach maximum speed.
 Slowly lower the blade into and through the workpiece.
 Release the switch trigger and allow the saw blade to stop
rotating before raising the blade out of the workpiece.
Wait until the blade stops turning before removing the
workpiece from miter table.
TO SUPPORT LONG WORKPIECES
See Figure 29.
Long workpieces need extra supports. Supports should be
placed along the workpiece so it does not sag. The support
should let the workpiece lay flat on the base of the saw and
worktable during the cutting operation. Use the optional work
clamp or a C-clamp to secure the workpiece.
