OPERATION
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 Figures 51 and 52.
 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 39.
 Turn the LED switch on.
 Lower the blade and align the cutting line on the
workpiece with the edge of saw blade or the blade
shadow.
 Loosen the slide lock knob by turning the knob counter-
clockwise.
 Grasp the stock firmly with one hand and secure it against
the fence. Use the work clamp, C-clamp, or other suitable
clamp to secure the workpiece when possible.
 Before turning on the saw, perform a dry run of the cut-
ting operation to make sure that no problems will occur
when the cut is made.
 With the saw off, grasp the saw handle firmly then pull
the saw forward until the blade arbor (center of the saw
blade) is over the front of the workpiece or until the saw
is fully extended.
 Grasp the saw handle firmly. Depress the trigger lockout
lever and squeeze the switch trigger. Allow several sec-
onds for the blade to reach maximum speed.
 Slowly lower the blade into and through the front edge
of the workpiece.
 Push the saw handle away from you and toward the bevel
scale at the back of the saw.
 Release the switch trigger and allow the saw blade to
stop rotating before raising the blade out of workpiece
and removing the workpiece from miter table.
MAKING AN AUXILIARY FENCE
See Figure 43.
Depending on the size and position of the workpiece, certain
unusual cuts may benefit from the additional support that
can be provided by an auxiliary fence. The holes provided
in the sliding miter fence are used to secure an auxiliary
fence in place.
NOTE: The auxiliary fence can only be used when the bevel
is set at 0°. When making a bevel cut, the auxiliary fence
MUST be removed.
NOTE: It may be necessary to adjust the sliding miter fence
to ensure proper clearance prior to installing auxiliary fence.
To attach the auxiliary fence to the saw:
 Make sure the fence lock knob is tightened securely.
 Place one 10 in. long piece of wood against the miter
fence and aligned with the left edge of the miter table.
 Clamp the wood tightly against the fence and drive wood
screws from the back of the fence through the two holes
and into the auxiliary fence. If necessary, drill a pilot hole
into wood first to prevent splitting. Remove clamp when
finished.
NOTE: Make sure the screws you use to attach the auxil-
iary fence do not pass through the front face of the fence
and the length of the screws will not put them in the path
of the blade at any angle.
 Make full left miter cut through the auxiliary fence.
NOTE: Check for interference between the auxiliary fence
and the lower blade guard. Correct any interference be-
fore proceeding.
 Repeat steps with second board by aligning with right side
of miter table and making a full right miter cut through the
auxiliary fence.
