OPERATION
WARNING:
Never make a cut by pulling the saw toward you
as the blade can climb on top of the workpiece
and come toward you. Failure to heed this warning
could result in serious personal injury.
TO SLIDE CUT
See Figures 32 - 33.
The sliding feature will cut workpieces 14 in. wide x
4-1/2 in. thick and 16 in. wide by 1-1/2 in. thick.
With the saw off, pull the saw arm forward. Turn the saw on
(let blade reach maximum speed), then push the blade down
on top of the workpiece then back toward the rear of the saw
to make a cut. Cuts are made by: (1) pushing the saw blade
away from you and toward the bevel scale at the back of the
saw, stopping when the full rear position has been reached
after each cut. When the saw is running (turned on), NEVER
pull the saw blade toward you or toward the front of the saw.
 Raise saw arm to its full height.
 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 Figures 50 and 51.
 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 44.
 Align the cutting line on the workpiece with the edge of
saw blade.
 Turn the LED switch on to project the blade shadow onto
the workpiece.
 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 or a C-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.
 Turn the saw on and allow several seconds for the blade
to reach maximum speed.
SLIDE SAW ARM FORWARD, THEN
 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.
