OPERATION
TO MAKE NON-SLIDING CUTS
WARNING:
Securely tighten the slide lock knob when making
any non-sliding cuts. Failure to tighten the knob
could result in the saw head moving during the
cutting operation.
TO MITER CUT/CROSS CUT
See Figures 34 - 35.
A cross cut is made by cutting across the grain of the
workpiece. A straight cross cut is made with the miter table
°
set at the 0 position. Miter cross cuts are made with the
miter table set at some angle other than 0
 Make sure the slide lock knob is tightened securely.
 Raise saw arm to its full height.
To move the miter table to any of the indexed miter stops
(0°, 15°, 22.5°, 31.6°, 45°, 60° and 67.5° left or right):
 Lift the miter lock lever and press the miter detent bypass
button halfway. Release the detent bypass button. The
miter table will click into place when it reaches an indexed
stop.
 Push the miter lock lever down to lock the miter table.
To move the miter table to any desired position on the
miter scale:
 Lift the miter lock lever, then press the miter detent bypass
in all the way. The miter table will move freely left or right.
 Push the miter lock lever down to lock the miter table.
 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 cutting line on the workpiece with the edge of saw
blade.
 Turn the LED switch on to project the blade shadow onto
the workpiece.
 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.
 Grasp the saw handle firmly. Turn the switch on and 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 workpiece
and removing the workpiece from the miter table.
