OPERATION
TO BEVEL CUT
See Figures 40 - 41.
A bevel cut is made by cutting across the grain of the
workpiece with the blade angled to the workpiece. A straight
bevel cut is made with the miter table set at the zero degree
position and the blade set at an angle.
Bevel cuts may be made by angling the blade to the left or
right.
This saw has a three-position bevel lock lever.
 Pull the bevel lock lever all the way forward to free the
saw arm to select any setting on the bevel scale.
 When getting close to the desired bevel position, place
the bevel lock lever in the center position to easily find
one of the detents and select an indexed position on the
bevel scale.
NOTE: Indexed bevel positions are located at 0°, 15°,
22.5°, 33.9°, and 45° left or right.
 Push the bevel lock lever to the locked position to lock
the saw arm into place.
NOTE: It may be necessary to adjust or remove the sliding
miter fence to insure proper clearance prior to making the cut.
 Make sure the slide lock knob is tightened securely.
 Raise saw arm to its full height.
 Lift the miter lock lever and press the miter detent bypass
button. Set the miter table to zero.
 Push the miter lock lever down to lock the miter table.
 Place the bevel lock lever in the center position to select
one of the preset bevel settings or place the bevel lock
lever in the forward position to select any desired setting.
 Move the saw arm left or right to the desired bevel angle.
 Push the bevel lock lever to its locked position.
 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 51 - 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 44.
 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.
 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 saw handle firmly. Turn on the saw 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 the workpiece and
removing the workpiece from the miter table.
