Bevel Cuts - DeWalt DHS790 Manual De Instrucciones

For best results, use the DW7080 extension work support to extend the table width of your
saw, available from your dealer at extra cost. Support long workpieces using any convenient
means such as sawhorses or similar devices to keep the ends from dropping.
CROSSCUTS (FIG. 4, 21)
A crosscut is made by cutting wood across the
grain at any angle. A straight crosscut is made
with the miter arm at the zero degree position.
Set and lock the miter arm at zero, hold the
wood firmly on the table and against the fence.
With the rail lock knob (V) tightened, turn on the
saw by squeezing the trigger switch shown in
Figure 4.
When the saw comes up to speed (about 1
second) lower the arm smoothly and slowly to
cut through the wood. Let the blade come to a
full stop before raising arm.
When cutting anything larger than a 2 x 8 (51
x 203 mm [2 x 6 (51 x 152) at 45º miter]) use
an out-down-back motion with the rail lock
knob (V) loosened. Pull the saw out, toward
you, lower the saw head down toward the
workpiece, and slowly push the saw back to
complete the cut. Do not allow the saw to
contact the top of the workpiece while pulling
out. The saw may run toward you, possibly
causing personal injury or damage to the workpiece.
Cutting of multiple pieces is not recommended but can be done safely by ensuring that each
piece is held firmly against the table and fence.
NOTE: To provide greater crosscut capacity with reduced stroke, the blade on the saw
extends deeper into the table. As a result, a greater lifting force on the workpiece may be
experienced during the cut.
CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece
damage and personal injury, if your hands are required to be within 6" (152 mm) of the blade
during the cut.
NOTE: The rail lock knob (V) shown in Figure 4 must be loose to allow the saw to slide along
its rails.
Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often
45º for making corners, but can be set anywhere from zero to 50º left or 60° right. Make the
cut as described above.
When performing a miter cut on workpieces wider than a 2 x 6 that are shorter in length,
always place the longer side against the fence (Fig. 21).
To cut through an existing pencil line on a piece of wood, match the angle as close as
possible. Cut the wood a little too long and measure from the pencil line to the cut edge to
determine which direction to adjust the miter angle and recut. This will take some practice,
but it is a commonly used technique.

BEVEL CUTS

A bevel cut is a crosscut made with the saw blade leaning at an angle to the wood. In order
to set the bevel, loosen the bevel lock (V, Fig. 4), and move the saw to the left or right as
desired. (It is necessary to move the fence to allow clearance.) Once the desired bevel angle
has been set, tighten the bevel lock firmly. Refer to the Features and Controls section for
detailed instructions on the bevel system.
Bevel angles can be set from 49º right to 49º left and can be cut with the miter arm set
between 50º left or 60º right. At some extreme angles, the right or left side fence might have

to be removed. To remove the left or right fence, unscrew the fence adjustment knob several
turns and slide the fence out.
NOTE: Refer to Fence Adjustment in the Adjustments section for important information on
adjusting the fences for certain bevel cuts.
Cutting Picture Frames, Shadow Boxes And Other Four-
Sided Projects (Fig. 22, 23)
To best understand how to make the items listed here, we suggest that you try a few simple
projects using scrap wood until you develop a "feel" for your saw.
Your saw is the perfect tool for mitering corners like the one shown in Figure 22. Sketch A in
Figure 23 shows a joint made by using the bevel adjustment to bevel the edges of the two
boards at 45º each to produce a 90º corner. For this joint the miter arm was locked in the
zero position and the bevel adjustment was locked at 45º. The wood was positioned with the
broad flat side against the table and the narrow edge against the fence. The cut could also
be made by mitering right and left with the broad surface against the fence.

Cutting Trim Molding And Other Frames (Fig. 23)
Sketch B in Figure 23 shows a joint made by setting the miter arm at 45º to miter the two
boards to form a 90º corner. To make this type of joint, set the bevel adjustment to zero and
the miter arm to 45º. Once again, position the wood with the broad flat side on the table and
the narrow edge against the fence.
The two sketches in Figure 23 are for four-sided objects only.
As the number of sides changes, so do the miter and bevel angles. The chart below gives the
proper angles for a variety of shapes.

The chart assumes that all sides are of equal length. For a shape that is not shown in the
chart, use the following formula: 180º divided by the number of sides equals the miter (if the
material is cut vertically) or bevel angle (if the material is cut laying flat).
