DeWalt DWE7491 Original Instructions Manual page 45

Bench Mounting (fi g. 1)
CAUTION: To reduce the risk of
personal injury, make sure table saw
is firmly mounted to a stable surface
before use.
CAUTION: Ensure that the surface
is stable enough that large pieces of
material will not cause it to tip over
during use.
The table saw must be mounted firmly. Four holes (i)
are provided in the tool's base for mounting. We
strongly recommend that these holes be used to
anchor the table saw to your workbench or other
stationary rigid frame.
1. Center the saw on a square piece of
12.7 mm (1/2") plywood.
2. Mark the positions of the two rear mounting
holes (spaced 220 mm (8-5/8") apart) in the
frame of the saw with a pencil. Then measure
forward 498.5 mm (19-5/8") the two front holes.
3. Remove the saw and drill 9 mm (11/32") holes
in the places you have just marked.
4. Position the saw over the four holes you drilled
in the plywood and insert four 8 mm (5/16")
machine screws FROM THE BOTTOM. Install
washers and 8 mm (5/16") nuts on the top.
Tighten securely.
5. In order to prevent the screw heads from
marring the surface to which you clamp the
saw, attach two strips of scrap wood to the
bottom of the plywood base. These strips can
be attached with wood screws installed from
the top side as long as they don't protrude
through the bottom of the strip.
6. Use a "C" clamp to secure the plywood base to
your workbench whenever you use the saw.
ADJUSTMENTS
Blade Adjustment (fi g. 7)
BLADE ALIGNMENT (PARALLEL TO MITER SLOT)
WARNING: Cut Hazard. Check the
blade at 0˚ and 45˚ to make sure blade
does not hit the throat plate, causing
personal injury.
If the blade appears to be out of alignment with the
mitre slot on the table top, it will require calibration
for alignment. To realign the blade and mitre slot,
use the following procedure:
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing set-
ups or when making repairs. An
accidental start-up can cause injury.
1. Using a 6 mm hex wrench, loosen rear pivot
bracket fasteners (ff), located on the underside
of the table, just enough to allow the bracket to
move side-to-side.
2. Adjust the bracket until the blade is parallel to
the mitre gauge slot.
3. Tighten the rear pivot bracket fasteners to
110–120 in-lbs (12.5–13.6 Nm).
BLADE HEIGHT ADJUSTMENT (FIG. 1)
The blade can be raised and lowered by turning the
blade height adjustment wheel (f).
Make sure the top three teeth of the blade are just
breaking through the upper surface of the workpiece
when sawing. This will ensure that the maximum
number of teeth are removing material at any given
time, thus giving optimum performance.
Aligning Guard Assembly/Splitter to
Blade (fi g. 8)
1. Remove the throat plate. Refer to Remove
Throat Plate.
2. Raise the blade to full depth of cut and 0° bevel
angle.
3. Locate the three small set screws (ll) adjacent
to the guard assembly lock knob (mm).
These screws will be used to adjust the guard
assembly position.
5. Lay a straight edge on the table against two
blade tips. The splitter (m) should not touch the
straight edge. If needed, loosen the two larger
lock screws (nn).
6. Adjust the small set screws (ll) to move the
splitter according to the position noted in step
5. Lay the straight edge on the opposite side of
the blade and repeat adjustments as needed.
7. Lightly tighten the two larger lock screws (nn).
8. Place a square flat against the splitter to the
verify splitter is vertical and in-line with the
blade.
9. If needed, use the set screws to bring the
splitter vertical with the square.
10. Repeat steps 5 and 6 to verify position of
splitter.
11. Fully tighten the two larger lock screws (nn).
