DeWalt DWE7491 Instruction Manual page 13


WARNING: Before connecting to power source or operating the saw, always inspect the
riving knife for proper alignment and clearance with saw blade. Check alignment after each
change of bevel angle.
Non-Through-Crosscutting

WARNING: NEVER use rip fence in combination with miter gauge.

WARNING: To reduce the risk of injury, NEVER use the fence as a guide or length stop
when crosscutting.

WARNING: When using a block as a cut-off gauge, the block must be at least 3/4" (19 mm)
thick and is very important that the rear end of the block be positioned so the workpiece
is clear of the block before it enters the blade to prevent contact with blade resulting in a
thrown workpiece and possibly injury.
1. Remove the rip fence and place the miter gauge in the desired slot.
2. Adjust the blade height to the desired cut depth.
3. Hold the workpiece firmly against the miter gauge
the desired cut location. Keep the workpiece an inch or so in front of the blade. KEEP BOTH
HANDS AWAY FROM THE BLADE AND THE PATH OF THE BLADE.
4. Start the saw motor and allow the blade to come up to speed.
5. While using both hands to keep the workpiece against the face of the miter gauge, and
holding the workpiece flat against the table, slowly push the workpiece through the blade.
6. Never try to pull the workpiece with the blade turning. Turn the switch off, allow the blade to
stop, and carefully slide the workpiece out.
Non-Through-Bevel Crosscutting
This operation is the same as crosscutting except that the bevel angle is set to an angle other
than 0°.

WARNING: Before connecting connecting to power source or operating the saw, always
inspect the riving knife for proper alignment and clearance with saw blade. Check alignment
after each change of bevel angle.
Non-Through-Mitering (Fig. KK)
This operation is the same as crosscutting except the miter gauge is locked at an angle other than
0°. Hold the workpiece FIRMLY against the miter gauge
the blade (to prevent the workpiece from moving).
non-Through-Miter gauge Operation
To set your miter gauge:
1. Loosen the miter gauge lock knob 59 .
2. Move the miter gauge to the desired angle.
3. Tighten the miter gauge lock knob.
Fig. KK
non-Through-Compound Mitering
This is a combination of non-through-bevel crosscutting and non-through-mitering. Follow the
instructions for both non-through-bevel crosscutting and non-through-mitering.
Dado Cutting

CAUTION: Do not attempt to stack dado blades thicker than 13/16" (20 mm). Do not use
dado blades larger than 8" (200 mm) diameter.
Since dado cuts are non-through cuts, the cuts must be performed with the blade
guard assembly removed. Since the dado blade is smaller diameter and thicker than the standard
blade, the non-through cutting riving knife also cannot be used. To remove the blade guard
assembly or non-through cut riving knife, pull riving knife/blade guard release lever and pull up
on the guard or riving knife to remove.
Use EXTREME care when using the dado without the blade guard assembly and riving knife.
When using the dado, the special dado insert (also sold as an accessory) must be used.
Anytime a cut is required that is considerably wider than the saw kerf, a dado is used. A
dado cut is commonly used to add support and line up a shelf for a cabinet, bookcase or
some such project. If a deep cut is required, use several successive passes rather than
with the path of the blade in line with
10
10 and feed the workpiece slowly into
10
59
attempting to make it with one pass. Maximum dado width on this saw is 13/16" (20 mm).
DO NOT USE WIDER COMBINATIONS.

CAUTION: Always check dado blade clearance before plugging in the saw.
Be sure to place the blade guard assembly and standard throat plate back in position
and check adjustments when the dado cuts are complete. Reinstall blade guard
assembly, anti-kickback assembly and riving knife.
Dust Collection (Fig. A, LL)
This table saw is equipped with guard dust collection port
best results, connect a vacuum to the port at the rear of the saw and on the guard using a Y
connector. The Y connector is available as an accessory at additional cost. Refer to Accessories.
NOTICE: Care should be taken to position hoses to not interfere with cutting operation.
After extended use, the saw's dust collection system may become clogged. To clear the dust
collection system:
1. Unplug the saw.
2. Turn the saw on its side, so the bottom, open part of the unit is accessible.
3. Open the dust access door 50 shown in Figure LL by removing the screws and pressing the
the side clips 51 toward each other. Clean out the excess dust, and re-secure by pushing the
side clips completely into place and loose the screw.
Fig. LL
Motor Overload and Power Loss Reset Switch
If power is interrupted by a circuit breaker trip, or power is lost, the saw contains a power loss
reset switch feature that will automatically reset to OFF position.
Circuit breaker overload is often the result of a dull blade. Change your blade on a regular basis to
avoid tripping your breaker. Disconnect the saw from power source and check your blade before
re-setting the circuit breaker and continuing to saw.
Lubrication (Fig. MM)
1. All motor bearings are permanently lubricated at the factory and no additional lubrication
is needed.
2. The height adjustment screw may require periodic cleaning and lubrication to ensure thread
area clear. If you have difficulty raising or lowering the blade:
a. Unplug the saw.
b. Turn the saw on its side, so the bottom, open part of the unit is accessible.
c. Clean and lubricate the height adjustment screw threads
with general purpose grease. Refer to Figure MM.

STORAGE (FIG. NN–SS)
1. Attach push stick 22 to fence.
2. Remove blade guard assembly 11 . Refer to Remove Blade Guard Assembly. Slide blade
guard assembly into holder as shown, then turn lock 1/4 turn to lock in place.
3. Depress the stem on the anti-kickback assembly
riving knife slot.
