Compound Mitering - DeWalt DWE7491 Instruction Manual

English
Fig. GG
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.

CAUTION: Never touch or hold onto the free or cut-off end of the workpiece.
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 the table saw to the power source or operating the saw,
always inspect the blade guard assembly and riving knife for proper alignment and
clearance with saw blade. Check alignment after each change of bevel angle.
Mitering (Fig. HH)

WARNING: Miter angles greater than 45˚ may force the blade guard assembly into the saw
blade causing damage to the blade guard assembly and personal injury. Before starting
the motor, test the operation by feeding the workpiece into the blade guard assembly. If
the blade guard assembly contacts the blade, place the workpiece under the blade guard
assembly, not touching the blade, before starting the motor.

CAUTION: Certain workpiece shapes, such as molding may not lift the blade guard assembly
properly. Feed the workpiece slowly to start the cut. If the blade guard assembly contacts the
blade, place the workpiece under the blade guard assembly, not touching the blade, before
starting the motor.
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).

Miter Gauge Operation
To set your miter gauge:
1. Loosen the miter gauge lock knob.
2. Move the miter gauge to the desired angle.
3. Tighten the miter gauge lock knob.

Compound Mitering

This is a combination of bevel crosscutting and mitering. Follow the instructions for both bevel
crosscutting and mitering.
Non-Through-Cutting (Grooving and Rabbeting)

WARNING: Remove the blade guard assembly
riving knife for non-through-cutting operations. Use featherboards for all non-through-
23
cutting operations where the blade guard assembly, anti-kickback assembly and riving kife
cannot be used.

11 and install the non-through-cutting
Instructions in the Ripping, Crosscutting, Bevel Crosscutting, Mitering, and Compound
Mitering sections are for cuts made through the full thickness of the material. The saw can also
perform non-through cuts to form grooves or rabbets in the material.
Non-Through-Ripping (Fig. II)

WARNING: A rip fence should ALWAYS be used for ripping operations to prevent loss of
control and personal injury. NEVER perform a ripping operation freehand. ALWAYS lock the
fence to the rail.

WARNING: When bevel ripping and whenever possible, place the fence on the side of the
blade so that the blade is tilted away from the fence and hands.

WARNING: Keep hands clear of the blade. With non-through-cutting the blade is not
always visible during the cut, so increased caution is necessary to ensure hands are clear of
the blade.

WARNING: Use a push stick to feed the workpiece if there are 2–6" (51–152 mm) between
the fence and the blade. Use a narrow ripping fence feature and push block to feed the
workpiece if there are 2" (51 mm) or narrower between the fence and the blade.
1. Remove the blade guard assembly 11
(Fig. G). Refer to Installing/Removing the Blade Guard Assembly and Riving Knife.
2. Lock the rip fence by pressing the rail lock lever down. Remove the miter gauge.
3. Raise the blade to the desired cut depth.
4. Hold the workpiece flat on the table and against the fence. Keep the workpiece about 1"
(25.4 mm) away from the blade.
Fig. II

WARNING: The workpiece must have a straight edge against the fence and must not be
warped, twisted or bowed. Keep both hands away from the blade and away from the path of
the blade. See proper hand position in Figure II.
5. Turn the saw on and allow the blade to come up to speed. Both hands can be used in starting
the cut. When there are approximately 12" (305 mm) left to be ripped, use only one hand,
with your thumb pushing the material, your index and second finger holding the material
down and your other fingers hooked over the fence. Always keep your thumb along side your
first two fingers and near the fence.
6. Keeping the workpiece against the table and fence, slowly feed the workpiece rearward all
the way through the saw blade. Continue pushing the workpiece until it is clear of the blade
guard assembly and it falls off the rear of the table. Do not overload the motor.
7. Never try to pull the workpiece back with the blade turning. Turn the switch off, allow the
blade to stop and slide the workpiece out.
8. When sawing a long piece of material or a panel, always use a work support. A sawhorse,
rollers, or out feed assembly provides adequate support for this purpose. The work support
must be at the same height or slightly lower than the saw table.
Non-Through-Ripping Small Pieces (Fig. A)
It is unsafe to rip small pieces. It is not safe to put your hands close to the blade. Instead, rip a
larger piece to obtain the desired piece. When a small width is to be ripped and the hand cannot
be safely put between the blade and the rip fence, use one or more push sticks. A pattern is
included at the end of this manual to make push sticks. A push stick
attached to the rip fence. Use the push stick(s) to hold the workpiece against the table and fence,
and push the workpiece fully past the blade.
Non-Through-Bevel Ripping (Fig. JJ)
This operation is the same as non-through-cut ripping except the bevel angle is set to an angle
other than zero degrees. For proper hand position, Refer to Figure JJ.
