DeWalt DWE7470 Instruction Manual page 13

WARNING: Ripping or crosscutting may cause saw to tip over while operating. Make sure
saw is securely mounted to a stable surface.
WARNING: Never use the fence and miter gauge together. This may cause a kickback
condition and injure the operator.
CAUTION: If your saw makes an unfamiliar noise or if it vibrates excessively, cease
operating immediately, turn unit off and disconnect from power source until the problem has
been located and corrected. Contact a D
service center or other qualified service personnel if the problem can not be found.
CAUTION: The proper throat plate must be in place at all times to reduce the risk of a
thrown workpiece and possible injury.
There are two basic types of cutting with table saws: ripping and crosscutting. Cutting
with the grain is ripping and cutting against the grain is crosscutting. With man made
materials, the distinction is made such that ripping is cutting to a different width and
crosscutting describes cutting material across the shorter dimension.
WARNING: When ripping, always use the fence to provide a guide for the material and
blade guard assembly against a kickback situation.
WARNING: Never perform any cutting operation free hand. Never perform plunge cutting.
CAUTION: When crosscutting, always use the miter gauge.
Ripping (Fig. 32)
WARNING: Never touch the "free end" of the workpiece or a "free piece" that is cut off, while
the power is ON and/or the saw blade is rotating. Piece may contact the blade resulting in a
thrown workpiece and possible injury.
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. Keep hands clear of the blade
and use a push stick to feed the workpiece if there is less than 6" (152 mm) between the fence
and the blade.
1. Lock the rip fence by pressing the rail lock lever down. Remove the miter gauge.
2. Raise the blade so it is about 1/8" (3.2 mm) higher than the top of the workpiece.
3. Hold the workpiece flat on the table and against the fence. Keep the workpiece about 1"
(25.4 mm) away from the blade.
CAUTION: 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 32.
4. Turn the saw on and allow the
blade to come up to speed. Both
hands can be used in starting the
cut. When there is 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.
5. 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.

6. Never try to pull the workpiece back with the blade turning. Turn the switch off, allow the
blade to stop, raise the anti-kickback teeth on each side of the riving knife if necessary and
slide the workpiece out.
7. 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 as the saw table.
CAUTION: Never push or hold onto the "free" or "cut off" side of the workpiece.
Ripping Small Pieces (Fig. 33)
It is unsafe to rip small pieces.
FIG. 33
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 (U) is
included with this saw,
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. See
Figure 33.
Narrow Rip Auxiliary Fence (Fig. 34–36)
The narrow rip auxiliary fence should be used for a rip measuring 2" (50.8 mm) or narrower.
This fence will allow the guard to remain on the saw when completing narrow ripping. This
fence will provide ample space for proper use of a push block (A12, see Push Block).
1. Follow the diagram in Figure 34 to construct the narrow rip auxiliary fence (A13, Fig. 36).
NOTE: A11 should be cut to fit the length of the saw table top and sides (A14) must be
parallel.

2. After the narrow rip auxiliary fence is constructed, slip it over the saw table top and place
it flush to the fence as shown in Figure 36.
