DeWalt DWE7499 Guide D'utilisation page 13

WARNING: Use a push stick to feed the workpiece if there is 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 is 2" (51 mm) or narrower 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.
FIG. 33 A
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 33.
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 or slightly lower than the saw table.
CAUTION: Never push or hold onto the free or cut-off side of the workpiece if it is between
the blade and the fence.
Ripping Small Pieces (Fig. 34)
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 (V) 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.

Narrow Rip Auxiliary Fence (Fig. 35, 36)
The narrow rip auxiliary fence should be used for a rip measuring 2" (51 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 (TT, see Push Block).
1. Follow the diagram in Fig. 35 to construct the narrow rip auxiliary fence (SS).
NOTE: The length should be cut to fit the length of the saw table top and sides (TT) 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 37.
3. Feed the workpiece through until the edge of the material reaches the front edge of the
saw table top.
4. Continue feeding the material using the push block (UU) until the cut is complete.
Push Block (Fig. 36, 37)
IMPORTANT: Only use the push block (UU) with the narrow rip auxiliary fence, refer to
Narrow Rip Auxiliary Fence. The push block should be used once the material being cut
reaches the saw table top.
1. Construct a push block using the diagram in Figure 36.
NOTE: Edges (V V) must be the same size.
IMPORTANT: The over hanging edge (V V, Fig. 36) MUST be square. An uneven lip could
cause the push block to slip or push the material away from the fence.
