• Blade is tight.
• Bevel angle and height lock knobs are tight.
• If ripping, ensure fence lock lever is tight and fence is
parallel to the blade.
• If crosscutting, miter gauge knob is tight.
• The blade guard assembly is properly attached and the
anti-kickback assembly is functioning.
• ALWAYS inspect the blade guard assembly and riving
knife for proper alignment, operation and clearance with
saw blade.
• ALWAYS make sure both guards are in the down
position in contact with the table before operating.
Failure to adhere to these common safety rules can greatly
increase the likelihood of injury.
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.
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 operation
alignment and clearance with saw blade. Personal injury
may result.
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, a D
WALT authorized service center or other
E
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.
Guard Operating Feature (Fig. 31)
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. The guard(s) will lock in place when in the raised
position.
2. This feature increases visability when measuring the
blade to fence distance.
3. Push down on guard(s) and they will release to the
operating position.
ALWAYS make sure both guards are in the down
position in contact with the table before operating.

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.
WARNING: Keep hands clear of the blade
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 rip auxiliary fence 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. 32
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.
OPERATING
Both hands can be used in starting the cut. When there
POSITION
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

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
(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.
