0.087" (2.2 mm) THICK RIVING KNIFE. ONLY USE FOR 10" (254 mm) Ø BLADE WITH 0.094" (2.4 mm) MIN. KERF WIDTH AND 0.067" (1.75 mm) MAX. BODY THICKNESS.

FIG. 27

All DEWALT blade body thickness and kerf widths are provided at www.dewalt.com.

If a different blade is used and the body thickness

FIG. 28

and kerf width dimensions are not provided, use the

 

following procedure to determine the correct riving

 

knife thickness:

 

1.Measure the body thickness of the blade.

2.Make a shallow cut in scrap material and measure the kerf width.

3.Select the riving knife (Fig. 28).

4.Slide the riving knife through the shallow cut

made in step 2 to confirm the correct riving knife has been selected. The riving knife should not bind or drag through the cut (Fig. 28).

IMPORTANT: If any dragging or binding of the material is encountered as it reaches the riving knife, turn unit off and disconnect machine from power source. Repeat steps 1–4 to make the proper riving knife selection before attempting another cut.

Kickback

Kickback is a dangerous condition! It is caused by the workpiece binding against the blade. The result is that the workpiece can move rapidly in a direction opposite to the feed direction. During kickback, the workpiece could be thrown back at the operator. It can also drag the operator’s hand back into the blade if the operator’s hand is at the rear of the blade. If kickback occurs, turn the saw OFF and verify the proper functioning of the riving knife, anti- kickback assembly and blade guard assembly before resuming work.

WARNING: See Additional Safety Rules for Table Saws and follow all warnings provided regarding KICKBACK.

OPERATION

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 using the saw, verify the following each and every time:

•ALWAYS wear proper eye, hearing and respiratory equipment.

•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.

WARNING: To reduce the risk of serious personal injury, have push stick ready to use before starting cut.

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 this 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 DEWALT factory service center, a DEWALT authorized service center or other qualified service personnel if the problem cannot 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. Regardless of material, man made or natural wood, the distinction between ripping and crosscutting is as follows: Ripping is cutting to a different width (usually with the grain) and crosscutting describes cutting material across the shorter dimension (usually against the grain).

WARNING: When ripping, always use the fence to provide a guide for the material and blade guard assembly to protect against a kickback situation.

WARNING: Never perform any cutting operation free hand. Never perform plunge cutting. CAUTION: When crosscutting, always use the miter gauge.
