Cutting

Support the work so that the waste will be on your right. Place the wider portion of the saw shoe on that part of the work piece which is solidly supported, not on the section that will fall off when the cut is made. As examples, Figure 12 illustrates the RIGHT way to cut off the end of a board, and Figure 13 the WRONG way. Always clamp work. Don’t try to hold short pieces by hand! Remember to support cantilevered and overhanging material. Use caution when sawing material from below.

Be sure that the saw is up to full speed before blade contacts material to be cut. Starting the saw with blade against material to be cut or pushed forward into kerf can result in kickback.

Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and toughness can vary even in the same piece of material, and knotty or damp sections can put a heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep it working without much decrease in speed.

Kickback

When the saw blade becomes pinched or twisted in the cut, kickback can occur. The saw is thrust rapidly back toward the operator. When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit backward. When the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Kickback is more likely to occur when any of the following conditions exist.

1.IMPROPER WORKPIECE SUPPORT

A.Sagging or improper lifting of the cut off piece can cause pinching of the blade and lead to kickback (Fig. 11).

B. Cutting through material supported at the outer ends only can cause kickback. As the material weakens it sags, closing down the kerf and pinching the blade.

C. Cutting off a cantilevered or overhanging piece of material from the bottom up in a vertical direction can cause kickback. The falling cut off piece can pinch the blade.

D. Cutting off long narrow strips (as in ripping) can cause kickback. The cut off strip can sag or twist closing the kerf and pinching the blade.

E. Snagging the lower guard on a surface below the material being cut momentarily reduces operator control. The saw can lift partially out of the cut increasing the chance of blade twist.

2.IMPROPER DEPTH OF CUT SETTING ON SAW

To make the most efficient cut, the blade should protrude only far enough to expose 1/2 of a tooth as shown in figure 5. This allows the shoe to support the blade and minimizes twisting and pinching in the material. See the section titled Cutting Depth Adjustment.

3.BLADE TWISTING (MISALIGNMENT IN CUT)

A.Pushing harder to cut through a knot, a nail, or a hard grain area can cause the blade to twist.

B.Trying to turn the saw in the cut (trying to get back on the marked line) can cause blade twist.

C.Over-reaching or operating the saw with poor body control (out of balance), can result in twisting the blade.

D.Changing hand grip or body position while cutting can result in blade twist.

E.Backing up the saw to clear blade can lead to twist if it is not done carefully.

4.MATERIALS THAT REQUIRE EXTRA ATTENTION

A.Wet lumber

DW369, DW367 specifications

The DeWalt DW367 and DW369 are two powerful tools in the extensive lineup of DeWalt’s woodworking and construction equipment. Designed with durability and performance in mind, these models deliver impressive features and advanced technologies to cater to both professional contractors and DIY enthusiasts.

The DeWalt DW367 is a lightweight, cordless saw designed for versatility and ease of use. One of its primary features is its high-performance 18V battery, which offers extended run time and rapid charging capabilities. This allows users to work longer without the interruption of frequent battery changes. The DW367 is equipped with a powerful motor that generates sufficient speed and torque, enabling it to cut through various materials, including wood, metal, and composites, with precision.

One of the standout technologies integrated into the DW367 is its ergonomic design. The saw comes with a comfortable grip that reduces fatigue during prolonged use, making it ideal for extensive projects. Additionally, the built-in LED light illuminates the cutting area, ensuring accuracy and visibility even in low-light conditions. The tool also features a tool-free blade change system, allowing users to switch blades quickly and efficiently without the need for additional tools.

On the other hand, the DeWalt DW369 is engineered for more demanding tasks. This model boasts advanced electronics that provide overload protection, preventing the motor from overheating and extending the tool's lifespan. It also offers a higher cutting capacity, making it suitable for thicker materials and more intricate cuts.

A notable characteristic of the DW369 is its adjustable bevel and depth cut features. These allow users to make precise bevel cuts and adjust the depth of the cut according to the material being worked with. This flexibility is essential for professionals who require accuracy and versatility in their work.

Both models leverage DeWalt's commitment to safety, incorporating an electric brake that instantly stops the blade upon disengaging the switch, minimizing the risk of accidents. Furthermore, each tool comes with a robust housing that enhances durability, ensuring they can withstand the rigors of job site conditions.

In summary, the DeWalt DW367 and DW369 are exemplary tools that combine power, versatility, and safety. With their advanced features and reliable technologies, both models can meet the diverse needs of users, making them invaluable additions to any workshop or job site. Their focus on user comfort and operational efficiency speaks to DeWalt's dedication to quality and innovation in the power tools industry.
