Causes and Operator Prevention of Kickback

English

•Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.

•Never use damaged or incorrect blade washers or bolts. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

•Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.

•Do not operate this tool for long periods of time. Vibration caused by the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.

CAUSES AND OPERATOR PREVENTION OF KICKBACK

•Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece 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 rapidly back toward the operator.

•If 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 operator.

•Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

•Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken.

•When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.

•When restarting a saw in the workpiece, center the saw blade in the kerf and check that the saw teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.

•Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Support must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

•Do not use dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding, and kickback.

•Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and KICKBACK.

•Use extra caution when making a “Pocket Cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

•lead from lead-based paints,

•crystalline silica from bricks and cement and other masonry products, and

•arsenic and chromium from chemically-treated lumber (CCA).

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.
