English

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 half of a tooth as shown in Figure 5. This allows the foot plate 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.

4.MATERIALS THAT REQUIRE EXTRA ATTENTION

A.Wet lumber

B.Green lumber (material freshly cut or not kiln dried)

C.Pressure treated lumber (material treated with preservatives or anti-rot chemicals)

5.USE OF DULL OR DIRTY BLADES

Dull blades cause increased loading of the saw. To compensate, an operator will usually push harder which further loads the unit and promotes twisting of the blade in the kerf. Worn blades may also have insufficient body clearance which increases the chance of binding and increased loading.

6.LIFTING THE SAW WHEN MAKING BEVEL CUT

Bevel cuts require special operator attention to proper cutting techniques - especially guidance of the saw. Both blade angle to the foot plate and greater blade surface in the material increase the chance for binding and misalignment (twist) to occur.

7.RESTARTING A CUT WITH THE BLADE TEETH JAMMED AGAINST THE MATERIAL

The saw should be brought up to full operating speed before starting a cut or restarting a cut after the unit has been stopped with the blade in the kerf. Failure to do so can cause stalling and kickback.

Any other conditions which could result in pinching, binding, twisting, or misalignment of the blade could cause kickback. Refer to the sections on adjustments and operation for procedures and techniques that will minimize the occurrence of kickback.

DWS535 specifications

The DeWalt DWS535 is a powerful and versatile circular saw that is designed to meet the rigorous demands of professionals and DIY enthusiasts alike. Known for its solid construction and cutting-edge technology, the DWS535 showcases the brand's commitment to quality and innovation in woodworking tools.

One of the standout features of the DWS535 is its robust 15-amp motor, which delivers a remarkable no-load speed of 5,300 RPM. This ensures users can tackle a variety of cutting tasks with ease and confidence, whether working with lumber, engineered wood products, or other materials. The high-speed blade cuts through even the toughest materials quickly and efficiently, making it ideal for framing, decking, and general carpentry projects.

The DWS535 is equipped with a 7-1/4 inch carbide-tipped blade that enhances cutting accuracy and durability. The blade's design allows for smooth and clean cuts, reducing the need for post-processing. Additionally, the saw’s integrated electric brake stops the blade quickly after the trigger is released. This safety feature not only enhances user control but also minimizes the risk of accidental injuries, making it a safer choice for operators.

Comfort and usability are also central to the design of the DWS535. It features a lightweight, well-balanced construction that allows for easy maneuverability. Furthermore, the ergonomic handle is designed to reduce fatigue during extended use, providing better grip and control. The saw’s bevel capacity of 0° to 45° contributes to its versatility, enabling users to achieve angled cuts with precision.

Incorporating advanced technologies, the DWS535 features a built-in rafter hook that provides convenient storage and accessibility. Additionally, the saw is designed with a durable protective blade guard that enhances safety while allowing users to easily visualize their cutting line. The tool’s dust port is another thoughtful addition, helping to keep the workspace clean and free from debris, ultimately improving visibility for better accuracy.

Overall, the DeWalt DWS535 stands out in a crowded market of circular saws with its powerful performance, safety features, and user-friendly design. Whether you’re a seasoned professional or a weekend warrior, this tool is engineered to deliver efficiency, accuracy, and safety on every job site. With its remarkable combination of features, the DWS535 proves to be a wise investment for anyone serious about woodworking or construction.
