How to Safely and Effectively Use a Circular Saw?

Circular saws can even cut virtually any material if you have the right type of blade and know the precise technique; it is why it is one of the most used tools for carpentry work. In spite of being one of the most used electric tools, it is always good to review some basic tips that allow us to achieve the expected results.

Supervision of the Tool and the Workspace

These are a few simple steps that every operator should consider before starting to work with a circular saw:

Check the locking switch.

The locking switch, or safety switch, is the device that prevents the saw from being accidentally actuated. It is essential to verify that the tool is locked before starting work with it, and even before connecting it to the mains. Re-lock the saw each time you finish using it.

Check the general condition of the circular saw.

Make sure that the cutting blade is in optimum condition, and no traces of rust, sharpness, cracks or deviations. Thoroughly check the protective casing and controls.

Check the state of your workplace

It is vital that it is in perfect order, and make sure to avoid the presence of unnecessary objects as well as clearing all the space required to make cuts. It is also advisable to eliminate all traces of sawdust or other debris before starting work and even during labor as it will allow better visualization of the results. Always wear thick gloves and goggles when cutting.

Preparation of the Cut

One of the circular saw’s characteristics is it allows the user to change the cutting discs. There is an enormous variety. Each type is designed to work with a particular type of material and perform a specific, precise kind of cutting.

For almost any type of wood, you can use large toothed discs, if the direction of cutting is parallel to the grain or threads of the wood. On the other hand, fine-toothed discs are designed to make cuts that are more precise and require more significant force, such as hardwoods, conglomerates, plywood, etc.

Circular saw in motion

Some models incorporate carbide or diamond tips which makes them much more resistant and durable and allows working with materials as hard as concrete. Finally, outstanding toothed discs allow precision work to be carried out and cuts to be made perpendicular to the grain or thread of the wood.

It is crucial to choose the right cutting blade for each type of job because if the material offers too much strength or too little. The saw could get out of control and ruin the material or cause an accident.

Always disconnect the saw from the power supply before changing the blade, adjusting the depth or inclination, or making any adjustments.

Saws allow you to adjust the depth or height of the cut. To measure it, you can place the piece you want to cut next to the saw and adjust it so that the saw does not exceed the edge of the material by more than 4 mm.

Before cutting, make sure that there are no knots, nails, or other obstacles in the wood that could interrupt cutting. Fix the wood to a stable surface and make sure that it is perfectly firm throughout the operation. When measuring and marking the guidelines always consider the width of the cut-off wheel.

Many manual saw models have built-in guides that can be adjusted to ensure a perfectly straight cut. In case your model does not have them, or the size of the guides is insufficient, you can always use a straight piece of wood or aluminum to serve as a reference.

If you need to make a cut perpendicular to the grain or threads of the wood, you can first mark the cutting line using a fork. Mark the line at least three times with the edge of the lashing before using the circular saw.

Cutting techniques:

  • Check that the power cable does not interfere with the direction of the cut.
  • Place the machine in position and lean over it.
  • Start the machine. The sound of the engine makes it easy to recognize when the engine has reached its maximum speed and maintains a constant speed.
  • check
    When holding the saw, be careful not to exert excessive pressure on it. Hold it firmly.
  • check
    When starting the cut, make a slow movement until the blade is inside the material. Then advance at a constant speed, guided by the sound of the saw to be cut which should be as regular as possible.
  • check
    If the sound of the saw becomes too low, it is a sign that the blade is encountering too much resistance. To avoid this, make a slower movement, or replace the blade with one with smaller teeth.
  • check
    Do not stop the saw until you have completed the work.

Safety First

Although they are tools that are used every day, never forget that saws are dangerous tools. Their misuse can cause everything from minor injuries to mutilations. These simple tips will help you to do a neat job, but above all, they will allow you to take care of your safety.
