How To Ensure Proper Cutting Technique And Alignment?

Learn how to correct the issue of your Makita circular saw not cutting straight by ensuring proper cutting technique and alignment. Follow these guidelines to improve your cutting accuracy and achieve professional results.

Use A Straight Edge Or Guide

• Aligning the circular saw properly is crucial to ensure straight cuts. Using a straight edge or guide can help maintain the desired cutting line. Here’s how you can ensure proper alignment:
• Position the straight edge along the cutting line, making sure it is firmly secured. This can be done by clamping it down or using screws.
• Check if the straight edge is perfectly straight by using a level. Any discrepancies can lead to inaccurate cuts.
• Align the circular saw’s base plate along the straight edge or guide, using the saw’s guide notches or alignment marks.
• Make sure the saw’s blade is parallel to the straight edge or guide before making the cut.
• Maintain a firm grip on the circular saw, keeping it steady and in line with the straight edge or guide throughout the cutting process.

Apply Even Pressure And Let The Saw Do The Work

Applying even pressure while cutting is essential to prevent the circular saw from deviating from the desired cutting line. Follow these tips for proper cutting technique:

Hold the circular saw firmly with both hands. Position one hand on the main handle and the other on the auxiliary handle for better control.

Apply even, steady pressure on the saw as you guide it along the cutting line. Avoid pushing or pulling too hard, as this can lead to uneven cuts.

Let the saw’s motor and blade do the work. Avoid forcing the saw through the material, as it can cause the blade to bind or kick back.

Maintain a consistent cutting speed throughout the entire cut. Rushing or hesitating can result in inaccuracies.

Maintain A Steady And Straight Cutting Line

• Consistently maintaining a straight cutting line is key to achieving accurate cuts with a circular saw. Follow these tips to ensure a steady path:
• Focus on a fixed point on the cutting line, rather than directly on the saw’s blade. This helps prevent deviations and improves accuracy.
• Use your peripheral vision to monitor the alignment of the saw’s base plate with the cutting line. Make small adjustments if necessary to stay on track.
• Avoid unnecessary movements or jerks while cutting. Keep your body and arms steady, allowing the saw to smoothly move along the intended path.
• Use the appropriate cutting technique based on the material being cut. For example, for plywood or other thin materials, score the surface before making a complete cut.

Let The Blade Cool Down Between Cuts

• Overheating of the circular saw’s blade can affect its cutting performance and lead to inaccurate cuts. Follow these steps to ensure the blade remains in optimal condition:
• Allow the blade to cool down between cuts, especially when working on dense or thick materials. This helps prevent overheating, which can cause the blade to warp or dull prematurely.
• While the blade cools, take the time to clear away any debris or sawdust that may have accumulated on the cutting line or around the blade.
• If you notice the blade getting excessively hot during cutting, pause and let it cool down before continuing. This can help prolong the blade’s lifespan and maintain cutting accuracy.

Properly Store And Maintain Your Circular Saw

• Proper storage and maintenance of your circular saw are essential for optimal cutting performance. Here are some tips to keep your saw in excellent condition:
• Store the circular saw in a clean and dry environment, preferably in a protective case or designated storage area. This helps prevent damage from dust, moisture, or accidental bumps.
• Regularly clean the saw’s base plate, blade guard, and other components to remove debris or sawdust buildup. This promotes smoother cutting and optimal operation.
• Check and tighten any loose screws, bolts, or knobs on the saw to ensure stability and safety during use.
• Maintain the circular saw’s blade by sharpening or replacing it as needed. A dull or damaged blade can cause the saw to veer off course and produce uneven cuts.
• Follow the manufacturer’s guidelines for lubricating the saw’s moving parts, such as the pivot point or depth adjustment mechanism. Proper lubrication helps maintain smooth operation and extends the saw’s lifespan.

By following these techniques and properly maintaining your circular saw, you can ensure straight and accurate cuts, making your projects a breeze.
