Step 2: measure

Next, grab the wood that you want to cut. Measure the line to be cut on the wood using a measurement tool and mark it with a pencil. Don’t forget to measure them more than twice to be assured about it.

Now the next step is to put the wood on the table. Place your wood securely against the fence. It will assist you in avoiding backlash and achieving a precise cut. Rotate the saw so that it is perfectly aligned with the mark. For a 45-degree cut, alter it to a 45-degree angle and lock properly.

Step 5: Make The Cut

Grab the board in one palm while using the other hand to carefully press the saw down into the wood. Cut the wood with extreme caution. It is not necessary to push the saw, rather the saw will do the work. Once you have finished cutting the board, Wait for the blade to fully stop spinning. Then, pull the blade away from the wood.
