How To Use A Circular Saw?
Circular saw is a crucial part of all carpenters and craftsmen’s toolkit. The circular saw makes it easy to get clean and precise cuts via a large variety of different materials. It is as easy setting a saw blade to an appropriate angle and depth, lining up with the material, & guiding it easily over the already drawn measurement lines. Also, before you start sawing, it is quite essential to get familiarized with different design features that you are using, & be sure that you wear gloves & eye protection for keeping yourself secure whilst you work.
Part 1: Adjusting the Saw & Preparing for Work Materials
1. You should take enough time to get familiarized with a circular saw that you are using. There’re different styles and brands of the circular saws.
- A circular saw is to modify composite materials, sheet metal, and rolled steel stock.
2. Must wear gloves & eye protection for keeping yourself secure whilst you work.
- In case you’ve sensitive airways then strap on the respirator or dust mask for avoiding inhaling sawdust.
3. Measure & mark the material where you will be making cuts. Use some ruler or straight edge & the carpenter’s pen, pencil, or marker for drawing the straight line where you want to saw the material.
- For the precision, follow: “measure twice, cut once.”
4. Put required material between 2 sawhorses or on the saw table. Make sure the material that you are cutting is well-supported & free of any obstructions. Hence, this way, you will not need to worry regarding blade diggings into the work surface because this passes through the material.
- You could find many sawhorses in different sizes for 30 to 50 dollars at some local hardware shop or the home improvement center.
5. You need to use a central lever for setting your blade to the required cutting depth. The, pull your shoe lever between 2 handles in order to disengage your baseplate& allow this to freely move. From there, put your baseplate against the material & lower or raise your blade until this stops at.
- Just set the blade 1⁄8 in (.32 cm) -1⁄4 in (.64 cm) just below the material. Also, setting this much deeper wouldn’t only force this to work quite hard, but also will leave teeth exposed, that could be harmful.
- Set your saw blade to correct depth so it would make sure clean cuts & decrease friction that might wear down teeth & leave some imperfections in your material which is not your ultimate target.
6. You have to adjust a pivoting scale in order to angle your blade for the cuts. Twist a small knob on the rear end of your saw counterclockwise for unlocking the scale which sits well around your blade. Also, slide your scale to 1 of the angles that are indicated on its frame, or can stop this at any time for making custom cuts. When you are well-satisfied with your angle, turn it clockwise for locking your scale in place.
- You need to make sure that locking knob is safe before activating your saw. Else, the scale might move as your blade makes some contact with the material.
- Altering an angle of your blade would let you make the leveled cuts along with squared edges and get the exact contouring on the oddly-shaped pieces.
Part 2: Making Neat and Precise Cuts
1. You need to position a line on your baseplate that is labeled with "zero" over the cut line. And, on the rear edge of your baseplate, you will see some small notch along with one bold line. So, the line on the left side of the notch would be labeled as "zero." This corresponds to blade’s position when it is set to ninety degrees, & must be used when you are making some normal cuts.
- A line that is labeled as "45" on the right side of a notch is also for making the cuts at the precise 450 angle.
2. You need to activate your saw blade through pulling your trigger on the rear handle. In some models, there’s another safety trigger that is near the saw which you will have to flip for your saw in order to start up while you will pull your handle trigger. When you engage your trigger, its blade would start spinning. You have to wait until this gets up almost to full speed in order to begin the cutting.
-In case you are right-handed then it would probably be quite comfortable for gripping the front handle with the right hand & place the left hand on the rear handle in order to give more stability when you work. In case you are left-handed then just reverse the orientation.
-You need to hold off pulling your trigger until double-check the measurements and make sure that your baseplate is aligned properly & are actually prepared to start cutting.
3. Now, push your saw smoothly and slowly along the material. Also, use your hands for maneuvering the circular saw just straight down a cut line. You must make sure that the right-side of your baseplate notch actually stays aligned along with the cut line. You should avoid jerking or forcing the circular saw along, keep this moving at a natural and easy speed as saw blade just passes the material.
- In most of the models, blade guard would retract automatically when you move your saw forward & lower while you lift this off. You could also pull this back manually in order to keep this while making an irregular or angled cuts.
- Trying to move your saw quickly could raise the chances of mistakes and cause your blade to be jammed with the debris.
4. Release your trigger in order to stop saw blade while each cut. When you have finished your cut, let go of your trigger & wait for your blade for coming to some complete stop.
- Do not put your fingers on your trigger unless you are preparing for making a cut. In case you aren’t careful then you might activate your saw accidentally.
