How To Change Blade On Skilsaw Circular Saw?

If you’re like me, you probably don’t think about changing the blade on your Skilsaw circular saw until it’s too late and the old one is so dull that it’s barely cutting. In this blog post, I’m going to show you how to quickly and easily change the blade on your Skilsaw circular saw. So whether you’re a professional carpenter or just doing some DIY projects around the house, keeping a sharp blade on your Skilsaw will make each job go much more smoothly. Stay safe out there!

Steps How To Change Blade On Skilsaw Circular Saw:

Step 1: 

Unplug your Skilsaw from the wall and set it on a table or workbench. Then, flip the saw over to expose its underside. There should be a black lever next to the blade that’s used to release the current one in order to install another one in its place. While pushing this lever upwards, rotate the blade so that it unlocks.

Step 2: 

Once the current blade is unlocked, you can slide it out of its holding slot in order to put a new one in place. There should be a few screws holding the blade in place. Remove these and you should have your new blade ready for installation.

Step 3: 

With your new blade in hand, line up the screw holes on the bottom of the circular saw with those on top of the blade and press them into place until they’re flush. Make sure that when you install your replacement blade that it lines up perfectly with all other parts of the edge guide system because this could cause problems while operating if it’s aligned or defective by even a fraction of an inch. In order to keep the blade from moving while you finish tightening your screws, use a screwdriver as a lever against one of the screw heads and press down so that it holds the blade in place.

Step 4: 

Once your screws have been tightened to secure your new blade, you can put the safety lock back into place over it and set your saw back upright by flipping it over. Plugin your Skilsaw and enjoy working with a fresh new blade!

How to remove the old blade?

You can loosen the tension of the blade by using a hex key which you can get from the hardware store. The blade will automatically come off.

  1. Use hex key (Allen wrench) to undo tension bolt (counterclockwise). You should be able to remove or slide out the broken saw-blade.
  2. To replace the blade, slide the new blade into the circular saw. Pay attention to the way it is facing as well as its placement in relation to other teeth on the blade. These should be lined up with those of any others nearby already in place, and all should face outwards from the center of your circular saw.
  3. Tighten tension bolt back up (clockwise).
  4. Repeat the steps above if you would like to add another blade.

How to attach the new blade? 

You can attach or replace the blade by following these steps:
  1. Place the saw on a stable surface, like a workbench. If you are working with the Skilsaw on your workbench, make sure to unplug it first so that you don’t accidentally start it while changing blades.
  2. Make sure the saw is in the OFF position.
  3. Use an Allen wrench (hex key) to loosen the blade bolt, which is located next to the saw blade. The hex key must be able to fit all the way into the bolt head; do not try using a smaller tool than what’s recommended for your Skilsaw.
  4. While holding the saw blade in place, rotate the blade bolt counterclockwise to loosen it.
  5. Slide or pull the broken blade away from the Skilsaw. If it’s too difficult to loosen the blade without twisting or turning the saw arm itself, you can use a wrench to help loosen it up. This is helpful if you have your Skilsaw mounted onto a work table.
  6. Slide the new blade into position with the teeth facing outward. Pay attention to how it’s placed in relation to other blades near it, as well as any other teeth on your saw arm itself. These should all be lined up properly with one another so that you can operate your Skilsaw safely.
  7. Tighten the blade bolt back into place by turning it clockwise with your hex key.
  8. Make sure to test out your saw arm ahead of time by pressing its ON button and operating it forward and backward a few times so that any remaining tension from the loose bolt will be relieved before you begin using your circular saw.

How to fix a saw blade?

  1. You can use a tool with a flat end, like an Allen wrench or a flathead screwdriver, to remove the blade from your saw. To do this, place your tool on top of the hex key head and press down gently to create some pressure that will hold it in place. Then, use your other hand to turn the hex key in a counterclockwise direction until you feel tension and resistance, at which point you can slide or pull out the saw blade.
  2. To install the new blade, make sure it’s facing in the right direction, then push or slide it into place while holding back any tension that might be there. Make sure to secure the blade into place by using your hex key to tighten up the bolt that holds it in place.
  3. If you need help loosening or tightening bolts for any reason, try borrowing an Allen wrench from a friend or neighbor if possible. If not, you will be able to find one at your local hardware store.
  4. Make sure to disconnect your saw from its power source before working on the blade.
  5. If you don’t have a hex key at home, try using a couple of flathead screwdrivers instead. Simply place one on top of the bolt head and hold it in place there, then use another one to turn the bolt counterclockwise to loosen the blade.
  6. If you are having trouble loosening screws or bolts, consider using a hammer as a last resort to loosen them up. Hit the bolt head with the flat end of your hammer at an angle, which should make it easier to remove screws or bolts that are stuck in place.
  7. Make sure to use a hammer to pound in any bolts or screws that are being installed.
  8. Be sure to read the manual for your saw, since it should have all of the information you need about changing blades and operating your saw in general.

Tips for keeping your saw blades in good condition

  1. After each use, make sure that your saw blade is clean and free of debris. Debris can dull the blade pretty quickly, which means you’ll be forced to work with a duller tool than before.
  2. Keeping your blades oiled will prevent rusting, which will keep them in good condition for many uses.
  3. Check the alignment and tension of your blades after every use. If they seem to be off or broken, replace them as soon as possible.
  4. Over time, even brand new blades may become worn down or start to lose their sharpness. You can find replacement blades for your circular saw at your local hardware store.
  5. Make sure to store your blades in a dry place, which will help prevent rusting and keep them from wearing out in the future.
