How to install a blade on Black and Decker 20 volt cordless circular saw 

*This is my second DeWalt circular saw **MyBest.Tools** I sold my 18 volt and use the money to help purchase this 20 volt. Money well spend. I liked that it came with a blade as well.*

This is why I love the internet, because of people like you. Bought this little saw to do some simple construction and was scratching my head trying to figure the dang thing out, felt like I was going cross eyed trying to make sense of the manual 😵 Thanks for putting this up, it was quick, informative, and accurate.

Just glad I'm not the only one that couldn't figure this out lol

Thank you. The manual had plenty of instructions on the stupid battery but nothing on installing the blade. This video really helped.

I’ve had my saw since lock down and today (January 2024), your video helped me finally install the blade. I couldn’t figure out the washer. Thanks.

Instructions on the manual was poor. Thanks this helped. I am right handed and looks like this saw is for left handed people because the blade should never face you when cutting. I bought it from amazon.

Thanks! The instruction manual was not as obvious as I would've liked. This video helped me put the blade in my new circular saw in just a couple minutes.

Thank you so much for this video! I hate instructions for some tools. They make things so complicated. Now I can cut my own wood for my projects instead of going to the big box stores and waiting until I get home to find out it was cut wrong.

This was really useful. I just bought this and the instruction manual didn’t mention the tool, OR the break button. Thanks

Thank you so much.!! I couldn't make heads or tails out of the instructions. You made it very easy!!

Thanks. I thought I understood directions in the manual, but easier to see in video. I just watched another video where the guy did this while battery was in the saw!

black and Decker should pay people like you for showing us how to use their products. thanks dude.

Hell, I was cussing up a storm just trying to find a wrench to fit this thing( of course, it's on the saw itself), and it still kept spinning around. Useless manual! Thanks for showing me the light.

Felt like an idiot reading the manual, thanks for the quick video, worked for me!

Thank you! The manual for it did not help at all. The pictures and words did not tell me what to do. You just earned a sub.

Thank you Jonathan! I read the instructions which made no sense, but you explained everything perfectly!

Thank you dude! I was looking for an Allen wrench in my house and couldn’t find the right size, I didn’t even realize there was one on the tool :)

OMG Jonathan -- I was about to take back the Black and Decker CS1250 as I just couldn't understand how to add the blade. The instructors didn't mentioned about there being a hidden button! thank you so much! Happy 2022 to you my friend!

You are a life saver! I didn't know what/where the spindle lock was and after 5 minutes of turning without any progress I turned to RU-vid hahahaha! So grateful for your video.

I looked all over the manual for how to replace the saw blade. Thank you for a quick and helpful video. All i was missing was the little plate that comes off. You are awesome.

I saved this to watch any time I need help with my saw.

Thanks for this. Apparently I’m an idiot and needed this vid to figure it out

Nice short and to the point, well done. Now I can cut some wood!

Thank you! Single mom trying to DIY and this is my first time trying to use a circular saw, you helped tremendously!

Excellent video! After I watched your video I was able to install the blade on my circular saw in 2 minutes. Thank you!

Finally a video that is concise and gets to the point!

Thank you. I was stupid and didn't think to pull out the plate after the unscrew. Makes much more sense now. :D Thanks!

Thanks for the quick video! 💪🏽

Very good video. You made it look so easy slipping the blade in from the bottom. I must have been trying to put it in from the top somehow. Took me a while.

Love when someone is all about getting it done! Thank you Sir!

Thanks for this just bought their bundle set and i haven’t touched a tool in years felt dumb trying to do it and figured if it takes more than 30 seconds RU-vid it

Thank you - couldn't find instructions in manual

Thank you so much, I just couldn’t figure out how to lock it so I could unscrew it!

Thanks for making this video because the instructions were not clear.

Thank you for the video! Helped me out. I appreciate it, brother

Best video hands down. Thank you!!

Easy Peezy! Thank you! 😊 What a great little video!

Thank you. Visual is way better than directions. Now, off to start projects.

Thanks so much for the video. Why in the world does the manual not include these instructions?

This was great. Quick and to the point, my back deck thanks you Sir!

Thank you for making this. The manual dropped the ball on removing the washer. Ugh.

Thank You , I could not find how to install the blade in the instruction booklet.

Thanks for making that so easy! Came here after reading the manual lol

Thanks! Did not like written instructions.much appreciated!

Good job , thanks,,,now I know how to get the ?!** Blade on.

Thank you so much I’ve been at this for over an hour than found your video; those directions suck ; thanks 🙏

I appreciate this so much I sae instructions and I did not get it

Thank you so much!! This was so much help!!

Thank you for your video 😀👍

Awesome video...exactly what I needed!!

Thanks for your help.

Thank you. So much easier than trying to follow written instructions. 😊

Thank you for posting!

Thanks for making this.

Thank you for getting right to the point 👌🏽

Thank you! Very helpful.

Very helpful! Thanks

Great work, thx!

Very much appreciated sir.

Same sentiment as others. Thanks man.

I think I love you. Perfect video!!!

Easy is what I saw. Thx

So helpful !

Right to the point thank you!

It is righty tighty lefty loosy with a left hand saw. I about stripped the bolt till I figured out you have a right hand saw.

Thanks for this video..

I need to change the blade inside but I can’t get it off. I am holding the button down but the blade keeps spinning and I can’t unscrew the bolt.

My hands are not big enough to change it. Maybe my son can do this when he gets home from trucking. (Mine is the corded model). This also explains where a certain little piece of metal came from in the box. The picture in the manual was not so clear as this.

Thanks man!

🎉 🎉🎉🎉 Thanku! Instructions probably weren't bad but I didn't understand it 😅

Thank you!

Thank you! the directions had such tiny writing and no clear indication of 'here this is where to start'.

Good stuff

Thank you kindly 👌🏾

Thanks so much

Thanks!!!

Thanks broski. ✔

My B&D 18v cordless doesn't have an obvious blade lock button. I've looked all over it with no result. Have you used one of these and know how to install a blade? There is no blade currently on it to lock in place with vice grips.

Thank you

Thank you.

I missed where is the blade lock so I can tighten the bolt ?

The little tool is an Allen wrench.

Bless you!!! 😊

This saw is supposed to have a 3/8 (9.5mm) arbor, right. I just bought my first blade for a 3/8 arbor and it will not fit over the arbor shaft. It is close but no cigar/ is it ok to grind outa very small bit of the blade so it will slip over? I figure that may lead to blade balance issues? Any ideas? I am having a heck of a time getting the blades past the guard to remove or install them. The video shows it being a 'wiggle', this is more like a full on bending the guard and WRESTLING the blades off and on. Anybody else having that problem? Thanks for the video.

I have the firestorm cs144 14.4 volt and there isn't a button to push to lock the blade. Aw man!!

What size arbor.

I still cant get the balde in,its 140mm blade right?

My dad always told me to keep the plastic on the blade an let it come off its self funny to see some one else do the same thing people that didn't learn from youtube

What size bolt go in to lock blade in?

Thanks. Lol. Straight forward review

😎👍🏿

thanks

my high school theater department thanks you. The written instructions were not helpful😂

Mine doesn’t have a button smh

thank you thank you thank you. Yes I'm a handyman dummy

The manual just loved to tell me for 15 pages not to stick the battery in my butt and light a roman candle but wouldnt give me any clear pictures on how to install the only part of the saw that really matters. Thanks black and decker

What arbor is that? Like what's the name of the arbor shape. I'm used to 'diamond arbor' blades... what's the circle-with-the-sides-lopped-off shape called? How do I get one if I don't know the search term nor the word to use when vocally asking in person at a brick-and-mortar hardware store? I could just go look at the circular saw blade section and grab the one that looks right... but when I go... inevitably they will have them but they will be out of stock on the floor, as they are all in stock in the back room... forcing me to ask the associate for the ones I'm looking for... that's just my luck. P.S. My language skills have nothing to do with my ability to be safe with dangerous tools. _(I'm preemptively cutting off that almost obligatory comment about how someone's worried about me, because I'm too dumb to operate a circular saw... obviously I know enough to try to cut that off so maybe I'm not as dumb as my question may make me seem.)_

Thank you! So irritating that it's not in the instructions...

Still have difficulty installing the blade - I followed this video, but I can't seem to "wiggle" the blade into place because the nut that goes in the middle of the blade is too "tall" to where it makes it impossible to slide the blade into the plastic guard. Unless I bend the plastic guard, I am not seeing how yours was so easy. Oh yeah, the manual SUCKS!

Perfect video; the manual on these is about useless!
