SKILSAW Mag 77 Worm Drive Circular Saw - Complete Maintenance And Repair Guide 

I'm happy to see pros teaching the basics to people thanks Vince and vcg.

One of the great things about Skil saws....they are 100% user serviceable; which is why you’re able to pass them down from generation to generation. Also, parts are readily available as well, you don’t need to go hunting for parts, as you can find 99.99% of the parts anywhere they sell the saws. Heck, you just basically did a full tear down in this vid, cuz it’s THAT easy😁 Super great vid Vince & Nick✌🏼

over the years I have picked up several "non working" saws at thrift stores or yard sales. I've paid about10 bucks new switch, brushes and a little oil and BAM working saw for about 25 to 30 bucks.

I think a bearing replacment video would be a good idea for content on channel as wheel as helpful information for others

Thankyou for this video !! Very helpful on your step by step instructions I’m a DYI guy and needed to tune up my 77 & change cable! Keep up the great work.

Never checked mine in many years.cuts like a boss

Thank you for a very simple yet good display!

Great job I have a old one and just got a 81/4 table saw worm drive and love it. Thanks for the tips great job.

Most impressive Vince! Great video!

What an awesome video and it’s sunny in the UK too... have a great day

First time viewer here, gotta say, this was great. Not only informative, but concise, and dare I say entertaining. I learned what I needed to learn, the oil change, and learned what I wanted to learn, the cord change out (plan on putting a 40' cord on my saw soon) got everything I needed with one video. Bravo! Subbed!

You are a superb instructor.

This was a very informative video. Well Done.

Found one at a yardsale for $10 with a mangled power cord. You gave me all the info I needed.

Thanks for the great video. Most concise, easily understandable video I’ve seen. I have an early 80’s saw I bought brand new. Going to service it and enjoy doing it, now that I know what I’m doing.

I have a 5.5” Skill saw. I love it. I wish they continue to make it anymore.

Nice job Vinny!!

I could see were someone could think this video is common sense. However this could really set up a new guy to look good on a first day of work. Not everyone knows how to do regular maintenance tasks. Great video

Vince, Great video and info on the saw 👍🙏❤️

Great video and sharing your knowledge! Looks like a great saw!

Yo, Vince!! Dang bro! You just did like 3 vids in one!!👍Thanks! Nice touch with the 12v drill even for the precision work. Thanks again and God bless again! 😁👍✌

should be an oil level indicator on there made from hardened glass or something, checking the oil before use would not be any issue.

Thank you bro I didn't know how to change the oil

Skill saw is the best framing saw and the mag 77 is the number one

Rooight on! Thanks for the video 📹

Thank you very much amigo..

I actually got a blade from skil that was backwards. Had to turn it around. Kinda weird. Good point on telling about direction of the blade. Awesome saw

Great Video >> Thank You!!!

Thanks sgain! I didn't know about the oil. Only knew to change the brushes when the saw quit. Have had the saw for 17 years, using it here and there for DIY projects. Better get some oil and change it, before using the saw again. I have a 17 year old Dewalt 12" Miter saw that has served me well with no maintenance. Could you do a video on the maintenance for a Dewalt 12" Miter Saw? Bet any of yours are long since worn out. Lol

Great video Vince brother

Great video 😊

Thank you for sharing the great details

Great video, for sure must be best saw on the market but as I live on other side of the pond I have never used one. I’m planning a visit state side soon and plan on buying one even if I have to post it home. I noticed in another post below it’s a bad idea to run it of an extension cord so is replacing the cord that comes with the saw for a much longer one the answer? Cheers

The great thing is that this applies to all saws. New series Tool maintenance

After nearly 2 weeks of research--because I don't like buying things without researching the crap out--I purchased my first circular saw; a Skilsaw 7-1/4 In. Lightweight Mag worm drive. There's a feeling I have when I've finally found the one that checks all the boxes. This saw checks all the boxes and feel completely confident I bought myself the best circular saw for my needs for the money. That being said, I'm wondering there's a video about bearing service on this saw for future reference; expanding my knowledge to be prepared. I like to know as much as I can about these things because I always prefer to do my own service and repairs on my gear, whatever it is.

Excellent video 👌🤪

Big help!

good vid! subscribed... hope this keeps people from putting blade on backwards....

That diamond trick for the blade is very useful

Happy Monday everyone! Another good video! 🌞😎😍 🧰

Just ordered my first one ever last night. I’m in CT, I’ve literally never seen one in person here.

Finally uses the right oil .... Still someone out there that like " u should this oil ( insert random oil type ) instead

Yes how do you check the bearings? Just bought my first skill saw from a pawn shop. It is older than yours, is a monster and runs well! However, I have no idea how many hours it’s worked nor what kind of treatment it was given. It’s definitely been around the block a few times considering it’s looks, for sure. I’m very proud to own it. Noone better touch it! LOL Thanks L

Years ago, before I knew better, I smoked a good Skill Saw because I ran it on a long cheap extension cord. Every new trainee should be taught about voltage drop and what it means.

you just made RB very happy by doing this video 😂

I don't own a skilsaw, but I appreciate the video.

Number 1 baby!

Pleass show us how to replace the bearings, thank you for the content

I was disappointed to find that my brand new saw came with a very low lube level. Afraid to cause damage to it, I waited for the lube to come in (special order) and filled it up. The manual is not specific about setting the saw on a table with the blade down. I assumed that I should hold it with the fill spout level, which meant holding that saw at an angle. That's also how I filled it. Did I potentially over-fill it?

"big bottle of lube"... haha sounded like a line from Superbad.

A friend of mine let me borrow his mag 77. (he's been out of the business for a while.) I checked the oil and it came out like molasses in winter.

Hey bro I have a mag77 skill saw and I can't get the original oil what kind of oil would you recommend for me please

What’s the viscosity of the suggested oil?

Someone needs to check on RB and make sure he's not died and went to corded tool heaven after this here Video! Lol! Yo, it is my opinion that every carpenter should have at least one of the mag 77 skilsaw's. Skilsaw is the legendary saw that built America. We have several that still run flawlessly! Have had to replace brushes due to intermentent power loss. It was just carbon build up. But went ahead and threw them new brushes in. Like 2 min with cleaning the contacts up. Easy peasy. I gotta say, since I bought the company the flexy rear handle saws, and now the FUEL rear handle (my new favorite) we just don't use them skilsaw as often. Because we have so many batteries. It's a convenience thing. But the mag 77 was all we used for many and many of years. Personally I still have, and have used for many years, that same wormdrive skilsaw my dad used for years and years and years. He's Pretty sure his boss gave it to him when he was the foreman, before he went on his own into excavation. He doesn't remember unboxing anything so it was likely used. Lol! Seriously, The ol' skilsaw wormdrive is the flagship of all saws. It always will be. Idk about any of newest ones. Whether they are the same quality or not. But I know the quality from 10+ years ago in just unbelievable. Anyone reading this.... You see any wormdrive skilsaw at a garage sale, buy it. Keep it on the shelf if you think you'll never use it. Wait and see, when you do need it, make sure it has a good blade, and use that sucker for ripping some advantech or for cross cutting LVL'S. So comfortable, smooth, and line of sight is on point. Beast mode! Just like @VCG Construction is beast mode! 💪💪 Thanks for the awesome vid cuz! You da MAN! 👍

greetings, I would like to see a vid on the same saw Mag 77 LT, replacing the bearings. thanks

I just bought one after my old school took a shitt after 26 years anyhoo, why does Mag 77 sound like a bearing is going out when i release the trigger. Is that what yours sounds like. I took one back already grabbed another thinking it was just a bad one but new does same .

I think once a week is good for checking the oil. What do you think?

How do you adjust you bearing or clutch ?

I nearly went crazy going counter clockwise trying to remove the blade my first time using one of these. 🤣

Very nicely done !! Hey Vince is there much of a price difference between the worm drive and the regular type? I inherited a regular SKILSAW but I've heard the Mag 77 is the Best. Your thoughts? Thanks again for sharing your thoughts, talent and videos, Rodney

Hey Vince, is there anything on the SKIL MAG 77 saw itself that says it's the Mag 77 and not a regular saw??

Show how to replace bearings. Just from curiosity 😃

It would be great if you showed how to replace the bearings

Damn I haven’t change the oil lib since about one of those beauty tools that’s was back in 2014

Vince the skill saw is I will describe it like a tank very dependable and nothing can compare to this skill saw

Does anyone know why its righty loosey, lefty tighty on wormdrives? The blade would loosen itself off the motor if it were righty tighty lefty loosey. This way when you use the saw the friction keeps the blade on tight!

There’s nothing wrong with brushed tools! I use 25 year old brushed tools that are just fine. I also use a 23 year old brushed impact driver.

Hey Mr. Vince with V.C.G. Construction, have you ever had the opportunity to view the teardown on the A.v.E. channel? I enjoy the content of V.C.G. I think you'd enjoy this. Seems as though you know a lot of things and like to teach about it.

Wait wait. I'm a bit slow at times, but i get it. The M18 worm-drive style circ saw eliminates ALL this maintenance. Except the blade change, of course! 😉 Edit: what happened to your left forearm, dude? It's cut underneath.

Yo fellas! Happy monday and have a positive week.

what viscosity is the oil?????????? Ive had mine 10 yrs and now it is way too heavy to use. getting rid of it.

How do I get to the armature

Hey Vinny and the very cool gang. I watched one of the vcg bids from a little while back.icant remember the video name but if I remember correctly it was in regards to a rumor of people saying the specific tool was running hot. At the end Vinny was yelling "but we heard but we heard we heard we heard" sounded like a deranged parot lmaoo. Does anyone know the video I'm talking about.

Bearings video please

Bro you should maybe briefly talk about that rubber grommet thing right next to the blade reason being piece of wood came up in my garden broke the rubber thing off and then the metal that even hold it on there that be a hard one to know how to replace for these new people being born

First, great vid!

anyone knows how to check if the switch is bad?

Diablo is the Spanish word for "Devil" lol

Learned so much from this video. The problem is, i don't have a skill saw. Please send me that free skill saw that your giving away co'z i can't afford to by one. Watching here from the Philippines.

Good as new skilsaw 🙏✝️🙏amen🙏✝️🙏

You can build a house with a skillsaw 77, framing hammer, tape measure,pencil, level and pry bar, damn nearly. Sawzall is a side kick that's a mini boss. I use the both for everything at work. the basics will carry you far people forget the kiss method (keep it simple stupid).

my father in law hasn't never changed his oil on his skilsaw i don't know how its still working 😆

Now that I know what to do; when I plug 🔌 my saw in ; It Comes ON ! When I’m done ✅ with my cut I unplug it ! Feels so dangerous ! Thanks

The oil in the saw looks aerated

The lube

I bought two tubes of that lube I thought I was a grease I couldn't go wrong cuz they were $0.65 the tube so if you need them so send me your address and I'll send them up to you for free

🙏✝️🙏amen🙏✝️🙏

He didn't finish the explanation of why a dull blade is more dangerous than a sharp blade....... A dull blade takes more effort to push through the material than a sharp blade. What happens when you get to the end of that cut? The material will split like a splittling wedge through a log and all the resistance that was on that dull blade is no longer there. What happens when you're putting maximum effort into cutting and all of a sudden there's no more resistance? That blade is now moving faster than you anticipated and it ain't gonna stop until it hits something hard. Most likely that'll be the bone in your finger. And cuts from dull blades always hurt and cause more damage than a super sharp blade simply because a dull blade rips flesh instead of slicing like a sharp blade.

This isnt a sidewinder😮

Anyone else super bothered by "the saws oil LEVEL" glitch.

Take a shot every time he says "lube". Go ahead, play with your friends. All y'all will be wasted.

Why no ear protection while running the saw!???? Don’t you like your ears???

I just wanted to know what to do to maintain this warm drive skill saw. I just had to replace my switch, so I looked for a video to help, and this guy wants to make a movie out of it, just get to the point nobody cares about your monologue!!!
