Customer Questions & Answers

Use converter

Drawing 1440 watts, will this saw work well using a converter attached to the truck battery for a power source? JT
Asked by: JT
This will need a 2000+ watt converter for it to work using that power source.

What kind of oil is used to install a blade on a circular saw?

I bought a 13 amp Ryobi circular saw for some small projects, and instructions all say to oil the washers when first installing the blade, but I'm not sure if there's a special type of oil to use because none of the instructions indicate what type of oil to use and my saw didn't come with any oil. If I'm told to use any oil, I'm liable to use Olive Oil, but have a feeling that would get me laughed at. lol. Will WD-40 work?
Asked by: OsideDIY
I'm not laughing; it's a legitimate question. Short answer is yes, but 3-in-one, or a drop of motor oil, even if snagged from the dipstick of your car would be much better. Longer answer includes why you do it at all and how much. Why is to keep the washers from rusting to the blade or arbor when long unused and in damp conditions. How much? A thin film is all you need. Lube them, dab the excess off with a paper towel and install. Any more just presents a problem: you don't want the blade to slip and stop every time you try to cut something. As always, protect your eyes, hands and ears when using the saw. They're a lot more important than anything you're working on. By the way, I have this one and love mine.

how do I engage the spindle lock

Asked by: Patrick
Thanks for the question Patrick! You should hold the spindle lock button while you are using the blade wrench to remove the screw. You will feel it lock once you start turning the screw counterclockwise for removal. You have to keep constant pressure on the button. If you have an issues, give us a call at tech support at 1-800-525-2579.

Customer Reviews

12-Amp 7-1/4 in. Circular Saw is rated 3.9 out of 5 by 142.
Rated 4 out of 5 by from Excellent DIY Saw I bought this saw to help me reconfigure and refinish my deck and for different odds and ends projects around the house. For my purpose, it does the job very well. Since I don't need to use the saw very often, I wanted to buy the lowest priced dependable saw. I believe this is it. I didn't bother w/ the blade that came with it and bought a diablo 24 tooth instead at the recommendation of others here. The only slight downside is that the saw is heavy (for me) and it does show it's lack of power during some harder cuts. (But you do get what you pay for.) All in all, excellent buy for those not looking to spend a lot of money.

Rated 4 out of 5 by from A pleasant surprise My first time using the product was truly a surprise.I have been doing various forms of building all of my adult life,and I swore by some of the so called "better brands". As it turns out,those "better brands" are merely a reputation due to the length of time that they have been doing business. I am not going to sit here and tell you that this fifty dollar saw will stand up to the rigors that a two hundred dollar saw will,but for the price you won't be disappointed. I do this type of work for a living and it does everything I ask of it.If you're a do-it yourselfer ,you've found perfection without breaking your bank account.

Rated 4 out of 5 by from If you don't buy oversized, you can afford more. I know that this is not a forum for wood-bound philosophy., but hear me out. After years of buying Godzilla-level tools for an imaginary future need, I realize that the best tool is one that fits the needs you have. I'm a DIY guy. This really strong little circular saw is lightweight, compact, and right sized for the needs of a homeowner. I'm not needing this to frame out a few houses; I need to cut lumber for outdoor household projects every summer. Put a thin kerf carbide blade on this, as I have, and it'll pretty much do anything you ask of it. Be realistic...don't ask it to plunge cut 5/4 seasoned oak floors quickly. (and NO, I didn't :)

Rated 4 out of 5 by from Good general purpose saw First and foremost don't use the blade in the box. It is beyond terrible and you'll think your saw is weak/defective/broken if you do. I tried to use it to cut some 2x4s and the saw was struggling. I put on a cheapie 24-tooth blade that I bought just in case and it was night and day difference! The first task with this saw was to remove the old rotted deck that the previous owner installed at my house. This saw had no problems (with the non-stock blade) cutting 2x4s and 2x6s for extended periods. Cuts were nice and clean even with a 24 tooth blade. Second I switched to an abrasive blade to cut some small pieces of tile for a back splash in my kitchen. The saw worked perfectly for this process and I was able to quickly make my tile cuts. The saw actually tilts if you need that functionality. I don't and found it slightly problematic because the screw came loose on the front and I had to find a way to rig it so that it wouldn't tilt. There is a lock button you can told down to keep the blade from moving along with a tool to unscrew the blade that makes changing blades very easy which I do like. As my summary says this is a good general purpose saw. I wouldn't recommend it for anyone who is doing saw intensive tasks all day as it does get a little hot during extended use.

Rated 4 out of 5 by from A cheap saw that held up to abuse! I was a bricklayer for 20 years and I also built some homes, so I am use to professional equipment and tools. I sold everything when I changed professions, so when I had to knock out a wall at home due to ants I bought cheap just to get the job done. It worked great for the home repair and I have since used it to cut out and replace all the windows in the home. In addition, I did a blue stone patio at home and for a friend (total of about 900 sqft) using this saw to cut the stone w/a diamond blade. I also did a full fireplace block rough in and put fake stone on the outside w/real stone on the inside, mica slate hearth, block foundation for a mobile home, and a wheel chair ramp. I think it needs new brushes as it hardly runs, but for the price I am on my way to get a new one for another project.

Rated 4 out of 5 by from Great product for the money I volunteered to make a cub-o-matic for our cub-scout pack. For my idea I needed a to cut some plywood. For the small project I didn't want to spend a lot of money so, I bought this Ryobi. It was dependable and worked great. On to the next project!

Rated 4 out of 5 by from Great product for the money. Very economical. I bought this circular saw to cut pavers for a patio that I was building with 1 3/4 inch thick pavers. The saw worked great to cut the 1/2" to 3" pieces that I needed. I did, however, buy a special blade for cutting brick before I started. Fairly easy to use but a little heavy.

Rated 4 out of 5 by from Good Saw, Bad Blade As with other reviewers, don't even bother with the blade included! Right out of the box, I used it to test cut a 2x4, and it seemingly worked well, but when I went to do a crosscut along the bottom of a door that I was trimming, it jammed about 6 inches in. Then I remembered all of the reviews and warnings about the saw blade. So when you are purchasing this saw, which I do recommend, buy a new blade while you are at the store!
