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
you need a surge current capacity equal to at least double the motor running current sometimes triple then your battery and cables on the low voltage side must be able to supply that current witch is gonna be a lower efficiency so my advice if you have a problem even if you got the start up current on your invertor would be to add a capacitor in parallel with the invertor say something to the tune of 5 farads to give you the starting current you could likely do with less but more is better in this case other wise it causes more ware on your electrical system and do not forget to leave the truck running or you will kill the battery less the 10 minutes invetor stops and then the truck wont start done you might want to think about an alternator upgrade anything less then 200 amps is just risky really 300 amps would not be over kill

How many watts does this saw draw?

I will be using a generator to power this saw and I need to know how many watts that it draws. Thanks.
Asked by: Bud
i would figure 1440 based on it being 12 amp multiplied 120 if the voltage dropped to 110 it would be 1320 I would figure it for 1500 for the ease of the math and a small safety margin always best to over estimate your draw a bit on this type of thing

saw starts as soon as i plug it inwithout using start trigger.

I don't have the manual.
Asked by: Rosie
the triger switch is likely shorted could also be the wires that attach to the trigger but 99.99 percent its the trigger switch its a mechanical issue most likely not an electrical one but rather its the actual switch or the plastic trigger that pushes on the switch its an easy fix if you have the skill to take it apart and put it back together I would advise against using it in the current condition as its a bit unsafe but unlikely to to over heat and or catch fire or shock you if used for short cuts using the plug as a power switch in a pinch on a job site you could still use it if you really had to but get it repaired or use another saw is the best option this might the part and DO NOT test until completely reassembled and make sure its unplugged before you attempt any service or make sure the battery is removed

Customer Reviews

12-Amp 7-1/4 in. Circular Saw is rated 3.9 out of 5 by 142.
Rated 1 out of 5 by from Use a hand saw instead This saw gives the brand no justice. I hand to check twice to make sure the blade was facing the right direction. Most saws need to be pulled away from the material, this one seems to run away. Ironicly I purchased another Ryobi tool the same day and it works better than perfect. Sadly you can get more use out of an 18 volt Ryobi than this tool. I had to use a hand saw to finish the project. Don't get me wrong Ryobi is a good brand, however this particular product needs alot of reengineering.

Rated 4 out of 5 by from Low-use good performance We won't need a circular saw very often, so we got this inexpensive model. It worked very well for cutting boards for a workbench we recently built. We bought an additional blade to cut plywood, which also worked beautifully. If (like us) you have never used a circular saw before (or it was very long ago), I highly recommend reading the manual for some important safety tips. It's both clear and thorough. It takes a little time upfront, but will save you from damaged wood and possibly injuries.

Rated 4 out of 5 by from ok for the money I bought this for light, around the house projects such as making a coat rack with cubbies. The included blade is not very useful unless you are making very rough cuts. I wanted some precision and cleanliness to the cuts so I puchased a better blade and am now happy with its performance. Its heafty, plenty powerful, built well, adjustments are easy, and its a great buy for the price. My only complaint is the notch for lining up your cut - its just too far off the actual cut line. The only bright side to it is that it leaves excess on the finish piece so you have extra room to plane/sand.

Rated 4 out of 5 by from Greate saw but not the included blade I checked the reviews and found some negative comments on the saw. Because the saw is really a great deal I want to give it a try. After making a rip cut the saw began to stop and go and the blade was really HOT. The blade got burnt marks everywhere and it could not do any cut further. After checking the HOT issue online I realized the issue was caused by blade,not the saw. I spent $10 and bought a carbide blade. Right away the saw cut lumber (ripping cut) as if it cut cheese. So if you think (I do) $29+$10 (new blade) is still good deal please buy it.

Rated 4 out of 5 by from Great value This saw is a great value for an entry level or general purpose tool. Although in the low price range for circular saws, it had plenty of power to cut through 2x8 material. Depth and angle adjustments are typical and uncomplicated. Be aware that it has two types of washers that secure the blade. This is not a problem, just something I've not seen before.

Rated 3 out of 5 by from Gets the job done I purchased this to mainly cut 2x4's and plywood which it did just fine. Only problem is when I tried to use it to cut a countertop it started to angle the cut due to a loose shaft. I still use this saw for framing but not for countertops.

Rated 4 out of 5 by from Ryobi 12 amp circular saw Good circular saw for the money. My only two complaints: 1) the retractable blade guard is made of plastic instead of aluminum (no big deal considering price point), and 2) the alignment sight at front of saw is definitely inaccurate. Other than that it works like a champ. Used it with a diamond blade to cut stone, and with a wood blade to cut over a hundred 2x4s and dozens of plywood sheets. Still running well.

Rated 4 out of 5 by from good qaulity for the price I have owned mine for two years now and used it every day. it still works and noly need to replace due to me droping it from a ladder. great tool.

Rated 4 out of 5 by from Good product for the money. Easy to use right out of the box. Bought an extra blade for smoother cuts and was easy to install.

Rated 2 out of 5 by from A little weak I think... This saw seemed to heat up fast and bog down just as quickly for me. I gave it a fair shake due to other reviews posted here but have to say that I am less than impressed with the performance of this saw. While the saw reluctantly cuts through a 2x4 it is almost useless when ripping 3/4" plywood. This saw would heat up and the blade would stop rotating resulting a in nasty kick back. I used it for about half a day, returned it and purchased a Bosch. Treat yourself and go with a Bosch.

Rated 4 out of 5 by from Ryobi Circular Saw Was perfect for building shelves in my garage. Cut through multiple 2x4's and 1/2 in plywood sheets no problem. It was also very affordable. I would recommend for use on simple projects.

Rated 2 out of 5 by from Not so good I purchased this saw because i have the cordless ryobi circular saw that was very impressive. Unfortunately and amazingly, this corded one is not as good. I gave it two stars which rates as fair since the price is low, otherwise i would say poor. I would spend another 20 bucks and get a craftsman saw or other brand. This saw was no better than our 25 year old black and decker 10amp

Rated 5 out of 5 by from Love it! This circular saw is being used daily, we are in the midst of a renovation. It is working beautifully, we've had NO issues at all. I would recommend this product to anyone looking for a reliable saw, that has the force and power to help you get the job done. Great value.

Rated 5 out of 5 by from Great product and great price I've always been a fan of Ryobi tools so i went straight to this one. I bought this saw to trim the bottom of some new replacement interior doors to fit them in the door frame. Cuts clean and straight. I have not used the blade that came with the saw yet. I bought a 60 tooth blade for a cleaner cut. Power seems sufficient for the job. Great product for the price.

Rated 2 out of 5 by from Cheap price not a great quality I was using this tool to cut OSB board to lay a subfloor down. It seemed to work well in the beginning but by the 5th OSB board (cutting a straight line) the motor burnt up. I knew I should've purchased something a bit higher in quality.

Rated 5 out of 5 by from Good value The saw is a good value for the $$$. I have several saws in different locations. This one fits the bill for doing light remodeling or new construction work for a couple hours. It's too light weight for a full day of ripping and sawing. Oh yes - the original blade is good for about 30 minutes. Buy a good carbide blade and you'll be pleased.
Date published: 2010-01-30
Rated 5 out of 5 by from Amazing saw for its price! If you want a simple DIY saw as everyone mentioned this would be simply it. It would not be a bad idea though to upgrade to the 13A one or higher. The blade that comes with it is absolutely horrible. Get a diablo saw blade or something of that nature it will make a night and day difference!!
Date published: 2013-01-10
Rated 2 out of 5 by from Not stable Blade tilt seems to be inaccurate; When set at zero (normal), the saw consistently pulls to the left when cutting . . . it's impossible to make a long straight cut on a sheet of plywood. Only good for cutting 2x4's or the like. I'm returning it.
Date published: 2013-09-20
Rated 5 out of 5 by from Great saw Great Little saw. Not meant for professional construction but does great with around the house jobs. Always have good luck with Ryobi products.
Date published: 2013-12-17
Rated 4 out of 5 by from Good value for the money Bought this for some small home renovation project. As some reviewers noted, the original blade that came with the saw wasn't that great. Haven't replaced the blade yet but will have to replace it soon. Otherwise, it works very well with adequate features.
Date published: 2013-01-23
Rated 5 out of 5 by from Great Saw Great price and great saw. This thing cuts everything I throw at it at and keeps on going. However, like others have mentioned I highly recommend purchasing another higher quality blade before leaving the store. The one that comes with it is junk.
Date published: 2012-08-21
Rated 3 out of 5 by from You get what you pay for I made my first cuts a few years ago with this saw, doing the occasional doghouse/treehouse type projects, which it was perfect for. Now that I use a circular saw at least once a day, I've had to upgrade. Still, not bad for a 30 dollar saw.
Date published: 2010-01-26
Rated 5 out of 5 by from Terrific value. I bought this saw as a disposable--to cut mortar joints in foundation. It just keeps on ticking and it has become my primary wood cutter. Will run the wheels off of it. For the price, I can't imagine a better value.
