Re: Concrete Saw For Residential Basement Floor Cutups


I have a Husqevarna electric 14" saw for indoor work. I always bring my own power to the site after having a breaker popping issue on a site that had me ready to throw the saw through the window.

We used a gas saw to cut an opening in a foundation, from the outside, and still set off the smoke detectors in the house.

Re: Concrete Saw For Residential Basement Floor Cutups


I had a project a few months ago, I built a tent around the area that was to be cut, I had a demo fan air in and another fan out, with gas cutoff saw, water, and a shop vac, and even with gass mask, I felt wossie that night,

electric saws get bad reviews....otherwise thats probably a smarter way to go...

ive got a few jobs coming up where i need something more than a jackhammer and dont want to spend 8 hours jackhammering

advice?
The K760 is actually a really good saw for indoor use. Virtually no dust and only leaves a very small trail of slurry no puddles or big mess. Only thing you have to do is make sure you are on a 20 amp breaker as the saw draws 15 amps. If the home I'm working in doesn't have a 20 amp available I install one or bring my generator.

Any of you dumb dumbs that run a gas tool indoors should seriously reconsider. You are supposed to be professionals so let's conduct ourselves that way. Carbon monoxide can linger in the home long after your done and possibly affect other occupants of the house.

Re: Concrete Saw For Residential Basement Floor Cutups


I always sub it out. I mark up the sub. So I see this as two options:
1. Check-in before and after the process, make some money and go work at a different site or in the office while the sub does the work.

2. Spend 4-8 hours on grueling, backbreaking work that I absolutely hate and make the same amount of money, IF all goes according to plan.

Option 1 all day, baby.

Someone usually only breathes 2stroke fumes once in a home, that stuff lingers for days.

I like the sub it out idea!

They don't make masks for running a gas saw in confined spaces.

Just like Seven said. Don't ask me how I know.

Hydraulic wet saw all the way.
Yup. I've never done it until I was working for another company.
It was embarrassing! HO was complaining of the smell on 2nd floor.
I ended up getting laid off for refusing to work.

I have not done a thread on this company yet... too much to write.. haha

Re: Concrete Saw For Residential Basement Floor Cutups


Are you cutting all the way through? I have found that cutting all the way through is not always necessary. I remove a section by cutting all the way through, but after the first piece is out, scoring and sledge hammering so it looks neat on the surface is adequate. Pulling dirt out from underneath the area you are hammering helps to break it out.

Good idea.

Re: Concrete Saw For Residential Basement Floor Cutups


thanks to all for the good advice

ive got the gas saw out of my consideration

i think for now we will just keep jack hammering, but for the garage job that turns into living space---ill rent a walk behind to try it out....no way im hammering 4+" of concrete with steel reinforcement.......its a large area too......i can open windows and make a mess

Re: Concrete Saw For Residential Basement Floor Cutups


I used an air powered walk behind on a project, it worked well once we figured out that 150' or so of hose was too much, the saw had no power. When I called the rental place to complain they said it doesn't work well with over 50' of hose.

I said thanks for telling me when I asked you to send it out with 200' of hose.

We had to hand walk the compressor through the customer's yard to get close enough.

I have not tried that saw, but it looks good, and being a Hilti, I'm sure it's a great tool.

I've tried the hilti system and IMO it's crap. 2 much dust escapes the vac system and even the self cleaning filters become clogged to quickly.

I would suggest trying using a dust deputy. Cutting concrete produces an incredible amount of dust and when you lose suction obviously it will create a lot of dust.

Re: Concrete Saw For Residential Basement Floor Cutups


NJGC @ # 23: Your are confusing a 2 stroke K760 (76cc) gas 14" demo saw with the K 3000 Wet ( has a GFI in the cord assembly) a 14" electric ~15 Ampere 120 volt saw.
