Reply:Yes, because of the safety factor.Also because it directs sparks in a known direction. I work in a pretty flammable environment. I like to have some idea where the sparks are going."Any day above ground is a good day"http://www.farmersamm.com/
Reply:No, they interfere with where and how I am using the grinder. I have had better luck directing sparks by changing the angle the stone hits the material than I have with using guards. Yes, I know it's wrong, but I am not about to change. I am very carefull not to put the stone in a place that it could be caught or bind up. I did have a stone bind up and kick back taking a good chunk out of my knee once. Ironicly (sp?) it had a gaurd on it at the time.
Reply:The guard stays on at my house, I've seen too many stitches from guys taking them off. The handle, however, stays in the box.- If you can jump across it you can weld it! - anonymous old boilermaker
Reply:Always on. Saved my *a$$(figuratively speaking) more than once due to disk shattering on grabbing. Took it off once due to space limitations and ended up grinding my knuckle when my hand slipped down the grinder body into the wheel......Mike
Reply:Same were as hillco,No with flap wheel grinder, yes on the abrasive disc grinders.I had a cheap abrasive disc shatter on me, cut my hand and gave me a few bruises. I could have been worse if the guard was not on there.Tim Beeker.
Reply:Mine are off. Handles on. I also remove that little safety latch from the paddle switch. I only buy those type on my small 4 1/2" grinders.I have a few of the 7" grinders, one that is 4 HP. Real brute, heavy too. That one can handle a 9" wheel. As with any grinder, common sense and paying attention to what you are doing, is a very high priority. Those metal guards are great, and should be used in most cases, but limit access in many grinding operations. Reason I have them off.BTW. How many folks lay their grinder down ON the wheel? That's a big NO NO. Chance to crack the wheel, or hit the switch while picking up the grinder (if you remove the latch like I do). I ALWAYS lay the grinder down on it's back, wheel up.
Reply:I leave the guard on as well as the handle. Having worked in a Paper Mill all those years we were constantly taught and corrected as to Best Practices concerning safety and the removal of a guard was punishable by time off or dismissal.Construction sites have no tolerance for guard removal in this area.Gordie -- "I believe you understand what you think I said, but I'm not sure you realize that what you heard is not what I meant."

Reply:Removing the guard used to be done as soon as it came out of the box. Now, they are all on. Scar across the gut tells why. (7" Makita) Handles are always on unless in a tight spot. Always lay it down with the wheel up. Do this with grinding wheel, cut-off wheels, and wire brushes.TurkeyLincoln Idealarc 250Millermatic 250Miller Synchrowave 250 Miller Synchrowave 350Thermal Arc PlasmaHH140Miller Diversion
Reply:Guards on ,,,, it is a no brainer. Some local companies allow reduction of the arc of protection. They cut a section of the guard away. I on occasion will remove the guard to get in a tight place then reinstall the guard. That is safer than leaving the guard off all the time.
Reply:I got a nice 4" long scare up my middle finger because of my dumb *** friend and my 5" DEWALT. I have always had the guard on my grinder with harddisks, but take it off for flap (I used the ones with the built in nut so it contacted the guard) Well he took the flap off and put a disk on then sat it down on my bench. With out noticing he did this, I picked up the grinder and flicked it on, the disk caught my glove, sucked my hand in, then processed to grind a 1/4" wide 1/4" deep grove down my middle finger. No blood, but hurt like hell for 2 months. 5 years later you almost can't see the scare now. Still have never forgive him for doing some thing so stupid.Lincoln 300 Vantage 2008300 Commander 1999SA250 1999SA200 1968Miller Syncrowave 200XMT350MPA/S-52E/xr-15Xtreme 12vs Millermatic 251 w/30A Millermatic 251 Dialarc 250 Hypertherm 1250 GEKA & Bantom Ironwokers
Reply:On my 7" Dewalt, it is now on, after it gave me a small slice on the gut, before I always left it off, handle always on it, its too unwieldy without it.my 4 1/2" Dewalt is always on unless I desperately need to get into a tight place with it, the handle is on unless I need it off for some reason, its easy enough to handle with just one hand, and I have big enough hands for that! This is with the exception of an old Craftsman that I have, it runs at a slower rpm and I only use sanding discs on it, and the guard would just plain be in the way!#1.

Reply:My wife is a paramedic, and is our "Safety Director", she is also in OSHA training, so yes, guards are on!

Reply:Guards on. I will take them when the rare occasion arises.
Reply:Mines not on there. I dont use it. Not the safest practice but i usually only use flappers. I use my schools grinders tho.
Reply:Guards off, handle on. High quality Sait disks and wheels, always lay grinder down with disk up, and always start it away from my body, and out of the line of fire. Always treat it like it's loaded.It is certainly more dangerous without the guard...It's a dangerous world.The best piece of safety equipment is a safe operator.Just what I do, not necessarily for everyone. I find guards too restrictive. I don't use one on a table saw either.I do wear a full face shield, glasses, earplugs long sleeves, and sometimes gloves. I hate gloves, and put them in the restrictive category as well.The caveat is that you can NEVER lose respect for the danger of the cutting tool.Last edited by daddy; 04-14-2009 at 08:17 PM.

Reply:Yes the guards are on. The older I get the more the stitches hurt and so on. I am lucky to have all the things that stick out still attached,RobertWilmington, NC
Reply:I don't understand how so many of you have hurt your hands with a grinder. With one hand on the handle and the other on the trigger, there shouldn't be a problem. Worst I have done to my hands with a grinder is wore the finger tip off my glove. It was an inch longer than it needed to be anyway. I one hand a grinder occasionally, but I have a special little cheapy grinder for that. Easily handled with one hand.
Reply:Gaurds off, handles on. I use every side of the wheel so the gaurd is always in the way. I've never had a serious grinder injury.i leave it off on the 4 1/2 grinders and onthe 9" grinder
Reply:Some of us have been using grinders for lots and lots of years so the odds are that you will have a bad day some tine. Someone should start a thread about injuries using a drill press. The most dangerous machine in the shop.Have a nice dayRobertWilmington, NC

Reply:Guard on the 7" Metabo with the grinding wheel, guard off the 7" Metabo with the 5" wire cup brush because it won't fit. Handles on both. Safety thumb button on both also. The cup brush is the one that makes me nervous, those little wires can easily penetrate skin an inch or more. One time I had something that felt like a sliver in my arm, so I worked it until there was some sticking out. Pulled out a piece of wire 1-1/2 inches long that must've been there a while because it had turned black. It had to have gone through at least the long sleeve cotton uniform shirt I wear every day.
Reply:[QUOTE=Pipeliner;273529]A "Most Dangerous Machine in the Shop" thread would be neat to hear the stories.Here's mine on the drill press. I had my head up my a$$ one day. Rare form, but happens occasionally. My press has the single belt / adjustable sheath setup. There was a 3/8" bit that was at least 12" long chucked up. Can't remember where I got the bit or what I was even doing with it. Early in the A.M. standing there drilling a hole, I look up and read the little tag that says "Run though speed range daily". I never do this, but like a complete and total dumba$$ I reach up and twist the speed control up slowly. As I go faster the bit started to flex. Startled I let go of the speed control handle. It proceeded to go to max by itself. The bit bent almost 90* before it started hitting the press column and stalled out. Windmill is what we called that in the shop. It could be heard over the other machines and everyone knew what had happened.I knew a fellow that lost his first finger in one in just an instant knocked it right off. RobertWilmington, NC
Reply:Off of the big Black and Decker and off of the little Bosch....Altho this might be a good time to re-introduce the OSHA approved grinder guard for all you guys that keep stickin your fingers where they shouldnt be--- Attached Images
Reply:Too FunnyGreatWilmington, NC
Reply:I can only remember one job where I removed the guard. I was grinding out some fiberglass in the hull of my catamaran. I had to reach through a 6" hole, and the entire grinder was enclosed. I was pretty much grinding blind with a 4" grinder; grind a little, blow it out, take a look to see what I had done, grind some more...America Needs AMERICA'S Oil!!!"Global warming is the greatest scam in history ...There is no run away climate change.

Reply:I've made one of them special OSHA approved grinders before. I've been guilty of quickly "putting away" an unguarded grinder before. Personal tools were never checked so when the safety guy shows up, I always had an empty drawer waiting.
Reply:I removed the guards because they were in the way.The only incident i've had was pluggin it in with the switch in on position and grinding the backs of my fingers.Lincoln 225 ACLincoln Mig Pak 15Lincoln Mig Pak 10Purox Oxy-Acet Outfit20 Ton PressHonda Generator

Reply:"Now look at the locations of where the injuries are"Guards to not guard against stupid or careless. As seen in pics 1&2. Our safety guy was always concerned about "pinch points", but lots of guards actually create pinch points that were not originally there. We were also supposed to guard all moving parts on a drill press. He was laughed at, told where to stick it, and eventually gave up.
Reply:Only time I take the guard off is when I'm using a wire cup brush. On a 4.5" grinder I choke up, index finger from one hand is right up against the guard. I've actually worn out guards before, one rivet on the tension mechanism snapped, and another I simply wore the corners down from using it as a pivot to grind across the face of fillet welds. I've never come across a situation where the guard was in the way and prevented me from grinding what I needed to get to. When grinding edge on, I use the side handle almost all the time. I do for heavy grinding too, but usually I just reach straight for a 7" or 9" grinder (guard + side handle 100% of the time) rather than waste time and effort playing with anything smaller. I use ZA resin discs with a rubber backer far more often than anything else. Typically don't use the side handle, but if it's on I won't bother taking it off until it is in the way. I use the newer small body DeWalt 4.5" 11amp with paddle switch. Next time I'm looking at buying a new one, I'm going to seriously consider a higher amp model with paddle switch. The DeWalt is a good unit, comfortable to use, quick change guard, but I do wish it had better cooling and more power.

Reply:I have had one or two misshaps. the most memorable was when I was grinding a frame for a trailer and slid my hand a little too close to the wheel Thank god I had gloves on and yes I wear gloves almost all the time I am working with metal. I have found that leather doesn't bleed and I do. I have been hit with flying wheel bits from a disc and was glad I had my leather apron and cape on as I only had a small bruise from it( I was not the one grinding just happened to be close to him and he tipped the grinder to one side and pinched the blade.I have made a few mistakes when working but the best thing I ever did was to buy a pair of safety glasses one day. I bought them for sun shade but they ended up saving my eye. I was using an air nailing gun to nail down 2x4s when the gun double fired and the second nail lodged in the right lens of my safety glasses less than 1/4 inch from my eye The worst one was when I worked at a truss factory as maintinance man. The wall line air gun quit working and they asked me to look at it and like a dummy I just stepped in front of the gun and started looking it over when a guy bumped the wall laying in the jig and POW . When I looked down I had a 16 penny nail with only about an inch sticking out of me just below the belt in my stomach The guy just took off running cause he knew I was but I was more angry at myself for being so stupid in the first place than I was at him. So pay attention the life you save may be your own.[SIGPIC][/SIGPIC]weekend metal melter and all around pain
Reply:TEK, that Osha guard had me howling. I just finished a ten hour Osha course online for work, and it all fits together.
Reply:Guards on, always. I work with an old timer with one eye, pirate eye patch and all. You want to guess how he lost his eye? Yep... he had a cracked disc without knowing it. The disc blew apart and went through a face shield taking out his eye and leaving a horrible scar. Now instead of working on cars, he works as a warehouse guy for our company. It's not worth it, really.
Reply:I always use a guard with cut discs, especially this one! Attached Images
Reply:Yes, guards are ON...HSE (Health, Safety and Environment) formerly OH&S (Occupational Health & Safety) levies HEAVY, HEAVY fines here in Alberta for each grinder on site without a guard.They DO however allow reduction of the total size of the guard, so all of mine are cut down to the minimum 120° sweep.In addition to the 7" and 9" brutes, I use 5" Makita grinders, the lighter 9005B, and the heavier 9015DBZ - Both have gun triggers - I REFUSE to use the 9015DB with the friggin' Paddle Trigger (Death Trap) 'cause it's an accident waiting to happen.I have modified several guards to allow me to safely use different sizes of disks on the grinders....The 9005B has guards for both 5" and 6"The 9015DBZ has guards for 5", 6", and 7"Before you ask, NO, I do not run 7" grinding disks on a 5" grinder, but it comes in handy to sneak into a tight place with a 7" Zip Cut, or a Stringer Bead Wire Wheel.As for the arguement that the guards "Get in the way..." I either keep my guards loose enough that I can bump them on the bench to rotate them as needed, or, I am not so lazy that I cannot walk to my toolbox and grab a screwdriver.Opinions vary,Have a Good Night.Later,Jason

Reply:Guards on, handles on. You'll get written up on any of our job sites without one.
Reply:I have guys who work for me in the shop.I pay workers comp insurance for them, and if they hurt themselves working for me, its my responsibility, both morally and financially.No, I wouldnt have to pay all their bills, but you can bet my state insurance goes up if somebody gets hurt who works for me.So I insist on guards, and I go around and put em back on, whenever I find a grinder with the guard removed.Its one thing to just cut yourself- then, only the taxpayers have to pay for your unemployment, health care, and taking care of your family when you cant work.But if you are an employer, even, like me, with only a couple of guys, you would be crazy to leave guards off of grinders.I have to say, the only time I have ever sanded the skin off my hands, or ground slots in myself, its been using other guys grinders on job sites where the guards were pulled off. |
