Overheating means that the user is applying too much force on the tool. It works great when you don't try to force it.I had the same problem when I first used mine. My tool actually started smoking! Then I put less force on the tool and the job came out a lot nicer and the tool didn't heat up. I still have the same sonicrafter tool that started heating up real bad, and it still runs great. I didn't even have to send it in for repairs after the blade started smoking. I use it often for drywall repairs, cutting aluminum vertical blind header rails, sanding door jambs, and all-around repairs at the apartments I manage. Really great tool!

Lori, you can ask to replace your tool just to see if that will make a difference. That's what I did and the replacement was same. I haven't tried the REAL thing, Fein MultiMaster to compare but, I think, Rockwell is just made to work this way. Although nothing came off due to vibration on mine. Good Luck!

my product overheated very quickly..couldn't hold it and yet it is a HAND tool!!! Vibrations cause fitting to come loose. Won't even cut through nails or ply wood. It was supposed to make our job easier but instead just made it expensive and frustrating

I wish I knew, because this is a common problem. But I have a suggestion. When you are done using it, donot turn it off! Turn it on the coolest setting, zero I think, and let it cool down with air blowing through it. About 45 minutes. Otherwise you will burn up the heating element!

I haven't had an issue with this overheating. I have left it on the hood of my car for an extended period of time. However, I am sure there is a limit to how long you leave anything on a bark surface in direct sunlight. I don't think you will be disappointed.

The manual suggest to use mineral sprit-type materials only. Do not use material with a flash point lower than 70F. Paint thinner outta work for a cleaner of oil base paint. I don't know if WD 40 would have ill effects on seals, o rings, and such. Should be fine for metal parts. Remember to use the anti-freeze type liquid when planning to stow away the machine else the aluminum parts will corrode and rust togeater calling for a tear down of the parts. WD 40 is good for everything-I've never damaged anything using it.

You should put some dabs of grease on the shank where it goes into the collet/bit holder, and of course should wipe the shanks clean when the bits are removed. There's nothing else that I've ever done, and it works great. If it gets really dirty near the ventilation slots, blow it or vacuum it clean. That's mostly what the manual says (you can download the manual for free at the Bosch website). Eventually the motor will need to have the brushes replaced, but that's true of any electric motor -- and I've never had to do that for any tool (since I don't use it many hours a day, five days a week). Very, very well made and trouble free tool.

Yes, it is right but be careful. run 30 seconds at a time. we burned the motor working a heavy batch of wet ingredients.

The motor has a thermo cut out to protect the motor If you put to much down pressure the motor will heat up the motor faster, try using mild pressure and see what happens. I did not run my saw that long, project was small and the saw worked great. Good Luck!!

No you cant warm it in the mirowave .... it will spark cause of the metal can .... and no you cant use stips cause this type of wax is hard ..... and it should be easy to pull off ....u always have to leave a corner lifted to be able to pull off ...

I would say to proceed with caution, but I was able to get his hand off after strategically placing his left arm in front of a small space heater for 3-5 minutes. When the hand felt semi-soft and more pliable, I was able to pop it off and place the gauntlet hand on. If the paint job on yours seems solid, warm/hot water might be a better option.

Mine overheats in about 15 minutes, even in cool spring temperatures, even on freshly mown, dry grass with the dethatcher set on its highest setting. You have to let it cool down for 20 - 30 minutes before the electric motor will restart. It would take a long, long time to de-thatch a half-acre. When it's running, it does work quite well.

It isn't supposed to damage the metal since it dries relatively quickly. I was nervous about it though and did cover the metal parts as best I could (using plastic shopping bags or glad press n seal) and tried to concentrate the spray on the crystals. You could always spray your cloth and then wipe, or even fill a small cup with the liquid and sort of "dip" the crystal parts. If it is something antique or very important to you, I would remove the crystals to clean them. I haven't seen any ill-effects on my metal parts after using this. I don't clean it too often ...a few times a year maybe. I just dry-dust it the rest of the time. It isn't supposed to damage the metal since it dries relatively quickly.

It took me 3-4 hours, using the right tools like a fuel line removal tool. It shouldn't take too much longer if your doing it your first time. Instructions are pretty easy to understand, just have a clean work space and there should be no problems.

Just be sure to get a heavy gauge extension cord, which aren't cheap, but will preserve the electric motor and keep full electrical flow to the motor. Outside of that its just scraping off dirt and inspecting for lost tines. But that shouldn't happen until after a lot of uses. Don't pull it backwards. And always read the manual.

Michael good morning, this is the tool for the job. I stated in my review that I cut a couple of hundred feet of the champion metal roofing. practice first on a piece of scrap or the coversheet, after a couple of feet you will get the hang of it. I wore ear plugs. cut all mine in the same location and used a roller magnet to clean up after. Best tool for the job and the price was right.Good luck and have a fun time. You can rotate the cutting head so that it is 90 degrees to the body then you can use two hands for better control.Ron

I have not used it since only using it twice on a foot injury. Takes at least 6 hours to get to operating temperature.

Same thing here also. I was concerned that mine might be defective. Probably should not say this, BUT, I just had to open it up, very carefully, and check it out. The motor wasn't hot or anything. The motor was an open face, made completely of metal, and was not hot to the touch. Looks like it should last for a while. The smokey residue was from the brushes. I have used it 2 times afterwards, with no apparent problems, and the smoking part is not as much. Works fine for me!!!

I'm not sure of an exact amount of time, I've used it for around two hours sometimes more. But if you turn it off between colors or cleaning, I don't think it should get too hot. I do have mine off the carpet though, I would recommend allowing air to flow around it. But overall I haven't burned my hand on it or anything like that. I hope that helps you.
