Question about Saws

Open Question

I have a Jonnesway JAG-6612 Air Angle Grinder that looks to be in good condition, but little power. What parts commonly fail in a grinder? Where can I get a manual? ( the Jonnesway website has no Tech. support section, and the Contact & INquiry pages are both broken and don't work) Who sells parts?

Some of those double insulated power tools have a remote switch. By remote I mean that the piece you push, or pull does not actually have a switch on it, but has an arm or rod that could be several inches long, and that arm or rod actuates the switch.

If that 'arm' which is usually plastic breaks, the unit won't turn on (or in some cases off)

I have had a Dremel tool and a haircutting clippers that did exactly what you describel

Make sure it is not plugged in, then remove the phillips screws holding it together. Many times there is one hidden and you have to look for it.

Gently -- Gently separate the two pieces of the body. I like to do this over a white beach towel so that any pieces that might jump out at me won't go far and be easy to spot on a white background.

Look for an arm that reaches towards a switch --if it is broken it will be obvious.

I repair that kind of break with JB Weld. Don't get the quick dry JB, but the 'normal' product. Quick dry gives you almost no 'open' time.

Just mix a tiny dab of material from each tube together on something non-porous e.g. a piece of scrap ceramic tile, broken dish, glass, mirror and put a little of the mixture on each part of the broken area.

Put the two pieces together and let dry -- for 24 hours.

Re-assemble and you are home free!

I always have a plan for clamping or propping the repaired part so that it won't move BEFORE I mix the epoxy. That way I am not scampering around trying to find what I need whilst trying to hold it together.

Many times I use a tiny screwdriver and dip it into the mixture and apply it with the screwdriver. As long as you wipe the screwdriver clean with a paper towel it will be fine.

good luck.

check inside for any loose connections plus check the brushes. if like you say it is smoking it could be a trip to the wheelie bin for that one.

I have a 7" angle


There are 3 versions of the 7" grinder model 4074. Sears Parts Direct has the manual for sale http://www.searspartsdirect.com/partsdirect/part-number/BLACK-DECKER-Parts/Grinder-Parts/741333-00/0009/900/Model-4074/1228/0721050?keySuffixId=NA&productTypeId=x&searchModelNumber=4074&subCompDesc=Unit%20parts&brandDesc=BLACK&DECKER&modelDesc=7 .

Black and Decker has pdf versions of the manuals for many of their products are here: http://www.blackanddecker.com/manuals.aspx . However, check the model number on the grinder. 4074 doesn't come up as a valid model. The usual model numbers start with alphabetic characters to indicate the type of tool. The site lists where to look for model numbers.

I hope this helps.

My makita grinder was working just fine wile I was grinding it just quit on me and now it will not even start


You can try removing brush covers and brushes to check and clean as needed.I have a makita grinder and have to change brushes about every two years but I use mine a lot in very dusty conditions.I think that I would probably check on/off switch about first as I have had mine do exactly what you have and I replaced the switch and it's still working.I have had mine for 15 years.Great little grinders. If you feel comfortable doing so you can bypass swith to make sure motor is good. Best of luck and thank you.

Yep - probably dust build up - have you tried one of those cans of compressed air used for blowing stuff out of computers and stuff. They have a bit more blow than you and a small nozzle to get right it.

Can i change the brushes on my cordless grinder?


Hello u2okay, it is a little challenging but, Yes you can. I have done it myself some time ago. I no longer have the information available, but, I went to the manufacturers website and got a list of their authorized parts dealers. That was 8 or 9 months ago and she's still running strong. Well worth the effort. GREAT TOOL!
Good luck my friend!

Grinder runs about 2 minutes then shuts off. I replaced the heat sensor- no change. What else could be the problem?


check the condition of the brushes, make sure not sticking in the brush tube and also look at the commutator for a really dirty surface.
