## Questions & Answers

**Q: How do you fit the stone bit to the shaft,it says to slip the chuck cover off and loosen the fixing nut.I cant see how thechuck cover comes apart.**
A: You'll find a hole on the side near the chuck, rotate the chuck until the hole lines up and you can put a small screwdriver or the allen key through it, this holds the chuck in place while you unscrew it, put the grinding bit in, then tighten it up again, remove the thing you put in the hole to keep it in place, get to work!

**Q: Does this machine have a soft buffer wheel. Bob**
A: No it comes with a finer wheel and grinding wheel but you can get a buffer wheel size three inch off amazon or the makers

**Q: How do you lock it to change the wheels?**
A: You cannot lock a grinder, The  best way is to brace the opposite wheel.

**Q: We cannot get it to tighten when insert stone bit in shaft. Just goes round and won't tighten?**
A: It took me a while.Fit the big nut to the socket on the right hand side.At the other end of the lead you will see a little hole on the side of the stone socket.Look in there you will see another little hole.Put the small allen key into the hole,it will stop the cable from turning and you use the small spanner to loosen and tighten the chuck.It is easy.

### ⭐⭐⭐⭐ Good product
*by J***N on 27 January 2022*

This grinder is great if you want to save space due to its compact size however I was a little disappointed to find no flexibile shaft in the box which I thought was an included piece when purchasing

### ⭐⭐⭐⭐⭐ Looks well made.
*by B***. on 20 October 2020*

Smaller than expected, but it is well made and runs much quieter than my old grinder, plus the variable speed, polishing wheel and flex attachment are a huge improvement too. I wouldn't say it was built for heavy grinding use, but smaller and finer work certainly.
