Also compliance with the regulations for laser equipment. Search the HSE website.

Does the documentation / manual specify the class of laser used ?

Things that must be dealt with.

(1) shielding and / or interlocks to prevent any laser light leaving the machine. ( but still wear suitable googles )

(2) safe removal of fumes created by the material being cut. ( these can be toxic / inflamable / corrosive )

Hi , its 40w laser and has a lid with a little srew. I'll defo be wearing suitable safety glasses.
There is a extractor fan included but it has same plug as the machine so im just going to get a different extractor or use one of my dust extractors to push the fumes outside.

Condition 6 is a bit odd ?

This image comes a seller in Bremen in Germany
 
Yea like that machine, just checked the tracking info and it came from Germany.

Location portsmouth but based in china but item came from Germany, confusing stuff.

The laser is cooled by clean water that runs through the tube i think. There is small water pump with the machine
 
Ground connection on the back of machine but i thought that was for the US style system with 110v.
I thought if the plug was earthed then this ground connection doesnt need to be used?

The Attention item 1 suggests one has to check the water is flowing before opening ( operating ? ) the machine. This could mean there is no flow sensor to remove power to the laser emitter should the water flow cease. It is the water flow that cools the laser emitter and without water flow the emitter will quickly overheat and if not destroyed will be seriously degraded.

Just another cowboy seller on eBay.

Well - what could possibly go wrong with, or be dangerous about, a cheap 40W laser engraver?

Question for you - was this a lot cheaper than ones genuinely made and sold in Europe? If so, do you think that the difference in price is entirely down to profiteering on the part of the expensive maker(s)?

I see what you mean there, i think it must mean operating.There seems to be lots of youtube vids on this machine so ill double check the instructions with other users hopefully. Not sure about it having a flo sensor but i dont like the sound of things overheating, ill look into this.

Not sure there is many others available in Europe, i just seen this and thought it would do nicely for engraving small wooden items so went for it.
A year ago id probably would of just plug this thing in without thinking but I try to be a little more carefull with electrical items these days
 
Don't plugs have to have a BS (EN?) number and be tested too?
Only a BS number (BS1363) as they are built to a British Standard, not an EN standard. That is a good thing to look out for on a plugtop when portable appliance testing, if it is a regular BS1363 plug with an EN number or a CE marking it is likely counterfeit.
The adaptor in the original post is a dangerous one as they don't contain a fuse and as others pointed out, it doesn't earth a schuko plug.
Lots of info here: http://www.bs1363.org.uk on plugs, adaptors, leads etc
