The protective hood of your angle grinder is not correctly fitted and is defective - what do you do?
I am not working with this machine. Only the correct fit of the protective hood and its perfect working condition offer 100% protection.
I just remove the defective protective hood and continue working.
It does not matter, I can still work with it.

I may not use this disc with the angle grinder because the speed is too high.
Only when the disc has worn down to a diameter of 115 mm.
Yes, but I must first remove the protective shield from the angle grinder so that the disc fits.
Question 5
What are the ideal working clothes when grinding?
Sandals, shorts, T-shirt, sunglasses
Protective clothing such as shoes, mask, eye protection, ear protection, hand protection
Anything, as long as my eyes are protected.
Question 6
BFlying sparks are produced when working with cutting and grinding discs. What do I have to watch out for?
Nothing.
I must hold the angle grinder so that the sparks hit me and do not fly off into the surrounding area.
I must make sure that no persons or objects are at risk and that there are no highly flammable or combustible materials near where I am working.
Question 7
