Are there any risks if I use impact wrench to loosen lug nuts while the tire not touching ground?

That would be correct. There should be no issue of using the impact with the wheel off the ground. You are exactly right in that the tire should be on the ground when using a breaker bar or tire iron. ...

What fasteners should not be loosened using an impact wrench, and why?

As the name suggests, impact wrenches have the ability to impart high amounts of momentum change. The delivery of this momentum change is hard to meter, so it is quite easy to damage: soft metals ...

What is the disadvantage of using impact sockets on a hand wrench?

Impact sockets I have had were thicker than standard sockets so there may be a few locations which are not accessible with impact sockets. But I think the primary reason is to get customers to buy two ...

Removing stuck bolts- manual ratchet vs. pneumatic impact ratchet

Impact is better. It vibrates and reverse hammers in between each hammer (weakly). This helps break up corrosion that may freeze a nut in place.

While you run the risk of breaking the bolt in either case, I've had good results using an impact driver when removing such fasteners.

Can a manual/hand impact driver be used with sockets?

Can I use the "Auto" mode on my Hercules impact wrench to safely put lug nuts on?

Bottom line is, you can pretty much use your tool the way you want to use it. The real question is, should you? Basically, no you shouldn't. Even in the Auto-Forward mode, it would be way too easy to ...

How much can be achieved with a manual impact driver?

I have one of these and I don't recall that it ever worked for me. These days the cost of an electric impact wrench is so low that I wouldn't fool with one of these.

A cross type lug wrench will work better. You pull up on one side and down on the other so it only applies torque with no bending moment as your wrench. Crosses have 3 or 4 different size sockets , ...

Impact Wrench Mystery – breaks loose axle nut, but can't undo wheel lugs…

Each of the impacts is like a mini lever having a go at the fastener. If there is a longer lever, ie larger socket, there will be more force applied for the same torque applied. So, in some cases, ...
