You can use impact wrench with adjustable speed and impact power. Or screw it with your hand.

 

Makita and Hitachi have cordless impact drills with adjustable speed option.

Did the LUMU break the screw?

Damn Lumu!

Too much power!!!

[PeteW]

that must have been a lot of power to do that to the screw. damn....

Always hand start your bolts to make sure the threads are not crossed. They also sell torque bars that tire change places use to limit torque.

Did the LUMU break the screw?

Yes,

the power is brushless motor.

I can't completely control it.

[ChrisK]

Yeah, I would probably use a torque drive when working with bolts like that. Adjustable power impact wrenches are a great tool but when you are cranking out a ton of power it can over drive and unlike metal it'll break. I see you got your impact working again?

Fucking LUMU bastards!

I already hate these people, but the entertainment factor is just to good!

[DR99]

It is pretty entertaining.

Though this is a new brand,still growing.

We will try to make the market acceptance of the brand.

@LUMU, where are these made? Maybe you could send one to TiA for a review?

Made in China.

If you need to do,we will be happy.

I don't think that is a bad idea. I would contact Eric or Dan at TiA and see if they could try one out. It would be interesting to see how the tool works out in a video put on by the guys. This is an unknown brand and if your trying to enter an American market it might be worth putting the tool out to professionals like those guys for consumer review.
