it wont break your wrist.Hmmm, bad advice. Better advice would be use the handle as it will break your wrist if you give it the chance, 88Nm of Torque! I have the same set (although with 4Ah batteries), stunning bit of kit and just a 22min charge for 3Ah/ 36 min charge for 4Ah batteries

if you break your wrist you are using it wrong.
no need to use gear1 2 is faster and plenty powerful enough.
i have never used the included handle except on an sds and i won't either.
the only reason i use one on an sds is its more comfortable when chasing
