first of all (1,950-Inch/lbs ) torque should read (1,950-lbs/Inch ),which = (162.5 Lbs/Ft), so with the no load (2600-RPMs)
u should be getting (80.5) HP , so u should be getting any where from (55-75)HP with hands full of load
which should be enough to loosen most of the par torqued nuts , I gave it 5 cuase i had experience with hitachi impact drive
, it's great , well done hitachi, BTW why didn't hitachi concider the brushless motor wrench , it would have been great , specialy
that the brushless ones out perform the carbon brush motors with at least (12-18)% in total power and energy saving as well
thanks for Amazons GREAT JOBEGet more detail about Hitachi WR18DL 18-volt Lithium-Ion Cordless Impact Wrench.
