Factors affecting tightening torque

Voltage
A
drop in voltage causes a reduction in motor speed, the force and number of impacts,
and tightening torque.
2.
Tightening time
"The tightening time affects the number of impacts. Thus, the torque increases with
time of tightening.
"
Long tightening eventually means no more increase in tightening torque, since the
tool hammer's tightening force and the force of the bolt or nut cancel each other
out.

Replacing carbon brushes
Remove and check the carbon brushes
