Adjust the bit torque by changing the driving-in length of the torque adjustment ring at the end.
The relationship between torque scale and torque is as shown right, in the torque diagram. The figures of torque
scale do not in dictate bit torque values. However, the clamping torque of screw itself is different from type, size,
material of the screw and the material of its mating part. Use it as a standard to obtain an appropriate clamping
torque.
The [Return torque method] in which once-clamped screw is returned with torque wrench or the like is available
as one of torque control methods. However, note that the measured values by the return torque method generally
appear in 10% - 30% lower than the actually clamping torque.
The torque checker measures the torque of screwdriver. The clamping torque of screw itself is different from the
clamped conditions. Understand the correlation between clamping torque values and the torque checker values to
perform the torque control properly.
CAUTION CAUTION
CAUTION CAUTION
Also in reverse rotation, the clutch is turned off in such manner as in normal rotation, stopping the motor running.
Accordingly, when returning the screw tightened at a large torque, set it to a higher torque scale.
