To adjust the torque on these screwdrivers. Proceed as follows :
1.
Determine the torque output of the tool by checking a tightened fastener with a torque wrench.
2.
Increase or decrease the torque by rotating torque Adjusting Ring. Rotating the Ring clockwise
to a higher number on the torque Scale increase torque output while rotating the Ring
counterclockwise to a lower number decreases the torque output.
3.
Check the adjustment with a torque wrench. A number of factors will affect torque output from
one job to another. Final torque adjustment should be made at the job through a of series of
gradual increase. Always start below the desired torque and work upward.
4.
Adjust the bit torque by changing the driving in length of the adjust ring at the end.
5.
The relationship between torque scale and bit torque is as shown Ring, in the torque diagram.
The figures of torque scale do not indicate bit torque values. However, the clamping torque of
screw itself is different form type, size, material of the screw and the material of its mating part.
Use it as standard to obtain an appropriate clamping torque.
6.
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.
7.
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 perform the torque control properly.
1.
In reverse rotation, the clutch is turned off when a screw is tightened at large torque, set same
or higher torque to unscrew.
2.
The number from zero to eight on the Torque Scale are reference number only and not an
indication of actual torque output.
