Torque Adjustment Operation
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 the Spring 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. Also in reverse rotation, the clutch is turned off in such manner as in normal rotation, stopping Rechargeable
motor running. Accordingly, when the screw tightened at a large torque, set it to a higher torque scale.
The number from zero to eight on the Torque Scale are reference number only and not an indication of actual torque
output.
