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.
1. Also in reverse rotation, the clutch is turned off in such manner as in normal rotation, stopping the
motor running. Accordingly, when the screw tightened at a large torque, set it to a higher torque scale.
2. The number from zero to eight on the Torque Scale are reference number only and not an indication
of actual torque output.
3. The power supplier will generate low power when the button of the power controller is switched to
"LO." Also, the electric screwdriver's torque output setting value should be adjusted to middle torsion
value accordingly.
