BSD-1200 Series
Attaching / detaching bit and bit type
Push up the holder clamp by finger tip, and it will be unlocked. Thus, the bit can be freely
attached and detached (single finger notion type) select such a bit whose shank is equal
to the size shown below.
■
Insert the power plug into a receptacle and set the changeover switch to “
F
” position.
■
Apply the bit to the screw head and press the lever or push main body to, then the
switch will be turned ON to start the motor running.
■
When the screw is tighten and reach the torque that you had set, The tool will stopped
automatically.
■
To reset the tool by releasing the lever to the original position or releasing the bit From
the screw head.
■
To return the screw, set the changeover switch to “
R
” position.
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.
