and insert the bit into the sleeve as far as it will go. Then
release the sleeve to secure the bit.
To remove the bit, pull the sleeve in the direction of the arrow

NOTE:
• If the bit is not inserted deep enough into the sleeve, the
sleeve will not return to its original position and the bit
will not be secured. In this case, try re-inserting the bit
according to the instructions above.
The proper fastening torque may differ depending upon the

be fastened, etc. The relation between fastening torque and
fastening time is shown in the figures.
Hold the tool firmly and place the point of the driver bit in the
screw head. Apply forward pressure to the tool to the extent
