To install these types of driver
bits, follow the procedure 2.
(Note) Bit-piece is necessary
for installing the bit.
Procedure 1
For tool without one-touch type sleeve
►Fig.10: 1. Driver bit 2. Sleeve
To install the driver bit, pull the sleeve in the direction of
the arrow and insert the driver bit into the sleeve as far
as it will go.
Then release the sleeve to secure the driver bit.
For tool with one-touch type sleeve

sleeve as far as it will go.
Procedure 2
In addition to Procedure 1, insert the bit-piece into the
sleeve with its pointed end facing in.
►Fig.11: 1. Driver bit 2. Bit-piece 3. Sleeve
To remove the driver bit, pull the sleeve in the direction
of the arrow and pull the driver bit out.
NOTE: If the driver bit is not inserted deep enough
into the sleeve, the sleeve will not return to its original
