To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out.

•
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.

When it is difficult to insert the bit, pull the sleeve
and insert it into the sleeve as far as it will go.

After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
