Turn the collet nut (8) clockwise to tighten the collet nut (8)
u
securely onto the accessory mandrel.
Note: The collet (7) was designed to be hand tightened and
loosened only. Accessories naturally self tighten during use.
A wrench is provided with the tool for loosening. You should
never need to tighten the collet nut (8) with a wrench. If a
wrench is needed, use only the wrench provided. Do not use
tools that will mar the finish and could break the collet. Always
ensure there is some accessory in the collet before tightening.
Tightening an empty collet can crack it.
When finished, release the spindle lock button (6).

Note: If an accessory causes vibration it can usually be
improved by loosening the collet nut (8) , pushing the
accessory in as far as it will go and rotating it 1/4 turn then
retightening the collet (7).
