General Description of Use
Tool Changing
The Gesswein Power Hand Angle Rotary
Handpiece uses a quick-tool-release mech-
anism that allows for rapid tool changes. To
operate, turn the Collet Release Ring coun-
terclockwise toward the arrow pointing to the
“R” or release position (see fig. 2). When in
the full “R” position, the Collet Release Ring
will make a click sound; the collet is then fully
open and ready to accept a tool.
To secure the tool, turn the Collet Release
Ring toward the “S” or secure position.
Again, a click sound will be heard, indicat-
ing the collet is fully closed and the tool is
secure.
When changing tools, be sure that the hand-
piece motor is not running. If you attempt a
tool change under this condition, the motor
will be stalled and damage will occur.
Collet Removal
The Angle Rotary Handpieces can accept
many different size collets (see Specifications).
Standard sizes are
3
⁄
32
" (2.35mm) and
1
⁄
8
"
(3.2mm).
To change collets, turn the Collet Release Ring
to the full “R” position and remove the tool in
the collet. Hold the collet between the thumb
and forefinger and turn in a counterclockwise
direction until the collet is removed (see fig.
3). Insert the new collet and reverse the pro-
cedure. It is best to always tighten a replaced
collet by hand using the Collet Wrench (#510-
0180), securing until just tight.
