In order for the tool size to be changed, the collet
3
and the reducer
2
must first be adjusted.
1. Remove the tool
5
as described in
2. Completely unscrew the clamping nut
4
from the spindle
1
.
3. Replace the collet
3
and the reducer
2
.
The reducer
6
is used for the tool’s length compensation and stop position, as well as a square wheel
driver. The inner square (yellow) includes the tool square end, and the outer square (red) is seated in the
square end of the spindle.
4. Select a reducer whose length and inner square are a suitable fit for the tool to be used.
5. During assembly, ensure that the groove (yellow) of the collet engages with the eccentric
7
forming
(yellow) of the clamping nut
8
. Only this will ensure the proper functioning of the collet.
6. When inserting the tool with the reducer
2
, the collet
3
and clamping nut
4
in the spindle
1
,
ensure that the square end of the tool locks into the inner square (yellow) of the reducer
6
and its
outer square (red) locks into the square end of the spindle by slightly twisting the tool.
In the case of tools with a shaft diameter of 8 mm and a square end of 6.2 mm (e.g. an M8 threading
tool), the reducer is not used
6
. The square end of the spindle
1
is used instead.
