• Place the plate on the pinion in the housing and turn it slowly until it engages
in the pinion gearing.
• Place the guide segments in the housing.
Note
The number of guide segments depends on the size of the rotary indexing
table (see table).

Make sure that the upper rail of the guide segments is not pressed down in
the housing. The balls of the guide segments must run between the rails, as
otherwise the plate may not be able to move and the balls of the guide seg-
ments and the rails may be damaged.
Note
When screwing in the clamping ring, the plate seal may be drawn into the
gap between the plate and housing.
If this happens, pull the plate seal back out of the gap before screwing the
clamping ring in further. To do this, insert a flat and blunt object under the
seal beside the drawn-in area and slide it along the seal until all of the seal-
ing rim is resting on the housing.
• Tighten the clamping ring using two pin punches and a hole profile
(or another suitable lever tool).
Note
To tighten the clamping ring, the rotary indexing table must be held in place
(if necessary with the help of a second person or by securing the rotary
indexing table).
Note
The correct pretension of the guide segments is achieved when the index
hole (arrow) is level with the screw hole and the clamping ring is flush with
the plate surface.
For design reasons, sizes DHTG-65 and DHTG-90 must have two screw holes.
The correct pretension is achieved with the hole noted during removal.
