Guide Disc Safety Considerations
Warning
To ensure secure and reliable instrument positioning, and to prevent instrument movement
within the revolver or Guide Disc, the central tension handle, the guiding arm's screws and
the Guide Disc must be tightly secured by hand.
Warning
Always check that the Guide Disc is mounted correctly to the VarioGuide and is not tilted
or blocked.
Warning
Always choose a hole from the Guide Disc with appropriate diameter for the instrument (as
small as possible but not smaller than the instrument's diameter, check engraved
diameters on the Guide Disc). In case of using a drill guide tube, choose an appropriate
sleeve diameter for guiding the instrument.
Warning
Inspect the Guide Disc for damages before each use.
