If you turn the spindle to the right, the indicator pin (item 17) will
protrude from the chuck body (item 1) (gold-colored pin) shortly
before the stop.
WARNING
If the indicator pin protrudes, the entire serration of the wedge
bars (items 5 and 6) no longer engages into the base jaws. The
base jaws are not sufficiently engaged by the wedge bars.
Risk of injury from jaws and workpiece being flung out.
•
If the indicator pin protrudes, do not clamp the chuck and do
not start up.
Important notes
When working with a very short opening stroke or large series,
lubrication grease may be pressed out between the loaded
surfaces of the chuck gear. In this case efficiency will decrease!
Following a number of clampings, activate the chuck several times
without a workpiece inserted at full stroke so that the grease can
be distributed evenly again on the sliding areas on the inside of the
chuck. The chuck will then attain its full clamping force again.
•
Never remove the base jaws without actuating the thrust bolt
(item 14).
•
Tighten the chuck regularly during processing to compensate
the loss of clamping force due to vibration.
•
Following a longer period of shutdown (more than 8 hours),
always re-tension the clamped toolholder in order to
compensate for the spindle settling and the resulting loss of
clamping force.
•
When gripping the spanner wrench, do not tighten with an
extension pipe or using hammer blows. Only grip using the
flangemounted chuck!
•
Do not flange-mount the chuck against the edge of the chuck
body!
•
Never clamp the base jaws outside the marked lines
•
Do not use force (e.g. hammer blows) to move jaws that are
difficult to move. Clean the guides and jaws.
•
Subsequently delivered hard top jaws (type SHF) or unsplit,
hard jaws (type STF) must be ground in the chuck for run-out
accuracy.
