Notes on particular risks
This product may pose a danger to persons and property if, for
example:
•it is not used as intended;
•it is not installed or maintained properly;
•the safety and installation instructions, local applicable safety
and accident prevention regulations or the EC Machinery
Directive are not observed.
DANGER
Possible risk of fatal injury to operating personnel if a jaw
breaks or if the chuck fails because the technical data have been
exceeded and a workpiece is released or parts fly off!
•The technical data specified by the manufacturer for using the
lathe chuck must never be exceeded.
•The lathe chuck may only be used on machines and facilities
that fulfill the minimum requirements of the EC Machinery
Directive; specifically, they must have effective technical
measures to protect against possible mechanical hazards.
DANGER
Risk of fatal injury to operating personnel from clothing or hair
being caught on the lathe chuck and being dragged into the
machine!
Loose clothing or long hair may become caught on projecting
parts of the lathe chuck and be drawn into the machine.
•The machines and equipment must fulfill the minimum
requirements of the EC Machinery Directive; specifically, they
must have effective technical measures to protect against
potential mechanical hazards.
•Always wear tight-fitting clothing and a hairnet when working
on the machine and the lathe chuck.

WARNING
Risk of injury due to dropping the chuck during transport,
installation or removal.
•Take special care in the danger zone when transporting,
installing or removing the lathe chuck.
•Note the relevant load securing regulations for working safely
with cranes, ground conveyors, lifting gear and load-handling
equipment.
CAUTION
Risk of slipping or falling if the chuck's operational environment
is not clean (e.g. contaminated with cooling lubricants or oil).
•Ensure that the working environment is clean before starting
assembly and installation work.
•Wear suitable safety boots.
•Follow the safety and accident prevention regulations when
operating the chuck, especially when working with machine
tools and other technical equipment.
CAUTION
Risk of limbs being crushed when opening and closing the chuck
jaws during manual loading or unloading or when exchanging
moving parts.
•Do not reach between the chuck jaws.
•Wear protective gloves.
•Follow the safety and accident prevention regulations when
operating the chuck, especially when working with machine
tools and other technical equipment.
CAUTION
Risk of burns due to workpieces with high temperatures!
•Wear protective gloves when removing the workpieces.
•Automatic loading is preferred.

Basic safety notes

07.00|0889002_ROTA-S plus 2.0 with jaw lock |en-US
CAUTION
Risk of damage due to incorrect choice of clamping position for
chuck jaws on workpiece.
If an incorrect clamping position is chosen for the chuck jaws on
workpiece, the base and top jaws may break.
•Make sure that the workpiece is clamped concentrically.
•If the chuck has a quick-change jaw system, the top jaws must
not protrude beyond the base jaws in the radial direction.
Exception: The supporting jaw variant 3 protrudes beyond the
chuck base jaw due to its design. In this case, the T-nuts
always need to be completely inserted into the groove of the
chuck base jaw.
CAUTION
Hazard from vibration due to imbalanced rotating parts and
noise generation.
Physical and mental strains due to imbalanced workpieces and
noise during the machining process on the clamped and rotating
workpiece.
•Ensure the chuck's axial and concentric runout.
•Check options for remedying imbalances on special top jaws
and workpieces.
•Reduce the RPM.
•Wear hearing protection.
Notes on safe operation
•Do not start the machine spindle until the workpiece is
clamped and the spanner wrench has been removed from the
chuck.
•Only operate the lathe chuck when all protective equipment
has been fitted and is in full working order.
•Check the lathe chuck at least once per shift for externally
visible damage and faults.
Functional test
After installation of the lathe chuck, its function must be checked
prior to start-up:
