2.2

Basic safety notes

07.00|0889002_ROTA-S plus 2.0 with jaw lock |en-US

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.

2.3

Basic safety notes

07.00|0889002_ROTA-S plus 2.0 with jaw lock |en-US

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:
