Additional Chuck Safety

Entanglement. Entanglement with a rotating

chuck can lead to death, amputation, broken

bones, or other serious injury. Never attempt

to slow or stop the lathe chuck by hand,

and always roll up long sleeves, tie back

long hair, and remove any jewelry or loose

apparel BEFORE operating.

Chuck Speed Rating. Excessive spindle speeds

greatly increase the risk of the workpiece or

chuck being thrown from the machine with

deadly force. Never use spindle speeds faster

than the chuck RPM rating or the safe limits

of your workpiece.

Using Correct Equipment. Many workpieces can

only be safely turned in a lathe if additional

support equipment, such as a tailstock or

steady rest, is used. If the operation is too

hazardous to be completed with the lathe or

existing equipment, the operator must have

enough experience to know when to use a

different machine or find a safer way.

Trained Operators Only. Using a chuck

incorrectly can result in workpieces coming

loose at high speeds and striking the

operator or bystanders with deadly force.

To reduce the risk of this hazard, read

and understand this document and seek

additional training from an experienced

chuck user before using a chuck.

Chuck Capacity. Avoid exceeding the capacity

of the chuck by clamping an oversized

workpiece. If the workpiece is too large to

safely clamp with the chuck, use a faceplate

or a larger chuck if possible. Otherwise, the

workpiece could be thrown from the lathe

during operation, resulting in serious impact

injury or death.

Clamping Force. Inadequate clamping force

can lead to the workpiece being thrown

from the chuck and striking the operator

or bystanders. Maximum clamping force

is achieved when the chuck is properly

maintained and lubricated, all jaws are

fully engaged with the workpiece, and the

maximum chuck clamping diameter is not

exceeded.

Proper Maintenance.

All chucks must be properly

maintained and lubricated to achieve

maximum clamping force and withstand

the rigors of centrifugal force. To reduce

the risk of a thrown workpiece, follow all

maintenance intervals and instructions in

this document.

Disconnect Power. Serious entanglement or

impact injuries could occur if the lathe is

started while you are adjusting, servicing, or

installing the chuck. Always disconnect the

lathe from power before performing these

procedures.
