Additional Lathe Chuck Safety

ENTANGLEMENT.  Entanglement  with  a  rotat-
ing  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 workpiec-
es can only be safely turned in a lathe if additional
support equipment, such as a tailstock or steady/
follow rest, is used. If the operation is too hazard-
ous to be completed with the lathe or existing
equipment, the operator must have enough experi-
ence 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 bystand-
ers with deadly force. To reduce the risk of this haz-
ard, 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 pos-
sible. 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.
