Instructions

A set of replacement jaws is available as P/N 1177. Should
repair become necessary, please return your chuck to the
factory so that we may replace the jaws and check the
alignment of the chuck before returning it to you. In the
case of a damaged chuck body, replacement of the entire
chuck is usually more economical than attempting repairs.
ER-16 Chucks
Introduced in early 2014, the P/N 1078 3.1" 4-jaw self-
centering chuck is now offered with a 22 x 1.5 mm thread
for use on the optional ER-16 spindle nose for the headstock.
It is used in the same way as a standard chuck but now
offers those who opt for the ER-16 collet option a way to
use a Sherline chuck on their lathe.
Lubrication and Maintenance
Clean chips from the jaw slots with a brush and add
lubrication to keep the chuck operating smoothly. To
prevent rust, keep the surfaces of the chuck lightly oiled.
If possible, store wrapped in the waxed paper it came in.
Thank you,
Sherline Products Inc.
CAUTION!
• These chucks were not designed for use on high
speed spindles operating at speeds above 3000 RPM.
• IMPORTANT! Do not turn the lathe spindle on
unless the chuck jaws are tightened. Acceleration
of the spindle can cause the scroll to open the chuck
jaws if they are not tightened!
