Chuck Safety &
Support Devices
Because chucks are heavy and often awkward
to hold, some kind of lifting, support, or protec-
tive device should be used during installation or
removal. The weight and size of the chuck will
determine the appropriate device to use (refer to
the following figure for examples).

during chuck installation and removal.
Dropping a chuck can result in amputation,
serious crushing injuries, or property
damage. Always use a support or protective
device to reduce this risk during installation
or removal.

To ensure accurate work, it is extremely important
to make sure the spindle nose and chuck mating
surfaces/tapers are clean. Even a small amount of
lint or debris can affect accuracy.
The chuck is properly installed when all camlocks
are tight, the spindle and chuck tapers firmly
lock together, and the back of the chuck is firmly
seated against the face of the spindle all the way
around—without any gaps.
To install chuck:
1. DISCONNECT MACHINE FROM POWER!
2. Use appropriate lifting, support, or protective
device to protect ways and support chuck
during installation process (refer to
Chuck
Safety & Support Devices).
3. Clean and lightly oil camlock studs, then thor-
oughly clean mating surfaces of spindle and
chuck.
4. Install chuck by inserting camlock studs
straight into spindle cam holes.
IMPORTANT: Avoid inserting the studs by
pivoting them in from an angle or rotating the
spindle. This can damage studs or spindle
cam holes.
