Chuck Installation
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 chuck is firmly seated against the face of the spindle all the way
To install the chuck:
1.DISCONNECT LATHE FROM POWER!
2.Use an appropriate lifting, support, or protective device to protect the ways and support the chuck during the installation process.
3.Clean and lightly oil the camlock studs, then thoroughly clean the mating surfaces of the spindle and chuck.
4.Install the chuck by inserting the camlock studs straight into the 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.
