Preva Tubehead Removal Instructions
Overview
Tubeheads are shipped with the yoke cable assembly mounted to the tubehead.
This guide provides instructions for the installation technician on how to remove
the original head, install the replacement tubehead, and how to calibrate the
replacement tubehead.
Do not remove the tubehead until the articulating arm
assembly has been secured with the provided cable tie and
foam insert. The spring tension is adjusted to account for the
weight of the tubehead. If it is not secured, the articulating
arm will spring open and can cause serious injury.
