Installation Notes

Installation is typically performed by a machinist or mill technician. Before replacing or installing a drawbar, power down the machine and ensure the spindle is fully stopped. Use a wrench on the hex section to tighten the drawbar to the tool holder without over-torquing, which can damage spindle threads. Consult the machine manufacturer's service documentation for any machine-specific procedures.
