Product Overview
The Hilti DD 110-D DD-SA is a professional-grade core drilling system. This document provides critical instructions for the proper attachment and securing of the drill bit adapter to the machine spindle. Ensuring a correct connection is vital for the safe and efficient operation of the tool.
Installation and Setup
The installation process depends on the specific spindle type of your DD 110-D unit. Users must identify whether their machine uses a threaded connection or a quick-release style interface. When attaching the adapter, ensure that the threads are clean and undamaged. Use the appropriate wrenches (M26/M27 and M30) to tighten the connection securely. Do not attempt to operate the drill if the adapter is loose or improperly seated, as this can lead to equipment damage or safety hazards.
Safety and Maintenance
Always inspect the spindle and adapter threads before each use. If you notice any signs of wear, deformation, or debris, clean or replace the components immediately. Never force the connection; if the parts do not fit smoothly, verify that you are using the correct adapter for your specific model version. Regular maintenance of the connection point ensures the longevity of the drill and maintains the precision required for core drilling tasks.
