Replacing the replacement chuck head – reserving functionality and safety
After a long period of use, it is possible that the replacement chuck head will no longer hold an inserted instrument adequately, resulting in the instrument no longer rotating when the handpiece motor is switched on, or the instrument no longer being able to be inserted into the chuck. This deterioration in the function of the replacement chuck head is normal and is not a reason for complaint.
Note
Contaminated dust particles may be released when replacing the replacement chuck head. Therefore, wear suitable mouth and nose protection. Disinfect the workplace and the drill with a suitable surface disinfectant.
