7-2-2 Cleaning the Chuck
In order to maintain the precision of the chuck, remove it regularly for cleaning with
an ultrasonic cleaner, etc. It is recommended that you clean it at least once a week
to ensure the product can be used safely.
CAUTION
Neglecting to clean the chuck for a long time is very dangerous because wax, gypsum, etc., will accumulate in the chuck,
causing the bur to be insecure and causing runout.
