hello guys ,if anybody knows how to change the chuck i will be so grateful.
i pulled apart the motor from the nose but i can not see how to open the nose it seems sealed
I got a key but i am afraid to twist on the chuck itself to avoid breaking it pleas lead me trough this
Thank you

It unscrews right from the top, no need to take apart. Use the side of the wrench that came with it marked 5.1and turn counterclockwise.

It should have come with two wrenches. Keep the nose on. On the sides of the nose are two flat spots where wrench fits on to keep it from turning. When you have this wrench on you then use the wrench that fits the chuck and like Toast said turn it counter clockwise. FYI when replacing a chuck put a small dab of grease on the threads, it makes it easier to change out next time.

No. I have learned though to put some grease on the threads of the chuck, it makes changing out easier next time. They recommend you taking the chuck out and clean on occasion. I have run them for years they are a work horse.

Very often chuck can get seized and stuck in handpiece when you force them out.If you feel tension just go back and forth and keep going till get out.

What if I can’t find the key, is there anything else I can use?
