-Before installing the drill bit, open the chuck cross-hole first. Sometimes the chuck core is received.
In the tightly closed state, the drill bit cannot be inserted into the cross hole, just loosen the copper nut.
-Insert the drill bit into the cross-hole of the sandwich core and then use the 7-shaped wrench to insert the hand into the small hole at the bottom of the chuck to fix the chuck.
