Why is it impossible to introduce drill chuck or morse taper into my Optimum Drill?

It might be impossible to introduce the drill chuck or morse taper because there is dirt, grease, or oil on the inner conical surface of the drill chuck or on the conical surface of the drill spindle. Clean surfaces well and keep surfaces fat free.
