Hi all!

I try to remove keyless chuck of my Bosch PSB 600RE drill. Manual says
that I have to put Allen key into chuck, hit its longer arm when spindle
locked but with no success. I've found that chuck is usualy blocked with
screw inside (nothing about it in my manual) to prevent self-unscrew from
spindle during reverse operation but all I can see inside is small round
hole at the bottom. Please help me, I don't want to destroy something
using too much force. Have anyone did it?

Looking down into the hole of the chuck you should be loosening by turning
the chuck counter clockwise. Sometimes things will loosen easier if you
try to tighten just a bit before loosening.
As for as the lock screw, what you are looking for that is common on
reversible drills. If yours is not reversible there probably is no lock
screw.
