Great videos, you are a great tool repair guy. Keep up the good work.
Gracias
i will just get a new one mine is more than 20 years old . just hope the new one is half as good as the old one was.
hi like your videos very helpfull, question why have you not made a video on how to dismantle a bosch GBH 4-32 DFR my armature is burnt out, not sure how to remove it
thanks 😊 🫂 🙏 😊
Thanks for the videos !
What grease or oil would you recommend for GBH 4-32 DFR ?
Just what I needed, very well done. What is that screwdriver/ratchet quick disconnect tool you are using?
Appears to be a Wera Zyklops, something else unexpected that I need just because it's so cool.
I gave you your 100th like! it would be very useful if you could state the Torx and other bit sizes eg.PZ2 required to dismantle. Thanks!
Thanks for this video !! It helped me to disassembly my hammer.
What part number is the part you are showing in 9 minute 21 seconds ? I can't find it in any catalog or repair manual. In my hammer, this part is totally destroyed :( and full "head" is expensive. best regards.
why would my GBH 4 DFE not work on hammer only , works ok on drill and drill hammer!!
I'm a little disappointed in mine. It's about 5 years old, but only used a few times, now the drill works but 0 hammer effect. And buying Bosch, I figured I'd get a few years of heavy use. Not a few years of hardly any use. Spend almost 400 bucks and get a few uses out of it.
What's this compressed air I'm reading about in some repairs I've watched? Says, o ring is bad and won't compress air any more. These are rotory hammer's, right?
Thanks ma friend.
