Bosch SDS-plus BULLDOG Xtreme Rotary Hammer 11255VSR - Answered Questions & Fixed issues
Chisel bit will not lock
Are you sure you are locking it in right? The STS locking mechanism on most of these tools is sometimes hard to do, you have to sometimes really push hard while turning it until you hear an audible "click" to know it is seated.
Runs but doesnt engage rotary or hamer. the
there is a selector knob on the side that controls the tool functions for drill only/hammer with drill/ and hammer only. make sure it is in the proper setting. If it still doesn't rotate then you have a gear or a broken selector. If no hammer then you have worn o rings or a stuck ram. try the selector first and if still no change please be more specific if no hammer at all, or no rotation even when selector moved.
Hammer action power there but weak
It is hard to understand what you are asking, however I have found that with the SDS drills one does NOT want to crowd them but just let the tool work with light pressure...
How do you remove selector knob on bosch 11255vsr
Rotate the selector to the 4 to 5 oclock position, or the 7-8 oclock postion, push the red button in all the way with a screw driver and pull the knob out. Certain model hammers you have to rotate to a slightly different position to remove the selector, you will have to try one, if it doesn't work try the other.
How do I insert a
There is a collar that you have to pull back, it is kind of big. Be sure to rotate the bit, as you install it, sometimes tricky to engauge the last tiny 1/2 inch or so. The tool will be retained, but not engauged.
Bit will not come out of the end of the hammer
If the chuck will loosen and the bit still won't come out try tapping
firmly on the tip of the bit with a scrap of wood while the chuck is
loose. There are a couple ball bearings in the chuck that stick
sometimes.
