Faulty bosch hammer drill

BOSCH GBH 18V LI TYPE 3 611 J04 300 Service Manual free download... wait until processing is having changed to Get Manual ! to know the download link

Take a little screwdriver under the knop and jump him out BUT be carefull there is a little metal pin inside the knob that can be loose and easy lost .
And important Jump out the knop (BEFORE) you have removed the 4 screws of the black house.

The collar of the chuck should pull back releasing it. You will have to pull back the chuck and pull the bit at the same time.

see the video and fix it. God bless you

Check that the ramped discs and the selector lever for the hammer action are assembled correctly. The lever should push the chuck shaft clear of the hammer action discs or release the shaft so that it can move inwards to allow the ramps to ride up each other.

Sounds like brushes need to be replaced

hi

check the cord and the switch to have continuity,the wires,the brushes,the rotor and stator.

Go to Boschtools.com and type in your number or go to tools and rotary hammers and highlight your hammer, it will take you to another page and then you can look at a breakdown which is very specific on the direction and placement of the selector. The shift fork must be in the forward position and you can eyeball it with the post on the selector after you have it in position to lock it in. Remember you have to depress the plunger on the selector to reinstall it. Let me know if you still are having problems.

Check the cord...sometimes if the brushes are not seated well or if there is a cut in the cord you will run into that problem....If it is not that then possibly you just have a faulty drill
