I have a bosch 11264EVS hammer drill that just stopped working. I checked the brushes and have continuity to the rotor. Is there somethingelse I need to check/replace before I hunt sown a service center?

Faulty switch or worn / badly seated carbon brushes are the most likely reason.

• If look at brushholder unmount it and make clean look if the brushes are go good to each other most causes on this BOSCH tools is that the brushes 70% are hanging on dirth in the brush holder (brushplate) 16 first problem second true problem are the 2 suppression coils (adapter module 817 ) on the electric field. and also parts pos 19 left right switch contacts for the brushes can sometimes on ofthem be broken.

www.powertools-aftersalesservice.com this site allows you to input the model number in the trade name box or if you look on your tool you will see a 10 character code quite often starting with a '0' enter this number in the part number box. This will then display your exact model variation, voltage etc. (the former search will bring up a list of possible models, voltages and countries). From the parts break down you will see there is a clutch fitted. Testing of clutches is not easy and many makes can not be adjusted. I have seen on SDS drills the guide lugs in the tool holder have sheared/Worn away and the drill bit can be turned freely if the steel balls are removed from the chuck. On a max there are more lugs but I don't suppose it is unheard of these al wearing away. If it is a clutch problem you will hear the drive slipping. If it is the latter the drill will sound normal. All that said It could even be gear teeth that have broken and so not meshing in the rotation mode. Only stripping the tool will identify the fault.

No, if it got hot and won't work you have another problem you can start troubleshooting by looking at the cord and continue thru to the brushes.

Take it back as it is still under warranty. If there was anything you could do other than letting it cool down it would be in the instructions.( which you have since it is brand new.)

hi

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

regards savumihai71

Professionnal repair sure will go around 100$. The rotor is broke, figure if it worth it...

These tear the brushes out. You can not use them for hammering. It is a design problem.

Replace the brushes and use only for straight drilling.

Check the Cable between the plug and the switch for continuity using the ohmeter or continuity tester part of a cheap multimeter. Place one lead on each of the plug contacts in turn, and the other on the other end of that wire. If this is okay, check the switch for continuity by placing each lead of your tester on the in and out contacts and pressing the trigger. If still no joy, check the brushes. If still no joy, check the motor windings for continuity.
