yovko Posted February 27 Report Share Posted February 27 Hi guys i i’ve got bosch gsh 16-30 that doesn't hammer properly i mean the motor runs but the tool just vibrates slightly and thats all doesnt hit strong as it should , ( feels like the striker locks or something) i’ve inspected everything possible and no luck , changed the o rings ( piston and striker) cleaned the old grease and lubricated with new one , if you press the tool against the concrete and press the switch it will hammer properly once depress and the revs of the motor increased it will just vibrate very weak and no hammering at all . I am running out of options what could it be , no excessively worn parts upon inspection ? Its a mystery . Any help will be much appreciated .
