My Jackhammer starts for a good 5 seconds then stops but continues to make a humming sound. Can you tell me what could be wrong
Sound like a bearing problem the armature (if electric) then it could also then touches the metal of the electric field. so the armature is not in balance in the middle or the field is become loose by the vibration he then drags on the field and then there is no induction anymore. it adheres magnetically with a good humming , it is not the capacitor because there is a start direction every time so when lubrication is necessary then allways use all rings to replace because it has no target to replace one ring and it are different rings also different materials choiced on acid temperature dissipation material on any place could be different The front may have leaking air specially on the battle bolt . The right grease for a slow rpm hammer or special oil for the high rpm hammer.

My jackhammer stoped hammering please help
if the internal motor still runs , but the chisel doesn't move , this is a sure sign that the drive pin has broken off , un plug and remove lower part of tool , there just after the motor shaft is a flat gear looking item , it has a pin sticking out of it bottom side , except I bet yours doesn't have it sticking out any longer , this pin will need replaced , this occurs when operator gets tool stuck in hole and pulls back while running it , ive changed a few in years past

Bosch sds oil the kit came with 50 ml do I need more
No its a little white plastic bottle between 45 and 50 ml comes with the consumables kit by some type of drills , for new readers of this old question be aware and pay attention if you service this kind of machines there is on the manual a great problem there is needed an extra ring of pos 102 the ring between gridring pos 47 and ring 51 sometimes it is delivered with 2 rings 102 and sometimes not but its fitted perfect its running smooth for longer time a gap must between 0.08 and 0.22 mm tolerance because 1 ring is wrong look also on the drawing of the gbh4-32dfr there is again a new and wrong positioning of this 2 rings pos 102 the 2 rings are not in that drawing between the pos 47 and 51 but there are 2 rings and in your machine 11240 you should have also 2 rings and thats correct if its only one then order a ring extra for doing a good service job

Where do I put the oil?
Most breaker hammers have no oil if they have no high speed.
But special grease with high thermal conductivity.
very important .
If there is loose grease buy a consumables kit only complete , only then it makes sense.
