How to fix a kango jackhammer 950x stopped working a little smoke came out, replaced brushes and still not working for one had come off the wire switched on still did not work?

If your Xtreme Power US 2200W jackhammer is not working and not making any sound, there are a few troubleshooting steps you can try before determining if it is beyond repair:

1. Check the power source: Ensure that the jackhammer is properly connected to a power outlet and that the outlet is functioning correctly. You can test the outlet with another device to confirm if it's supplying power.
2. Inspect the power cord: Examine the power cord for any visible signs of damage, such as cuts, fraying, or exposed wires. If you notice any issues, it's important to replace the power cord or have it repaired by a professional.
3. Verify the power switch: Make sure the power switch on the jackhammer is in the "On" position. Sometimes, the switch may get stuck or be in an intermediate position, preventing the tool from turning on.
4. Check the circuit breaker: If the jackhammer is plugged into an electrical circuit with a circuit breaker, verify that the breaker hasn't tripped. If it has, reset the breaker and try again.
5. Examine the carbon brushes: Jackhammers typically have carbon brushes that make contact with the motor to enable operation. Over time, these brushes can wear out and require replacement. Open the jackhammer and inspect the carbon brushes for wear or damage. If they appear worn down or damaged, they may need to be replaced.
6. Seek professional assistance: If none of the above steps resolve the issue, it's recommended to seek assistance from a qualified technician or contact Xtreme

Unfortunately, you won't find them - Kango was a great hammer, but the company has been gone for many years and there are no parts available.
I would find a local repair shop that may have a different brand brush that is the same or bigger dimensions - by using a piece of 220 grit sandpaper on a hard, flat surface - you can sand them down to the proper size.
It will get you out of a bind

A Milwaukee powertool dealer

Its the ask if its a MILWAUKEE kango 900K yes but if its a KANGO 900K the metal red or metal blue demolitionhammers its difficult to find but the cause of the broken con rod when the machine is not good air tight it can have has burned o-rings and more also the battle cilinder can be torned and piston pin not smooth enough and ,more parts of the original English KANGO are not simply deliverable anymore, but for the American milwaukee red 900k its not a problem

Could be brushes, switch or wiring. Use a meter to see.

Check:

• frayed wires where it enters Kango
• is power at switch
• Power thru the switch
• Frayed wires at cord plug
• And finally - Brushes

These are the EASY checks, if none of the above, take it to your local service center.
Good Luck

Milwaukee K900K or the English Kango 900K Blue old or Red some younger handle it differs very much English Kango was using a thick brown grease in 2 chrome colored plastic bags . the Milwaukee K900K has a lubrication grease also not oil but be aware of the operating hours i f you have a K900K model from Brand Milwaukee tools replace also a service kit and the bearings on the armature is important also Its neccesary to protect you from damage
if you have a English Kango its hard and expensive to get a spare parts and most times the tools are worn in the front of the chisel stroke bolds do not get right close and the piston pins are worn it was a good tool about 20 years ago i have serviced much of them . but the first thing thats important that its air-tight in front of the chisel and everywhere thats having a mechanic/pneumatic duty



Milwaukee Services and fill k900k with (IMPORTANT) the right number

it sounds like it needs service,service is taking lower unit apart cleaning and regrease with special kango grease, if unit was serviced recently or not used much, grease could be real old and dry,sometimes you have to warm up unit before they start hitting correctly,,also if used a lot could be dirt build up,inside bit holder.remove bit holder clean out dirt regrease with heavy bearing grease,just grease the lower part,not very much grease is needed

Milwaukee now owns Kango, unfortunately I believe the 950sv is the old style. Parts are no longer avail. I have about 20 of the breakers. It is really too bad, they were great machines.
