Milwaukee demolition hammer when you pull the trigger it starts full rpm then with trigger still on slows right down anyone know what this might be thanks

Unfortunately, Kango is gone - there are very few parts available and most of the parts still around will only be found in Europe now. It really is too bad because they were a great hammer.

Mine stopped and I took it apart and found a badly worn piston gasket. I can't however find a new gasket. Anyone know where to get parts for the sky687 hammer drill then let me know. [email protected]

Hi Vicki
Is it the old all silver one or the new one with the red motor housing?

Variable speed control module has failed, however you can still use the tool. Hammering action will improve with a good cleaning of internal parts and apply new grease. Hammering action is caused by air/vacuum cushion between drive piston and driven piston which inturn hits a third piston that actually impacts the bit. If third piston is worn, chipped and lodged with debris, there will be light hammering action. After use, store the hammer with the nose pointing down so that the driven piston will slide to end of cylinder and ready for next use.

did you have the trigger in the locked position, some tools have a safety that you need to release the trigger after plugging back in to reset the switch. try that first.

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

rockworth powertask demo hammer needs new trigger how do i get parts

demolition hammers require hydraulic oil in most cases.
Any good tool shop should have hydraulic oil to suit.

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.
