It is very hard to find parts for tools made in China. There are many look-alikes all with different names. They could, however share parts. If you look on ebay searching "sds roto hammer" you will see many hammers that look similar, different colors. Take a look at the hammer listed below. It is a harbor freight tool. The parts may work. If you have harbor freight in your city, take a look (or on ebay). To order parts for harbor freight tools, look at manual for tool selected, there will be an 800 number to call.

Hi there.
You can get Owner's Manual of your Roto Fryer at the Kitchen Appliances page of http://www.delonghi.com
Regards.

the grease is for the chuck as SDS chucks often seize up

If you are getting leakage out the chuck end, the shaft seal needs replaced. You can get it done at a Bosch service center or get the seal and replace it yourself. Don't wait to long there is only a limited amount of lubricant in the tool.

solved by own initiative. no more emails required
