Hi: I was trying to download the manual for Karcher pressure washer Model 670M but was unable to. Is there any possibility you could send it to me via e-mail (I do not need the French version) at marilynrneilson@shaw.ca? In addition, could you please provide some clues as to why the machine has lost its pressure when it used to be good initially. Thanks in advance, Marilyn Neilson, Edmonton, Alberta
