      Pulsing K5.50

      Hi, Am having problems with my K5.50 it's constantly pulsing, when not in use, and I have also noticed it's slightly down on power. I have been told it could be the control head, but after removing this, I can't see any evidence of it leaking.... Help what do you think? Thanks

      • I had a cracked control head body and cracked Vario lance nozzle in my K4.99M, and replacing these parts cured the pulsing and low pressure. I believe that these problems were caused by freezing damage. By rog3141 - Basingstoke - 19 June 2010
