samnson 14 Report post Posted June 16, 2005 Technical help – I have a Karcher pressure washer (new) Model HD3600. Operating pressure – 3600 Water volume - 4.0 GPM Engine - 13HP Honda GX390 Water source pressure at 7o PSI I can only use the green nozzle (25 deg.) using any other nozzles causes the pump to pulsate, as if the unloader not working - Adjusting the pressure controls has no effect. Any help for a newbie would be appreciated. Tanks in advance. Share this post Link to post Share on other sites

samnson 14 Report post Posted June 19, 2005 RLS, Thanks for your reply and for helping out a fellow Newbie. You hit the nail write on the head; the new rig came with a complete set of (0°, 15°, 25°, & 45°) nozzles. But I decided to save these tips except for the green nozzle and combined it with an older set I had. But due to my ignorant and lack of knowledge (Newbie) I mixed tips of different sizes. Consequently the only one worked was the green nozzle, which again came with the new rig. Thanks again SAMNSON Share this post Link to post Share on other sites
