I bought a Karcher 3.68M electric pressure washer. It has a detergent
tank that attaches to the unit. After assembling the unit and reading
the instruction manual, I cannot seem to figure out how to actually
attach the detergent tank to the unit. The Karcher website talks
about attaching the tube from the tank into the siphon injector, but
where is the siphon injector on this unit? I can't seem to figure it
Thanks for your help.
