twist fast coupler and tighten securely. Fasten wand and gun
together and connect gun/wand to high pressure hose.
Tighten all connections and replace worn
parts before starting the machine. Sudden
release of high pressure streams may result
if connections detach during use. This can
cause serious injury. Never disconnect any
part of the unit while the machine is running
or before relieving system pressure, it is
dangerous. Seek medical attention if an
injury ever occurs.
