Integrated Unloader or Bypass Valve - Pre-set by the manufacturer, for
regulating the working pressure allowing pumped fluid to circulate in the head of
the pump when the operator closes the trigger gun. The unloader valve fitted to
this pressure washer is a trapped pressure type valve which, when the trigger is
closed, maintains pressure in the high pressure line.
Trigger Gun Safety Latch - Safety stop for locking the trigger gun lever in the
closed position so it cannot be opened accidentally.
