Unloader valve
Pump pressure is reduced by
means of an "unloader valve"
which returns water to the inlet
side of the pump at a minimum
pressure. The point at which this
occurs is set and sealed at the
factory and must not be adjusted.
Chapter 5 describes the use of
the high-pressure cleaner for
various cleaning jobs.
Always use the cleaner as de-
scribed in these operating in-
structions. Any other use may
damage the cleaner or the sur-
face to be cleaned or may result
in severe injury to persons.
