High Pressure
Relief Valve
WARNING-If the high-pressure relief valve ever discharges water,
turn the engine off and do not use the machine. The valve will no longer
function properly. See a dealer or call Product Support at 1-800-270-
0810.
This unit is equipped with a high-pressure relief valve, which acts as a backup
safety feature. If the unloader malfunctions, the high-pressure relief valve
will open and relieve excess system pressure.
Thermal Relief
Valve
This unit is equipped with a thermal relief valve to protect the pump from
overheating. The pump continues to work in bypass mode when you are not
spraying. If high temperatures are developed during bypass mode, the
thermal relief valve will open and discharge hot water onto the ground,
protecting the pump from overheating. The thermal relief valve is located on
the unloader bypass port.
Spray Gun Safety
Latch
The spray gun is equipped with a built-in trigger safety latch to guard against
accidental trigger actuation.
