689060 relief valve, operating instruction
When starting the pump and during chemical refill and mix
operation keep the lever handle
9
in released position. When
fully released the system circulates pumped material back to
the tank with minimal restriction, easing load on the pump.
Setting working pressure:
When operating the pump the suction valve must be open.
When setting system pressure there must be liquid in the tank.
1 Set the working pressure with your spray nozzles closed:
you should not be spraying.
2 With the lever handle
9
engaged and the pump shaft turn-
ing at operating speed, loosen the jam nut
2
and adjust the
pressure screw
1
. Turn the handle on the pressure screw to
set working pressure: clockwise to increase pressure; coun-
terclockwise to reduce.
3 If using a gun or boom applicator, begin spraying and
watch the pressure gauge: adjust pressure as needed.
4 When you have reached your desired pressure, tighten the
jam nut
2
against the fork
3
to lock the setting.
