How to Feed Water
Caution
When feeding water, be sure to apply the
parking brake, latch the tires, and put the HST
lever in the “N” position.
(1) Adding the Required Amount of Water in the
Reagent Tank
* If no water supply facility is available, a jet pump
(optional (sold separately)) would be useful.
(2) How to Operate the Jet Pump
[1] Prime around 20 L of water into the reagent tank.
[2] Connect the pipe from the jet pump to the cock
connected to the spray pump, and open the cock.
[3] Throw the strainer end of the jet pump into the
water source and insert the opposite end to the
water inlet of the reagent tank.
[4] Close the spray cock fully.
[5] Put the throttle lever to the idling position and press
the spray pump switch.
[6] Pull the throttle lever and adjust the engine speed to
a medium level.
[7] Operate the pressure adjustment dialto adjust the
spray pressure to between 2 and 2.5 MPa.
[8] When the required amount for spraying is reached,
close the cock of the jet pump.
[9] Return the throttle lever to the idling position and
press the spray pump switch to stop the spray
pump, and then remove the jet pump.
Warning
Never feed water directly from a drinking water
source or any lake or pond used for aquatic
farming.
Reagent Preparation and Handling
(1) Reagent Preparation
[1] Before preparing the reagent, check the spray
condition with water.
(Refer to P. 30)
[2] Prepare only the required amount using a dedicated
container.
[3] Dissolve the water-dispersible powder well with a
small amount of water and then add the diluted
powder.
[4]
Confirm that the spray cock is in the “Closed”
position and liquid feed valve is “Open,” and then
press the spray pump switch. The spray pump will
actuate and agitation will start in the reagent tank at
the same time.
[5] Put the reagent in the reagent tank by making sure
it does not spill out of the tank, and agitate the
reagent fully.
Caution
The spray pump and jet agitation are
interlocked. Once the spray pump stops, jet
agitation also stops. Do not stop the spray
pump while reagent remains in the tank,
because chemical damage may occur.
Caution
Carefully read the operation manual of the
applicable reagent and use the reagent
correctly.
Be sure to use the water filter net and when the
spraying is over, clean the net together with the
water absorption strainer.
