Agitation Before Re-Starting Spraying; Operating The Control Unit While Spraying - Hardi COMMANDER TWIN FORCE Series Instruction Book

5 - Operation
ATTENTION! If there is not time enough to fill all chemicals into the ChemFiller before main tank is full, then it is
possible to slow down filling proces by partly closing the External Filling Device valve.
DANGER! Do not press lever unless the multi-hole nozzle is covered by a container to avoid spray liquid hitting the
operator.

Agitation before re-starting spraying

If a spraying job has been interrupted for a while, severe sedimenta-
tion can occur depending on chemicals being used. When re-star-
ting spray job it might be necessary to agitate sedimented material
first.
1. Turn handle at the suction SmartValve towards "Suction from main
tank". Turn pressure SmartValve towards "Pressure emptying" or not
used function and turn the Agitation valve towards "Agitation". Other
valves closed.
2. Engage the pump and set P.T.O. speed at 540 r/min or 1000 r/min
(depending on pump model).
3. Agitation has started and should be continued for at least 10
minutes.
4. Revival of the spraying can begin. Turn pressure SmartValve
towards "Spraying" and start spraying..

Operating the control unit while spraying

The switches on the spray control box controls the following
functions:
1. Power ON/OFF
2. Spray pressure regulation
3. Main valve ON/OFF
4. End nozzle (Left/OFF/Right)
5. Foam marker blob interval
6. Foam marker (Left/OFF/Right)
7. Section valves
8. Optional function
In order to close the entire boom, switch ON/OFF (3) to OFF posi-
tion. This returns the pump output to the tank through the return
system. The diaphragm Non-drip valves ensure instantaneous clo-
sing of all nozzles.
In order to close one or more sections of the boom, switch the rele-
vant distribution valve (9) to off position. The pressure equalisation
ensures that the pressure does not rise in the sections which are to
remain open.
On the sprayer the suction SmartValve should be turned toward
"Suction from Main tank" and pressure SmartValve should be turned
toward "Spraying". Turn the agitation valve to "Agitation" if necessary.
