PRE-OPERATION
11. Cycle through all 3 taps for Left and Right Spray
Rings plus the Agitator. All are shown below in
the ON position. Check that all functions are
operating correctly.
12. With all taps on, set the PTO speed to the intended
operational speed (usually between 450 ~ 540 rpm)
and adjust (red knob) the spray pressure to the intended
spray pressure.
Repeat the process while drawing fresh water from the
Flushing tank.
Note this test should not be done with a full main tank as it
can overflow the main tank.
After shutdown, check & clean the filter (refer to page 18).
CONFIRMING FAN FUNCTIONALITY
The maximum allowed PTO speed is 540 rpm
DO NOT engage or disengage the fan’s gearbox
whilst the PTO is engaged.
Always disengage the PTO before changing gear
(Neutral or Run).
1. Check that nothing is loose or damaged
2. Check all fittings are tight
3. Check the gearbox oil level before starting
4. Check PTO and Fan guards are in place.
5. Engage the fan gearbox to “RUN”.
NOTE
It’s useful to find the lowest rpm at which
the PTO can operated and still deliver the
chosen spray volume and pressure. Note
that below this point there will not be any
bypass flow back to the tank to aid with
tank agitation. If the PTO speed is
significantly above the minimum required
there will be a risk of tank chemical
foaming from excessive agitation.

NOTE
Whenever the fan is being run “dry”, it’s best to
have fresh water running through the pump –
with the pressure controller in the OFF position
allowing water to bypass back to the tank.
