PRE-OPERATION
CONFIRMING SPRAYER FUNCTIONALITY
After the sprayer is hooked up correctly to the tractor, it’s
advised that a freshwater test be done to check for leaks
and to familiarise the operator(s) with the sprayer.
These checks have been conducted in the factory prior to
shipping, however, there is a chance that transit could have
loosened some fittings.
Running the machine with fresh water is a good safe way
to calibrate, learn about the sprayer and set the sprayer to
maximise results in the field.
1. Check that nothing is loose or damaged
2. Check all fittings are tight
3. Check pump oil levels (refer to pump manual for more
detail)
4. Check PTO and fan guards are in place
5. Add some fresh water to all the tanks, with at least 100
litres in the main tank
6. Select the water source from MAIN tank.
7. Make sure the Fan (gearbox) is in the neutral position
(refer to page 13 & 15).
8. Ensure all spray function controls are in the off position
and with a low-pressure setting. Whilst the pressure
has been set at the factory (normally 5 ~ 6 turns open),
there is no guarantee it hasn’t been altered. To be safe,
turn the pressure knob out ½ of a turn.
9. Power up the tractor (brakes on) and engage the PTO -
no need for full power at this stage, set to say 350rpm.
At this stage the pump will be drawing from the main tank
and bypassing the pressure regulator / controller straight
back to the tank via the return hose
(yellow arrow)
.
10. To activate the spray controls, turn on the pressure
manifold (main side lever down).
Adjust the red knob to change the pressure.
The photo shows 8 bar which is ideal for start-up
testing. Maximum = 20 bar.
