Adjusting The Fan A6820 And Sf65/Sf85 And Xf90; Single Side Blinds (Optional) - Hardi NEPTUN Series Instruction Book

Adjusting the fan A6820 and SF65/SF85 and XF90

The angle of the fan blades can be adjusted to 4 positions. The factory
setting is pos. 3 (40º). Decreasing the angle of the blades (minimum
angle, pos. 1 (30º)), reduces the air fl ow and power consumption.
Increasing the angle (maximum angle, pos. 4 (45º)), will increase the air
fl ow and power consumption. It allows the mist blower to be adapted
to the diff erent spray jobs and tractor sizes.
To change the angle of the fan blades you should follow these steps::
1. Loosen the Allen screws without taking them out completely.
2. Loosen the Allen screws whilst holding the nut at the back of the
fan.
3. With both hands on opposite blades, turn them to the desired
position between 1 and 4. All the blades should turn at the same
time.
4. Finally, check that all the blades are in the correct position.
5. Tighten all the screws.
IMPORTANT The fan must be calibrated correctly after changing
the pitch setting.
For technical details ask your dealer and factory.

Single side blinds (Optional)

The air stream can be blocked to one side to prevent spray drift towards
sensitive areas.
This is used when one section valve is shut during spraying along
orchard edges, streams, open waters or other sensitive areas where
spray drift must be kept away.
Loosen the nuts, slide the blind over the air outlet and tighten the nuts
again.
ATTENTION! Only slide the blind of one side at the time. Never
close both sides at the same time!
