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

5 - Operation

Adjusting the fan A6820 and SF65/SF85

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 flow and power
consumption. Increasing the angle (maximum angle, pos. 4 (45º)),
will increase the air flow and power consumption. It allows the mist
blower to be adapted to the different 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.
μ
ATTENTION! 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.
μ
ATTENTION! Only slide the blind of one side at the time. Never
close both sides at the same time!
