WARNING: the indications to follow for using chemical products are indicated in paragraph 2.2.1. 4.12.2PREMIXER ON COVER (OPTIONAL): Open the cover and pour all of the chemical powder into the filter, close the cover and open the supply tap until all of the powder has dissolved. 4.12.2PREMIXER ON COVER (OPTIONAL): Open the cover and pour all of the chemical powder into the filter, close the cover and open the supply tap until all of the powder has dissolved. FIG. 15 4.12.4COVER WASHER FOR CHEMICAL CONTAINERS The washer for chemical containers (FIG.15) is installed as standard in the hatch on the entire Airdrop-MFC range. To wash the container, proceed as follows: -Lift the cover of the tank -Open auxiliary tap (D) of the pressure regulator (see paragraph 4.8.1) supplying it with a pressure of under 8 bar - Introduce the tin into the hopper, inserting the washing pipe into the tin. -Press the tin onto the pipe until it has been washed clean. -At the end of the operations close the tap (D) of the pressure regulator again.

Dirty equipment is very dangerous for people and in particular for children. Discharging the residues of washing in the environment without taking precautions is forbidden as this pollutes water courses. Distribute the residues on the field or the crops where they won’t cause any damage. WARNING: the indications to follow for using chemical products are indicated in paragraph 2.2.1. 4.13.1CIRCUIT WASHER AND TANK WASHER Some machine models are fitted with a circuit washer tank (FIG.17). This tank must be filled with clean water and used to rinse the entire circuit including the suction, delivery, pump, pressure regulator, jets and nozzles. Thanks to the practical rotary nozzle it also rinses the inside surfaces of the tank. NB: To completely clean the tank and the pipes of any residues of the various active principles, we recommend adding 2kg of soda to the washing liquid for every 100 L of water. At the end of the treatment, wash the circuit and the tank. a) Stop the diaphragm pump disengaging the power-takeoff. b) Check you have filled the circuit washer tank (C). c) Make sure the main control of the pressure regulator is OFF and that all the boom sectors are closed. d) Turn suction deviator A to the circuit washer position (H2O). e) Start the diaphragm pump by engaging the power-takeoff. f) Increase the engine speed until all of the liquid in circuit washer tank C has been sucked up. g) Turn the diaphragm pump off and turn deviator A to the work position (TANK). h) Turn the main control to ON, so there is pressure in the circuit. i) Start the diaphragm pump again and use the tank washing tap on the regulator (or on pump P) that supplies jet B. j) After a few minutes you can close the tank washing tap k) Distribute the washing residues over a portion of the field where it won’t cause damage. l) After you have finished washing, stop the diaphragm pump. NB: at the end of the washing cycle, if there is the risk of frost, pour roughly 500 grams of normal antifreeze for auto vehicles into the tank. A B C F P WARNING: using the taps on the pump or in any case on the front of the machine puts the operator near the cardan shaft. Despite the presence of protections at CE rule, it is compulsory to switch off the engine and to take the key off. 16 unigreen BLOWER GROUP All the mistblowers have a high speed fan rotor.You must take great care and beware of the effects that this can provoke: such as the aspiration and projection of foreign bodies which, although of a small size, can be very dangerous especially for the eyes and face. 5.1 MULTIPLIER - FAN UNIT The Airdrop range is fitted with two versions of a O500 centrifugal fan: STD (max absorption 30 HP) and XP (max 50 HP). The transmission of the drive from the pump to the fan is done through a multiplier with one or two gears, plus neutral. Normally the rotation speed of the fan is 3240 RPM in first gear and 3620 RPM in second in the 2-speed multiplier (multiplied ratios 1:6 - 1:6.7) with the power takeoff running at 540 RPM. You can change from one gear to the next with the lever on the multiplier, made accessible through the opening on the side in the rear left part of the machine or at a distance on the right side. The lever has 2 or 3 positions depending on the number of gears and the central position is neutral (to use only the pump without the fan). WARNING: the gear change lever must only be used with the power-takeoff disengaged and the fan stopped. If it is difficult to engage, turn the cardan shaft slightly by hand to find the right position of the lever (make sure the tractor is turned off). For the maintenance of the multiplier (see point "Multiplier Lubrication" 5.5 CLUTCH Fans have a centr...
