The specifications refer to environmental conditions with a temperature between -10° +50°C (14°C -122°F). The working temperature limit of the box is 90°C (200°F) established to prevent the ageing of the seals and guarantee a sufficient viscosity of the oil. The heat makes the air in the box expand and therefore increases the pressure inside. The correct use of the oil seals is guaranteed up to an internal pressure of 0.5 bar. Boxes designed to be used for particularly heavy duty work are equipped with a breather cap that can be fitted on any cast iron box on request. O500 Nylon impeller with sinterized expansion clutch. unigreen 17 5.3 DISTRIBUTOR ACCESSORIES POLIPO SPALLIERA SUPER SPALLIERA Various configurations of accessories or distributors are fitted to the outlet of the fans. At present these are: Polipo - Super Spalliera - RV GDC WARNING: for all adjustments, always observe the safety indications in the chapters relevant to maintenance and repair of this manual, as well as paragraph 2.3.1 relevant to the use of chemical products. 5.3.1 POLIPO FOR ESPALIER Tangential flow accessory that brings the diffusers closer to the walls to treat, for targeted and localised interventions. The vertical construction puts the distributors parallel with the walls of the vegetation, guaranteeing a uniform treatment with limited absorption. Versions with 4 or 5 distributors per side are available to choose from on the basis of the height of the row. The height of the arms can be adjusted by hand and the distributors can be inclined to direct the chemical product in the best way for the configuration of the vegetation. All the adjustments are made by hand using knobs and screws. When treating particularly wide rows (up to 4 m) OPTIONAL extendable arms are available. The "POLIPO" accessory is used with STD version fans. 5.3.2 SUPER SPALLIERA FOR ESPALIER With this accessory you can treat particular espaliers with thick vegetation. It is especially indicated where you need to pass beyond the rows, using a lot of air and power. The variable diffusers let you direct the product in relation to the requirements of the vegetation. All of the adjustments are done by hand using the knobs and screws. The SUPER SPALLIERA accessory is used with XP fans. RV per GDC 5.3.3 RV BOOM FOR GDC This boom has lateral diffusers (variable and moveable) and two top arms with hydraulic or manual adjustment, so the jets can be directed onto the vegetation to be treated. In the bottom part there are two adjustable, telescopic distributors for GDC treatment. The height of the structure can be adjusted by hand for different types of vegetation. The RV-GDC accessory is used with XP fans. 18 unigreen 5.4 HYDRAULICS The RV, VL, VLX, FXF and FXL model distributor accessories have hydraulics that can be controlled by the operator directly from the seat in the cab. Check that no one and nothing is in the area where the booms will open; particular attention should be paid to the presence of any electric power lines. The hydraulic plant can be fed from the hydraulic pump of the tractor. The hydraulics can be controlled using the lever of the tractor (RV and VL) or a hydraulic distributor with mechanical or electro-hydraulic command with switches in the cabin (VLX, FXF and FXL). - All of the controls on both versions are sustained action controls and each lever or switch has a pictogram of the relevant operation it controls. WARNING: with hydraulic booms, don’t stand in the range of action of the machine. Pay attention to the integrity and efficiency of the hydraulic components and in particular to the pipes to prevent the risk of bursting. Do a full check on the pipes and components at least once a year, we recommend replacing hydraulic pipes every 3-4 years. 5.4.1 OIL FEED FROM TRACTOR (for hydraulic systems) Connect the delivery and discharge quick-fit coupling to the respective connections, respecting the direction of flow. The distributor inlet pipe is connected to the aluminium flow separator valve next to the distributor. The flow separator must be adjusted correctly so it sends less than 4-5 L/1° to the distributor. To prevent the cylinders moving at a dangerous speed, adjust the relevant chokes near the cylinders. If the registration ringnuts aren’t visible then fixed chokes are fitted. The chokes are fitted on the discharge line of the movement to slow. Any impurities in the oil could block the chokes and as a consequence block the cylinder; remove the dirt if necessary. The maximum pressure valves of the distributors are regulated to a pressure of around 150 bar. To prevent the excessive heating of the oil we recommend supplying the distributor of the sprayer only when the cylinders are being used. We recommend having qualified personnel do any adjustments. Pay attention to the integrity and efficiency of the hydraulic components and in particular to the pipes to prevent the risk of bursting. Do a full check on the pipes and components at least ...
