A mechanical device on the side of the reduction gear casing, allows to adjust and control the pressure of the material coming out of the pump. When the pump reaches the set value, the motor stops and starts again when the value decreases. A safety valve avoiding overpressure, guarantees the total reliability of the equipment. Frame mounted Trolley mounted Fields of application Applications materials Indoor Lacquer Outdoor Waterborne Industrial buildings Paints Emulsions Acrylic Industrial constructions Redeveloping Roofing Fillers Enamels Fixative 3 Primer English The LARIUS EXCALIBUR unit is defined “electric piston pump”. An electric piston pump is used for high pressure painting without air (from this process derives the term ”airless”). The pump is controlled by an electric motor coupled with a reduction gear. A cam shaft and a connecting rod allow to obtain the reciprocating motion necessary to the working of the “pumping group” piston. The piston movement produces a “vacuum”.

THE USE OF ANY ACCESSORIES OR TOOLING OTHER THAN THOSE RECOMMENDED IN THIS MANUAL, MAY CAUSE DAMAGE OR INJURE THE OPERATOR. THE FLUID CONTAINED IN THE FLEXIBLE HOSE CAN BE VERY DANGEROUS. HANDLE THE FLEXIBLE HOSE CAREFULLY. DO NOT PULL THE FLEXIBLE HOSE TO MOVE THE EQUIPMENT. NEVER USE A DAMAGED OR A REPAIRED FLEXIBLE HOSE. The high speed of travel of the product in the hose can create static electricity through discharges and sparks. It is suggested to earth the equipment. The pump is earthed through the earth cable of the supply. The gun is earthed through the high pressure flexible hose. All the conductors near the work area must be earthed. • Check the switch is on the "OFF" position before connecting the cable to the mains. • Never carry a plugged-in equipment. • Disconnect the equipment before storing it and before performing any maintenance operation or replacing of accessories. • Do not carry the equipment neither unplug it by pulling the electric cable. • Protect the cable from heat, oil and sharp edges. • When the tool is used outdoors, use only an extension cable suited for outdoor use and so marked. Never attempt to tamper with the calibre of instruments. • NEVER SPRAY OVER FLAMMABLE PRODUCTS OR SOLVENTS IN CLOSED PLACES. • Take care when the pumping rod is moving. Stop the machine whenever someone is within its vicinity. • NEVER USE THE TOOLING IN PRESENCE OF POTENTIALLY EXPLOSIVE GAS. • Repairs of the electrical equipment should only be carried out by skilled personnel, otherwise considerabledanger to the user may result. Always check the product is compatible with the materials composing the equipment (pump, spray gun, flexible hose and accessories) with which it can come into contact. Never use paints or solvents containing halogen hydrocarbons (as the methylene chloride). If these products come into contact with aluminium parts can provoke dangerous chemical reactions with risk of corrosion and explosion. F SETTING-UP CONNECTION OF THE FLEXIBLE HOSE TO THE GUN • Connect the high pressure flexible hose (F1) to the pump (F2) and to the gun (F3) ensuring to tighten the fittings (the use of two wrenches is suggested). NEVER use sealants on fittings’ threads. It is ADVISED to mount a high pressure manometer at the pump outlet (see on page “Accessories”) to read the product pressure. • It is recommended to use the hose provided with the standard kit (ref. 18036). NEVER use a damaged or a repaired flexible hose. IF THE PRODUCT TO BE USED IS TOXIC, AVOID INHALATION AND CONTACT BY USING PROTECTION GLOVES, GOGGLES AND PROPER FACE SHIELDS. TAKE PROPER SAFETY MEASURES FOR THE PROTECTION OF HEARING IN CASE OF WORK NEAR THE PLANT. 7 English • Electrical safety precautions TIGHTEN AND CHECK ALL THE FITTINGS FOR CONNECTION BETWEEN PUMP, FLEXIBLE HOSE AND SPRAY GUN BEFORE USING THE EQUIPMENT. OPTIC EXCALIBUR English F2 • Check the mains voltage corresponds to the equipment’s rating. Voltage F1 • F3 CHECK ON POWER SUPPLY Make sure that the electrical system is earthed and complies with regulations. 8 The supply cable is provided without plug. Use a plug which guarantees the plant earthing. Only a technician or a skilled person should perform the connection of the plug to the electric cable. OPTIC EXCALIBUR • Lift the suction pipe and dip it into the solvent tank. • Ensure the gun (F3) is without nozzle. English Should anyone use an extension cable between the tooling and the socket, it must have the same characteristics as the cable supplied (minimum diameter of the wire 2.5 mm2) with a maximum length of 50 mt. Higher lengths and lower diameters can provoke excessive voltage falls and also an anomalous working of the equipment CONNECTION OF THE TOOLING TO THE POWER SUPPLY • Check the switch (F4) is on the “OFF” (0) position before connecting the cable to the mains. • Place the pressure control knob (F5) on the “MIN” position (turn counterclockwise). F3 OFF • Press the switch (F4) of the equipment “ON” (I). • Turn clockwise the pressure control knob (F5) so as the machine works at idle speed. ON F4 F5 WASHING OF THE NEW EQUIPMENT • The equipment has already been adjusted at our factory with light mineral oil left inside the pumping group as protection. Therefore, wash with diluent before sucking the product. F4 9 F5 OPTIC EXCALIBUR Point the gun (F6) into a container (F7) keeping the trigger pressed (so as to drain the oil inside) till a clean solvent comes out. Now, release the trigger. English • Never use products containing halogen hydrocarbons (as methylene chloride). If these products come into contact with aluminium parts of the equipment, can provoke dangerous chemical reactions with risk of explosion. F6 F7 G WORKING START OF THE PAINTING OPERATIONS • Remove the suction pipe and take away the solvent tank. • Point the gun into the solvent tank and press the trigger so as to recover the residual solvent. • As the pump idles, press the “OFF” (0) switch to stop the tooling. • Use the tooling after performing all the SETTING UP operations above described. • Dip the suction pipe (G1) into the product tank.

In addition, it is recommended to keep away from the pump in order to avoid the contact between the solvent fumes and the electric motor. • Now the machine is ready. Should you use water paints, besides the solvent wash, a wash with soapy and then clean water is suggested. • Insert the gun trigger lock and assemble the nozzle. Delivery pipe • G2 PREPARATION OF THE PAINT • Make sure the product is suitable to be used with a spray gun. • Mix and filter the product before using it. For filtration, use CLOSE-MESH (ref. 214) and LARGE-MESH (ref.215) LARIUS METEX braids. Make sure the product to be used is compatible with the materials employed for manufacturing the equipment (stainless steel and aluminium). Because of that, please contact the supplier of the product. 10 Open the recirculating-safety valve (G2) (turn clockwise so as the pin slides on the cam track). OPTIC EXCALIBUR • Press the switch “ON” (I) of the equipment and turn a little the pressure control knob clockwise (G3), so as the machine works at the idle speed. SPRAY ADJUSTMENT Slowly turn clockwise the pressure control knob to reach the pressure value in order to ensure a good atomization of the product. • An irregular and marked spray on the sides indicates a low working pressure. On the contrary, a too high pressure causes a high fog (“overspray”) and waste of product. • In order to avoid overthickness of paint, let the gun advance sideways (right-left) when spraying. • Always paint with regular parallel bands coats. • Keep a safety and constant distance between the gun and the support to be painted and also keep yourselves perpendicular to it. G3 NEVER point the spray gun at yourselves or at other people. The contact with the casting can cause serious injuries. In case of injuries caused by the gun casting, seek immediate medical advice specifying the type of the product injected. • Make sure the product recycles from the return tube (G4). • Close the recirculating-safety valve (G5) (turn clockwise till the valve has released). Recirculating-safety valve: when working at the maximum pressure available, releasing the gun trigger sudden increases of pressure can occur. In this case, the recirculating-safety valve opens automatically eliminating part of the product from the recirculating tube. Then it closes so as to go back to the first working conditions. G5 H CLEANING AT THE END OF THE WORK • Now the machine carries on sucking the product till the flexible hose is full, up to the gun. Then it will stop automatically. 11 • Reduce pressure to the minimum (turn counterclockwise the pressure control knob (H1) ). • Press the switch (H2) placed on the box of the electric motor, to stop the equipment.
