A WORKING PRINCIPLE
The LARIUS EXCALIBUR unit is defi ned “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 re-duction 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 product is sucked, pushed towards the pump outlet and then
sent to the gun through the fl exible hose. 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.

F SETTING-UP
CONNECTION OF THE FLEXIBLE HOSE TO THE GUN
• Connect the high pressure fl exible hose (F1) to the pump (F2) and to the gun (F3) ensuring to tighten the fi ttings (the use of two wrenches is suggested).
NEVER use sealants on fi ttings’ 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 fl exible hose.
• NEVER SPRAY OVER FLAMMABLE PRODUCTS OR SOL-VENTS IN CLOSED PLACES.
• NEVER USE THE TOOLING IN PRESENCE OF POTEN-TIALLY EXPLOSIVE GAS.
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 fl exible hose. All the conductors near the work area must be earthed.
Always check the product is compatible with the materials composing the equipment (pump, spray gun, fl exible hose and accessories) with which it can come into contact. Never use paints or sol-vents 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.
• TIGHTEN AND CHECK ALL THE FITTINGS FOR CONNEC-TION BETWEEN PUMP, FLEXIBLE HOSE AND SPRAY GUN BEFORE USING THE EQUIPMENT.
• ALWAYS USE THE FLEXIBLE HOSE SUPPLIED WITH STANDARD KIT. 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.
IF THE PRODUCT TO BE USED IS TOXIC, AVOID INHALATION AND CONTACT BY USING PRO-TECTION GLOVES, GOGGLES AND PROPER FACE SHIELDS.
TAKE PROPER SAFETY MEASURES FOR THE PROTECTION OF HEARING IN CASE OF WORK NEAR THE PLANT.
Electrical safety precautions

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).
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
• Lift the suction pipe and dip it into the solvent tank.
• Ensure the gun (F3) is without nozzle.
• Press the switch (F4) of the equipment “ON” (I). • Turn clockwise the pressure control knob (F5) so as the

• 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.
• 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.
PREPARATION OF THE PAINT
• Make sure the product is suitable to be used with a spray gun.
• Mix and fi lter the product before using it. For fi ltration, use CLOSE-MESH (ref. 214) and LARGE-MESH (ref.215) LA-RIUS METEX braids.
Absolutely avoid to spray solvents indoors. 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.
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.
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.
• 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.
G WORKING
START OF THE PAINTING OPERATIONS
• Use the tooling after performing all the SETTING UP ope-rations above described.
• Dip the suction pipe (G1) into the product tank.
• Open the recirculating-safety valve (G2) (turn clockwise so as the pin slides on the cam track).

• Make sure the product recycles from the return tube (G4).
• Close the recirculating-safety valve (G5) (turn clockwise till the valve has released).
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.
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 fi rst working conditions.
H CLEANING AT THE ENDOF THE WORK
• 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.
• 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.
• Now the machine carries on sucking the product till the fl exible hose is full, up to the gun.
Then it will stop automatically.
