A WORKING PRINCIPLEThe LARIUS ExCALIbUR unit is defined “piston pump”. An piston pump is used for high pressure painting without air (from this process derives the term ”airless”). The internal combustion engine, mounted upon the undercarriage, powers the alternative piston pump.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 flexible hose. A electronic device, allows to adjust and control the pressure of the material coming out of the pump.A safety valve avoiding overpressure, guarantees the total reliability of the equipment.

The control zone allows for the possibility of:

• Activating the dispensing spray gun;

• Enabling or disabling the frontal steering wheel;

• Adjust the pressure of work;

This type of equipment is capable of painting one line at a time in a single color.The line can be either solid or dotted, based on the working requirements.

SOLID LINE

1 2

BROKEN LINE

ExCALIbUR LINER is ideal for medium marking and mainte-nance jobs.

Use water or non-refractive solvent filtered paint specifically designed for airless application.

ExCALIbUR LINER allows for the marking and maintaining of all types lines on highways, freeways, pedestrian crossings, parking lots and squares, as well as every horizontal marking required by the highway code.Airless marking has numerous proven benefits with respect to line-markers with pressurised tanks, which have been rendered obsolete by airless-technology line markers.

Airless line-marking guarantees: • Decreased Environmental Impact;• Decreased drying time.

This line-marker utilises non-premixed paints. This allows it to achieve about 30 % more yield with respect to standard line-markers. Every model is also an airless spray gun which can be used in the construction/decoration sector together with washable products, enamels, breathable paints and flooring resins.A vast assortment of accessories is available to satisfy every customer demand.

The paint dries quickly and the line is defined in a uniform manner with a single coat. The airless function requires the use of filtered paint which is specifically designed for airless application. This means that the paint is homogeneous, of a smooth and uniform consistency and will not form crusts, nor will it become gelatinous or thick. With this airless line-marker, the paint adheres firmly to all types of pavement, with optimal visibility, and is resistance to wear caused both by traffic as well as atmospheric agents.

In the LARIUS models, the paint canister can be loaded directly upon the undercarriage or else poured into the non-stick, 50 L tank. In every case, cleaning, maintenance and colour change operations are facilitated.

The line-marker is equipped with pivoting frontal wheel which even increases the agility of the larger models.High yield, high efficiency, high versatility.

SETUP PROCEDURE

• Use the tooling after performing all the SETTING UP opera-tions above described.

• Check that there is enough unleaded petrol.

• Open the product output tap (H1).

• Start the motor following the indications provided in the chapter “STARTING THE MOTOR”.

• Make sure that the re-circulation/safety valve (H2) is closed (spray enabled).

ADJUSTING PUMP UNIT SPEED

• Move the motor acceleration lever (H4) gently to increase or decrease the speed of the pump.

During the painting operation it is normally recommended to maintain the position of the accelerator lever (H4) at about 3/4 of its maximum run.

• Press the switch (H3) of the equipment “ON” (I).

• Turn the pressure adjustment handle clockwise until the desired setting has been reached.

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.

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.

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.

• Pull the lever on the right (H5) to activate the spray gun and begin working, advancing the machine in a continuous man-ner.

GENERAL MAINTENANCE

DAILY

• Clean the filters;• Clean the nozzles;• Clean all the varnish circuit with a specific product;• Check the fuel motor (see the maintenance table).

PERIODICALLY • Check the pumping gaskets draft (if the product draws, replace

gaskets);• Clean the mobile parts from the varnish deposits (spray guns,

etc.); • Check the gun cables tightening, the wheel block;• Check that the tubes and all the fittings are correctly locked.

J CHECK ON THE PACKING NUT

Discharge the pressure in the pump unit (open the discharge valve) before carrying out any maintenance.

Daily check the packing nut is tight in order to avoid wastes but not excessively to prevent the piston from seizing and the gaskets from wearing.

• Use the lubricant (K1) supplied (ref. 16325) to allow an easy sliding of the piston inside the gasket group.

Daily top up the packing nut.

At the start of each working day check that the ring nut is full of hydraulic oil (Ref. 16325). This oil makes it easier for the piston to slide and prevents any material that escapes via the seal gasket drying when the equipment is stopped.

ROUTINE MAINTENANCE

Always check that there is oil in the motor.

K

Check the motor oil every 100 working hours via the relevant measuring caps positioned on the bottom of the petrol motor. Top up if necessary.
