EXCALIBUR LINER

A

WORKING PRINCIPLE

The 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.

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.

1 2

SOLID LINE BROKEN LINE

ExCALIbUR LINER is ideal for medium marking and maintenance 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.

The line-marker is equipped with pivoting frontal wheel which even increases the agility of the larger models.

High yield, high efficiency, high versatility.

This line-marker utilises non-premixed paints. This allows it to achieve about 30 % more yield with respect to standard linemarkers. 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.

GENERAL MAINTENANCE

CHECK ON THE PACKING NUT

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 .

Discharge the pressure in the pump unit (open

the discharge valve) before carrying out any 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.

• 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.

K

ROUTINE MAINTENANCE

Always check that there is oil in the motor.

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.

K1

Ref. 16325

Oil ring

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.

17

EXCALIBUR LINER

• For tightening, use the wrench supplied (ref. 11503) .

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.
