ED. 20 - 07/2020 - Cod. 150153

Use water or non-refractive solvent filtered paint
specifically designed for airless application.
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.
WORKING PRINCIPLE
The LARIUS EXCALIBUR unit is dened “piston pump”.
An piston pump is used for high pressure painting without air
(from this process derives the term ”airless”).
Theinternal combustionengine,mounted upon theundercarriage,
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 relia-
bility 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 BROKEN LINE
EXCALIBUR LINER is ideal for medium marking and mainte-
nance jobs.
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.
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 line-
markers. Every model is also an airless spray gun which can be
usedinthe construction/decoration sectortogetherwith washable
products, enamels, breathable paints and flooring resins.
A vast assortment of accessories is available to satisfy every
customer demand.

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 first wor-
king conditions.
CLEANING AT THE END WORK
• Eliminate the paint remaining within the tank (N4) by placing
the re-circulation tube (N5) into a container.
• Open the recirculating-safety valve (N6).
ADJUSTING PUMP UNIT SPEED
• Move the motor acceleration lever (M3) 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 (M3) at about 3/4
of its maximum run.
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
(M4) to activate the spray gun
and begin working, advancing the machine in a continuous
manner.
•Reduce pressure to the minimum (turn counterclockwise the
pressure control knob (N1) ).
• Release the residual pressure by holding down the trigger
of the gun (N2) and pointing it into a container (N3).

equipment.
• Turn the pressure adjustment handle (N1) to minimum (pump
stopped).
• Shut off the motor.
• Turn the pressure adjustment (N1) handle slightly clockwise
to make the machine function at minimum pressure (pump
activated) , until the tank has been completely emptied then
shut off the pump by bringing the handle (N1) to its minimum
position.
• Fill the tank (N4) with wash fluid.
• Clean the walls of the tank with a brush.
• Turn the pressure adjustment (N1) handle slightly clockwise
to make the machine function at minimum pressure (pump
activated).
• Make sure the re-circulation tube
(N5) is inserted into a
container and wait for clean wash uid to come out of it.
• Turn the pressure adjustment handle (N1) to minimum (pump
stopped).
• Place the re-circulation tube back into the tank.
• Keep the gun’s trigger pressed to release any residual pres-
sure.
• Remove the nozzle from the gun and wash it separately.
• Closed the recirculating-safety valve
• Turn the pressure adjustment handle (N1) slightly clockwise
to make the machine function at minimum pressure (pump
activated).
• Point the manual gun (N7) into a container (N8), drain the
residual paint and wait for the wash uid to come out clean

GENERAL MAINTENANCE
D ischarge the pressure in the pump unit (open
the discharge valve) before carrying out any
maintenance.
ROUTINE MAINTENANCE
Always check that there is oil in the
motor.
At the start of each working day check that the
ring nut is full of hydraulic oil (Ref. 16340). 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.
DAILY
• Clean the filters;
• Clean the nozzles;
• Clean all the varnish circuit with a specific product;
• Check the fuel motor (see the maintenance table).
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.
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.
• Use the lubricant (P1)supplied (ref. 16340) to allow an easy
sliding of the piston inside the gasket group.
Daily top up the packing nut.
PERIODICALLY
• Checkthepumping 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.
