It indicates a risk for accident or serious damage to equipment if this warning is not followed.
It indicates important warnings and suggestions about disposal and recycling of the product in accordance with the environmental
regulations.
FIRE AND EXPLOSION DANGER
Flammable fumes, such as thinners or painting fumes could ignite or explode.
In order to prevent fire or explosion risks:
- Use the equipment ONLY in a well ventilated area. Keep the working area free from scrap materials.
- Remove all ignition sources such as pilot lights, cigarettes, portable electric lamps and plastic drop cloths (potential static span)
- Ground the equipment and all conductive items located in the work area.
- Use only conductive airless tubes, duly grounded.
- Never use trichloroethane, methylene cloride, any halogenated hydrocarbon thinners or fluids containing such thinners with aluminium
equipment under pressure. This use could cause a dangerous chemical reaction with expolsion risk.
- Do not connect or switch lights on or off if the air contains flammable fumes.
In case of electrical shocks, immediately stop the operation being carried out on the equipment.
Keep a fire extinguisher near the working area.
It indicates the risk of finger injury or crushing due to movable parts in the equipment.
Keep far from movable parts.
Do not use the equipment without the suitable protections.
Before any inspection or maintenance of the equipment, carry out the decompression procedure explained in this manual preventing
any risk of the equipment starting unexpectedly.
They report the risk of chemical reaction or explosion.
There is a risk of injury or serious damage related to contact with the jet from the spray gun. If this should occur, IMMEDIATELY contact
a doctor, indicating the type of product injected.
Do not spray before placing the guard over the nozzle and the trigger on the spray gun.
Do not put your fingers in the spray gun nozzle.
Once work has been completed, before carrying out any maintenance, complete the decompression procedure explained in this manual.
It indicates the presence of a clamp with grounding cable.
Use ONLY 3-wire extension cords and grounded electrical plugs.
Before starting work, make sure that the electrical system is grounded and complying with safety standards.
The high pressure product spraying out of the gun or from any lacks could cause body injury. To prevent any fire or injury risk:
- Use the safety block on the gun trigger when you are not spraying.
- Do not put hands or fingers on the gun nozzle. Never try to stop any lack with your hands or body.
- Do not direct the gun towards yourself or anyone else.
- Never spray without the suitable nozzle protection.
- Decompress the system at the end of the spraying process and before any maintenance operation.
- Do not use any components having an operating pressure lower than the system max pressure.
- Do not let the children use the equipment.
- Pay attention to the possible recoil when you trig the gun.
Should the high pressure fluid penetrate through the skin, the wound could appear similiar to a “simple cut” even if the damage is more
serious. Immediately contact a doctor to medically treat the wound part.
They indicate the obligation to wear suitable clothing as gloves, goggles and face shield.
Wear clothing that complies with the safety standards in force in the country in which the equipment is used.

WORKING PRINCIPLE
VEGA 23:1 pump is a pneumatic pump for high pressure painting
without the use of compressed air (AIRLESS). The stainless steel
version is particularly suitable for use with water-based paints.
The pump is essentially composed of an air motor and a structure
known as “Product Pumping Unit”, or simply the “Pumping Unit”.
In the pneumatic motor, the compressed air causes the vertical
reciprocating movement of the motor piston; this movement is
transmitted through a connecting rod to the product pumping piston.
This allows the pump to suck the product and to feed it towards
the outlet.
The ratio 23:1 means that the outlet pressure of the product is 23
times higher than the pump feed air pressure.
The unit comes complete with a transportation trolley, a high-
pressure product filter, an air supply regulator for the pump, a
product suction tube (complete with filter) and a recirculation tube.
Our spray guns are tested and controlled in our factory and are
derivered to the customer in perfect working conditions.
For this rason, in order not to alter the characteristics of these
units, it is advisable to carefully read these instructions and to
follow them accordingly.
