• Do not use this machine when under the inuence of drugs or alcohol.
• Do not modify the equipment under any circumstances.
• Use products and solvents that are compatible with the various parts of the equipment, and read the manufacturer’s warnings carefully.
• See the Technical Details for the equipment given in the Manual.
• Check the equipment for worn parts once a day. If any worn parts are found, replace them using ONLY original spare parts.
• Keep children and animals away from work area.
• Comply with all safety standards.
• It indicates an accident risk or serious damage to equipment if this warning is not followed.
FIRE AND EXPLOSION HAZARD
• Solvent and paint fumes in work area can ignite or explode.
• To help prevent fire and explosion:
- Use equipment ONLY in well ventilated area.
- Eliminate all ignition sources, such as pilot lights, cigarettes and plastic drop cloths (potential static arc).
- Ground equipment and conductive objects.
- Use only grounded hoses.
- Do not use trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or uids containing such solvents in
pressurized aluminium equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death,
serious injury, and property damage.
- Do not form connections or switch light switches on or off if the air contains inammable fumes.
• If electrical shocks or discharges are encountered the operation being carried out using the equipment must be stopped immediately.
• Keep a re extinguisher at hand in the immediate vicinity of the work area.
• It indicates wound and nger squashing risk due to movable parts in the equipment.
• Keep away from moving parts.
• Do not use the equipment without the proper protection.
• Before any inspection or maintenance of the equipment, carry out the decompression procedure explained in this manual, and prevent
any risk of the equipment starting unexpectedly.
• Report any risk of chemical reaction or explosion if this warning has not been given.
• (IF PROVIDED) There is a risk of injury or serious lesion related to contact with the jet from the spray gun. If this should occur, IMME-
DIATELY contact a doctor, indicating the type of product injected.
• (IF PROVIDED) Do not spray before the guard has been placed over the nozzle and the trigger on the spray gun.
• (IF PROVIDED) Do not put your ngers in the spray gun nozzle.
• Once work has been completed, before carrying out any maintenance, complete the decompression procedure.
• It indicates important recommendations about disposal and recycling process of products in accordance with the environmental
regulations.
• Mark any clamps attached to earth cables.
• Use ONLY 3-wire extension cords and grounded electrical outlets.
• Before starting work make sure that the electrical system is grounded and that it complies with safety standards.
• High-pressure uid from gun, hose leaks, or ruptured components will pierce skin.
• To help prevent injection, always:
- (IF PROVIDED) Engage trigger lock when not spraying.
- (IF PROVIDED) Do not put your hand over the spray tip. Do not stop or deect leaks with your hand, body or other.
- (IF PROVIDED) Do not point gun at anyone or at any part of the body.
- (IF PROVIDED) Never spray without tip guard.
- Do pressure relief if you stop spraying or being servicing sprayer and before any maintenance operations.
- Do not use components rated less than sprayer Maximum Working Pressure.
- Never allow children to use this unit
- (IF PROVIDED) Brace yourself; gun may recoil when triggered.
If high pressure fluid pierces your skin, the injury might look like “just a cut”, but it is a serious wound!
Get immediate medical attention.
• It is obligatory 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.
• Do not wear bracelets, earrings, rings, chains, or anything else that may hinder the operator’s work.
• Do not wear clothing with wide sleeves, scarves, ties, or any other piece of clothing that could get tangled up in moving parts of the
equipment during the work, inspection, or maintenance cycles.

FOR CONNECTION BETWEEN PUMP, FLEXIBLE HOSE AND
SPRAY GUN BEFORE USING THE EQUIPMENT.
• ALWAYS USE THE FLEXIBLE HOSE SUPPLIED WITH STAN-
DARD 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.
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
flexible hose.
All the conductors near the work area must be
earthed.
Avoid approaching too much to the pump piston
rod when the pump is working or under pressure.
A sudden movement of the piston rod can cause
wounds or finger squashing.
Never spray over flammable products or solvents
in closed places.
Never use the tooling in presence of potentially
explosive gas.
Always check that the product is compatible with
the materials composing the equipment (pump,
spray gun, flexible hose and accessories) with
which it can come into contact. Never use paints
or solvents 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.
If the product to be used is toxic, avoid inhalation
and contact by using protection gloves, goggles
and proper face shields.
Take proper safety measures for the protection
of hearing in case of work near the plant.

The preheater is an electrically-operated explosion-proof equipment and can be combined with airless and air spray systems.
A green indicator light (1) indicates that the connection to the power line has been made. The uid is heated through an electrical
resistor that sends the heat generated to the spiral stainless-steel tube that ows inside the preheater body.
The temperature of the uid detected by the thermometer (2) can be adjusted by acting on the appropriate adjustment knob (3). The
switching on of the red temperature indicator light (4) indicates that the chosen temperature has been reached, while a thermostat
ensures that its value remains constant. If the thermostat does not act due to a fault in itself or in the probe connected to it, when
the temperature inside the preheater reaches 130°, the safety thermostat triggers and opens the electrical circuit, thus interrupting
the supply of current.

ELECTRICAL CONNECTION
ROUTINE MAINTENAINCE • Always remember to clean the preheater after use to prevent
the fluid from solidifying inside it when it cools down.
• Disconnect the electrical connection and let the fluid circulate for
a few minutes until the preheater has cooled down before using
the solvent for washing, thus avoiding the sudden expansion of
the solvent inside the preheater due to the heat with consequent
increase of pressure.
Always disconnect the power supply before
carrying out any type of check or replacement
of the electrical components of the preheater.

Beforeinstallation, carefully readthe informationin
the use and maintenance manual. All maintenance
operations must be carried out according to the
instructions in the manual.
Do not open the preheater when powered. To
open the lid, disconnect the power and wait at
least 30 minutes.
• The preheater must be installed and maintained in accordance
with the installation and maintenance standards for
environments classified against the risk of explosion due to
the presence of gases and vapors (example: EN60079-14,
EN 60079-17 or other national regulations/standards).

Check that the polyurethane foam inserted in the
lid is not damaged.
The preheater must be properly earthed by means
of the anti-loosening and anti-rotating device.
Make sure that the earthing of the preheater is
always guaranteed and ensured.
The user must periodically check, depending on the type of use and the substances used:
• the state of wear and correct operation of the preheater;
• the presence of abnormal vibrations and/or noises. In this case, stop the preheater, identify the causes and contact the manufacturer.
Nonetheless, residual risks may be present during normal preheater operation if:
• is not subject to the normal maintenance plans provided for in the use and maintenance manual;
• is not used as required by the project specifications.
