your hands, body or other.
- Do not point the spray gun towards yourself or anyone else.
- Do not spray without the special nozzle guard.
- Discharge the pressure of the system after spraying and before performing any maintenance
operations.
- Do not use components whose operating pressure is less than the maximum pressure of
the system.
- Do not allow children to use this machine.
If the fluid penetrates the skin, the wound may seem like a “simple cut” but, in reality, it
could be a very serious injury. Immediately provide medical treatment to the affected area.
It indicates important recommendations about disposal and recycling process of products in
accordance with the environmental regulations.
It is obligatory to wear suitable clothing as gloves, goggles and face shield.

The pump is earthed through the earth cable
of the supply.
The gun is earthed through the high pressure

All the conductors near the work area must
be earthed.

FEED HOSE SAFETY
The fluid in the feed hose may be extremely hazardous. If
there is a leak from the hose or a cut or rupture due to wear
or damage or incorrect use,the fluid that leaks out may cause
fluid penetration damage or may seriously damage objects.
EQUIPMENT MISUSE HAzARD
Any misuse of the dispensing equipment or accessories,such
as overpressurizing, modifying parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them to rupture and result in serious injury, including
fluid injection and splashing fluid in the eyes or on the skin,
or in fire, explosion or property damage.
FLUID INJECTION HAzARD
•Donotattempttoreconnectthefeedhosesorrepairthem
with tape or any other method.
•Handleandroutehosescarefully.
MEDICAL ALERT – FLUID INJECTION WOUNDS
If any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE CUT.
Tell the doctor exactly what fluid was injected.
Injection into the skin is a traumatic injury. It
is important to treat the injury surgically as
soon as possible. Do not delay treatment to
research toxicity.
Toxicity is a concern with some exotic materials
injected directly into the blood stream. Consul-
tation with a plastic surgeon may be advisable.
The maximum working pressure of the gun is
280 bar. Do not exceed the maximum Working
pressure.
Be sure all fluids and solvents used are che-
mically compatible with the “WETTED PARTS”
shown in the TECHNICAL DATA. Always read the
fluid and solvent manufacturer’s literature be-
fore using any fluid or solvents in your system.
Before each use, check the entire hose for cuts,
leaks, abrasion, bulging cover, or damage or
movement of the hose couplings.
• Tighten all fluid connections securely before each use.High
pressure fluid can dislodge a loose coupling or allow high
pressure fluid to be emitted from the coupling
•Neveruseadamagedhose.Ifanyoftheseconditionsexist,
replace the hose immediately.
Do not pull on hoses to move equipment.
Do not use fluids or solvents which are not com-
patible with the inner tube and cover of the hose.
Do not expose hose to extreme temperatures;
check with your hose supplier to determine
temperature tolerance.
Proper hose grounding continuity is essential to maintaining a
grounded dispensing system.Check the electrical resistance
of your fluid hoses at least once a week. If your hose does
not have a tag on it which specifies the maximum electrical
resistance, contact the hose supplier or manufacturer for the
maximum resistance limits.
Usearesistancemeterintheappropriate range for your hose to
check the resistance. If the resistance exceeds the recom-
mended limits, replace it immediately. An ungrounded or
poorly grounded fluid hose can make your system hazardous.
The fluid that the spray gun shoot may
penetrate the skin and body causing
severe damage, including the need for
amputation. Fluid that penetrates or is
sprayed into the eyes or onto the skin
can also cause serious injury.
Do not place hands or fingers on the nozzle.
Do not clean the residues that form around the
nozzle until the pressure has been completely
discharged. Do not try and stop leaks with your
hands or body.
Be sure that all dispensing equipment and accessories are
properly rated to withstand the pressures developed by your
system. Never exceed the maximum working pressure of
your gun model.

CONDITIONS OF GUARANTEE
FIRE OR EXPLOSION HAzARD
Static electricity is created by the flow of fluid through
the pump and hose. If every part of the equipment is not
properly grounded, sparking may occur, and the system
may become hazardous.
Sparks may also occur when plugging in or unplugging a
power supply cord. Sparks can ignite fumes from solvents
and the fluid being dispensed, dust particles and other
flammable substances, whether you are pumping indoors
or outdoors, and cause a fire or explosion, serious injury,
and property damage.
Do not plug in or unplug any power supply cords
in the dispensing area when there is any chance
of igniting fumes still in the air.
If you experience anystatic sparkingorfeeleven
a slight shock while using this equipment,STOP
DISPENSING IMMEDIATELY. Check for proper
grounding of the entire system. Do not use the
system again until the cause of the problem is
identified and corrected.
Before flushing, be sure the entire system and
flushing pails are properly grounded. Refer
to GROUNDING, above. Always use the lowest
possible fluid pressure, and maintain firm
metal-to-metal contact between the gun and
grounded metal pail during flushing to reduce
the risk of fluid injection injury, static sparking
and splashing.
GROUNDING
To reduce the risk of static sparking, ground the pump and
all other equipment used or located in the dispensing area.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment and be
sure to ground all of the following equipment.
•Pump:groundthepumpbyconnectingagroundingwire
from the pump’s grounding lug to a true earth ground.
•Aircompressororhydraulicpowersupply:groundaccording
to local code and manufacturer’s recommendations.
•Fluidhoses:useonlygroundedhoseswithamaximumof
150 mt. Combined hose length to ensure grounding conti-
nuity. Refer to hose grounding continuity, above.
•Flo-gun:obtaingroundingthroughconnectionaproperly
grounded fluid hose and pump.
•Fluidsupplycontainer:accordingtolocalcode.
•All solventpailsusedwhenushing: according to local
code. Use only metal pails. Do not place the pail on a non-
conductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
MOVING PARTS HAzARD
Moving parts can pinch or amputate your fingers or other
body parts. Keep clear of moving parts when starting or
operating your system.
Before checking or servicing the gun, pump, or any other
system component follow the PRESSURE DISCHARGING
PROCEDURE to prevent the pump from starting accidentally.
The conditions of guarantee do not apply in the
following situations:
- improper washingandcleaning of components
causing malfunction, wear or damage to the
equipment or any of its parts;
- improper use of the equipment;
- use that does not conform with applicable
national legislation;
- incorrect or faulty installation;
- modifications,interventions and maintenance
that have not been authorised by the manu-
facturer;
- use of non-original spare parts or parts that
do not correspond to the specific model;
- total or partial non-compliance with the in-
structions provided.
