WORKING PRINCIPLE
MIST-LESS painting combines the qualities of airless technology
with those of low-pressure application providing superior quality
finishing with less material waste.
The MIST-LESS sprayguns allows:
- 15-35% product saving
- Overspray reduced to the minimum
- High quality finishing
The MIST-LESS sprayguns are equipped with a self-cleaning
nozzle with the following advantages:
- Reduced maintenance
- Long working life
- The nozzle does not have to be removed for cleaning, but simply
turned 180°, based on the same principle as Fast-Clean.
INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin.
To help prevent injection, always:
- Engage trigger lock when not spraying.
- Do not put your hand over the spray tip. Do not stop or deflect leaks with your hand, body or other.
- Do not point gun at anyone or at any part of the body.
- 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
- 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.

• Open the pump drain valve to help relieve uid pressure
in the pump, hose, and gun. Have a container ready into
which to drain the material, then pull the trigger to release
the pressure.
• Leave the drain valve open until you are ready to dispense
again.
E
Never put hand or fingers over the nozzle.
Never wipe off build-up around the fluid nozzle
until pressure is fully relieved and the gun trigger
lock is engaged.
Never try to stop or deflect leaks with your hand
or body.
This is a high pressure dispensing gun.
Fluid dispensed under high pressure could
be injected through your skin and into your
body. This could cause extremely serious
injury, including the need for amputation.
Also, fluid injected or splashed into the
eyes or on the skin can cause serious
damage.
FLUID INJECTION HAZARD
Always follow the Pressure Relief Procedure, at right, before
cleaning or removing the fluid nozzle or servicing any system
equipment.
FPRESSURE RELIEF
PROCEDURE
To reduce the risk of serious injury, including fluid injection, splashing
in the eyes or on skin, always follow this procedure whenever the
dispensing equipment is shut off, when checking or servicing any
part of system, when installing, cleaning or changing nozzles and
whenever you stop dispensing.
• Fully release the gun trigger and set the gun trigger lock by
rotating the trigger lock forward.
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 theblood stream.Consultation
with a plastic surgeon may be advisable.

English
If you suspect that the nozzle or hose is clogged or
that pressure has not been fully relieved, after
following the steps above, very slowly loosen the
hose end coupling and relieve pressure gradually;
then loosen completely. Now clear the nozzle or
hose obstruction.
H
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.
The maximum working pressure of the gun is
140 bar. Do not exceed the maximum Working
pressure.
IHOSE SAFETY
High pressure fluid in the hoses can be very dangerous.If the hose
develops a leak, split or rupture due to any kind of wear, damage
or misure, the high pressure fluid emitted from it can cause a fluid
injection injury or other serious injury or property damage.
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.
Be sure all fluids and solvents used are chemically
compatible with the “WETTED PARTS” shown in
the TECHNICAL DATA. Always read the fluid and
solvent manufacturer’s literature before 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.
• Do not try to recouple high pressure hose or mend it with
tape or any other device. A repaired hose cannot contain the
high pressure fluid.
• Handle and route hoses carefully.
• Tighten all uid 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
compatible 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.
Use a resistance meter in the appropriate range for your hose to
check the resistance. If the resistance exceeds the recommended
limits, replace it immediately. An ungrounded or poorly grounded
fluid hose can make your system hazardous.
L
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.

10
MIST-LESS GUN
English
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 any static sparking or feel even 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.
MMOVING PART 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 RELIEF PROCEDURE (see
page 8) to prevent the pump from starting
accidentally.
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 continuity.
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.
• To maintain grounding continuity when ushing or relieving
pressure always hold a metal part of the gun firmly to the
side of a grounded metal pail, then trigger the gun.
