Warnings
43A5097C
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this
equipment. The exclamation point symbol alerts you to a general warning and the hazard
symbols refer to procedure-specific risks. When these symbols appear in the body of this
manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols
and warnings not covered in this section may appear throughout the body of this manual
where applicable.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help
prevent fire and explosion:
•Do not spray flammable or combustible materials near an open flame or sources of ignition
such as cigarettes, motors, electrical equipment, and plastic drop cloths (potential static
sparking).
• Turbine motor generates sparks. Keep sprayer in a well ventilated area at least 20 feet (6 m)
from the spray area when spraying, flushing, cleaning, or servicing. Do not spray pump
assembly.
•Connect to a grounded outlet and use grounded extensions cords. Do not use a 3-to-2
adapter.
•Do not use a paint or a solvent containing halogenated hydrocarbons.
•Do not spray flammable or combustible liquids in a confined area.
•Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area.
•Do not smoke in the spray area or spray where sparks or flame is present.
•Do not operate light switches, engines, or similar spark producing products in the spray
area.
•Keep area clean and free of paint or solvent containers, rags, and other flammable
materials.
•Know the contents of the paints and solvents being sprayed. Read all Safety Data Sheets
(SDSs) and container labels provided with the paints and solvents. Follow the paint and
solvents manufacturer’s safety instructions.
•Keep a working fire extinguisher in the work area.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and
cause serious injury.
•Follow the Pressure Relief Procedure when you stop spraying/dispensing and before
cleaning, checking, or servicing equipment.
•Tighten all fluid connections before operating the equipment.
•Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

Warnings
3A5097C 5
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Always wear appropriate gloves, eye protection, and a respirator or mask when painting.
•Do not operate or spray near children. Keep children away from equipment at all times.
•Do not overreach or stand on an unstable support. Keep effective footing and balance at
all times.
•Stay alert and watch what you are doing.
•Do not operate the unit when fatigued or under the influence of drugs or alcohol.
•Do not kink or over-bend the hose.
•Do not expose the hose to temperatures or to pressures in excess of those specified by
the manufacturer.
•Do not use the hose as a strength member to pull or lift the equipment.
•Do not alter or modify equipment. Alterations or modifications may void agency approvals
and create safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious
chemical reaction and equipment rupture. Failure to follow this warning can result in death,
serious injury, or property damage.
•Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents.
•Do not use chlorine bleach.
•Many other fluids may contain chemicals that can react with aluminum. Contact your
material supplier for compatibility.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin,
inhaled, or swallowed.
•Read SDSs to know the specific hazards of the fluids you are using.
•Store hazardous fluid in approved containers, and dispose of it according to applicable
guidelines.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury,
including eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective
equipment includes but is not limited to:
•Protective eyewear, and hearing protection.
•Respirators, protective clothing, and gloves as recommended by the fluid and solvent
manufacturer.

Disconnect tubing from gun to relieve
pressure in the cup.
5. If using a metal siphon cup:
Unlatch cup cover, loosen or remove cup
from cover to relieve pressure.
The spray gun cup is pressurized. To
reduce the risk of splashing from
pressurized fluid, always follow the
Pressure Relief Procedure before
removing cup.

Fluid and Work Piece
Preparation
•Strain fluids before spraying. This
includes colors, reducers and
hardeners.
•Use a slower drying reducer or thinner to
compensate for the faster drying time
caused by the warm air of the turbine. Do
not over reduce.
•Spray performance varies with the
viscosity of the material sprayed, HVLP
sprayer, and length of hose.
•Most material manufacturers provide
recommendations for their materials.
Follow these recommendations.
•For proper adhesion, ensure surface of
work piece is completely clean.
Fluid Set Selection
For best spray performance, select proper
fluid set for fluid being sprayed. Reference
the Fluid Set Selection Guide for the fluid
set recommended for your application. Fluid
set numbers are marked on fluid needles and
nozzles.

How to Spray

How to Spray
Take a few moments prior to spraying and
review these tips to ensure your spraying
project is a success.
Adjust Spray Pattern
Set air cap to position for spray pattern
desired.
Adjust Flow and Pattern Size
Edge II (Model 17R236)
Flow and pattern size is determined by how
far trigger is pulled.
Edge II (Model 17R351)
Fluid/Air Control:
Flow and pattern size is determined by
adjustment to the Fluid/Air control knob. Set
knob to OFF. Increase flow until desired finish
is attained.
Edge II Plus
Flow and pattern size is determined by
adjustment to the Fluid, Air and Pattern Size
controls.
The turbine motor generates sparks.
These sparks can ignite flammable fumes.
•Keep sprayer in a well ventilated area.
•Keep sprayer at least 20 feet (6m) from
spray area. Use additional hose if
necessary.

How to Spray

Fluid Control:
Set knob to OFF. Increase fluid until desired
flow is attained.
Air Control:
Start with air control at the +position. To
decrease atomization of fluid, adjust air
control toward the -position.
Pattern Size Control:
Additional control of the pattern size is
available by rotation of the air cap retaining
ring. Start with the fluid nozzle flush with the
center surface of the air cap. Pattern size can
be adjusted by rotating the retaining ring in
either direction.
Spray Techniques
Use a piece of scrap cardboard to practice
spraying techniques before spraying the
work piece.
•Always spray with the least amount of
pressure required to provide the desired
spray pattern and rate of application.
Spraying at pressures higher than
necessary wastes material and can
result in an orange peel finish.
•Aim gun straight at surface. Tilting gun to
direct spray angle causes an uneven
finish.
•Flex wrist to keep gun pointed straight.
Fanning gun to direct spray at angle
causes uneven finish.
