Operational Description
This Advance HD Spray Gun is a professional quality gun designed with both high volume, low
pressure (HVLP) technology or EPA compliant, Trans-Tech® technology. The ADVANCE HD is
suitable for a wide range of paints, dyes, stains, glazes and lacquers.
IMPORTANT: These Sprayguns are suitable for use with both waterbased and solvent based
coating materials. These guns are not designed for use with highly corrosive and/or abrasive
materials and if used with such materials it must be expected that the need for cleaning and/or
replacement of parts will be increased. If there is any doubt regarding the suitability of a specific
material, contact your DeVilbiss Distributor or DeVilbiss direct.
NOTE: This gun is not to be used with halogenated hydrocarbon solvents or cleaning agents
such as 1,1,1,-Trichloroethane or methylene chloride. These solvents can react with the
aluminium components used in this gun and cup. The reaction can become violent and lead to
an equipment explosion.

SAFETY WARNINGS
Fire and explosion
Solvents and coating materials can be highly flammable or combustible when sprayed.
ALWAYS refer to the coating material supplier’s instructions and COSHH sheets before
using this equipment.
Users must comply with all local and national codes of practice and insurance company
requirements governing ventilation, fire precautions, operation and house-keeping of
working areas.
This equipment, as supplied, is NOT suitable for use with Halogenated Hydrocarbons.
Static electricity can be generated by fluid and/or air passing through hoses, by the
spraying process and by cleaning non-conductive parts with cloths. To prevent ignition
sources from static discharges, earth continuity must be maintained to the spray gun
and other metallic equipment used. It is essential to use conductive air and/or fluid
hoses.
Personal Protective Equipment
Toxic vapours – When sprayed, certain materials may be poisonous, create irritation or
be otherwise harmful to health. Always read all labels, safety data sheets and follow any
recommendations for the material before spraying. If in doubt, contact your material
supplier.
The use of respiratory protective equipment is recommended at all times. The type of
equipment must be compatible with the material being sprayed.
Always wear eye protection when spraying or cleaning the spray gun.
Gloves must be worn when spraying or cleaning the equipment.
Training – Personnel should be given adequate training in the safe use of spraying equipment.
Misuse
Never aim a spray gun at any part of the body.
Never exceed the maximum recommended safe working pressure for the equipment.
The fitting of non-recommended or non-original spares may create hazards.
Before cleaning or maintenance, all pressure must be isolated and relieved from the equipment.
The product should be cleaned using a gun-washing machine, and should be removed and dried
immediately after cleaning is completed. Prolonged exposure to cleaning solutions can cause
damage to the product.
Noise Levels
The A-weighted sound level of spray guns may exceed 85 dB (A) depending on the setup being used. Details of actual noise levels are available on request. It is
recommended that ear protection is worn at all times when spraying.
Operating
Spray equipment using high pressures may be subject to recoil forces. Under certain
circumstances, such forces could result in repetitive strain injury to the operator.

INSTALLATION
For maximum transfer efficiency, do not use more
pressure than is necessary to atomise the material
being applied. NOTE: when using the 505, HVLP
setup do not exceed 1.3 bar inlet pressure.
1.
9.
10.
Connect the gun to a clean, moisture and oil free
air supply using a conductive hose, of at least 8
mm I.D.
NOTE
Depending on hose length, larger I.D. hose may
be required. Install an air gauge at the gun
handle. When gun is triggered on, adjust
regulated pressure to 2.0 bar for Trans-tech
Aircaps and 1.3bar for HVLP. Do not use more
pressure than is necessary to atomise the
material being applied. Excess pressure will
create additional overspray and reduce transfer
efficiency.
NOTE
If quick connect couplings are required, use only
high flow quick connects approved for HVLP
use. Other types will not flow enough air for
correct gun operation.
NOTE
If an air adjusting valve is used at the gun inlet,
use DGIPRO-502-bar Digital Gauge. Some
competitive adjusting valves have significant
pressure drop that can adversely affect spray
performance. The DGI Digital Gauge has
minimal pressure drop, which is important for
HVLP spraying.
11.
12.
13.
14.
PREVENTIVE MAINTENANCE &
CLEANING
To clean air cap and fluid nozzle, brush exterior with
a stiff bristle brush. If necessary to clean cap holes,
use a broom straw or toothpick if possible. If a wire or
hard instrument is used, extreme care must be used
to prevent damaging the holes which will cause a
distorted spray pattern.
To clean fluid passages, remove excess material
from cup, or disconnect hose for pressure models,
then flush with gun wash solution. Wipe the gun
exterior with a dampened cloth. Never completely
immerse in any solvent or cleaning solutions as this
is detrimental to the lubricants and life of the spray
gun.
2. SUCTION MODELS ONLY. Attach the cup lid
assembly (62) to the fluid inlet connector (54).
Position the yoke at right angles to the gun with
the cam lever to the front (see picture). Make
sure the vent hole in drip free diaphragm (60) is
180° to the lid vent hole. The position of the Drip
Free Valve (63) is not important.
3.
NOTE
When replacing the fluid nozzle or fluid needle,
replace both at the same time. Using worn parts can
cause fluid leakage. See page 14, Chart 2. Also,
replace the needle packing at this time. Torque the
fluid nozzle to 9–11 nm. Do not over tighten.
PRESSURE FEED MODELS. Connect the fluid
supply hose to Fluid inlet Connector (54).
NOTE
Before using the spraygun, flush it with solvent
to ensure that the fluid passages are clean.
CAUTION
To prevent damage to fluid nozzle (8) or fluid
needle (15), be sure to either 1) pull the trigger
and hold while tightening or loosening the fluid
nozzle, or 2) remove fluid adjusting knob (18) to
relieve spring pressure against needle collar.
OPERATION (SUCTION MODELS)
1.
2.
3.
Test spray. If the finish is too dry, reduce airflow
by reducing air inlet pressure.
If finish is too wet, reduce fluid flow by turning
fluid adjusting knob (18) clockwise. If atomisation
is too coarse, increase inlet air pressure. If too
fine, reduce inlet pressure.
The pattern size can be reduced by turning
spreader valve knob (23) clockwise.
Hold gun perpendicular to surface being
sprayed. Arcing or tilting may result in uneven
coating.
The recommended spray distance is 150-200
mm.
Spray edges first. Overlap each stroke a
minimum of 75%. Move gun at a constant speed.
Always turn off air supply and relieve pressure
when gun is not in use.
Mix coating material to manufacturer’s
instructions and strain material.
Fill the cup to no more than 20 mm from the top
of the cup. DO NOT OVERFILL.
Attach to Cup Lid.
SUCTION CUP. Empty excess material and clean
the cup. Make sure the vent holes in the Diaphragm
(60) and the lid (63) are clear.

Heavy right or
left side pattern
Remedies for the top-heavy, bottom-heavy, right-heavy, and left-heavy patterns:
1. Determine if the obstruction is on the air cap or the fluid nozzle. Do this by making a test spray pattern. Then,
rotate the cap one-half turn and spray another pattern. If the defect is inverted, obstruction is on the air cap.
Clean the air cap as previously instructed. Also check for dried paint just inside the cap centre hole opening;
remove by washing with solvent.
2. If the defect is not inverted, it is on the fluid nozzle. Clean nozzle. If problem persists, renew nozzle.
