SAFETY
FIRE OR EXPLOSION HAZARD
1.
2.
3.
Lacquering materials applied with the device may be flammable or explosive. Use the spray gun in wellventilated lacquering cabins. Avoid ignition sources, including open fire, electric arc, etc.
Never use chlorinated hydrocarbons (e.g. trichloroethylene, ethyl chloride, etc.) as solvents, because they may
react chemically with aluminium and zinc-coated elements and bring about explosions. Make sure that the
solvents being used are safe in contact with aluminium and zinc. In case of doubts contact your solvent
supplier.
In order to avoid static discharges - earth the painted object and spraying equipment.
HAZARDS DUE TO IMPROPER OPERATION
1.
2.
3.
4.
Never turn the spray gun outlet towards the human body.
Never exceed the maximum working pressure.
Cut off compressed air and lacquering material supply hoses before performing any servicing and maintenance
operations.
The spray gun needle has a sharp tip. It is forbidden to touch the needle tip and/or bring it close to the human
body.
HUMAN BODY PROTECTION
1.
2.
3.
4.
Work with the spray gun only in large and ventilated rooms (lacquering cabins). Failure to follow this
instruction may result in intoxication and/ or fire.
Always wear working clothing (safety goggles, face-mask, gloves). Lacquers and substances used in the
lacquering industry are toxic. If you feel that something wrong has happened to your eyes or skin, immediately
contact a doctor.
Wear earplugs if necessary. Noise level generated while painting does not exceed 85 dB (A).
Stop work whenever you feel tired. Pressing the release trigger makes your hand tired, and the
lacquering process may affect your physical and mental state.
OTHER HAZARDS
1.
2.
3.
Do not modify the spray gun in any way.
Never perform any work within the range of operation of robots, conveyors, etc., unless these machines are
disabled.
Never spray any foodstuffs and/or chemical compounds.
-
This spray gun should be operated by a trained worker.
Make sure that the spray gun has not been damaged in transport.
Supplied air has to be dry and pure.
4.
If any element of the spray gun does not work or works abnormally, immediately stop work and
continue only after having eliminated the defect.

IMPORTANT: Preparation for work
1.
2.
3.
4.
Connect the compressed air hose.
Fasten the paint tank.
Wash the spray gun with a proper solvent.
Fill the tank with the lacquering material, and perform a test spray in order to adjust the spray gun.
Make sure that the air connected to the spray gun is sufficiently pure and dry. If the spray gun is being used for the first
time, carefully loosen the nozzles, press the release trigger and let it go. If the trigger does not return to its original
position, loosen the needle seal knob. Make sure that the air hose is fastened well to the coupling, and the paint tank is
securely closed.
OPERATION
The recommended supply air pressure ranges from 2.0 to 3.0 bar. Keep the distance between the spray gun and painted
surface ranging from 100 to 200 mm in order to obtain the best flow efficiency.
Maintain liquid outflow at a minimum level within a range that will allow not uninterrupted work. This will guarantee a
higher quality of applied coat owing to better material atomisation. The spray gun should be always held perpendicular to
the painted surface and moved along a horizontal straight line. The viscosity of the material being applied should range
from 12 to 23 sec., depending on its characteristics and painting conditions. (Ford cup no. 4.)
MAINTENANCE
ATTENTION
Cut off the compressed air supply hose and empty the tank containing the paint before the commencement of
any servicing and maintenance operations. Proceed with care during the spray gun disassembly so as not to get
hurt in contact with sharp elements. Read these instructions thoroughly before attempting the spray gun
disassembly.
1) Remove paint residues and wash conduits and the nozzle by spraying a small amount of solvent through the spray
gun.
Careless washing may result in disturbances in the jet shape.
In case of binary materials wash the spray gun immediately after use.
2) Clean other spray gun elements using a brush or cleaning rod.
3) Carefully wash paint flow conduits before the spray gun disassembly.
4) Disassemble the nozzle after having removed the needle or with release trigger pressed - in order to protect the
nozzle from damage.
5) Assemble the needle unit by screwing in the needle seal manually, and then carefully tighten it up with a spanner/key.
Adjust the seal pressure by releasing the trigger and checking if the needle returns to its “closed” position quick enough
and all the way.
6) Turn the jet adjustment knob anticlockwise, until it reaches full opening position, and then tighten up the pilot sleeve in
the spray gun body.
ATTENTION
Use only original AIR GUNSA spare parts. Never immerse the whole spray gun in a solvent. Protect head holes,
nozzle and needle against damage.

DISTURBANCES DURING OPERATION
Fault
Pulsation
Crescent
Skew
Reason
1. Air penetrates between the nozzle and its
tapered seat in the body.
2. Air is drawn in through the head seal.
1. Lacquer residues inside the head, partially
clogged head holes. Different air pressure in
both nozzles.
1. Lacquer residues on nozzle hole edges,
or damaged central hole in the head.
2. Loose nozzle.
1. Too low lacquer viscosity.
Splitting
2. Too high liquid outflow.
1. Too low lacquer viscosity.
Remedy
1. Unscrew the nozzle in order to clean the
seat – replace if damaged.
2. Seal the head.
1. Remove soiling from head holes. Do not
use metal objects to do this.
1. Remove soiling from the nozzle or replace
it if damaged.
1. Add more lacquer in order to increase
viscosity.
2. Adjustment with needle jet control knob.
1. Reduce lacquer viscosity.
Separate stains
Spitting
2. Too high liquid outflow.
1. Nozzle and needle are incorrectly
mounted.
2. Too short stroke of release trigger
opening air flow.
3. Lacquer residues inside the head.
4
2. Increase liquid outflow.
1. Clean or replace nozzle and needle.
2. Replace air valve unit.
3. Clean the head.
