SAFETY
FIRE OR EXPLOSION HAZARD
1. Lacquering materials applied with the device may be flammable or explosive:
-Use the spray gun in well-ventilated lacquering cabins.
-Avoid ignition sources, including open fire, electric arc, etc.
2. 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.
3. In order to avoid static discharges - earth the painted object and spraying equipment.
HAZARDS DUE TO IMPROPER OPERATION
1. NEVER turn the spray gun outlet towards the human body.
2. NEVER exceed the maximum working pressure.
3. Cut off the compressed air and lacquering material supply hoses before performing any servicing and
maintenance operations.
HAZARDS INVOLVED IN SPRAY GUN OPERATION
1. Vapours generated during the operation of the spray gun may cause intoxication and health problems.
-Use the spray gun in well-ventilated rooms.
-Always wear safety goggles, gloves and face-masks for protection against harmful substances.
2. The noise level reported in the specifications has been measured at a distance of 1 metre from the head, and
at a height of 1.6 m.
-Apply personal protective equipment for your hearing, and breaks in work (working time shall not
exceed 4 hours).
OTHER HAZARDS
1. DO NOT modify the spray gun in any way.
2. NEVER perform any work within the range of operation of robots, conveyors, etc., unless these machines are
disabled.
3. NEVER spray any foodstuffs and/or chemical compounds.
PREPARATION
IMPORTANT
-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.
1. Connect compressed air hose - terminal no. 5-1.
2. Fasten paint tank - terminal no. 5-2.
3. Wash the spray gun with a proper solvent.
4. Fill the tank with lacquering material, and perform a test spray in order to adjust the spray gun.

3
PREPARATION
The recommended supply air pressure ranges from 1.7 to 2.0 bar in order to obtain best flow efficiency.
Keep the distance between the spray gun and painted surface ranging from 100 to 200 mm.
Maintain liquid outflow at a minimum level within a range that which will allow uninterrupted work.
This will guarantee a higher quality of applied coat owing to better material atomisation. The spray gun should always be
held perpendicular to the painted surface and moved along a horizontal straight line.
The viscosity of the material being applied should range from 15 to 23 sec., depending on its characteristics and painting
conditions. (Recommended Ford cup no. 4.)
MAINTENANCE
ATTENTION
CUT OFF THE COMPRESSED AIR SUPPLY HOSE AND EMPTY THE TANK CONTAININGTHE LACQUERING
MATERIAL BEFORE 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 tool immediately after use.
2) Clean other spray gun elements using the brush provided.
3) Carefully wash paint flow conduits before the spray gun disassembly.
4) Disassemble the nozzle after having removed the needle or with the 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 its full opening position, and then tighten up the pilot
sleeve in the spray gun body.
ATTENTION
-Use only original ANEST IWATA spare parts.
-Never immerse the whole spray gun in a solvent.
-Protect head holes, nozzle and needle against damage.

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