Operator’s Instructions
Use Ecco genuine parts and accessories only for best
function and safety.
Before starting, read through all instructions carefully.
Air spray guns used for spraying of liquids under
low pressure and low atomizing air pressure.
HVLP High Volume Low Pressure.
The high velocity flow of air and liquids through hoses and
nozzles may develop static electricity. Be sure that the
equipment, object being sprayed, spraybooth, paint and
waste container are properly grounded to prevent static
discharge or sparks.
WARNING
As the equipment works under pressure the utmost care must
be observed during the work. Bearing this in mind, never aim
the spray gun at a person or towards any part of the body In
the event of personal injury caused by the spraying pressure,
immediate medical attention is essential. Before carrying out
any adjustment or repair, the equipment must be switched
off and the paint pressure relieved.
WARNING
Important
Do not use halogenated hydrocarbons in coating application
equipment where aluminium or galvanized parts come
in contact with the solvent or coating material.
Halogenated hydrocarbons e.g. 1,1,1-thrichloroethane and
methylene chloride react, violently with such parts, causing
corrosion and danger for explosion.

Operation
• Install and operate the spray gun according to Fig. 1.
• Blow the paint and air hoses clean before connection.
• Check that all connections are tight (pay particular attention to
the connection between paint cup and spray gun).
• Keep the spray gun clean and lubricate moving parts at regular
intervals.
• Lubricants for surface-treatment equipment must not contain
silicon.
• In the event of leakage around the paint needle, tightening the
packing screws (3) from both sides. After tightening, check that
fluid needle is pushed forward by the spring force.
• For short standstill periods, for instance over a night, it will
suffice to clean the air and paint nozzles on the outside. If a
two-componentpaintisused, however, the gun must be flushed
through immediately with solvent. This must also be done if the
gun is to remain unused for a longer period of time.
• When cleaning the air cap and the paint nozzle, use a soft brush
or rag dipped in solvent. Do not place the entire gun in solvent,
as the oil on the lubricated parts would be dissolved. Blow the air
cap dry with compressed air from both sides.
• Never use iron or steel wire to clean air holes and ducts in
the nozzles.
Connections and controls (see Fig. 1)

4Fan width adjusting. If the knob is screwed all the way in a round
fan will be obtained other positions give broad fans.
16 Paint flow adjusting. Clockwise turning result in a smaller paint
flow and counter-clockwise turning increases the flow. The fluid
flow is regulated in the first instance by the choice of paint nozzle
and paint pressure.

42 Paint hose connection G 3/8.
Hose: Inside dia. 6.3 mm (1/4") or 9.5 mm (3/8").
Needle packing and needle
1. Remove the air cap (33), and the paint nozzle (32).
2. Unscrew the back head (14) by screwing the wheel (16) counter-
clockwise.
3. Remove the spring (15) and the paint needle (12).
4. Dismantle the front packing screw (29).
5. Dismantle the packing screws (3).
6. Pry out the the packing set (2). Clear out any remains of the
packings .
7. Clean everything well with cleaning agent and then blow out with air.
8. Assembly the packing (2 ) whith holes and the packing screw (29) on
the paint needle (12), tightening with a screwdriver.
9. Assembly the side packings (2) in the gun body. Advance the packing
screws (3) with a screwdriver from both sides until good friction is ob-
tained between the paint needle (12) and the packings (2).
10. Re-fit the paint nozzle (32) (screwing torque 22 Nm), squeeze the
trigger (17) to avoid damaging the tip of the paint needle, and refit the
air cap (33) by hand.
Distributor ring
1. Dismantle the distributor ring (30) by screving on the air cap (33) a few
turns. Withdraw the distributor ring axially from the gun body.
2. Assembly the distributor ring (30) by mating it with a pin (28) in the gun
body.
Fan width control
Check when fitting the valve housing (8) that the marking on the body
agrees with fig. below.
Paint spraying
Inhalation of paint, paint dust and solvent is not healthy. Make
sure an approved spraybooth is used. The operator must use
personal protection-breathing mask or fresh air hood.
CAUTION
Disassembly-Reassembly (see Fig. page 1)
(see also Fig. 2)
How to operate
Recommended paint viscosity differs according to paint properties
and painting conditions. 15 to 23 sec./Ford cup 4 is recommendable.
The gun is operate at low air pressure, high transfer efficiency will not
be obtained if the spray distance is to far.
Set the spray distance from the gun to the work piece as near as pos-
sible within the range of 150-200 mm.
Air caps
The air caps are tested and certified according to the SEAVA method.
This gives a ”finger print” of the spray pattern on each air cap.
For further information please contact your supplier.
The retaining ring for the air cap shall only be tightened with hand
force. No tools are required. Especially important when a capcleaner
is used.
Air caps can be sent back for checking and comparity the perform-
ance. For further interesting please contact your supplier.
Before reassembling the different components:
• Clean the parts with the appropriate cleaning agent by means
of brush.
• Install new seals after having lubricated them with PTFE grease.
• Install new parts if necessary.
Before any intervention on the spray gun, shot off and relieved
the compressed air supply and paint pressure to the gun.

Troubleshooting
Introduction
Always commence troubleshooting by checking the general condition
of the spray gun. This can most easily be determined by test spraying,
which provides an opportunity for checking the spray pattern and ca-
pacity, air leakage and gasket leakage.
Thefollowing external factors can causemalfunctioningandshould be
thoroughly checked:
1. The quality of the air, i.e. content of moisture, dirt particles and oil.
2. The quality of the paint, i.e. its viscosity, purity. etc.
3 The air and paint pressure in relation to viscosity of the paint and
nozzle combination used.
4. The size of the air/paint hoses.
Troubleshoouting chart
Correct Spray Pattern
Types of problems
Collection of information which makes it possible to identify the error
symptoms applicable to the spray gun in the event of malfunctioning
is a matter of vital importance. Identification of symptoms makes it pos-
sible to decide whether the spray gun itself is the direct cause of the
malfunctioning or if this may have been caused by an external factor.
Paint leaking Worn needle packings and/or needle. Replace damaged parts with new ones.
Paint leaking through the paint nozzle
when the gun is closed. Pollution between the needle and the nozzle or needle and nozzle worn or damaged. Unscrew air cap (33) and nozzle (32). Clean carefully and check for any sign of damages
or wear.
Paint leaking - Air leaking Cause Remedy
a) Dried paint on holes for atomizing air.
Clean the air holes, use appropriate clean-
ing agent and a soft brush.
b) Damage to holes for atomizing air.
Replace the air cap with a new one.
c) Air cap not sufficiently tightened.
Tighten the air cap properly by hand.
Asymmetrical to the left or
to the right
a) Dried paint on holes for atomizing air.
b) Damage to holes for atomizing air.
c) Air cap not sufficiently tightened.
Distorted in the middle
a) Damage to the tip of the paint nozzle.
b) The pressure of the atomizing air in relation
to the viscosity of the paint.
a) Fit a new paint nozzle.
b) Adjust the air pressure of the atomizing air.
Spray Pattern Cause Remedy
Narrowing off in the middle
a) Wrong nozzle combination.
b) Fan air pressurer too high.
c) Paint viscosity unsuitable.
d) Incorrect spray angle.
a) Select a new nozzle combination suitable
for the viscosity of paint.
b) Reduce the pressure of the fan air.
c) Adjust the viscosity of the paint.
d) Adjust the angle with the fan width control.
Irregular spray (spitting)
a) Paint needle gasket leaky.
b) Damaged O-ring in distributor ring.
c) Paint nozzle not tightened.
d) Dirt on sealing surfaces of paint nozzle and
distributor ring.
e) Paint hose connection not tightened.
f) Paint hose defective.
a) Adjust the packing screws. If this does not
suffice, change the paint needle gaskets.
b) Change the O-ring in the distributor ring.
c) Tighten the paint nozzle.
d) Clean the sealing surfaces of the paint
nozzle and distributor ring with solvent and
blow clean.
e) Tighten the paint hose connection.
f) Change the paint hose.
