Ope ra tor’s In struc tions
Use Ec co gen u ine parts and ac ces so ries on ly for best
func tion and safe ty.
Be fore start ing, read through all in struc tions care ful ly.
The high vel o ci ty flow of ma te ri al through ho ses and nozz les
may de ve lop sta tic elec tri ci ty. Be su re that the equ ip ment,
object being spray ed, spray booth, paint and was te con tai ner
are pro per ly groun ded to pre vent sta tic di schar ge orsparks.
Check the elec tri cal re sis tan ce of the high pres su re paint
ho se re gu la ry. The ope ra tor is nor mal ly con nec ted to earth
through the spray gun.
WAR NING
As the equipment works under very high pres su re the
ut most 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 bo dy In the event of personal injury caused by the
spray ing pressure, immediate medical attention is essential.
Before carrying out any adjustment or repair, the equipment
must be wit ched off and the paint pres su re re li e ved.
WAR NING
If the gun does not work satisfactorily it must on no ac count be
used. Repair or replace it immediately.
Im por tant
Do not use halogenated hydrocarbons in coating ap pli ca tion
equipment where aluminium or gal va ni zed parts come
in contact with the solvent or coating ma te ri al.
Ha log en at ed hydrocarbons e.g. 1,1,1-thri chlo ro et ha ne and
methylene chloride react, violently with such parts, causing
corrosion and dan ger for ex plo sion.

Trouble shooting
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 capacity
and gasket leakage.
The following external factors can cause malfunctioning and should be
thoroughly checked:
1. The quality of the paint, i.e. its viscosity, purity. etc.
2. The paint pressure in relation to viscosity of the paint and
spray tip used.
3. The size of paint hoses.
Trouble shoouting chart (see the last page)
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
possible 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.
Replacement of fluid needle and fluid needle
gaskets
Removal
1. Shut off pump and re lief paint pres sure.
2. Undo the two screws (19).
3. Remove the servo part (14) by screwing out the back head (15).
4. Unscrew the sealing element (4).
5. Withdraw fluid needle (12) and take away the washer (5).
6. Unscrew the guide bushing (11).
7. Press the packing set out with the aid of the 5-mm pinprovided in the
tool set. Note! Take care to avoid damaging the outside diameter of
the packing screw (10) which is a sealing surface. Use the flats of the
packing screw when clamping between the jaws of a vice.
8. Clean and inspect all parts.
Assembly
All moving parts must be lubricated
1. Mount the packing set on the fluid needle (12) in the following order:
The washer (5), the guide (6), the packings (7) with the o-rings (8)
and finally the sleeve (9). Note! The packings (7) are to be fitted with
the tip of the Vee facing away from the valve cone in the fluid needle.
2. Screw the assembled sealing element (4) into the gun body.
3. Drip a little oil onto the sealing surface of the packing screw and mount
the servo part (14).
4. Secured the fluid needle with the two lock screws (19).
Replacement of fluid needle only
1. Unscrew the retaining ring (29) and remove the spray tip (28) together
with its gasket (27)
2. Uns crew the fluid nozzle (3) with its gasket (2).
3. Undo the lock screws (19) and pull the fluid needle (12) out from the
front.
4. Insert a new fluid needle and tighten the lock screws (19).
5. Fit the fluid nozzle (3) and spray tip (28). Don’t forget to refit the gaskets
(2 and 27).
• Max. fluid pres su re 360 bar.
• Fluid ho se con nec tion 1/4-18 NPSM.
• Min./Max. control air pressure 4/8 bar.
• Control air tube con nec tion is elbow coupling for 6/8 mm nylon tubing.
• Blow the fluid and air tube clean before connecting them.
• When as ses sing the re ac tion ti me of the con nec ted spray gun
(the ti me from the start im pul se until spray ing com men ces) the
re ac tion time of the control valve must be taken into con si de ra tion.
• Re com men ded sizes for control val ve and air hoses:
– Con trol valve, 3-way, G1/4. Min. flow area 28 mm2.
Mechan i cally, pneu mat i cal ly or electrically actuated.
– Air hose, nylon, dia. 6/8 mm, max. Iength 7.5 m for control air.
• To prevent the fluid hose from getting stuck on account of dried
paint, it is recommended that the connection threads be greased
with vasseline or a similar lubricant.
• Ta ke gre at ca re to keep the spray gun clean and to lubricate all
mo ving parts at regular intervals.
• Lu bri cants for paint spraying equipment must not contain silicones.
• Check that all connections are tight.
• If the gun does not work satisfactorily it must on no account be used.
Repair or replace it immediately.
Paint spray ing
Ad vice on high-pres sure spray ing
1. Con sult your paint sup pli er for in for ma tion to choose the cor rect
spray tip for the ac tu al paint.
2. As rule the best spray ing dis tance is 30-40 cm.
3. The spray pass es do not need to over lap as much as in spray paint ing
with air atom i za tion.
4. The ca pac i ty of high pres sure spray ing is very large. To avoid runs, the
spray gun should usu al ly be moved fast er than in spray paint ing
with air atom i za tion.
Maintenance
The entire spray gun gun should be cleaned at the end of each working
day. The spray tip should be cleaned more frequently.
Wipe the spray gun thoroughly clean on outside and clean it internally by
flushing a suitable solvent through it.
More extensive cleaning and overhauling should be carried out at least
once a month, depending on the material being sprayed.
Trouble shoouting chart
Correct Spray Pattern
The paint is uniformly dipersed over the entire spray angle.
a) Increase the paint pressure. Not that too
high a paint pressure causes excessive
spray mist.
b) Thin the paint cautiously or change to a
different spray tip size or spray angle.
c) Choose the correct size of spray tip.
d) Clean the spray tip with solvent. Use a
brush and, if necessary, a sliver of wood.
e) Change the spray tip.
Symmetrical edge stripes
a) Paint pressure too low.
b) Paint viscosity too high.
c) Wrong choice of spray tip.
c) Spray tip orifies partly clogged.
d) Spray tip damaged.
Asymmetrical edge stripes
a) Spray tip damaged. a) Change the spray tip.
Spray Pattern Cause Remedy
Paint leaking
Paint leaking Worn needle packings and/or needle. Replace damaged parts with new ones.
Paint leaking through the spray tip when
the gun is closed. Pollution between the needle and the fluid nozzle
(3) or fluid needle (12) and nozzle worn or dam-
aged.
Clean carefully and check for any sign of damages
or wear.
