Work Stations
The spray gun should only be used as a handheld hand-operated
device. It is always recommended that the spray gun is used when
standing on the solid floor. It can be used in other positions provided the
spray gun is kept near vertical and the operator has a firm grip and
footing. Any work station must take account that the liquid being
sprayed should not be breathed in and the liquid can be highly
flammable and spraying should never be undertaken near naked flames
or hot surfaces. Do not smoke. It
should also takeaccount that not all of
the liquid being sprayed will be
applied to the object being sprayed
and account must be taken that this
surplus, i.e. “over spray” will be
deposited in the surrounding area.
Foreseen Use of Tool
This tool is an external mix, high capacity spray gun, designed for high
quality production spraying of paint and other finishing material from a
gravity plastic cup.
The material inlet is located directly on the top of the spray gun and the
air inlet is located at the bottom of the spray gun handle.
The fluid control knob and the air control knob are both located at the
rear of the spray gun, the pattern control knob is located at the left side
of the spray gun.

Operating
Prior to shipment, this gun was
treated with an anti corrosive agent,
before using this gun make sure that it is carefully flushed with thinners.
To use the gun, tighten the air cap with its stamping number in an
upward direction. Attach material cup to the gun. Attach an air supply
line to the ¼” BSP air inlet. Check for the correct tightening of nut (4) so
that no air will escape but air valve stem (13) still slides. Caution:
Never point spray gun at yourself or any other person. Accidental
discharge of material may result in serious injury. Adjust air pressure to
spray gun. Caution: Do Not exceed 100 psi. Depress spray gun
trigger to spray material. To adjust the amount of material released
(density of fan spray), turn the fluid control knob (15) (counter clockwise
to increase, or clockwise to decrease). To adjust the width of fan spray,
turn the pattern control knob (7) (counter clockwise to increase, or
clockwise to decrease). To adjust the air quality turn the Air Volume
control knob (18) (counter clockwise to increase, or clockwise to
decrease). Note: Care should be exercised when handling spray gun
to avoid damage to the orifice of the air cap and tip of fluid nozzle,
damage to these parts will result in irregular spray patterns

Dismantling & Assembly Instructions
It is important that the spray gun is cleaned after daily use. Cleaning is accomplished by
spraying an appropriate solvent or thinners through the system. Wipe the exterior of
the spray gun with a solvent soaked cloth or use the provided brush to remove any
accumulated material.
Exchange of nozzle set
When changing to another nozzle, make sure that the complete nozzle set is
changed. A set comprises of air cap, paint nozzle, and fluid needle.
Assemble fluid nozzle before putting in fluid needle.
Cleaning
Empty any material from the gravity feed cup and replace with a suitable solvent.
Operate trigger until material traces have disappeared and gun is thoroughly clean.
Wipe gun exterior with a solvent dampened cloth or use provided brush.
Note: If fluid nozzle (2) is to be removed for thorough cleaning squeeze trigger to
prevent damaging the fluid needle tip (16) when unscrewing nozzle.
Caution: Always exercise extreme care when using any solvent or thinners. Never
clean gun near fire, flames or any source of heat or sparks. Properly dispose of used
cleaning material.
Caution: Do Not soak entire spray gun insolvent or thinners for a long period of time
as this will destroy lubricants and possibly makes motion un smooth.
Never use lye or caustic alkaline solutions for cleaning; such solutions will attack the
aluminium alloy parts of the gun.
Important: Make certain that the air cap and fluid nozzle are kept clean at all times. If
necessary, remove these two components and soak them in solvent.
Do Not use metal instruments to clean air cap or fluid nozzles as an irregular spray
pattern may result.
After a thorough cleaning of the gun, the following lubrication procedures must be
observed to ensure affective high quality performance of the spray gun. Lubricate
working points (13) with straight mineral oil or caster oil. Periodically place a few drops
of oil on tapered sections of fluid nozzle (2) to ensure easy operation of the air cap.
When spraying water bases materials coat fluid nozzle inside and out with straight
mineral oil after use. Outer diameter of needle sleeve (7) of fluid needle assembly must
be lubricated occasionally with straight mineral oil.
Troubleshooting
Defective Pattern Likely Cause Suggested Remedy
Dried material is clogging side-port “A” and
causing side-port “B” to blow spray towards
the clogged side.
Soak side-ports in thinner to clean clog. Do not poke any open-
ing with metal objects.
Dired material at fluid nozzle “C” restricts air
flow.
Loose air nozzle
Air Pressure set too high.
Remove air nozzle. Wipe off fluid tip using a cloth soaked in
thinner or soft brush.
Fasten nozzle securely.
Reduce air pressure.
Spitting, irregular or fluttering spray Fluid nozzle cracked or worn.
Leak at thread of fluid nozzle.
Leak at fluid needle.
Needle Packing worn out.
Insufficient fluid in cup.
Vent hole in container cover clogged.
Tighten or replace.
Tighten fluid nozzle.
Tighten compression nut assembly or replace needle packing.
Replace packing.
Fill cup with fluid.
Clean out vent.
Split spray pattern. Air Pressure too high. Turn pattern knob c/w to decrease fan width. Turn fluid needle
adjusting nut c/w to increase fluid flow.
Unatomised or splattered spray. Material too heavy.
Insufficient air pressure.
Fluid pressure too high.
Dried material on tip of fluid nozzle or air jets of air cap.
Thin material or use larger orifice fluid nozzle set.
Increase pressure to within limit.
Reduce pressure.
Clean.
Inadequate air delivery Air needle partially closed.
Dried material in air jets of air cap.
Obstruction in air line.
Open control knob.
Clean.
Remove obstruction.
Excessive fog Air pressure too high for viscosity of fluid. Reduce air pressure and/or open fluid control knob.
Material leaking from fluid inlet cup Loose cup or foreign substances on/between cup thread and fluid
inlet.
Tighten and clean or replace it.
Material leak from nozzle when trigger is
released.
Worn fluid needle.
Dried material in tip of nozzle.
Loose packing nut.
Replace.
Clean.
Tighten Needle packing nut by turning counterclockwise.

Safety Rules
Do not assume that you are totally familiar with this unit until after
having read all warning tags, labels, nameplates, instruction sheets and
any other explanatory material completely and thoroughly. To avoid
accidents, this should be done by all persons before attempting to
operate, assemble or disassemble the gun or any other part of the
system.
Before disassembly or removal of any part of the gun or attached
components; shut off compressor, release pressure by depressing the
trigger and disconnect power source.
Never assume system pressure is zero!
Protect all lines against damage. Avoid Risk. If uncertain as to safe
conditions of hoses, replace with the same type of a suitable
replacement. (Do Not Repair).
To avoid creating an explosive atmosphere, work only in a well
ventilated area.
Use of a face mask is recommended to prevent inhalation of toxic
material.
Do Not attempt to unclog (back flush) spray gun by squeezing trigger
while holding your finger in front of the fluid nozzle.
Pressure may vary according to viscosity of material used. Maximum
working pressure is 70 psi.
Do not exceed pressure limit of gun or any other component
in system.
Prior to daily operation, make certain that all connections and fittings are
secure.
Check hose and all connections for weak or worn condition that could
render system unsafe. All replacement components such as hose or
fittings must have a working pressure equal to or greater than system
pressure.
Recommended spray distance 8” to 10”.
Warning
Halogenated hydrocarbon solvents for example: 1,1,1- trichloroethane
and methylene chloride- can chemically react with the aluminium in this
gun and cause an explosion hazard. Read the label or data sheet for the
material you intend to spray. Do not use spray material containing these
solvents with this spray gun.
