SAFETY WARNINGS
Fire and explosion
Solvents and coating materials
can be highly flammable or
combustible when sprayed.
ALWAYS refer to the coating material
suppliers instructions and COSHH
sheets before using this equipment
Users must comply with all local and
national codes of practice and
insurance company
requirements governing
ventilation, fire precautions,
operation and house-keeping of working
areas
This equipment, as supplied,
is NOT suitable for use with
Halogenated Hydrocarbons.
Static Electricity can be
generated by fluid and/or air
passing through hoses, by the
spraying process and by
cleaning non- conductive parts with
cloths. To prevent ignition sources from
static discharges, earth continuity must
be maintained to the spraygun and other
metallic equipment used. It is essential to
use conductive air and/or fluid hoses.
Personal Protective
Equipment
Toxic vapours – When sprayed,
certain materials may be
poisonous, create irritation or be
otherwise harmful to health.
Always read all labels and safety data
sheets for the material before spraying
and follow any recommendations. If In
Doubt, Contact Your Material Supplier
The use of respiratory protective
equipment is recommended at all
times. The type of equipment
must be compatible with the
material being sprayed.
Always wear eye protection when
spraying or cleaning the spraygun
Gloves must be worn when
spraying or cleaning the
equipment
Training – Personnel should be given
adequate training in the safe use of
spraying equipment.
Misuse
Never aim a spraygun at any part of the
body
Never exceed the max. recommended
safe working pressure for the equipment
The fitting of non-recommended or non-
original spares may create hazards
Before cleaning or maintenance, all
pressure must be isolated and relieved
from the equipment
The product should be cleaned using a
gun washing machine. However, this
equipment should not be left inside gun
washing machines for prolonged periods
of time.
Noise Levels
The A-weighted sound level of
sprayguns may exceed 85 dB
(A) depending on the set-up
being used. Details of actual
noise levels are available on request. It is
recommended that ear protection is worn
at all times when spraying.
Operating
Spray Equipment using high pressures
may be subject to recoil forces. Under
certain circumstances, such forces could
result in repetitive strain injury to the
operator.

Installation
Important: To ensure that this
equipment reaches you in first class
condition, protective coatings have been
used. Flush the equipment through
with a suitable solvent before use.
1. Attach air hose to connector (13).
Recommended hose size 8 mm
bore. The hose must be conductive
and electrical bond from the
spraygun to earth should be
checked with an ohmeter. A
resistance of less than 106Ohms is
recommended.
2. Attach the Cup Lid assembly (27) to
the Fluid Inlet connector (15).
3. Position the Yoke at right angles to
the Gun with the Cam lever (21) to
the front (see picture). Make sure
the vent hole in the lid is positioned
under the Yoke and the hole in the
diaphragm (25) is 180° to the Lid
vent hole.
1. Turn off air and relieve pressure in
the supply lines, or if using QD
system, disconnect from airline.
2. Release Cup and raise the tube out
of the material. Trigger the Gun and
allow material to drain back into the
cup. Dispose of the surplus material.
3. Clean the cup. Remove the Drip free
diaphragm and clean.
Preventative Maintenance
Operation
1. Mix coating material to
manufacturers instructions.
2. Fill the cup with the required amount
of material. Fill to no more than
25mm (1“) from the top of the cup.
DO NOT OVERFILL.
3. Attach Cup to the Lid assembly.
4. Turn needle adjusting screw (7)
clockwise to prevent movement.
5. Turn spreader valve (5) counter-
clockwise to fully open.
6. Adjust inlet air pressure (For
recommended figures see
Specifications) at the gun inlet with
the gun triggered. (pressure gauge
attachment shown under
Accessories is recommended for
this).
7. Turn needle adjusting screw counter
clockwise until first thread shows.
8. Test spray. If the finish is too dry
reduce airflow by reducing air inlet
pressure or by the Airflow Valve (14).
Screw the Adjusting Knob (14) in to
reduce pressure.
9. If finish is too wet reduce fluid flow
by turning needle screw (7)
clockwise or reducing the fluid
pressure. If atomisation is too
coarse, increase inlet air pressure. If
too fine reduce inlet pressure.
10. The pattern size can be reduced by
turning adjusting valve (5) clockwise.
11. Hold gun perpendicular to surface
being sprayed. Arcing or tilting may
result in uneven coating.
12. The recommended spray distance is
150-200 mm (6”-8”).
13. Spray edges first. Overlap each
stroke a minimum of 50%. Move gun
at a constant speed.
14. Always turn off air supply and relieve
pressure when gun is not in use.

the diaphragm if is split or
damaged.
4. Check the breather hole in the Lid
is not blocked.
5. Remove air cap (1) and clean. If
any of the holes in the cap are
blocked with coating material use a
toothpick to clean. Never use metal
wire which could damage the cap
and produce distorted spray
patterns
6. Ensure the tip of the nozzle (2) is
clean and free from damage. Build
up of dried paint can distort the
spray pattern.
7. Lubrication – stud/screw (6), needle
(9) and air valve (11) should be
oiled each day.
Nozzle (2) and Needle (9) – Remove
parts in the following order: 7, 8, 9, 1
and 2. Replace any worn or damaged
parts and re-assemble in reverse order.
Recommended tightening torque for
nozzle (2) 9.5-12 Nm (80-100 lbf in).
Packing – Remove parts 7, 8, 9.
Unscrew cartridge (4). Fit new cartridge
finger tight. Re-assemble parts 9, 8,
and 7 and tighten cartridge (4) with
spanner sufficient to seal but to allow
free movement of needle. Lubricate
with gun oil.
Air Valve Seal Kit (16) - (Refer to
photos 1 to 28)
1. Remove Adjusting Knob (7), Spring
(8), and Needle (9).
2. Loosen Housing (10).
3. Remove Housing (10) and Airvalve
Spring.
4. Remove Valve (11).
5. Using Service Tool SPN-7, engage
groove behind the Valve Seat.
6. Remove Valve Seat.
7. Push out the Front Airvalve Seal
with a finger.
8. Turn the Gun upside down and let
the Seal fall out.
9. Fit New Front Seal to Service Tool.
10. Fit new Seal to gunbody and press
firmly to ensure Seal is engaged.
11. Fit New Valve Seat to Service
Tool.
12. Fit Valve Seat to Gunbody.
13 Remove Rear Airvalve Seal from
housing (10) with a hooked
instrument.

17 Replace Valve Spring and screw in
Housing (10).
18 Tighten Housing.
19 Screw reverse end of Service tool i
nto housing until fully engaged.
Tighen by hand to seat the Valve
Seat. Remove tool.
20 Fit Needle (9).
21 Fit Spring (8) and Knob (7).
22 Adjust Needle Packing (4) with
Spanner sufficient to seal but to
allow free movement of needle.
Lubricate with gun oil.
Spreader valve (5) – Caution: always
ensure that the valve is in the fully open
position by turning screw fully counter-
clockwise before fitting to body.
