The concept
A motor feeds out a high volume of air (HV) and enables products to be sprayed at a low pressure
(LP). The product is released from the Fluid Tip of the Spray Gun at a very low pressure (0.18 bar)
and is enclosed in a high volume of air. The Air Hose feeds the air produced by the motor to the
Spray Gun.
The powerful motor can spray a wide range of paint with or without dilution. However, there will
always be some paint which will not be suitable for the Spray Gun. The good quality paint
contains a high percentage of dry particles which make the dilution easier. The users must keep in
mind that low temperatures make the paint thicker, that’s why we recommend spraying with the
Spray Gun with a 15°C minimum temperature.

PARTS LIST
• Carefully cover areas which are not to be painted with a plastic cover and protective tape.
• Wear a suitable mask when spraying products (and make sure there is adequate ventilation in
the room when working indoors).
• Clean the surface you are going to paint. As well as being clean, it must also be dry and
smooth.
• Practice first on some old wooden planks to make sure you are holding the Spray Gun correctly.
• We recommend you wear protective clothing
• Stir the paint well using a mixer where possible.
• Make sure there are no solid particles in the paint.
• Many products can be sprayed without being thinned. However, if the application is not good,
thin the product progressively in stages of 5%.
• Most paints can be sprayed by being thinned just a little, e.g. by 5% or 10%.
• Some thick paints such as outer wall paints and certain undercoats will need to be thinned by
20% or 25%.
• Use water to thin a water-based product.
• Use white spirit to thin a solvent-based product.
• Certain manufacturers will indicate on the can whether a specific thinner is to be used.

SPRAYING TECHNIQUE
VERY IMPORTANT: when spraying for the first time, we recommend you always leave the motor
to run for 1 to 2 minutes before applying the product. Do not forget that the Fluid Adjusting Screw
(12) controls the quantity of paint sprayed, for instance the more the Fluid Adjusting Screw (12) is
tightened the less paint is sprayed.
The viscosity, which is expressed in D N/sec, is the time it takes for the paint
to stop running as a continuous flow through the viscosity cup (Fig.1). Your
Spray Station 6900 comes with a 2.0mm Fluid Tip and a 2.0 mm Fluid Needle
fitted. For best results with products which are more runny (liquid dyes,
varnishes, runny paints, wood dyes), we recommend you purchase the 1.5
mm Fluid Tip and Fluid Needle. This applies for products which have a
viscosity between 25 and 50 D N/sec, i.e., which will take between 25 and 50
seconds to run through the viscosity cup. Refer to the chapter on cleaning to
see how the Fluid Tip and Fluid Needle can be removed and switched for a
smaller/larger Fluid Tip and Fluid Needle assembly.
• Fill the Paint Container (25) with the product to be sprayed. Stir well (as
mentioned above).
• Screw the Paint Container (25) to the base of the Spray Gun and tighten accordingly.
• Unroll the motor unit Air Hose (27) and attach it to the back of the Spray Gun.
• Unroll the power cable and attach the plug to the mains supply.
• Switch the Spray Station on. This will immediately cause some air to be produced, which is
quite NORMAL. However, none of the product will be sprayed until the Spray Gun trigger is
pulled.
Fig. 1
The most commonly used technique for painting a wall is the ‘criss-cross’ technique, i.e. you apply
the product in horizontal lines and then cross over these lines by applying the product in
vertical lines; (Fig.3).
Fig. 3
Let go of the trigger at the
end of each spray
movement to avoid
excessive paint and drips
1) Adjust the Air Cap (2) to obtain a Vertical spray, then pull the Trigger
and move your arm across to the right.
2) When you get to the end of the line, release the Trigger for a
moment and then apply the product in the opposite direction just
beneath the line you have sprayed.
3) Proceed in this manner applying the product in Horizontal lines one
underneath the other.
4) Next, adjust the Air Cap (2) to obtain a Horizontal spray and apply
>the product in horizontal lines over the lines you have just sprayed.

Type of paint Cleaning
Water-based paint Clean with water
Oil-based paint Clean with white spirit
Removing the Fluid Tip (4) and Fluid Needle (9) assembly (for cleaning or switching to a
smaller/larger diameter).

Flush out the residue paint from the spray gun, as follows:
lRemove the Paint Container (25) from the spray gun.
lPour any residual paint into its original container for future use.
lUse a cloth soaked in thinners to wipe out excess paint from the container, the underside of the
Lid (22) & the Gasket (23).
lPour a small quantity of clean thinners into the container, re-fit the container to the spray gun
and shake the gun lightly.
lNow spray all of the thinners through the gun.
lRepeat this each time using clean thinners until there is no trace of paint in the thinners
being sprayed.
To thoroughly clean the remainder of the spray gun, remove all working parts as per the
exploded spare parts drawing on page 3 as follows:
lLoosen and remove Air Cap Ring (1), Air Cap (2) and Air Direction Plate (3).
lNow unscrew the Adjusting Screw (12) and pull out the Needle (9) and Needle Spring (11).
lUse a suitable spanner to remove the Fluid Tip (4) and Fluid Tip Seal (5).
All of the components above can be immersed in thinners and cleaned using the cleaning kit
supplied with this product. After cleaning your spray gun and before fitting the needle, dip the tip
into some vaseline which will lubricate the gland washers as the needle is inserted.
• NEVER D SPOSE OF PA NTS OR SOLVENTS DOWN THE DRA N. ALWAYS USE
YOUR LOCAL WASTE COLLECT ON S TE.
CLEANING INSTRUCTIONS
SPRAY GUN
Release the trigger to avoid overspraying which will cause the product to run.
Cross over the horizontal lines (sprayed with a Vertical pattern) with vertical lines (sprayed with a
Horizontal pattern). Only the forearm must move not the wrist.

CAUSE ACTION REQUIRED
Paint too diluted Add undiluted paint
Paint output too high Reduce the paint output by
adjusting the Fluid Adjusting Screw (12)
Moving too slowly ncrease speed of application
Spray Trigger held for too long Release Trigger sooner
Spray Gun too close ncrease the distance between the Spray
Gun and the work surface
Paint too diluted Add undiluted paint
Paint output too low ncrease the paint output by
adjusting the Fluid Adjusting Screw (12)
Moving too fast Reduce speed of application
Gun clogged Clean the Spray Gun
Gun too far away Move the Spray Gun closer to the work
surface
Paint too thick Add thinners
Fluid Tip clogged Clean the Fluid Tip (4)
Pick-Up Tube clogged Clean Pick-Up Tube (18)
Air Hose split Replace Air Hose (14)
Grainy paint Filter the paint
Container almost empty Refill Paint Container (25)
Spray Gun at an angle Check that the Pick-Up Tube (18) is
pointing towards the paint
Air inlet blocked Check the condition of the Filter (26) and
clean if necessary
Gland seal not attached or
the wrong way round or not
tight enough.
Over time the gland seal
will wear and need adjusting
Reattach the Gland Seal (16) and
retighten Gland Nut (15).
To check the gland nut is
correctly fitted you will need a small
adjustable spanner. Pull the Trigger
back and gradually tighten the Gland Nut
.(15) but by turning it in a clockwise
.direction until the Needle (9) is not free to
.move when the trigger is released.
You move your wrist Move your forearm instead
Either too much or not enough
paint
Use the Fluid Adjusting Screw (12) to
.control the flow
PROBLEM
The paint drips onto
item being painted
Paint is too thin or
irregular
No paint being
released
Paint leaking from
the gland nut in
front of the Trigger
Too much paint in an
area
Pulverisation
