The viscosity, which is expressed in DIN/sec, is the time it takes for the paint to stop running as a continuous flow through the viscosity cup (Figure 2).
Fig.2
Your Spray Station 4900 comes with a fluid tip and a 2.5 mm needle fitted.
For the best results with products which are more runny (liquid dyes, varnishes, runny paints, wood dyes), we recommend that you attach the 1.5 mm
fluid tip-needle assembly to your spray station, included.
This applies for products which have a viscosity between 25 and 50 DIN/sec, i.e., which will take between 25 and 50 seconds to run through the vis-
cosity cup. Refer to the chapter on cleaning to see how the fluid tip and needle can be removed and switched for a smaller/larger fluid tip-needle
assembly.
7) OPERATION
Fill the container with the product to be sprayed.
Stir well (as mentioned above).
Make sure the feed tube (11) is firmly fitted into the base of the gun (in the base fitting from which nothing should be protruding.
The base fitting is designed to allow air to enter).
Screw the container to the base of the spray gun and tighten accordingly.
Unroll the motor unit air hose 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 gun trigger is pulled.
Pressing on the trigger pulls the fluid tip needle back slightly and releases some of the paint.
The amount of paint released depends on how far you pull the trigger.
Very important: when spraying for the first time, we recommend that you always leave the motor to run for 1 to 2 minutes before applying the product,
which allows the air to be slightly heated and makes it much easier to apply the product effectively.
8) SPRAYING TECHNIQUE
3 spray patterns
By slightly loosening the adjustment ring (at the front) you can turn the air cap a little (catch locking system) and obtain 3 different spray patterns:
Vertical spray Horizontal spray Round spray
The ‘crisscross’ technique (using the vertical and horizontal spray patterns)
The most commonly used technique for painting a wall is the ‘crisscross’ technique, i.e. you apply the product in horizontal lines and then cross over
these lines by applying the product in vertical lines;
1) Adjust the air cap 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 to obtain a horizontal spray and apply the product in horizontal lines over the lines you have just sprayed.
Cross over the horizontal lines (spayed with a vertical pattern) with vertical lines (sprayed with a horizontal pattern).
Depending on how far your arm can reach, apply your product using the ‘crisscross’ technique over areas of about 1m2.
Try to move your arm and pull the trigger in such a manner so as to achieve the most even spray possible. Don’t attempt to cover the
whole line in one go.
Round spray
This will be used for alcoves or even for small, round objects or finishing work.
Release the trigger to avoid
overspraying which will cause the
product to run.
