Information about the operating manual
This manual provides important information on how to work with the device safely and efficiently.
The manual is part of the device and must always be kept in the immediate proximity of the device
so that it is accessible to the personnel at all times.
The personnel must have read and understood this manual before starting any work. Compliance
with all specified safety information and instructions is a basic requirement for safe working conditions.
In addition, the local occupational safety regulations and general safety rules apply for the area of
application of the device.
Due to optional finishing variants, it is possible that the figures shown in this operating manual
deviate from your device.
Information about explosion protection
Many of our competitors have been marking their products with the Ex symbol as a matter of principle for some time now.
At Krautzberger we do not do that.
We engineer and manufacture our products in line with currently applicable directives.
If the labelling on the product is required, it is affixed to the product as the result of the necessary
analysis of ignition sources. If no labelling is affixed, the analysis of ignition sources and previous
experience with the assessment of the suitability of products for use in a potentially explosive area
have shown that the product described in this operating manual does not represent a potential
source of ignition, with the exception of an electrostatic charge.
Taking into account the potential equalisation (provided by proper earth connection), the use in an
area at risk for explosions is permitted in accordance with the currently valid directives.

ENGLISH
1 Function and identification
1.1 Function
Automatic spray guns are used for the
n automatic coating/marking of surfaces
n Dosing of fluids
n Placement of adhesive or marking points
Typical spray fluids are paints, dyes, adhesives, debonding agents, etc.
The spray fluid is fed into the automatic spray gun under pressure. This pressure is typically generated by pumps or pressure containers. The automatic spray gun is controlled via compressed air.
Upon opening, the control piston charged with compressed air initially opens the air nozzle and
then with a short delay the fluid nozzle of the spray gun. Upon closing, initially the fluid nozzle and
then the air nozzle is closed in order to prevent a subsequent dripping of the spray fluid.
For the precise control of the automatic spray gun, electrically-activated solenoid valves can be
used, for example. Switching times of 60 ms can be achieved this way.
The spray fluid is atomised using compressed air. The geometry of the spray jet and the sprayed
quantity of the spray fluid can be adjusted with the following measures:
n Selection of the air and fluid nozzle
n Changing of the atomiser air pressure
n Changing of the spray fluid pressure
n Adjustment of the needle stroke on the regulator of the automatic spray gun.
The automatic spray gun also features the following additional characteristics:
n Head section only in aluminium, hard-coated
n Main element with flat jet regulator
or with flat and round jet control

5.4 Connecting the automatic spray gun
See also ( Ä Chapter 5.3 ‘Connection scheme’ on page 18).
WARNING!
Danger of injury due to improper connection!
When the fluid supply is pressurised, e.g. from pressure containers or with pumps, the range
of the fluid jet can increase by a multiple in case of atomiser air failure. This presents a hazard
to people and property.
– Make sure that the fluid supply and the control air are interrupted if the atomiser air pres-
sure drops off quickly.
– It is recommended to regulate the atomiser air pressure via a filter pressure reducer.
The connections for control and atomiser air are marked with letter abbreviations.
Fig. 4: Connecting the automatic spray gun
1. Connect the control air to input "St" ( Fig. 4/3).
2. Connect the atomiser air to input "Z" ( Fig. 4/2).
3. Connect the material line to the connection ( Fig. 4/1) on the underside of the head section.

Fig. 5: Checking connections
2. Completely open the round jet control ( Fig. 5/2, if present) and the flat jet regulator (
Fig. 5/1) . To do this, turn the regulator anti-clockwise up to the stop.
3. Open the adjusting nut ( Fig. 5/3) of the needle stroke adjustment maximum 5.5 mm. To do
so, turn the adjusting nut anti-clockwise.
One turn of the needle stroke adjustment moves the needle by 1 mm and corresponds
to 18 positions.
No air may escape from the automatic spray gun.
ð
4. Open the control air.
The needle of the fluid nozzle must push itself back and air must escape from the air
ð
nozzle.
5. Close the control air again.
6. Establish fluid supply.
No spray fluid may escape from the spray gun.

6.3 Operation
To achieve optimal results, adhere to the following:
– Rinse the automatic spray gun with cleaning products before commissioning.
– Too-high air pressure causes unnecessarily high air consumption and too-strong atomi-
sation of the spray fluid.
– The diameter of the hose for the supply of atomiser air must be 8/10.
– Too-low air pressure produces an unsatisfactory spray pattern.
– Select the lowest possible fluid pressure.
1. Make sure that the control air and atomiser air connections are not reversed.
2. Close the control air (connection "St").
3. "Open" material supply.
Depending on the type of material supply, the "opening" of the material supply is carried out
– By opening the connection tap
– By applying pressure to the storage container
– By filling the material into a storage container (hydrostatic inherent pressure).
4. Open the control air.
The fluid is sprayed. Generally, the adjustment of the spray pattern is now required (
ð
Ä
Chapter 6.4 ‘Adjusting the spray pattern’ on page 23).
6.4 Adjusting the spray pattern
Air and fluid nozzles are available in various sizes. There are 4 different families:
n Round jet – cone-shaped jet in front of the nozzle.
n Flat jet – width-adjustable jet for flat-shaped application. Depending on the design, flat jet
nozzles can be adjusted to adapt steplessly to the work piece geometry or in 45° increments.
Adjust the spray pattern with the following measures:
n Change the atomiser air pressure.
n Change the pressure of the spray fluid.
n Select another nozzle size.
n Adjust the needle stroke (optional) (
setting’ on page 26).

Excessive air pressure causes unnecessarily high air consumption and excessive atomisation
of the spray fluid. It is recommended that you first adjust the spray pattern by varying the air
and spray fluid pressure. If you cannot achieve satisfactory results this way, you should
experiment with other nozzle sizes.
To reduce overspray and the concentration of harmful substances when coating, observe the following points:
n Guide the spray jet vertically to the surface
n Adjust the spray jet to suit the geometry of the work piece
n The spray gun should be as close to the work piece as possible
n Always spray in the extraction direction

Fig. 6: Adjusting the spray pattern
1. Open the adjusting nut ( Fig. 6/3) of the needle stroke adjustment maximum 5.5 mm. To do
so, turn the adjusting nut anti-clockwise.
2. Completely close the flat jet regulator ( Fig. 6/1).
3. Completely open the round jet control ( Fig. 6/2).
Do not close the round jet control completely during operation.
4. Adjust the flat jet on the flat jet regulator ( Fig. 6/1).
5. Continue adjusting settings on the regulators ( Fig. 6/1 and 2) until the desired spray pat-
tern is achieved.
200-0383
It is recommended that you only adjust the spray pattern with the regulators ( Fig. 6/1
and 2). The fluid quantity should only be changed if the desired spray pattern cannot
be adjusted with the regulators ( Fig. 6/1 and 2). A limited fine adjustment, e.g. for the
adjustment of several spray guns in a system, can be made using the adjustment nut (
Fig. 6/3).
In order to obtain reproducible settings, the zero point should be checked and if necessary set after each maintenance ( Ä Chapter 6.5 ‘Setting the zero point of the needle
stroke setting’ on page 26).

CAUTION!
Risk of injury due to sharp edges!
Sharp edges and pointed corners can cause abrasions and cuts on the skin.
Note:
– Proceed cautiously when working on or near sharp edges and pointed corners.
– Wear protective gloves, if in doubt.
7.1 Maintenance schedule
The following sections describe the maintenance work that is required for optimal and fault-free
operation of the device. Check wearing parts such as seals, nozzles and needles at regular intervals. The level of wear depends on the abrasiveness of the spray fluid used. Escaping air and
spray fluid as well as the deterioration of the spray pattern are signs that parts are worn. In case of
questions about maintenance work and intervals, contact the manufacturer; see contact information on the last page.
