Translation of the original operating instructions
Thank you for selecting a Krautzberger product.
This product has been manufactured following state-of-the-art manufacturing procedures and
extensive quality assurance measures. We promise you a product of the highest quality.
If you have questions, requests or suggestions, please contact us. We are always glad to assist

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.

Automatic spray gun M -10
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, glazes, enamels, 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.
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.
Upon opening the control, the control piston charged with compressed air first opens the atomizer
air valve and then with a short delay the fluid nozzle of the spray gun. Upon closing the control,
first the fluid nozzle and then the air nozzle is closed in order to prevent a subsequent dripping of
the spray fluid.
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 atomisation 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 consists of the following materials:
Component Material
Head section Stainless steel or anodised aluminium
Control section Aluminium anodised
Main element
Needle Stainless steel
Nozzle
Seals Various plastics

Changing the installation position of the spray gun
The automatic spray gun can be mounted on both sides on the retaining bolts in order to
change the installation position.
Fig. 3: Mounting the automatic spray guns
1. Slide the automatic spray gun ( Fig. 3/1) with the respectively designed drill hole over the
retaining bolt ( Fig. 3/3).
2. Fix retaining bolt with installation screws ( Fig. 3/2).
3. Ensure proper earth connection of the automatic spray gun.
5.5 Connecting the automatic spray gun
See also ( Ä Chapter 5.3 ‘Connection scheme’ on page 17).
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 atomisation air failure. This presents a
hazard to people and property.
– Make sure that the fluid supply and the control air are interrupted if the atomisation air
pressure drops off quickly.
– It is recommended to regulate the atomisation air pressure via a filter pressure reducer.

Note:
– Check the fluid and compressed air lines for damage and a tight fit prior to every work
process.
WARNING!
Risk of injury due to hot surfaces!
The surfaces of components can become very hot during operation. Direct contact with hot
surfaces causes severe skin burns.
– Do no touch hot surfaces during operation, wear protective gloves if necessary.
– Ensure that all surfaces have sufficiently cooled down prior to starting any work.

6.3 Shutting down
6.3.1 Temporary shut-down
End the spray procedure by switching off the control air (connection "St").
The atomiser air (connection "Z") is automatically closed in the automatic spray gun.
6.3.2 Long-term shut-down
1.
Close the air supply for control air and atomiser air (
on page 17).
2. Close the material supply and switch off the pump if necessary.
3.
If necessary, clean the spray gun ( Ä Chapter 7.3 ‘Cleaning’ on page 27).

6.4 Start of operation
1. Switch on the compressed air supply.
2. Where applicable, switch on pump or pressure container for spray fluid.
3. Point automatic spray gun at a test surface.
4. Start spraying process by switching on the control air.
5.
Adjust the spray pattern ( Ä Chapter 6.5 ‘Adjusting the spray pattern’ on page 24).
6. Complete the spraying process by switching off the control air.
7. Direct spray gun towards workpiece.
8. Start spraying process by switching on the control air.
6.5 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.
n Rotary stream – a rotary pulse produces a highly “swirled” spray jet; for difficult workpiece
geometries (angular sections etc.).
n Full-cone rotary stream – a rotary pulse produces a highly “swirled” spray jet; for difficult
workpiece geometries (back cuts, etc.).
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 Adjusting the needle stroke (
Ä
Chapter 6.6 ‘Adjusting the needle stroke’ on page 25).
Too-high air pressure causes unnecessarily high air consumption and too-strong 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.

7.2 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.

standard models. The length, form, and spray angle extensions can be adjusted to customer-specific requirements.
n Seals
– Seals, bats touch the coating material, can be made of stainless steel, copper, fibre,
leather, PA, PE or PTFE.
n Stainless steel model
– Head section made of stainless steel, during the processing of particularly acidic or alka-
line coating material
n Filter
– Filter with mesh sizes of 0.06 - 0.3 mm which prevent the clogging of the fluid nozzle
n Quick, angle and swivel fittings
