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 condi-
tions.
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 prin-
ciple 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.

1 Function and identification
1.1 Function
The hand-held spray gun Mignon 3 is used for the coating of surfaces with liquid to low-viscose
coating materials. Typical coating materials are: Paints, dyes, adhesives, glazes, enamels,
debonding agents.
The coating material is fed to the hand-held spray gun either under pressure (fluid pressure pumps
or pressurised fluid containers to process large quantities of coating material) or through attached
gravity feed cups or suction cups (for smaller quantities).
Begin spraying process by pulling the trigger. The spraying process is terminated by releasing the
trigger.
The coating material is atomised using compressed air.
The geometry of the spray jet and the sprayed quantity of the coating material can be adjusted:
nSelection of various air and fluid nozzles
nChanging of the atomiser air pressure
nChanging of the coating material pressure
nAdjustment of the needle stroke on the regulator of the hand-held spray gun
nAdjustment of the flat jet regulator on the hand-held spray gun
The hand-held spray gun Mignon 3 is available in different designs:
Supply of coating material:
nvia attached gravity feed cups or suction cups holding from 65 to 300 ml
nvia hose lines on the gun handle
nvia hose lines on the head section
The hand-held spray gun consists of the following materials: Aluminium (head section), stainless
steel (needle and nozzle) as well as brass and plastic (seals).
Gravity feed cups and suction cups are made of aluminium, copper or plastic.
Before starting up the hand-held spray gun, check the compatibility of the device materials
with the coating materials that are used!

3 Safety and responsibility
3.1 General safety instructions
WARNING!
Risk of death, risk of injury or property damage due to hazardous media!
Potential consequences: The application of hazardous media can lead to death, severe inju-
ries or property damage.
When handling hazardous substances, ensure that the current safety data sheets of the haz-
ardous substance manufacturer are available. The necessary measures can be derived from
the content of the safety data sheet. Since the hazardous potential of a material can be reas-
sessed at any time due to new lessons learned, the safety data sheet must be checked regu-
larly and replaced if necessary.
The system owner is responsible for the presence and the up-to-date status of the safety data
sheet and the associated generation of the risk assessment of the effected workstations.
CAUTION!
Risk of injury caused by compressed air!
Uncontrolled leaks of compressed air can lead to serious injuries.
Note:
– Prior to any work on the device/machine, all compressed-air lines must be closed and
disconnected.
– Never point compressed air at living beings.
WARNING!
Sound pressure level
Depending on the operating conditions, the sound pressure of the device may cause hearing
damage.
Take suitable action to reduce the impact of the existing sound pressure level. The owner is
responsible for the type and implementation of suitable measures, which may depend on the
local conditions.

Personnel:
nUser
nSpecialised personnel
Protective equipment:
The selection of the personal protective equipment depends on the utilised medium of the system
owner. The information provided by the medium manufacturer indicated on the safety data sheet
must be adhered to in order to ensure the proper selection of personal protective equipment.
WARNING!
Risk of death, risk of injury or property damage due to hazardous media!
Potential consequences: The application of hazardous media can lead to death, severe inju-
ries or property damage.
When handling hazardous substances, ensure that the current safety data sheets of the haz-
ardous substance manufacturer are available. The necessary measures can be derived from

WARNING!
Risk of fatal injury, risk of injury or property damage due to damaged or disconnected
lines!
Damaged or disconnected lines can cause death, serious injuries or property damage due to
whip-like movements and the spraying of fluids.
Note:
– Check the fluid pressure lines for damage and a tight fit prior to every work process.
7.2 General information about start-up / commissioning
Adhere to the following general information for commissioning:
nOnly carry out the installation and commissioning of the hand-held spray gun in accordance
with the steps described in this operating manual.
nCheck the material and compressed air hose lines for damage and tight fit before each use.
nAlways observe the applicable country-specific safety, accident prevention, occupational
safety, and environmental protection regulations applicable for the area of use for the hand-
held spray gun.
nDo not use sharply abrasive, chemically aggressive, very hot or very cold spray media without
first consulting with and receiving approval from Krautzberger GmbH.
nAdhere to the safety data sheets of the spray media manufacturer.
nOnly operate the hand-held spray gun in compliance with the values specified in (
Ä Chapter
13 ‘Technical data’ on page 55).
nNever point the compressed air or the spray jet at living beings.
nOnly use sufficiently sturdy hoses! Check and, if necessary, replace older hoses before
starting up the hand-held spray gun.
nOnly use hoses that match the hose connections and check them for their proper seat and
ensure that they are leak-proof.
nIt is recommended to flush the hand-held spray gun prior to commissioning using a suitable
cleaning product (spraying process with cleaning product, until it runs clear when exiting).
nTo ensure that there are no particles clogging the nozzles, we recommend to clean the
coating material with a material filter positioned in front of the fluid connection (high pressure
material filters can be purchased from Krautzberger GmbH).
nTo achieve a unified coating thickness and spray pattern for high-quality coatings, a cross-
coating process is recommended, which means that the area is first coated in horizontal lines
and then in vertical lines.
Among other factors, the spray pattern depends on the viscosity of the coating material. It can
be modified through the fluid pressure. If the optimal application cannot be achieved through
fluid pressure changes, it is recommended to try again with a different fluid nozzle.
