ENGLISH
POWERED SPRAY JET IS POWERFUL ENOUGH TO
CAUSE PARTS OF THE WORKPIECE OR SURFACE
TO FLY AROUND IN THE WORKING ZONE.
DURING SPRAYING AND DUE TO REBOUND OFF
THE WORKPIECE, COATING MATERIAL IS DISCHAR-
GED INTO THE SURROUNDING ATMOSPHERE.
DEPENDING ON THE COATING MATERIAL USED,
THIS CAN RESULT IN ENVIRONMENTAL HAZARDS,
FIRE
AND
EXPLOSION
RISK,
AND
HEALTH
HAZARDS. FOR THIS REASON, ONLY USE SPRAY-
ING
EQUIPMENT
IN
SPECIALLY
DESIGNATED
AREAS! ONLY WORK IN ADEQUATELY VENTILATED
AREAS! IF NECESSARY, USE SUITABLE EXTRACTI-
ON SYSTEMS!
ENSURE ADEQUATE EARTHING (E.G. CONNECTION
OF BUILDING EARTH TO THE RETAINING BOLT
(108))!
RADIATORS OR WATER PIPES DO NOT PROVIDE
SUFFICIENT EARTH CONTACT!
DURING BREAKS IN OPERATION OR WHEN SHUT-
TING DOWN THE EQUIPMENT AS WELL AS PRIOR
TO DISMANTLING OR THE START OF REPAIR AND
MAINTENANCE WORK, YOU SHOULD ENSURE THAT
THE AUTOMATIC SPRAY GUN IS NO LONGER
UNDER PRESSURE (CLOSE MATERIAL FEED, OPEN
CONTROL AIR UNTIL MATERIAL PRESSURE HAS
DISSIPATED, CLOSE CONTROL AIR SUPPLY)!
CHECK CONNECTIONS AND WEARING PARTS AT
APPROPRIATE
INTERVALS
AND
REPLACE
IF
NECESSARY! CHECK FOR MATERIAL FATIGUE AT
REGULAR INTERVALS! PRIOR TO EACH REPEAT
STARTUP, CHECK CONNECTIONS, HOSES AND SET-
TINGS AND MONITOR THE AUTOMATIC SPRAY GUN
FOR SEAL TIGHTNESS (NO UNCONTROLLED AIR
DISCHARGE,
NO
UNCONTROLLED
MATERIAL
DISCHARGE WHEN CONTROL AIR IS CLOSED)!
ALWAYS ROUTE HOSE LINES IN SUCH A WAY THAT
THEY CANNOT BE DAMAGED, STUCK OR DRIVEN
OVER. AVOID EXCESSIVE TENSION OR BENDING
STRAIN! IF HOSES ARE DAMAGED OR LEAKY, SHUT
DOWN THE SYSTEM IMMEDIATELY AND REPLACE
THE HOSES!
ALWAYS SECURE HOSE CONNECTIONS IN SUCH A
WAY THAT UNCONTROLLED MOVEMENT OF THE
HOSE ENDS IS AVOIDED IF THEY ARE ACCIDENTAL-
LY DISCONNECTED. IF NECESSARY, USE CLIPS TO
SECURE THE HOSE ENDS.
ONLY USE SPARE PARTS AND ACCESSORIES FROM
KRAUTZBERGER GMBH! KRAUTZBERGER GMBH
ASSUMES NO LIABILITY FOR DAMAGE IF ANY
EXTERNAL PARTS ARE USED.
ADHERE TO THE PRESSURES AND TEMPERATURES
LISTED UNDER “TECHNICAL
DATA”!
WHEN WORKING AT TEMPERATURES ABOVE 43°C,
ATTACH PROTECTIVE DEVICES AND POST NOTIFI-
CATION CONCERNING THE RISK OF COMBUSTION
DUE TO COATING SUBSTANCE, AND DRAW PARTI-
CULAR ATTENTION TO RISKS RESULTING FROM
LEAKAGE OR BURSTING OF THE SPRAY GUN!
ENSURE THAT NEITHER SPRAYING NOR MATERIAL
DISCHARGE CAN BE ACTIVATED ACCIDENTALLY OR
BY DEFECTS IN THE UNIT AS LONG AS ONE OR
MORE PERSONS ARE IN THE HAZARD ZONE.
TAKE STEPS TO ENSURE THAT NO ALTERATIONS
CAN OCCUR OR BE MADE TO THE CONTROL AIR
FEED OR THE MATERIAL PRESSURE DURING SET-
TING AND MAINTENANCE WORK WITHOUT THE
KNOWLEDGE OR CONSENT OF THE SETUP TECH-
NICIAN!
USE FOR INTENDED PURPOSE
The automatic spray gun type KAA-1300 is designed to
allow automatic (not manual) coating of metal, plastic,
ceramics, wood and other suitable surfaces. Typical
coating substances are, for example, lacquers, paints,
water-soluble lacquer systems, adhesives, oil, release
agents etc. It is also suitable for the application of abra-
sive materials at operating pressures below 5 MPa (50
bar). The automatic spray gun works on the airless prin-
ciple - in other words, the spray jet is generated exclu-
sively by the material pressure pressing the material
through a nozzle. After being discharged from the noz-
zle, the spray jet takes on the shape dictated by the noz-
zle. It is then directed at the workpiece. The effective
spray jet is not quite as wide as theoretically possible.
The particles of the spray jet reach far higher speeds
than with pneumatically operated spray guns. The mate-
rial throughput is correspondingly higher and the jet more
concentrated (in other words, the “swirling zone” is small-
er). The size and shape of the jet can only be changed
by changing the nozzle. The diameter of the nozzle bore-
hole determines the material flow volume. The size and
geometry of the (always) elliptically shaped nozzle open-
ing determine the height and width of the jet (shape of
an elliptical cone). A wide range of airless nozzles are
available and can be obtained from Krautzberger GmbH.
The nozzle can be rotated steplessly by 360° in the axis
of the spray jet and secured in any position. This allows
optimum adjustment of the angle at which the jet hits the
workpiece to the respective conditions.
