ENGLISH
gun KAA-1300 must always be operated using filtered
air.
Adjusting the nozzle
The nozzle can be steplessly rotated by 360°
in the axis of the spray jet and secured in any
position. To do this,
loosen (but do not remove) the nozzle nut
(1; 114)
turn the material nozzle (112) to the desired
position
tighten the nozzle nut (1; 114)
The automatic spray gun is now ready for use.
STARTUP
Open material feed
Open control air supply
The coating substance is sprayed.
i
It is generally not possible to change the spray profile
of airless units by adjusting the nozzle. If a different
spray profile is desired, you must change the airless
nozzle. Rinse the automatic spray gun through with
detergent prior to first startup!
i
The spray profile depends on, among other factors,
the viscosity of the coating substance and can be alte-
red via the material pressure. If changing the material
pressure does not create an optimum spray profile, it is
advisable to repeat the trial using a different material
nozzle.
(!) DANGER
WHEN CHANGING THE AIRLESS NOZZLES, IT IS
ESSENTIAL THAT YOU CLOSE NOT ONLY THE CON-
TROL AIR SUPPLY BUT ALSO THE MATERIAL FEED!
ALTHOUGH NO MATERIAL CAN ESCAPE FROM THE
VALVE SEAT SCREW (3) WHEN THE CONTROL AIR
SUPPLY IS CLOSED, ACCIDENTAL (OR OTHER) OPE-
NING OF THE CONTROL AIR SUPPLY DURING NOZZ-
LE CHANGING CAN RESULT IN DANGER TO LIFE
AND LIMB OF ALL PERSONS IN THE AREA OF THE
UNIT. IN SUCH AN EVENT, THE MATERIAL JET IS
DISCHARGED FROM THE FRONT OPENING OF THE
VALVE SEAT SCREW (3) AT HIGH SPEED. THE JET
CAN PENETRATE THE SKIN, ENTER THE BODY AND
FORCE AIR INTO THE ORGANISM. RISK OF FATAL
EMBOLISM! THERE IS ALSO THE RISK OF POISO-
NING WHEN USING POISONOUS COATING SUB-
STANCES OR DETERGENTS!
INTERRUPTIONS TO
OPERATION, WORK
BREAKS
Close material feed and - as soon as material
is no longer discharged -
Close the control air supply
FINISHING WORK
Close material feed and - as soon as material is no
longer discharged -
close the control air supply
Pump detergent through the hoses and the automa-
tic spray gun until it is discharged clear
Briefly open the control air supply so that the materi-
al nozzle is also rinsed through with detergent
Close the shutoff valve on the pump
Switch off the material pump
Close the control air supply at source
