Hand-held Spray Gun KS 5K
ENGLISH
1 Function and identification
1.1 Function
The material squeeze spray gun KS 5K with cannulate thread is especially well-suited for the processing of highly viscose coating materials such as glue, adhesives, sealing agents or grease.
The nozzle screw has an M8x1 exterior thread onto which e. g. a flexible cannula can be screwed
on to apply the coating material even to places that are difficult to access.
The hand-held spray gun operates based on the airless principle, which means the spray jet is
exclusively generated by the fluid pressure, which presses the fluid through a nozzle. After exiting
the nozzle, the spray jet takes the shape specified by the nozzle. It is directed towards the work
piece. The effective spray jet is not quite as wide as theoretically possible.
The coating material that is to be processed is applied to the surface by a person who is manually
guiding the hand-held spray gun over the surface that needs to be coated and who is starting the
spraying process at the respectively intended location by operating the pull lever. The coating
material is fed to the hand-held spray gun in liquid form under high fluid pressure.
The pivotable fluid connection enables the material supply from above or below.
Pulling the pull lever towards the handle of the main element moves the valve needle back against
the resetting force of the valve spring. The valve needle pushes out of the valve seat of the nozzle
screw and thereby releases the material flow.
The volume of the exiting material depends exclusively on the nozzle size and the fluid pressure!
The volume and shape of the jet can only be modified by changing the nozzle. The diameter of the
nozzle bore determines the material flow volume, while the size and geometry of the nozzle
opening determine the height and width of the jet.
The hand-held spray gun features a locking lever and a protection hoop for safe operation.

Ä
Chapter
In contrast to compressed air-operated hand-held spray guns, the spray pattern of airless
devices can by default not be changed through settings on the nozzle. If a different spray pattern is desired, the airless-nozzle must be exchanged.
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
material pressure changes, it is recommended to try again with a different nozzle screw.

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
material pressure changes, it is recommended to try again with a different nozzle screw.
If the fault is not included in the following tables or if it cannot be eliminated with the measures
described, contact Krautzberger Customer Care.
Error Cause Remedy
Unsatisfying spray pattern Nozzle screw possibly dirty Clean nozzle screw and
replace if necessary (
Ä
Chapter 7.6 ‘Replace nozzle
screw and seal’ on page 37).
Insert a material filter in the
material supply line.
