Operational Interruptions, Work Breaks - Krautzberger KS-1 Operating Instructions Manual

Only use hoses which fit in the hose connections; ensure correct fit and seal-tightness!
It is advisable to rinse the spray gun through using a suitable detergent prior to first
startup (effect spraying using detergent until it is discharged clear).
To ensure that particles do not block the nozzle, it is advisable to clean the coating
substance through a material filter in front of the material connection (27). High-pressure
material filters are available from Krautzberger GmbH.
In order to achieve uniform layer thickness and spray profile when using high-grade
coatings, it is advisable to apply the substance in cross-wise fashion; in other words, first
coat the surface in horizontal lines and then in vertical lines (or vice-versa).
Material feed is effected via a pump. A circulation connection is recommended, for
example, when using settling coating substances or for materials whose temperature has
to kept constant.
In airless units (unlike pneumatic spray guns), it is generally not possible to change the
spray profile by adjusting the nozzle. If a different spray profile is desired, you must
change the airless nozzle. The spray angle can be altered by using adjustable material
nozzles.
The spray profile depends on, among other factors, the viscosity of the coating
substance and can be altered 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 not only push the safety
catch (29) forwards and check that the lever is blocked on the trigger (22 or 25) but
also that you close the material feed!
Although no material can escape from the valve seat screw (4) when the trigger (22 or
25) is blocked by the safety catch (29), accidental (or other) pressing of the trigger during
nozzle changing can result in danger to life and limb of all persons in the area of the
spray jet. In such an event, the material jet is discharged from the front opening of the
valve seat screw (4) 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 poisoning
when using poisonous coating substances or detergents!
4. Interruptions to operation, work breaks
During operational downtimes - e.g. work breaks:
> Close the shutoff valve at the material source
> Switch off the pump (where applicable)
> Push the safety catch (29) forwards (lock)
