In the version KS-2, the coating substance can be circulated through the head section.
Circulation connection is recommended, for example, when using coating substances
which have a tendency to settle or materials whose temperature has to be kept constant.
A swivel-type material connection facilitates handling of the spray gun, as the
hose/hoses do not have to be turned when the user turns the gun.

Preparations
>
Push the safety catch (29) forward and make sure that the trigger (22 or 25) can
no longer be activated.
>
If necessary, install a suitable spring (19) for 25MPa
>
Install the material nozzle (102)
>
Earth the spray gun
>
Connect the pressure hose to the material connection (27) - or, in the case of
circulation connection, connect both pressure hoses to the material connections (27)
>
Prepare the coating substance and the accessories for material feed
>
Switch on the material pump
>
Set the material pressure on the regulator or on the material pump or in the return
section of the circulation line
>
Open the shutoff valve at the material source
No material should be discharged at any point.

>
after securing the gun using the safety catch (push forwards),
>
change the nozzle (see Krautzberger GmbH order catalogue for available airless
nozzles)
>
If necessary, loosen the nozzle nut (1) again
>
Turn the material nozzle (102) in the desired direction (it can be rotated by 360°)
>
Tighten the nozzle nut (1)
>
Push the safety catch (29) upwards (unlock)
>
Guide the spray jet across the workpiece using even movements
>
Terminate spraying by releasing the trigger (22 or 25)

Notes
Only use accessories from Krautzberger GmbH!
Only use sufficiently sturdy hoses! Check (and, if necessary, replace) older hoses before
starting up the spray gun.
