a) Material side: For replacing the self-adjusting paint needle packing,

in stuffing box slightly against the block. Grease air piston rod very
slightly with spray gun grease (pos. 10009) and install it. Mount trigger,
air micrometer and fluid tip.
6. Cleaning and Maintenance
Never use force. Using improper tools such as pipe wrench, gas torch, etc. will void any
warranty. In many cases proper repairs can only be carried out with the aid of special tools. In
such cases, limit yourself to establishing the cause of the problem and leave the repairs to the
service department. We refuse to accept liability for perfect functioning of the spray gun if it is
disassembled by the customer.
a) Flush out the gun thoroughly with thinner or cleaning fluid.
b) Clean the air nozzle with a paint brush or brush. Do not immerse the nozzle in
thinner or cleaning fluid.
c) Under no circumstances try to clean clogged drillings using an unsuitable tool, since
the slightest amount of damage adversely affects the spray pattern. Use SATA nozzle
cleaning needles ((included in cleaning kit 64030).
d) Only remove the black air distribution ring (Order No. 127399 / set of 3) in the gun
head in case it is damaged (no sealing performance at the paint nozzle).
In case of removal, always insert a new air distribution ring to ensure flawless
function. Insert new air distribution ring in its correct position and tighten paint nozzle
again. Respect mounting instructions for the air distribution ring (see 6.1)!
d) Slightly oil movable parts with SATA special grease (order no. 10009).
