5. Spraying technique
Injection hazard. Do not spray without the tip
guard in place. NEVER trigger the gun unless
the tip is completely turned to either the spray
or the unclog position. ALWAYS engage the
gun trigger lock before removing, replacing or
cleaning tip.
The key to a good paint job is an even coating over the entire
surface.Keepyourarmmovingataconstantspeedandkeep
the spray gun at a constant distance from the surface. The best
spraying distance is 25 to 30 cm between the spray tip and the
surface.

Trigger gun after starting the stroke. Release the trigger before
ending the stroke. The spray gun should be moving when the
trigger is pulled and released. Overlap each stroke by about
30%. This will ensure an even coating.

If very sharp edges result or if there are streaks
in the spray jet – increase the operating pressure
or dilute the coating material.
6. Handling the high-pressure hose
Avoid sharp bending or kinking of the high-pressure hose. The
smallest bending radius amounts to about 20 cm.
Do not drive over the high-pressure hose. Protect against sharp
objects and edges.
Danger of injury through leaking high-pressure
hose. Replace any damaged high-pressure hose
immediately.
Never repair defective high-pressure hoses
yourself!
