Handling the high-pressure hose
The unit is equipped with a high-pressure hose specially suited for
piston pumps.
Danger of injury through leaking high-pressure
hose. Replace any damaged high-pressure hose
immediately.
Never repair defective high-pressure hoses yourself!
The high-pressure hose is to be handled with care. Avoid sharp
bends and folds: the smallest bending radius is about 20 cm.
Do not drive over the high-pressure hose. Protect against sharp
objects and edges.
Never pull on the high-pressure hose to move the device.
Make sure that the high-pressure hose cannot twist. This can be
avoided by using a Spray Centre spray gun with a swivel joint and a
hose system.
i
When using the high-pressure hose while working
on scaffolding, it is best to always guide the hose
along the outside of the scaffolding.
i
The risk of damage rises with the age of the high-
pressure hose. Spray Centre recommends replacing
high-pressure hoses after 6 years.
i
use only Spray Centre original-high-pressure
hoses in order to ensure functionality, safety and
durability.

Interruption of work
1. Open the relief valve, valve position PRIME (
k
circulation).
2. Switch the unit OFF.
3. Turn the pressure control knob counterclockwise to minimum
pressure.
4. Pull the trigger of the spray gun in order to release the
pressure from the high-pressure hose and spray gun.
5. Secure the spray gun, refer to the operating manual of the
spray gun.
6. If a standard tip is to be cleaned, see Page 18, Section 12.2.
If a non-standard tip is installed, proceed according to the
relevant operating manual.
7. Depending on the model, leave the suction tube or the
suction hose and return hose immersed in the coating
material or swivel or immerse it into a corresponding cleaning
agent.
Attention
If fast-drying or two-component coating material is
used, ensure that the unit is rinsed with a suitable
cleaning agent within the processing time.

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.
Keep your arm moving at a constant speed and keep 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.
25 - 30 cm
Keep the spray gun at right angles to the surface. This means moving
your entire arm back and forth rather than just flexing your wrist.
Keep the spray gun perpendicular to the surface, otherwise one end
of the pattern will be thicker than the other.
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.
