Spraying technique

To inactivate the security function, enter
i
"1111" at the "Enter New Code Number"
screen (this is the default code that leaves the
sprayer unlocked). As a result, the Main
Screen will appear at sprayer startup.
Prime Screen
The Prime screen appears
when the pressure control knob
is set at the "Min" setting in the
yellow zone.
Clean Screen
The Clean screen appears
when the pressure control knob
is set at the CLEAN position in
the blue zone and the relief valve is in the PRIME position.
If there is no action at any menu screen for 30
i
seconds, the display will go back to the Main
Screen.
5. Spraying technique
Move the spray gun evenly during the spraying process. Other-
wise the spray pattern will be uneven. Carry out the spray
movement with the arm, not with the wrist. Observe a parallel
distance of approx. 30 cm between the spray gun and the ob-
ject of spraying. The lateral edge of the spray jet should not be
too distinct. The spray edge should be gradual in order to facili-
tate overlapping of the next coat. Always move the spray gun
parallel and at an angle of 90° to the surface to be coated in or-
der to minimize the paint mist.
If very sharp edges result or if there are
i
streaks in the spray jet – increase the operat-
ing 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-pres-
sure hose. Replace any damaged high-
pressure hose immediately.
Never repair defective high-pressure hoses
Danger
yourself!

6.1 High-pressure hose

The unit is equipped with a high-pressure hose specially suited
for piston pumps.

Interruption of work

1. Open the relief valve, valve position PRIME
(k circulation).
2. Switch the unit OFF.
3. Turn the pressure control knob into the white zone (no
pressure generation).
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 45, Section
13.2.
If a non-standard tip is installed, proceed according to the
relevant operating manual.
7. Leave the suction tube and return hose immersed in the
coating material or immerse it into a corresponding
cleaning agent.
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.
Attention

Cleaning the unit (shutting down)

A clean state is the best method of ensuring operation without
problems. After you have finished spraying, clean the unit.
Under no circumstances may any remaining coating material
dry and harden in the unit.
The cleaning agent used for cleaning (only with an ignition
point above 21 °C) must be suitable for the coating material
used.
• Secure the spray gun, refer to the operating manual of
the spray gun.
Clean and remove tip.
For a standard tip, refer to Page 45, Section 13.2.
If a non-standard tip is installed, proceed according to the
relevant operating manual.
1. Remove the suction tube and return hose from the coating
material.
2. Close the relief valve, valve position SPRAY (p spray).
3. Switch the unit ON.
4. Pull the trigger of the spray gun in order to pump the
remaining coating material from the suction tube, high-
pressure hose and the spray gun into an open container.
The container must be earthed in case of
coating materials which contain solvents.
Attention
Caution! Do not pump or spray into a con-
tainer with a small opening (bunghole)!
Refer to the safety regulations.
Danger
5. Immerse the suction tube with the return hose into a
container with cleaning agent.
6. Turn the pressure control knob into the blue zone -
pulsating pressure for unit cleaning.
7. Open the relief valve, valve position PRIME
(k circulation).
8. Pump a suitable cleaning agent in the circuit for a few
minutes.
9. Close the relief valve, valve position SPRAY (p spray).
10. Pull the trigger of the spray gun.
11. Pump the remaining cleaning agent into an open container
until the unit is empty.
12. Switch the unit OFF.
