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 remain-
ing coating material dry and harden in the unit.
The cleaning agent used for cleaning (only with an igni-
tion 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.
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
circu-
lation).
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.
Caution! Do not pump or spray into a
container with a small opening (bung-
hole)!
Refer to the safety regulations.
Danger
The container must be earthed in case of
coating materials which contain solvents.
Attention
If fast-drying or two-component coating
material is used, ensure that the unit is
rinsed with a suitable cleaning agent with-
in the processing time.
Attention
Spraying technique
Cleaning the unit (shutting down)
5. Spraying technique
Move the spray gun evenly during the spraying process.
Otherwise the spray pattern will be uneven. Carry out the
spray movement with the arm, not with the wrist. Ob-
serve a parallel distance of approx. 30 cm between the
spray gun and the object of spraying. The lateral edge of
the spray jet should not be too distinct. The spray edge
should be gradual in order to facilitate overlapping of the
next coat. Always move the spray gun parallel and at an
angle of 90° to the surface to be coated in order to mini-
mize the paint mist.

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.
6.1
High-pressure hose
The unit is equipped with a high-pressure hose specially
suited for piston pumps.
7.
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, Sec-
tion 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 correspond-
ing cleaning agent.
Only use WAGNER original-high-pressure
hoses in order to ensure functionality, safety
and durability.
i
Danger of injury through leaking high-
pressure hose. Replace any damaged
high-pressure hose immediately.
Never repair defective high-pressure
hoses yourself!
Danger
If very sharp edges result or if there are
streaks in the spray jet – increase the operat-
ing pressure or dilute the coating material.
