Taking The Unit Into Operation With Coating Material; Spraying Technique; Handling The High-Pressure Hose; High-Pressure Hose - WAGNER ProSpray 21 Betriebsanleitung

Starting operation
4.6. Taking the unit into operation with
coating material
1. Immerse suction hose (Fig. 6, Pos. 1) and return hose
(2) into the coating material container.
2. Turn the pressure regulator knob (3) in the yellow zo-
ne to minimum pressure.
3. Open the relief valve (4), valve position PRIME
(k circulation).
4. Switch the unit (5) ON.
5. Wait until the coating material exudes from the return
hose.
6. Close the relief valve, valve position SPRAY
(p spray).
7. Trigger the spray gun several times and spray into a
collecting container until the coating material exits the
spray gun without interruption.
8. Increase the pressure by slowly turning up the pres-
sure regulator knob.
Check the spray pattern and increase the pressure
until the atomization is correct.
Always turn the pressure regulator knob to the lowest
setting with good atomization.
9. The unit is ready to spray.

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. Obser-
ve 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.
If very sharp edges result or if there are stre-
i
aks 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 ho-
se. 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
Danger
hoses yourself!

6.1 High-pressure hose

The unit is equipped with a high-pressure hose specially
suited for piston pumps.
Only use WAGNER original-high-pressure
i
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 regulator knob into the black zone
until it stops (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 suction hose and return hose immersed in coa-
ting material or immerse them into a corresponding
cleaning agent.
If fast-drying or two-component coa-
ting material is used, ensure that the
unit is rinsed with a suitable cleaning
agent within the processing time.
