Setting up the P2 E17 Airless Sprayer correctly – for a clean spray pattern & fast cleaning
When an Airless "spits," leaves streaks, or the nozzle constantly clogs, it's almost always due to three things: material flow (suction/priming), pressure buildup (starting cleanly from the minimum), and the cleaning routine. This guide shows you a field-tested process – including guide values, professional workflow, troubleshooting, and maintenance.
Quick Navigation
Product Overview: Applications, Scope of Delivery, Advantages
The P2 E17 is a compact, mobile Airless system for lacquers, glazes, and interior emulsion paints – including a gun, pressure gauge, 7.5 m high-pressure hose, and a standard 517 nozzle. Ideal if you want to get started quickly and value a reproducible spray pattern.
| Topic | Practical Classification |
|---|---|
| Areas of Application | Water- & solvent-based paints/glazes, interior latex/emulsion |
| Not Suitable For | Fillers/putty, facade paints, lye, highly flammable materials |
| Performance (Guide Value) | Up to approx. 1.44 l/min flow rate, up to approx. 207 bar maximum pressure |
| Standard Setup | 517 nozzle (0.017"), hose up to 7.5 m, 1/4" NPS connection |
| Operating Environment | Temperature range approx. 5–40 °C |
KPI
Up to 207 bar
Pressure reserve for a uniform spray pattern – ramp up pressure cleanly from the minimum.
KPI
1.44 l/min
Productive work for typical interior applications (guide value, material dependent).
KPI
30% Overlap
Recommended overlap per pass for even coverage.
Practical Tip: "Pressure as low as possible – as high as necessary"
Always start with minimum pressure and increase slowly until the spray pattern is stable. Too much pressure makes the pattern coarse, increases overspray,
and can unnecessarily "mist" material. If the device struggles with suction: press the inlet valve pusher at the bottom of the pump several times.

Recommended Basic Settings (as Guide Values)
The following settings are deliberately formulated as guide values – fine-tuning may be necessary depending on the material, temperature, and surface. The sequence is important: first prime/bleed correctly, then stabilize the pressure.
- Set up the pump horizontally and check all connections firmly (hose/gauge/output components must be pressure-resistant).
- Set relief/prime valve to "Prime" for filling/bleeding; later to "Spray" for spraying.
- Start pressure regulator at minimum and increase slowly until the spray pattern becomes clean.
- Use the 180° reversing nozzle function: Turn briefly to the cleaning position for filling/rinsing and for quick unclogging.
- Spraying Technique: Guide passes with approx. 30% overlap for uniform coverage.
Pro Workflow: 6 Steps from Bucket to Surface
- Setup & Safety: Place the device horizontally, engage the gun safety (trigger lock), and check all connections. Use personal protective equipment.
- Prepare Suction: Submerge the suction and return hoses into the material container. Set the relief valve to Prime, and the pressure regulator to Prime/Clean or a low setting.
- Prime Material/Bleed Air: Turn on the device. You should see air bubbles until the system is filled. If not: operate the inlet valve pusher at the bottom of the pump.
- Fill the Hose: Set the relief valve to Spray, point the gun into the bucket (nozzle 180° in cleaning position), and trigger briefly until material exits cleanly. Secure the gun again.
- Adjust Spray Pattern: Set nozzle to spray direction, ramp up pressure slowly from minimum, and spray a test area. Goal: a uniform fan without "tails" or streaks.
- Spray Cleanly: Work in passes with approx. 30% overlap, keeping the gun in motion. If clogged: secure gun, turn nozzle 180°, spray briefly to clear, then turn back.
Troubleshooting: 4 Typical Problems – Solved Quickly
1) Motor does not run
- Check power supply and ensure the device is correctly plugged in.
- Do not leave the pressure regulator at minimum: increase pressure slowly until the control system starts cleanly.
2) Pump does not suck material
- Material viscosity too high: Dilute material appropriately (refer to manufacturer data).
- Check suction system/connections for air leaks (leak = drawing air).
- Inlet valve is stuck: Press the inlet valve pusher on the underside of the pump several times.
3) Material does not come out of the gun despite pressure
- Nozzle clogged: Turn nozzle 180°, spray briefly to clear, then turn 180° back and continue working.
- Gun filter clogged: Remove and clean or replace the filter.
4) Unstable spray pattern / fast wear
- Do not let the pump run dry: only for very brief moments – otherwise, premature wear/damage may occur.
- Consistent cleaning routine: Regularly remove and rinse the nozzle, holder, and filters.
Maintenance & Cleaning (5 Points to Save Time)
- Always depressurize before cleaning: Release system pressure via the relief valve (Prime position).
- Use appropriate cleaning medium: Warm water for water-based materials; suitable solvents only according to manufacturer specifications.
- Remove nozzle/holder/filter: Remove parts and clean them thoroughly separately – do not spray cleaning agent "through the nozzle."
- Return line to waste container: When rinsing, lead the return hose into a suitable waste bucket.
- Storage: For longer downtime, add a few drops of machine oil into the designated openings and run briefly (very briefly).
FAQ: Common Practical Questions about the P2 E17
1) Which materials can I process with the P2 E17?
Water- and solvent-based paints/glazes as well as interior latex/emulsions are suitable. It is not intended for fillers/putties, facade paints, lyes, or highly flammable materials.
2) How do I bleed the air correctly if the pump isn't sucking?
Set the relief valve to Prime, place the suction/return lines in the bucket, and start the device. If there is no bubble movement, press the inlet valve pusher on the bottom of the pump several times and check all suction connections for air leaks.
3) Why should I ramp up the pressure from the minimum?
Because it reduces overspray and allows you to stabilize the spray pattern precisely. Too much pressure often makes the result coarse and wastes material.
4) What do I do if the nozzle keeps clogging?
Use the reversing nozzle: secure the gun, turn the nozzle 180°, spray briefly to clear, then turn 180° back. Additionally, check and clean/replace the gun filter.
5) How do I get an even result on large surfaces?
Maintain a constant distance, work briskly, and spray in passes with approx. 30% overlap. Always activate the trigger lock when pausing and depressurize the system in a controlled manner.
Conclusion
With the P2 E17, you get a compact Ready-to-Spray Airless setup that shines especially when you bleed air correctly, build up pressure controlled from the minimum, and consistently use the reversing nozzle plus the Prime/Clean routine. Following the workflow above significantly reduces downtime (nozzle/filter/suction) – and leads to uniform surfaces faster.
