Working with the high pressure noz-
zle
The spray angle is essential for the ef-
fectiveness of the high pressure ray.
Normally work is performed with a 25°
flat ray nozzle (included).
Recommended nozzles are deliverable
as accessories
– For strong contaminations
0° full ray - nozzle
– For sensitive surfaces and light con-
taminations
40° flat ray - nozzle
– For thick layered, persistent contam-
inations
Dirt grinder
– Nozzle with adjustable spray angle,
for adaption to different cleaning
