Adjustment of cut off pressure
Fig.G.1: Pressure regulation
* Note ! The operating pressure is measured in the valve block at the manufacturing site, thus the
actual pressure at the high pressure outlet will bee slightly reduced at nominel water flow because
of the injector. Refer to data sheets section ”B” (Pressure @ outlet or pressure @ Gun).
Fig.G.2: Pressure adjustment
1. Install test pressure gauge 1206358 on
machine outlet.
2. Open the regulation fully.
3. Close untill machine has reached the re-
commended working preassure.
4. Close further to check the cut off pressu-
re.
NOTE: Cut off pressure is the when the
machine turns from working
pressure to by-pass mode.
• The cut off pressure is adjusted on the water
regulation.
• Use a 3mm allen key and a 10mm spanner.
• Loosen the 10mm counter nut and turn the
allen key clockwise to increase the cut off
pressure.
• Turn the allen key counter clockwise to
reduce the cut off pressure.
NOTE: Find the right cut off pressure in the
technical data Chapter A.
