New Unit Information
Basic setting: overflow valve
1 Shut-off valve
2 Testing pressure gauge
3 High-pressure outlet
4 Adjusting nut with locking nut
5 Overflow valve spindle
6 Water inlet
Note:
Before any adjustments check the high-
pressure nozzle and the air filter for
damage or wear. All defective parts must
be replaced.
- Mount testing pressure gauge (2), shut-off
valve (1), high-pressure hose and servopress
handgun without high-pressure nozzle on high-
pressure outlet (3). The unit pressure gauge is
not to be used to check the operating pressure
because it measures too inaccurate !
- Set servopress handgun to max. water volume,
open it and operate the unit.
- Close shut-off valve (1) slowly until low pressure
flow rate has been achieved (see technical
data). This corresponds to the smallest
servopress setting. Measure flow rate and
compare it with technical data.
- Adjust max. operating pressure with adjusting
nut (4) (see technical data) and check with
testing pressure gauge (2):
Increase spring tension: operating pressure
increases.
Decrease spring tension: operating pressure
decreases.
- Mount servopress handgun with new high-
pressure nozzle (see technical data) and open
again shut-off valve (1) completely. Close and
open servopress handgun several times. Check
max. flow rate and max. operating pressure
during high pressure.
- Set servopress handgun to min. water volume
(low pressure operation) to check and check
low pressure flow rate. If required repeat the
above mentioned steps.
- Finally secure the adjusting nut (4) with locking
nut and seal with safety paint.
