New Unit Information
- Mount shut-off valve with testing pressure
gauge on high-pressure outlet (see page 8
step 1, 2), set servopress handgun to max.
water volume, set three-way nozzle to 0° pencil
jet and operate the unit.
- Measure operating pressure and flow rate
(see technical data).
- Adjust engine r.p.m. with adjusting screw (3)
so that max. operating pressure (see
technical data) at testing pressure gauge is
achieved. With this operating pressure the
corresponding operating speed must also be
achieved (see technical data).
- Close and open servopress handgun several
times and check the adjustment. When the
handgun is closed, the pump pressure
decreases (circulation operation) and the
engine r.p.m. reduces.
- Finally seal screws (3), (5) and (13) with safety
paint.
