Monitoring during operation
7.3 Monitoring during operation
All operating elements must always be within reach of the operating per-
sonnel.
► During operation, constantly monitor the displays and warnings on the
operating elements.
► Continuously monitor critical operating states and fill levels of the op-
erating materials.
When a danger, a warning signal or an indication occurs on the operating
element:
► The operating personnel must take initiate appropriate measures to
avoid damage.
► If abnormal noises occur shut down the device, if possible, to prevent
damage.
The highest pressure of the water pump, read from the pressure gauge, is
17 bar (246 psi). The maximum feed pressure (supply pressure), read on
the pressure vacuum gauge, is 17 bar (246 psi).
The supply pressure, read on the pressure vacuum gauge, must not drop
below 1 to 2 bar (15 to 30 psi), otherwise a cross-sectional constriction of
the hose will occur and the water supply will be interrupted.
If the limit pressure of 17 bar (246 psi) is exceeded during operation, the
portable pump automatically reduces the engine speed and thus the pump
pressure. The discharge pressure is limited to maximum 17 bar (246 psi).
This prevents the hose from bursting. If the discharge pressure drops
again, the speed is again increased automatically.
Due to the electronic control, it is possible to exceed the limit pressure for
a short time.
7.4 Preparation for startup
The sequence of the described processes is to be maintained without ex-
ception!
Before each start-up it should be checked that all operating materials (oil
etc.) are full.
► Carry out complete visual checks.
► Check all relevant indicators and instruments for function and condi-
tion.
► Fill the fuel tank.
For further information refer to Chapter "Refuel".
► Check the cleanliness of the suction filter in the External drafting water
connection.
► Wear personal protection equipment.
For further information refer to Chapter "Service and cleaning".
