Using an external power source to start the HP unit can damage the ES2 microprocessor.
When charging the batteries ensure that the emergency stop switch is depressed and
locked. The ES2 microprocessor contains, electronic components that will be damaged if
subjected to excessive voltage of > 36 V.
 To operate the high pressure pump unit with the ES2 microprocessor refer to the ES2 manual.
9.1.2 To start the high pressure pump unit
The jetting operator should have a good foothold and firm control of the jetting tool but
with the trigger(s) in the “OFF” position.
High Pressure water is a highly effective cutting tool and therefore dangerous!
Never point a pistol, lance etc. at other personnel under any circumstances even if
unpressurised!
Under no circumstances even if unpressurised!
 Open water supply to the pump.
 Check the water admission pressure (min. 3 bar) and

Release the emergency stop button .
 Press keypad (Softkey activates) again to activate diesel pre-heat. Pre heat period ends after 15
secs. or when the engine starts. During this period the display will indicate:
 Pre-heat time elapsing from 15 to 0 secs.
 Battery voltage min. 24 V
It is possible to repeat the pre-heat period by pressing (Softkey ) once again.
 Press keypad . The starter is automatically switched off if the engine has started.
 Depending on operational mode (set in factory) the display will indicate:
 pressure
 Diesel idle r.p.m.
 Battery voltage and fuel volume (%)
The pump unit must be switched off and all lines depressurised before attempting to check
hose connections and leakage points!

Observe the oil pressure!
 At 2 bar min. oil pressure turn the high pressure water on.
 Check previously values (r.p.m. or pressure dependent of the control). If necessary adjust the values (ref. to
the ES2 manual).
 Press keypad .
 Depress and lock emergency stop button .
 Turn off the water supply.
 Lower and lock sound proof cover.
