9.1 Start up
The HDP 502 / S 1100-50 is fully automatic and once the desired pressure has been set controlled entirely by
electronic signal from the accessory.
When the trigger(s) is/are disengaged the engine speed will automatically drop to idle r.p.m. With the accessory
trigger(s) engaged the engine speed will automatically increase from idle to a speed necessary to provide the
required pressure.
Safety regulations demand that a unit should never be operated above its stated maximum operating pressure.
Ref. to machine card or pump name plate for the max. operating pressure. Never exceed
the max. operating pressure
In the case of accident, equipment failure or leakage operate the emergency stop button
immediately.
9.1.1 Warm up and system checks
It is necessary to run the pump and make some system checks before fitting the accessory.
 Check the pump oil level and top up if necessary. The oil level should not be below
the minimum shown on the dip stick.
 Also check if there is water i the oil (emulsion). If found determine and dispose of
the cause. Then change the oil and start (see section "Maintenance", paragraph "oil
change")
 On diesel driven units: Check the oil level of the diesel engine and top up if
necessary.
 Check the condition of the filter housing and inlet. If dirty clean the filter housing and
fit new filter cartridge.
At start up:
Under high pressure the high pressure hose shortens. Ensure the control over the
consumer (i.e. spray gun). A spray gun that lies on the floor can jump up and break when
falling down again.
 Unlock and open control panel door.
 If existing, activate battery switch
 Unlock and ensure that the emergency stop button is released. If necessary unlock the emergency stop
button with the key.
 Press keypad to activate the basic display. Basic display appears. Ensure that it shows:
 pressure is indicated as zero on the left of display (

30 bar tolerance of display – ref. to the ES2 manual.
 r.p.m. are displayed as zero on the left of display,
 voltage and
 the fuel gauge (Tank %) on the right of display indicates that there is sufficient fuel.
 Use branded grade of diesel with less than 0,5 % sulphur content. Ensure that cleanliness is observed when
filling.
Non observance could alter oil change intervals.
There is no “low fuel“ cut-out. Fuel display should be checked regularly.
