Engine coolant change
CAUTION!
Burning hazard from the hot cooling system!
Only carry out maintenance work after the portable fire pump has been
shut down and the cooling system has cooled down.
NOTICE
Missing coolant
The engine can be damaged through faulty or insufficient filling.
Usually no change of coolant is planned. However due to various reasons
it may be necessary to carry out a change, or due to a deficiency a signifi-
cant quantity of coolant may escape.
Filling / changing the coolant
If damage occurs to the cooling system or the engine, this must be fixed be-
fore filling.
If coolant has been completely drained, before a restart of the portable fire
pump, it must be ensured that at least 1.7 - 1.8 l of coolant were added.
If coolant has not been completely drained, before the first start of the por-
table fire pump, it must be ensured that the compensation tank has been
completely filled with coolant (above MAX indicator).
► Put portable fire pump into idling mode and manually extract.
Press the priming pump function switch (S3) for max. 3 mins .
► If the coolant level in the compensation tank drops add coolant.
► Watch the engine temperature, it may not rise above 95°C, if this
should be the case, switch off the portable fire pump and allow it to cool
for 10-15 mins.
► Repeat process untilo 2.5 - 2.7 l of coolant is in the cooling circuit.
If after three-times of repetition still the required 2.5 - 2.7 l is not in
the cooling circuit, contact Rosenbauer customer service or the
nearest Rosenbauer service centre.
► With approx. 2.5 - 2.7 l coolant in the suction state of the portable fire
pump the speed can be increased to approx. 3000 - 3500 rpm, to add
the remaining amount of approx. 3.3 - 3.5 l coolant. Observe engine
temperature while doing so..
