Pour in fuel
z
The fuel low pressure system must be vented be-
fore the first start-up after filling with the manualy
supply pump.
Only use clean commercially available brand diesel
fuel. Observe fuel quality (
36
).
Use summer or winter-grade fuel, depending on the
ambient temperature.
Only re-fuel when the engine is not running.
Ensure cleanliness.
Do not spill fuel.
Additional venting of the fuel system by a 5
minute trial run at idle speed or on low load
is absolutely essential.
Filling the coolant system
z
Connect coolant outlet (2) and coolant inlet (1) to
the cooling system. Connect the feed line of the
compensation tank to the coolant pump or to the
coolant inlet line (2).
z
Connect ventilation line from the engine and, if
necessary, from the cooler to the compensation
tank.
z
Fill cooling system via the compensation tank.
z
Close compensation tank with valve.
The coolant must have a prescribed con-
centration of cooling system corrosion pro-
tection agent.
Never operate the engine without coolant,
even for a short time!
Order coolant corrosion protection agent
from your DEUTZ partner.
z
Start the engine and run up until the thermostat
opens (line (2) heats up).
z
Engine operation with open thermostat 2 - 3 min-
utes.
z
Check the coolant level in the compensation tank
and top up coolant if necessary.
z
If required, repeat procedure with engine start.
z
Fill up coolant to the MAX mark on the compen-
sation tank and close the cooling system cap.
z
Switch on any available heating and set to the
highest level so that the heating circuit is filled
and vented.
z
Observe the filling volume of the cooling system
(
70
).
z
If required, repeat procedure with engine start.
Trial run
Carry out a brief trial run up to operating temperature
(approx. 90 °C) after preparations.
Do not load the engine if possible.
z
Work with the engine not running:
–
Check engine for tightness.
–
Check the lubricating oil level and top up lu-
bricating oil if necessary.
–
Check the coolant level and top up coolant if
necessary.
z
Work during the trial run:
–
Check engine for tightness.
Venting of the fuel system by operating for
5 minutes on no load or with low load is ab-
solutely essential.
