● Trial run
After the engine has been prepared, let it run
for about 10 minutes without load.
During and after trial run
– Check the engine for leaks.
After the engine has been turned off
– Check the oil level, see 6.1.2
If necessary, top up oil, see 3.1.1
– Retension V-belts, see 6.5.
● Breaking in
During the break-in phase, about 200 operating hours, check the oil level twice a day.
After the engine is broken in, checking once
a day will be sufficient.
3.1.6 Additional maintenance
work
After 50-150 operating hours, the following
maintenance work is to be carried out:
Before starting, make sure that
nobody is standing in the immediate vicinity of the engine or
driven machine.
After repair work:
Check that all guards have been
replaced and that all tools have been removed
from the engine.
When starting with glow plugs, do not use any
other starter substance (e.g. injection with
start pilot). Risk of accident!
Caution:
If the speed regulator has been removed, the
engine must not be tested under any circumstances: disconnect the battery!
Do not actuate the starter for more than 20
seconds. If the engine does not catch, wait a
minute then try again.
If the engine does not catch after two attempts, refer to the Diagnosis Chart (see 7.1).
● Where possible, disengage the clutch to
separate the engine from any driven parts.
● Move speed control lever 1 into idle position.
● Move cut-out handle 2 in direction of “I” and
start.
● Regarding electric starting with a solenoid,
the cut-out handle 2 is pulled in direction “I”
and held when current is flowing. The
charge pilot light and the oil pressure pilot
light go out.

● The engine temperature gauge pointer
should remain in the green sector most of
the time. It should rarely enter the yellowgreen sector. If the pointer enters the orange sector, the engine is overheating. Turn
off and establish the cause from the Fault
Table (see 7.1).

come on when the engine stops.
● Turn key counterclockwise (to position 0)
and remove. The pilot lights will go out.
● Concerning electrical shut-off or power
failure, the shut-off lever 2 is disabled by the
solenoids until the engine stops. The charge
pilot light and the oil pressure pilot light
illuminate when the engine stops.
● Turn key counterclockwise (to position 0)
and remove. The pilot lights will go out.
● Turn key counterclockwise (to position 0)
and remove. The pilot lights will go out.
If possible, do not suddenly switch off the
engine when under full load.
● Lube Oil Viscosity
– Select the oil viscosity (SAE grade) according to the ambient temperature when
starting the engine, see 4.1.2.
– Increase oil change frequency when
operating below -10 °C, see 6.1.1.
● Diesel Fuel
– Use winter-grade diesel fuel for operation
below 0 °C, see 4.2.2
● Additional Maintenance Work
– Drain the sludge from the fuel tank once a
week. (Unscrew the sludge drain plug)
– If necessary, allow the oil in the oil bath air
cleaner and the engine oil to settle at the
ambient temperature.
– Below -20 °C, after removing the starter
if necessary, smear the ring gear on the
fly wheel via the pinion bore from time to
time with cold-resistant grease (e.g. Bosch
FT 1 V 31 grease).

● Battery
– Efficient cold starting requires the battery
to be well-charged, see 6.7.1.
– The starting limit temperatures can be low-
ered by 4-5 °C by heating the battery up to
about +20 °C. (To do so, remove the battery
and store in a warm place).
● Cold Start Assistance
At temperatures near or below freezing
point, use sheathed glow plugs if necessary, see 3.2.1. This not only lowers the
starting limit temperature, but provides easier
starting at temperatures normally not requiring a starting aid.
temperature increase. As a result of this, the
engine’s maximum output, the quality of the
exhaust gas, the temperature level and, in
extreme cases, starting behaviour, are impeded. Under transient conditions, the engine can be used at altitudes up to 1000 m
and temperatures up to 30 °C. If the engine
is to operate under more severe conditions
(at higher altitudes or temperatures), it will
be necessary to reduce the injected fuel
quantity and thus, engine power.
● If you have any doubts about engine opera-
tion under these or similar conditions, ask
your engine or equipment supplier whether
the engine has been derated in the interests
of reliability, service life and exhaust gas
quality (smoke). Otherwise contact DEUTZ
SERVICE.
Lube oils are differentiated according to their
performance and quality class. In common
use are specifications named after the API
(American Petroleum Institute) and ACEA
(European Engine Oil Sequences).
Approved API Oils:
At least:CF-4
Approved ACEA Oils:
At least:E1-96
It is recommended to operate the engines
with Deutz Oil TLX10W-40FE Europe. If
this is not available, use the appropriate oil as
described above.
As the viscosity of the lube oil is dependent
on temperature, the choice of SAE grade
should be governed by the ambient temperature prevailing at the engine operating site.
Optimum operating behaviour will be attained
if you take the accompanying oil viscosity
diagram as a guide.
Should the temperature fall temporarily below the limits of SAE grade selected, cold
starting may be affected but the engine will
not be damaged. In order to keep wear to a
minimum, do not exceed application limits for
extended periods of time.
Oil changes dictated by the seasons can be
avoided by using multi-grade lube oils. Multigrade oils, particularly light-flowing oils, also
reduce fuel consumption.
* Oil change intervals, see 6.1.1
Oil capacities, see 9.1
Turbocharged engines with increased output and engines with high capacity.
For the following engines, or applications:
● for engines with an output >141kW the oils
listed in the following table are to be used.
Firstly, these oils are of high quality in accordance with ACEA or API. Additionally, these oils
are mainly partly synthetic, some even fully
synthetic (5W-40) and thus achieve thermal
stability if required for the application and
sediments are less likely if the crankcase
ventilation is closed in the turbocharger and
in the air-intake lines.

Use commercially available diesel fuel with
less than 0.5 % sulphur content. If the sulphur
content is higher, oil change intervals should
be reduced (see 6.1.1).
The following fuel specifications / standards
are approved: (also see TR 0199-3002)
● Diesel fuel
- DIN EN 590
- BS 2869: A1 and A2
(with A2, take note of the sulphur content)
- ASTM D 975-88; 1-D and 2-D
- NATO Code F-54 and F-75
- ISO 8217 DMX
- ISO 8217 DMA
● Light fuel oils
in accordance with DIN 51603
ASTM D 396; 1 and 2
BS 2869 Class D
● Jet fuel
- F34/F35/F44 (Kerosene)
- F54 (corresponds to diesel fuel in accordance with DIN EN 590)
- XF 63 (corresponds to F34+F35 with
additives)
Waxing may occur at low temperatures,
clogging the fuel system and reducing engine
efficiency. If the ambient temperature is less
than 0 °C, winter-grade fuel (suitable down
to -20 °C) should be used. (This fuel is
available from the filling stations well in advance of the cold months).
● Kerosene must be added at temperatures
below -20 °C. The relevant percentages
are given in the adjacent diagram.
● Special diesel fuels may be used in arctic
climatic zones up to -44 °C.
If summer-grade diesel fuel must be used at
temperatures below 0 °C, up to 60% kerosene can be added (see diagram).
In most cases, adequate resistance to cold
can be obtained by adding a flow improver
(additive). Please ask your DEUTZ partner.

6.3.1 Cleaning Intervals
● The amount of contamination in the cooling
system depends on the engine application.
● Oil and fuel residues on the engine increase the risk of contamination. Therefore pay special attention to leaks if the
engine is used in dusty environments.
● Serious contamination can occur, for example:
- On construction sites where there is a
high level of air-borne dust.
- In harvesting application where there are
high concentrations of chaff and chopped
straw in the vicinity of the machine.
● Because applications vary, cleaning intervals have to be determined from case to
case. The cleaning intervals given in the
table on the right can be used as a guide.

● The amount of dirt in the air cleaner depends on the amount of dust in the air and
the size of the air cleaner used. If a high
level of dust is anticipated, a cyclone-type
precleaner can be fitted to the air cleaner.
● Cleaning intervals will have to be determined from case to case.
● If dry type air filters are used, cleaning
should only be carried out according to the
service indicator or service switch.
● Air cleaner servicing is needed when

To do so:
- Undo hex. nut 5 and remove cartridge 4.
- Install new cartridge, insert and tighten
hex nut.
● Install cartridge 3, replace hood 2 and do up
clip fasteners 1.
Never clean filter cartridge with
gasoline or hot fluids.
washers from kits 6 and 7. Place removed
washers in front of or behind pulley half 2
to ensure belt alignments. Always remove
only the same number of washers from
each kit.
● For installation, now proceed in the re-
verse order. Whilst tightening the nut 1, turn
engine over simultaneously in order to
prevent crushing the V-belt.
If one belt locks or is damaged, always
replace both belts. The difference of length
between the new belts may not exceed
0.15%.

engine to cool down for at least 30 minutes.
The oil temperature should be below 80 °C.
● Check valve clearance 1 between rocker
arm / tappet contact face 2 and valve stem
3 with feeler gauge 6 (there should be only
slight resistance when feeler blade is inserted).
For permissible valve clearance, see 9.1.
● Adjust valve clearance if necessary:
- Release locknut 4.
- Use allen key 7 to turn setscrew 5 so that
the correct clearance is attained after
locknut 4 has been tightened.
● Check and adjust valve clearance on all
cylinders.
● Reinstall cylinder head cover with new
gasket if necessary.
For high output settings, the engines are
fitted with an additional oil nozzle to lubricate
bearings.

● When reassembling, ensure that clamps
make good contact. Tighten clamp bolts
hand-tight.
6.7.1.2Check Electrolyte Level6.7.1.3Check electrolyte
density
● Remove sealing caps 1.
● If testers 2 are present: Electrolyte level
should reach the base of these.
● Without testers:
The electrolyte level should be 10-15 mm
above the top of the plates.
● If necessary, top up with distilled water.
● Screw sealing caps back in.
● Measure the electrolyte density of indi-
vidual cells with a commercial hydrometer.
The hydrometer reading (see table on following page) indicates the battery’s state
of charge.
During measurement, the temperature of
the electrolyte should preferably be +20 °C.
6.7.2 Rotary Current Alternator6.7.3 Transportation Shackles
Notes on the three-phase system:
● Never disconnect the cables between
battery, alternator and regulator while the
engine is running.
● If, however, it is necessary to start and
operate the engine without the battery,
disconnect the regulator from the alternator before starting.
● Be sure not to confuse the battery terminals.
● Replace defective charge pilot lamp bulb
immediately.
● When washing the engine, cover up the
alternator and regulator.
● The habit of touching a lead against the
frame to check whether it is live must under
no circumstances be exercised with threephase electrical systems.
● In case of electric welding, connect the
ground terminal on the welder directly to
the piece being welded.
● Always use proper lifting tackle 1 when
transporting the engine.
● After transportation and before commissioning of the engine:Remove attachment
eyes 2.
● Blow air through the engine, taking particular care not to damage the cooler and
cooling fins (begin to blow through air from
the exhaust side).
Remove the dirt which has blown into the
interior space.
Using cold-cleaning compound
● Switch off the engine.
● Remove engine covers and cooling air
hood. Replace them after cleaning and
before the test run.

If the engine is to remain idle for an extended
period of time, it is necessary to take protective measures to prevent the formation of
corrosion. The preservative measures described here will protect the engine for up to
approx. 6 months. The procedure will have to
be reversed before the engine is
recommissioned
● Anti-corrosion oils to specification:
- MIL-L 21260B
- TL 9150-037/2
- Nato Code C 640 / 642
● Recommended cleaning agent to remove
preservatives:
- Petroleum benzine (hazardous materials
class A3)
● Clean engine (with cold cleansing agent if
preferred) using high pressure equipment
(see 6.8.1).
● Run engine until warm, then turn off.
● Drain engine oil, (see 6.1.2), and fill with
anti-corrosion oil.
● If necessary, clean oil bath cleaner (see
6.4.3), and fill with anti-corrosion oil.
● Drain fuel tank.
● Make up a mixture of 90 % diesel fuel and
10 % anti-corrosion oil, and refill fuel tank.
● Allow the engine to run for approx. 10 mins.
● Switch off the engine.
● Turn engine over manually several times to
preserve the cylinders and combustion
chamber.
When turning over with starter, set shutoff lever to stop position.
● Remove V-belts and store wrapped, dry
and recumbent.
● Spray grooves on V-belt pulleys with anticorrosion spray.
● Close off intake ports and exhaust ports,
possibly with plugs.
● Remove anti-corrosion agent from grooves
in V-belt pulleys.
● Install V-belt, retension after brief operation if necessary (see 6.5).
● Remove covers from intake port and exhaust ports.
