CHECKS BEFORE RUNNING
Before running, ”Daily maintenance” as described in the maintenance sched-
ule should be carried out, see page 25.
STARTING THE ENGINE
If the fuel tank has been run dry or if the engine has not been used for a long
time, bleed the fuel system, see page 41.
Only start the engine in a
properly ventilated area.

To limit white smoke, the engine should be run at low speed and under mod-

Note: Use only start aids recommended by Scania.
- The starter motor may only be used for 30 seconds, after which it must
rest for 2 minutes.

Note: If the engine is equipped with an INTERLOCK switch, this
switch should be depressed and held down until the oil pressure
has reached a sufficiently high level.
- Run the engine until warm with a light load. A light load on a cold
engine gives better combustion and faster heating than warming up with
no load.

2600-3000 rpm
red area:
prohibited engine speed
Cruising speed
Important: To achieve good operating economy and long engine life,
cruising speed should be about 200 rpm below maximum
engine speed.
Coolant temperature
Normal coolant temperature when the engine is running should be 70 - 90 °C.
DEC2: If the temperature is too high, 98 °C or above, the control system will
reduce engine power (Power -) in order to lower the temperature.
If the temperature continues to rise, the engine will be stopped automatically
(Shutdown) at 103 °C.
Excessively high coolant temperature can damage the engine.
If run for extended periods under an extremely light load, the engine may
have difficulty in maintaining normal operating temperature. However, the
temperature will rise to a normal level again when the load on the engine is
increased.

Min. oil pressure:

0.7 bar
At speeds below 800 rpm, the gauge may show low oil pressure without there
being a fault.
Oil pressure below 0.7 bar at speeds above 800 rpm will cause engine dam-
age. The engine must be stopped immediately.
Charge warning lamp
If the lamp lights during operation:
Check/adjust the alternator drive belts as described under maintenance point
See page 45. If the charge warning lamp is still lit, there may be a fault in the
alternator or in the electrical system.
STOPPING THE ENGINE
1. Allow the engine to run without load for a few minutes if it has been run
with a high continuous load.
2. Stop the engine with the stop button. Keep the stop button depressed
until the engine is completely stationary.
There is danger of turbo damage

LUBRICATION OIL SYSTEM
OIL GRADE
The engine oil should at least meet the requirements for one of the following
oil classifications:
-Service CE or CF as per API
-CCMC - D5
-Acea E3-96
- Check with your oil supplier that the oil meets these requirements.
Additives must not be used.
- Specified oil change intervals apply under the provision that the sulphur

next oil change.
- At very low outside temperatures: Consult your nearest Scania repre-
sentative to avoid starting difficulties.
Oil analysis
Some oil companies can offer analysis of the engine oil. This analysis meas-
ures the oil’s total base number (TBN), total acid number (TAN), fuel dilu-
tion, water content, viscosity and the content of wear particles and soot in the
oil.
The result of a series of analyses forms the basis of establishing a suitable oil
change interval.
If the conditions are changed, a new oil analysis programme must be under-
taken to establish a new change interval.

1. Daily:
CHECKING OIL LEVEL
Before checking oil level: Let the engine remain stationary for at
least 1 minute.
- The correct level is between the marks on the dipstick. Top up when the
level is at the lower mark.
- Correct type, see ”Oil grade”, page 26.
2. Every 200 hours:
OIL CHANGE

conditions, in an especially dusty environment or if the deposits in
the centrifugal cleaner are thicker than 20 mm: Change the oil

more often.
Min. 25 dm3
- Pump out the oil using the oil bilge pump when the engine is warm.
- Fill with new oil.
- Check the level on the dipstick.
Note: Observe the applicable environment protection regulations when
disposing of the old oil.

3. Every 200 hours:
CLEANING THE OIL CLEANER
(at same time as oil change)
- Unscrew the nut and remove the cover.
Open the cap carefully. The
oil may be hot.
- Lift out the rotor and slacken the nut for the rotor cover three turns.
- If the nut is stuck:
Clamp the nut, absolutely not the rotor, in a vice and turn the rotor three
turns by hand or using a screwdriver.
- Gently tap the nut using your hand or a plastic hammer so that the rotor
bowl becomes detached from the bottom plate.
- Undo the nut and remove the rotor bowl.
- Carefully prise the strainer loose from the bottom plate.
- Scrape away deposits from the inside of the rotor bowl. If there are no
deposits, this shows that the cleaner is not working.
- If the deposits are thicker than 20 mm: Clean more often.
28
2001-05:1
- Clean all the parts in diesel fuel oil.
- Place the O-ring in position in the rotor bowl. This must not be damaged.
Change if necessary.
- Assemble the rotor
- Tighten the rotor nut hard by hand
- Refit the rotor.
- Check that it turns easily.
- Check that the O-ring in the bowl is not damaged.
A hardened or damaged O-ring should be replaced.
- Screw down the bowl hard by hand.
If the nut is tightened using a tool, the rotor shaft, nut or bowl may be
damaged.
Operational test
The rotor turns very quickly and should continue to rotate when the engine
has stopped.
- Stop the engine when it is warm.
- Listen for the whirring from the rotor or feel whether the cleaner hous-
ing is vibrating.
The rotor normally rotates for 30 - 60 seconds after the engine has stopped.
If not: Dismantle and check.
2001-05:1
29
4. Every 200 hours:
CHANGING THE TURBO FILTER
(at the same time as the oil change)
- Remove the old filter and discard it according to environmental require-
ments.
- Oil the rubber gasket and fit a new genuine Scania filter.
- Tighten the filter by hand.
Never use tools as the filter may sustain damage, interfering with
circulation.
- Start the engine and check for leaks.
If the deposits in the centrifugal cleaner exceed 20 mm, the turbo filter
must be changed more often, at the same time as cleaning the centrifugal
filter and changing the oil.
Always collect oil in a suitable
container to avoid spillage when
renewing the oil filter.
Dispose of used filters through
an authorized waste disposal
contractor.
COOLING SYSTEM
5. Daily:
CHECKING COOLANT LEVEL
- Open the expansion tank cap and check the coolant level.
- Correct level: (Scania expansion tank)
Carefully open the cap.
Hot water and steam
- Cold engine: The coolant should reach up to the bottom of
the filler pipe.
may blow out.
- Warm engine: The coolant should be 10 - 20 mm above the bottom
of the filler pipe.
- Other types of expansion tank according to the installer’s instructions.
- Top up coolant as necessary, see point 6.
Note: When filling large amounts of coolant:
Always top up with ready mixed
Never pour cold coolant into a warm engine.
coolant.
This could crack the cylinder block and head.
30
2001-05:1
6. Every 400 hours:
CHECKING CORROSION
PROTECTION RODS
- Drain the seawater circuit and check the corrosion protection rods
(sacrificial anodes). Location as per drawing on page 11.
- Scrape away all loose material from the anode.
- Change if less than half the rod remains.
New rods are 55 mm long, diameter 17 mm.
If the corrosion protection rods are highly eroded, they should be checked
more often, e.g. every 200 hours.
7. Every 400 hours:
CHECKING SEAWATER PUMP
IMPELLER
- Close the bottom valve if the seawater pump is below the water line.
- Drain the seawater circuit.
- Remove the cover from the seawater pump.
- Check that the impeller vanes are not worn or damaged.
If the impeller often requires changing, it is necessary to improve
the purity of the seawater.
Changing the impeller
- Extract the impeller using extractor 98 482 (Scania special tool).
- Fit a new impeller and the cover. Check that the cover seal is not
hard or damaged.
Note: A spare impeller should be carried on board.
- The impeller can become deformed after long periods of standstill.
Change before starting or remove the impeller before long periods of
disuse. Also see “Mothballing”.
