RISK OF INJURY CAUSED BY PINCHING OR JAMMING WHEN WORKING ON LOADED SPRINGS OR SPRING BODIES
- AS00.00-Z-0001-01A
Use only approved clamping devices; shield off hazard area if necessary. Inspect special tools for damage
and proper operation (visual inspection). Wear protective gloves.
Risk of pinching and jamming body parts when working on pre-loaded components.
When loosening or removing components that are under significant load, there is a risk of serious injury if
non-approved if clamping devices are used.
Safety instructions/precautions
When conducting repair work on springs, spring bodies, spring-type actuators and other components under
tension use approved clamping devices only .
Spring compressor
The spring compressor should never be clamped or released using an impact wrench.
Check clamping devices
The spindle must be undamaged and allow ease of movement.
The clamping plates must not be deformed.
Note arrangement of clamping plates to springs.
If the device is damaged or malfunctioning, it must be returned to the manufacturer.
The coil diameter of the spring should match the groove in the clamping plate.
Wear protective gloves during all operations.
RISK OF INJURY. SKIN OR EYE INJURIES MAY RESULT WHEN HANDLING HOT OR GLOWING OBJECTS. - AS00.00-
Z-0002-01A
Wear protective gloves, protective clothing and (where necessary) safety glasses.
Risk of injury
Unprotected contact with hot or glowing objects may cause severe burns to the skin and eyes.
If glowing objects come into contact with water, hot steam or hot splashing water may result in severe skin and
eye burns.
Severe and possibly permanent injuries may result if hot or glowing objects come into contact with unprotected
skin or eyes.
Fire ma
y result if glowing objects come into contact with flammable materials or substances.

For these vehicles the service sheet for the Active Service System (ASSYST) and the maintenance manual
volume 4 apply.
With the ASSYST service sheet the previous distinction between care service and maintenance service no
longer applies. Instead, the service category A (minor service) and service category B (major service) have been
introduced.
The service scopes for each model series can be seen in the respective valid service sheet.
The order no. is stated on the particular SERVICE SHEET.
On manual transmissions, automatic transmissions, transfer cases, front axles and rear axles the service item
"Check fluid level" has been replaced by an inspection of all visible parts for leaks.
In view of the fact that these components are not oil consumers, as is the case for the engine, a loss of oil can
occur only to the outside.
If any leaks are present, the procedure, as before, is to determine the cause and to rectify it subject to a separate
repair order.
The service operations carried out should be documented in the boxes in front of the operation titles. It is
essential to ensure that the specified service operations are carried out in full.
An indication is given in the boxes after the operation titles of which service operations should be carried out
for service category A (minor service) or service category B (major service). Enter a cross behind these boxes to
identify any items which are not in proper order when the vehicle is received.
Additional operations should be defined by the service adviser in agreement with the customer and an indication
should be made on the service sheet whether these additional operations are to be carried out.

Overview Section 5). However, it should always be remembered that anticorrosion/antifreeze
a
gents or coolants conforming to Sheet 325.3 and 326.3 must not be mixed with those conforming to
Sheet 325.0 or 326.0 or 325.2 and 326.2.
2.3 Coolant additives for commercial-vehicle en
gines without antifreeze specifications (refer to item
1.1.2) (not: BR 600, BR 100 and BR 200)
In those application cases where no antifreeze is necessary, coolant for commercial-vehicle engines as
under item 1.1.2 can be mixed to suit. It is impossible to cite generalized mixing proportions because the
application concentrations of products included in Sheet 312.0 may be different. If the tolerances exceed
or fall below those given in Sheet 312.0, then appropriate adjustments must be made. The coolant's
boiling point is only insignificantly increased by these additives. The starting-off water underlies the
more stringent regulations as under point 1.2.3. The usage period for this coolant is shorter than usual (see
position 3). If it is necessary to refill, the same product must be used and at the same concentration level.
The blending of different products is not permitted as stated in Sheet 312.0.
2.4 Coolant regulations for commercial vehicle engines (exception, not for engines OM 500, OM
900, OM 457 and OM 460)
In the event that neither an approved anticorrosion/antifreeze agent is available, nor a coolant additive in
accordance with sheet 312.0 and if temperatures do not drop below freezing then it is possible in this
exceptional case to use a coolant refining agent to 1 vol % if it is approved in sheet 311.0 (soluble
corrosion protection oil). This will not raise the boiling point. The starting-off water itself underlies the
more stringent regulations as under point 1.2.3.
The period of usage for this coolant, which may only be used in exceptional circumstances, is shorter than
usual (refer to position 3).
Water that is too hard may impair the emulsion resistance, with the result that the emulsion
breaks down (oil separation) and the engine's water jackets are contaminated.
2.4.1 Applying water refining mixture
When carrying out a new filling (initial filling or filling after a cleansing operation) an emulsion of 1.0-
1.5 vol % should be used. When refilling, an emulsion of 0.5-1.0 vol % should be used. Concentrations
that are too high (>1.5 vol %) do not improve the corrosion protection capability and may exert a negative
influence on seals and hoses.
3.Monitoring coolant operation
It is very important to monitor the coolant constantly if the engine is to run trouble free.
The concentration level should be checked every six months.
The inspection should be conducted with suitable apparatus. If, when monitoring the concentration of the
coolant, it is determined that the concentration of anticorrosion/antifreeze agent has reached 40 vol.% or
less or an antifreeze protection of -28°C is no lon
ger guaranteed, the concentration must be increased to

Notes on HHT previous knowledge diagnosis
IC


HHT :

The instrument cluster and active service system (ASSYST) sub-

function are checked with HHT, there being the choice of the

following functions for this:
1. Control module version

2. Fault memory

3. Actual values

4. Actuations

5. Control module adaptation

Additional information on test items 2, 3 and 5 can be called up using

the INPUT key


Control module adaptation

The following alternatives are available in the HHT under control

module adaptation:

1.)
Read out coding and transfer to new instrument cluster. IC and

ASSYST.

2.)
Read out/change codings e.g.:

Engine and national variants,

version of fuel tank,

special equipment etc.
3.)

Settings:

1
Clock

2
Put forward kilometer reading

3
Put back kilometer reading

4
Oil change

5
Reset oil change initiated inadvertently

6
Active Service System

7
Enter times with battery disconnected

8
Set minimum oil warning


Before replacing a defective instrument cluster, readout the existing

variant codings (driving data and instrument cluster data) and store in
the HHT on an interim basis. Read in the values stored on an interim

basis again after installing the new instrument cluster.

If it is not possible to read out the stored variant coding, all variant

codings must be input manually (menu-assistance in HHT).

When installing an instrument cluster on an experimental basis, do

not put forward the kilometer reading as it cannot be put back later.
