5. OPERATING PRECAUTIONS
•
Engine and fluid recommendations
To maintain your engine's mechanical qualities and extend its service life, we recommend that you observe the
following rules:
No Rule
Details
1
Observe
the
running-in
period: first 50 hours of
operation
A new engine is not ready to operate at its full capacity. Applying heavy loads
can reduce the engine's service life. The running-in period is intended to
gradually reduce the friction between the mechanical parts in motion, to smooth
and adapt the various parts to the contact surfaces.
2
Allow the engine to warm
up with no load
Allow the engine to warm up for 5 minutes to warm up the oil and facilitate
circulation of the oil in the engine block. Proper lubrication will limit wear of
the parts.
3
Select a fuel with a cetane
value>45
A fuel with a lower cetane value will result in poor combustion and may
generate startup errors and high amounts of smoke.
4
Empty the fuel tank
Remove fuel precipitations. Do this the first time after 50 hours of operation,
then every 300 hours.
5
Use a quality lubricant
A poor quality oil will adversely affect the engine in terms of wear of parts,
seizure, etc., and thus reduce its service life.
6
Use tap water for cooling
A water which is too hard will result in scale deposits, decreasing the efficiency
of the cooling system. This could lead to seizure of the piston.
7
Use an antirust agent in the
cooling water
Corrosion in the closed cooling circuit will accelerate corrosion of the system
while decreasing the engine's service life and the cooling efficiency (the
recommended antifreeze contains the antirust agent).
8
Use antifreeze in accordance
with the climatic conditions
Antifreeze will lower the temperature at which the coolant will solidify and thus
prevent the engine from cracking.
If you do not use antifreeze under temperatures below 0°C, be sure to drain the
cooling water after each use.
9
Do not run the starter for
more than 15 seconds
Operating the starter continuously for more than 15 seconds will result in
damage to the system.
As a general rule, be sure to always observe the maintenance and servicing guidelines.
Systematically perform the recommended checks.
•
Regular checks to be performed:
For your safety, you should regularly check certain operating points.
For more details, refer to the chapter concerning servicing performed by owner (page 16).
To choose an oil in accordance with the climatic
conditions, refer to the table below
