13) Repair all the damage and leaks found during the previous operation period and
the checks made after shut-down.
14) Do all scheduled overhauls and obey the general guidelines for maintenance
(see the Maintenance Manual 0011−1 and 0012−1).
15) When the auxiliary engines and boilers do not operate and there is risk of frost,
fully drain all of the cooling systems (in such conditions, protect the drained
systems from corrosion).
16) In the power supply box E85, set to off the circuit breaker to disconnect electrical
power to the engine control system (ECS).
17) In less than 48 hours after you have completed the steps 1) to 16), do step 18)

18) Open the covers on the rail unit and look for signs of condensation and corrosion.
2.2 Procedures and Checks
WARNING
Injury Hazard: Before you operate the turning gear, make sure
that no personnel are near the flywheel.
Do steps 1) to 13) below each week:
1) Make sure that the indicator valves are open.
2) use the turning gear to turn the engine until the piston is at 60_ before or after
TDC (look on the flywheel). Cylinder lubricating oil can then flow directly into the
piston ring pack.
3) In the LDU−20, get the MAIN page (see 4002−2, paragraph 3.3).
4) Use the rotary button to select Cylinder Lubrication. The display shows the CYL.
LUBRICATION page.
5) In the Manual Lub. To Cyl. # field, select the applicable cylinder number.
Note: The lubricating oil pump and must operate (see 0140−1 Prepare the
Cylinder Lubricating System and 7218−1 Cylinder Lubrication).
6) Use the turning gear to turn the engine two full turns to apply the cylinder
lubricating oil to the cylinder liner wall.
The recommended intervals are:
D Weekly in dry climates
D Daily in damp climates.
7) Stop the engine each time in a different position.
8) Open the covers on the rail unit and look for signs of condensation and corrosion.
9) If there are signs of corrosion, carefully clean the affected parts.
10) Apply an anti-corrosion oil to give protection.
11) Decrease the intervals of post-lubrication.
12) Apply oil as a spray to the dry parts.
Do the step below every two weeks:
1) Start the auxiliary blowers for a short time to protect the bearings from corrosion.
If this is not possible, manually turn the impeller several times.
3. Condition Two
If the engine must stop for a long period, it must be thoroughly cleaned and preserved
on the inside and the outside (ask for the preserving instructions from Wärtsilä
Services Switzerland Ltd or Winterthur Gas & Diesel Ltd).
