Laying up
The engine must be laid up to prevent damage if it is not used for two months or more. It is important that this is
done in the correct manner, and nothing is forgotten. For this reason, we have compiled a check list of the most
important points.
Before laying up for a long period of time, an authorized Volvo Penta workshop should check over the engine
and other equipment. Have any faults and deficiencies attended to, so that the equipment is in order, ready for
the next start.
WARNING! Before you start to do any maintenance work, read the “Maintenance” chapter carefully. This
contains instructions for doing work in a safe and correct manner.
Conservation
●
Change engine oil and oil filter.
●
Change the fuel filter. Also change the primary
fuel filter, if fitted.
●
Warm the engine up.
●
Check that the coolant offers sufficient frost pro-
tection. Top up as necessary.
IMPORTANT!
Anti-corrosion mixture does not
offer any protection against frost. If there is
any risk of frost, the system must be drained.
●
Drain any water and contamination from the fuel
tank. Fill the fuel tank completely, to avoid conden-
sation.
●
Clean the outside of the engine. Do not use a
power washer. Touch up paint damage with Volvo
Penta original paint.
●
Disconnect the batteries. Clean and charge the
batteries. NOTE! A poorly charged battery can
freeze and burst.
●
Spray the components of the electrical system
with water-repellent spray.
Removing conservation
preparations
●
Check the oil level in the engine. Top up as neces-
sary. If special conservation oil has been put in,
this must be changed together with the oil filter.
For the correct grade: Please refer to the “Mainte-
nance, lubrication system” chapter:
●
Close/tighten drain taps/plugs.
●
Check the drive belts.
●
Check the condition of all rubber hoses, and re-
tighten the hose clamps.
●
Check the coolant level and anti-freeze. Top up as
necessary.
●
Connect the fully charged batteries.
●
Start the engine. Check that there is no leakage of
oil, fuel, coolant or exhaust gas, and that all con-
trols function normally.
