Launching
Measures in connection with recommissioning - launching
If Volvo Penta engine oil has been used during lay up
only the level needs to be checked.
If a inhibiting oil has been used, both the oil and
the filter must be changed. See under “Service
every 200 hours of operation”.
Check the tightening of all hose-clamps. Check that
all drain-cocks are closed and tight. Clean the engine
and reverse gear on the outside. Check the exhaust-
hoses. Install the impeller.
Check the turbochargers wast gate valve (TMD22) by
turning the shaft according to the picture.
Fill-up the freshwater system to the correct level. Fill-
up through the filler-hole on top of the heat exchanger
with a 50% mixture of freshwater and rust-proofing
ethylene glycol or additive.
Check the zinc ring* on the S-drive and replace if it is
consumed more than 50%. Otherwise clean the
anode (also a new one) with an emery cloth to re-
move the oxide layer. NB. This should be done shortly
before launching.
NOTE! Steel brushes or other steel tools must not be
used for cleaning, as these may reduce the galvanic
contact between the anodes and the drive.
* NB: A magnesium anode should be used when running in
freshwater.
