8. Start engine (see normal starting). Note the engine
may have to be turned over with the starter for a few
seconds before it fires.
Do not run the starter for more than 20 seconds. If the
engine has not started after 20 seconds there is
probably still air in the fuel system; disengage the
starter and continue to hand prime the engine with the
fuel lift pump lever for a further 30 seconds, then
repeat.
If engine does not start after 3 attempts then allow 5
minutes for the starter to cool down before repeating 6
(c) to 8.
Note: The starter motor windings can be burnt out
with continuous cranking.
9. If the engine does not easily start at the first or second
attempt, do not over crank the engine with the
seawater inlet seacock turned 'on'. (This problem may
have been caused by air in the fuel system, running
out of fuel, or changing a fuel filter, etc).
You should close / shut off the seawater inlet seacock
to stop seawater being pumped into the exhaust
system and eventually filling up the combustion
chamber, causing severe damage.
When you have resolved the problem, and the engine
starts you must immediately open the seacock.
CAUTION:
TO AVOID PERSONAL INJURY!
• Do not bleed a hot engine as this could cause fuel
to spill onto a hot exhaust manifold creating a fire.
• Do not mix petrol / gasoline or alcohol with diesel fuel.
This mixture can cause an explosion.
• Do not get diesel fuel or oil on the flexible mounts -
they will deteriorate rapidly if soaked in these.
• Fuel must be removed from skin to prevent infection.
