PROCEDURE
1 Make sure that there is always a safety person on the outer side of the engine.
2 Wear the correct safety equipment.
3 For a DF engine, obey the safety rules for natural gas, refer to section 2.2 Safety
precautions and safety rules for natural gas.
4 Release the pressure in the air spring air pipe to open the exhaust valves.
5 Make sure that the starting air supply pipe has no pressure (ie starting air shut-off valve
30-4325_E0_1 is closed, ball valves 30-8605_E0_6 and 30-8605_E0_7 are open).
6 Engage the turning gear and lock the lever in this position.
NOTE: Other ships in the water cause currents, which cause the movement of the
propeller and the engine. The engine and propeller cannot move when the
turning gear is engaged.
7 If applicable, open the indicator valves or the relief valves on the cylinder cover.
8 Make sure that there is sufficient air in the engine spaces, eg use a ventilator.
9 Go into the engine spaces and do the work very carefully.
