Preparations for standby1. The engine must be warmed by circulating hot water through the jackets. 2. The supply tanks, filters, valves and drains are all to be checked.3. The lubricating oil pumps and circulating water pumps are started and all the sight glasses observed.4. All control equipment and alarms are checked5. The indicator cocks are opened, the turning gear engaged and the engine turned through 2/3 revolutions so that if there is water in the cylinders it will be forced out.6. The fuel oil system is checked and circulated with hot oil.7. The turning gear is removed and the engine is turned over on air before closing the indicator cocks.8.
