Skin must be thoroughly cleaned in the event of contact with diesel fuel. Fuel Supply Connections Engines are supplied with 8mm compression fittings. The installer must ensure that when connections are made, they are clean and free of leaks. The Isuzu marine propulsion package is supplied with 2 dipsticks, one for the engine and one for the gearbox. Ensure dipsticks are returned and secure after checking, if not oil leaks can cause infection when touched. Do not remove dipsticks whilst engine is running, as this can cause oil to blow out.

Note: If the alternator warning light is still on then increase the engine speed to excite the alternator, then return to idle. The light should then go out. The Isuzu Marine engines are fitted with “Quick Heat” Glow Plugs and the Pre- Heat time tends to be shorter than on other Indirect Injection engines. These Glow Plugs can reach tip temperature s of 800 to 900°C within seconds and therefore prolonging the Pre-Heat cycle can lead to premature plug failure. Continuous engagement of the starter to the flywheel ring gear without giving them a break will result in the damaged starter pinion gear and flywheel ring gear. Crank for no longer than 20 seconds, with a 20 second break between... -

When checking Daily or every 8 hours running the engine oil level, do so before starting or more than five minutes after • Check engine oil level stopping. • Check gearbox oil level, see gearbox manual . To check the oil level, draw out the dipstick, wipe clean, re-insert it and • Check coolant level draw it out again. Check to see that the oil level lies between the two • Check drive belt tension, adjust if necessary marks. • Ensure raw water inlet strainer is clear (heat exchanger cooled engines 2.

Calorifier Position The ISUZU Marine range has been developed to operate with approximately 3m of piping between the engine and Calorifier, with a minimum number of bends and restrictions in this pipework. We recommend the Calorifier Inlet and Outlet connections be no more than 300 to 40mm either above the top of the engine or below the bottom of the engine sump. Provided these criteria are applied and the system is fully bled of air, then satisfactory performance should result. Both Feed and Return connections are situated on the engine side of the Thermostat and water is therefore allowed to circulate around the Calorifier Circuit at all times. It should be noted that during long periods of engine operation, when...
